Probably the first question you have is "how much will this cost?"
The homemade trail camera is basically divided into two types. A 35mm Trail
Camera or a Digital Trail Camera. The 35mm trail camera usually
cost less to build then the digital trail camera. The final costs will depend on
how the needed components are obtained and exactly which components are
trail cameras can be built for under $100 and advanced models can cost up to
$200. The basic digital trail camera can cost $200 and advance models could cost
over $300.The finished price really depends on how creative and ingenious you
are, what extra "bells and whistles" you add, and can vary in both extremes. The
finished trail camera can be commercial quality or something only the owner
loves. The pride, knowledge, and understanding of how to build, and how to
repair your trail camera are priceless. SO LETS GET STARTED.

The above mentioned price differences,
35mm vs. digital, should start to direct you into which trail camera you prefer
to build. Both are built relatively the same, but it is a veteran recommendation
to start with a basic 35mm and achieve success before trying more advanced
cameras. With this in mind, we'll do our step by step procedure for
a 35mm trail camera and add notes for digital.
The hands down favorite 35mm camera is the Canon Sure Shot Owl PF. Either in the
date or non-date version. This camera boasts a 33' flash range compared to other
35mm cameras that average 15'. The camera is out of production as of July 2003,
ebay search will produce this
for quite awhile. National retail stores, Target, Sears, and Kmart have carried
this camera along with many on-line camera retailers. A search will produce many
sources and retail price averages $50 for the date version. Similar Canon
cameras do work as well. To list models: Canon Sure Shot Owl, Canon Sure
Shot BF, Canon Snappy EL, Canon AF-8, Canon BF-8, Canon Snappy LX, Canon Snappy
LXII, Canon Snappy QT. Many of these are also out of production, but can be
found using the same methods. Most models come in date or non-date versions.
There are also different name brand 35mm cameras that will work, and asking in
forum will produce the models and the required modifications needed to use
the chosen camera in a homemade trail camera.
Olympus D-370 and Olympus D-380 are the preferred
cameras. Both models are currently out of production, but an
ebay search will continue to provide cameras. The D-380 is a later model and
has upgraded features over the D-370. Notable improvements are the higher ISO
rating of the D-380 which translates into longer flash range for night pictures.
Retail price for the D-370 is $80 to $100 and for the D-380 is $120 to $150.
There are alternate name brand digital cameras that will work, and asking in the
forum will produce models and the required modifications needed.

motion sensor is used to trigger the camera to take a picture and can come in
many different configurations. Some refer to this part of the trail camera as
the PIR (pyroelectric infrared sensor). The basic choices are to purchase a
commercial motion detector, designed for a light or an alarm, and modify the
sensor to work as a trigger for the camera, OR to purchase a complete trail
camera sensor board (aka: complete board) and avoid some of the modifications
needed with the commercial sensor. The difference is in the cost and personal
electronics experience. A basic commercial sensor and associated parts can cost
as little as $10 and require 1 to 2 hours to modify with some basic electronics
knowledge. A complete board will cost $50 to $80, but requires very little if
any modification and electronics "know how". The basic driving force in building
a homemade trail camera is cost, so the converted commercial motion detector
will be covered first.
A.) Commercial Motion Sensors.
Commercial motion detectors utilized in porch lights and alarms, which
require heat and motion to activate, are the sensors that will work for a
homemade trail camera. The appropriate sensors technical term is dual element
detector which means the sensor requires both heat and motion to activate.
Single activating sensors such as ultrasonic, which activate by motion only,
would make poor sensors for a homemade trail camera. The appropriate sensor is
purchased as a complete light or alarm and then the motion sensor parts are
removed and transformed into a sensor that will trigger the camera and operate
off of battery power. The top three commercial sensors used are the Regent 110
Degree Motion Light (aka: MS20), the Radio Shack Motion Alarm (aka: 49-426) and
the X10 RF Motion Sensor (aka: X10). Other "shelf" sensors are in use and can
work, but these three are the most commonly used and will provide the best
chance for member support if problems arise.
The MS20 sensor is part of
a motion activated flood light sold under the Cooper Lighting name and retailing
for around $10 for the complete package. The flood light was stocked by Walmart
nationally, and are still available in certain locations. The modified sensor
alone will work for the PIR portion of a trail camera, if you wish for a basic
setup in which the sensor triggers the camera directly. The MS20 can also be
connected to a PIC Chip Timer which will add many useful options to a basic
trail camera, and required features for a digital trail camera. (See
SENSOR OPTIONS below). The negative aspects of the MS20 sensor are the over
sensitive design of the circuit resulting in potential false pictures and the
high battery power drain without further modifications. (See
POWER CHART below). Power reduction and other MS20 modifications can be
found on the
Homemade Trail Camera Links page under Trail Camera Mod. Instructions.
The 49-426 sensor is part
of a motion activated alarm stocked at most Radio Shack Stores and also
available on-line through radioshack.com. The alarm retails for $25 and is on
sale occasionally. The sensor is very energy efficient, so power reduction
modifications are not needed. (See
POWER CHART below). The modified sensor alone will work for the PIR portion
of a trail camera if you wish for a basic setup in which the sensor triggers the
camera directly. The 49-426 can also be connected to a PIC Chip Timer which will
add many useful options to a basic trail camera, and required features for a
digital trail camera. (See
SENSOR OPTIONS below). The negative aspect of the 49-426 is the initial cost
of the base sensor.
The X10 sensor is part of a
motion activated transmitter used within the X10 home security system. The
needed sensor components are included within three different transmitter models,
the Active Eye (#MS-16A), Eagle Eye (#MS-14A) and the Hawk Eye (#MS-13A). The
transmitters retail for $20 to $25 each, and are occasionally offered at "two
for one" or "three for one" specials through X10.com. Signing up for the
promotional e-mail notification is the best way to find out about the X10.com
specials. The transmitters are also available thru an
ebay search with multiple units usually for sale with a one time freight
charge. The sensors are very energy efficient, so power reduction modifications
are not needed. (See
The modified sensor alone will
not trigger a camera directly, but requires an additional pc board with a
dual optocoupler to operate the camera functions. The optocoupler (opto)
receives the signal from the X10 sensor and triggers the camera accordingly.
This pc board w/ opto is commonly referred to as the X10 Opto Board, and
combining this board with the modified sensor and a programmed X10 PIC Chip will
convert the X10 sensor into a full options 35mm or digital trail camera sensor.
The X10 Kit contains all the above mentioned X10 components and the kits are
available from Hag's House

B.) Complete Trail Camera
Motion Sensors. The complete trail camera controller (aka: complete board)
is the motion sensor part of the homemade trail camera, and more importantly, is
designed to require very little if any modification to the sensor itself. The
complete board can, and usually will come loaded with other features and
functions; or it may be designed as a simple trigger board for just the camera.
The complete boards are specifically designed for a trail camera application and
usually perform better then the commercial sensors designed for lights and
alarms. The true value of the complete board is realized by the builder who
lacks any real electronics experience needed to modify commercial sensors. No
need for any serious modifications will almost guarantee the success rate to a
finished and properly functioning homemade trail camera, and should also
alleviate most trouble shooting.
The only real downfall of the
complete board is the initial cost. The boards will retail for $50 a piece on a
quantity buy, and up to $80 each for an individual board. The boards are usually
created and tested by the electronically gifted members of the forum, and all
developers provide outstanding tech. support. The following are probably the
most widely used complete boards.

PIC Chip Timer?
PIC Chip Timer is an upgrade component for a basic motion sensor which will add
user preferred functionality to a finished trail camera. The timer features a
custom programmed microcontroller chip, or PIC chip, that takes the trigger
signal from the sensor and activates the camera according to the program on the
chip itself. The programmed PIC chip controls all features of the trail camera
and can include basic items such as multiple delays, multiple refreshes, sensor
test mode, and advanced items such as double picture mode, day / night / both
select ability, and automatic return to normal mode from test mode. The PIC
Chip Timer is used mostly with the RS-426 and MS20 sensors and converts these
sensors to a full feature trail camera controller. PIC Chip Timers for the
RS-426 and the MS20 are available from Brian Gennings (member name: Brian) with
board information and/or purchasing done by contacting him via
email. All available options and tech. support are provided through Brian
and/or asking members in the
An understanding of common terms
used in association with trail camera sensors will aid you in determining which
options and features are important for "your" sensor. Some features are required
for the finished trail camera to work properly, and others are "bells and
whistles" added to enhance the performance of the trail camera sensor. Common
terms used within the
forum will begin to make sense if a basic understanding of "trail camera
lingo" is interpreted.
Homemade Trail Camera 'Lingo' -
What does that word mean??
Camera Related Terms:
This refers to the camera's programming options and possible settings. Selecting
the correct camera settings to correspond to the trail camera's motion sensor
can be critical and some PIC chips may require certain camera settings to
achieve the best performance possible.
Shutter or Camera Sequencing?
This refers to the actual sequence the chosen camera goes thru after a signal
has been received to take a picture. This timing sequence for a chosen camera
is needed when programming the PIC chips to the correct settings so the camera
operates properly. Sequencing items can include: shutter’s hold timing, on-off
timing, record timing (digital cameras), refresh timing, etc.
This refers to a pcb board and ribbon cable assembly created for the Sony
digital cameras that’s inserted next to the control ribbon cable of the camera.
Using the shutter assembly aids and eases the conversion of the Sony cameras
into a usable digital trail camera.
washed out effect of pictures overexposed to the flash of the camera when the
flash is redirected in front of the shutter during a picture. Flash bleed often
occurs if a common medium (single piece of glass) is placed over the flash and
shutter holes of the trail camera enclosure. The flash will use the medium to
redirect the light in front of the shutter during a picture. Flash bleed can
also occur from the light trapped within the trail camera enclosure and an
insufficient seal between the flash and shutter openings of the camera.
This refers to the state of the camera itself while operating as a trail
camera. The camera itself is always on and controlled by the programming of the
This refers to the state of the camera itself while operating as a trail
camera. The camera is off and controlled by the programming of the PIC chip.
When the sensor is triggered the PIC chip turns the camera on and shutters a
picture. The camera remains on for a specified time interval to record the
picture and then is powered off by the PIC chip.
This refers to an additional flash unit added to a homemade trail camera to aid
in nighttime photo quality.
Power Slave Controller?
This refers to a slave flash controller produced by Jon5ja that connects to the
slave flash and integrates with the flash of the camera to fire the slave flash
at the correct time. The power slave controller also meters the daylight and
dark to disable or enable the slave flash when needed.
Chip Related Terms:
Programmable Integrated Circuit Chip (the IC Chip itself) used to control the
functions of the camera along with various features listed below.
This is the time interval at startup from when the power is initially turned on
to the sensor, until the PIC chip automatically switches to standby mode or
normal operating mode. The sensor itself is inactive during initial delay. The
initial delay allows the sensor to stabilize and prevents false triggers at
This is the time interval after initial delay in which only the push button
switches are active, Once a push button is pressed, the standby mode is
cancelled and the PIC chip is in either walk test mode or normal operating mode
depending on which push button was selected. This time interval will time out
and the PIC chip returns the sensor to normal operating mode. Standby mode is
only accessible by going thru initial delay.
This is when the PIC chip signals all the sensor’s activity by lighting an LED.
The walk test mode will time out after a set time of inactivity and the PIC chip
returns the sensor back to normal operating mode. Walk
test mode in only accessible after initial delay times out.
This is the time delay configured by changing the delay settings of the PIC chip
itself. It is the time measured from when the relay for taking a picture turns
off to when you can take another picture. Delay mode is only accessible after
initial delay times out.
Double Picture Mode?
This is the timed, automatic signal from the PIC Chip to take a second picture
after an initial sensor triggered picture was taken.
Adjustable Refresh Mode?
This is a 500millisecond pulse generated at a set time by the PIC chip to help
the camera remain in a “ready” mode. In appropriate digital cameras the refresh
keeps the digital camera awake, and does not allow auto shut down to occur. The
digitals are able to reach the camera’s sleep mode setting with the 2.5-hour
refresh, which in turn uses less power and still refreshes soon enough so the
digital does not automatically shut off. The digitals do not reach sleep mode
with the 2.5-minute refresh, which in turn uses more power, but faster shutter
speeds are realized to capture faster moving animals. Adjustable refresh mode is
only accessible after initial delay times out.
Normal Operating Mode?
This is when nothing is happening except the refresh countdown of the set
refresh time. The PIC chip is ready to be triggered by the sensor so it can
take a picture. It is also ready to receive any commands from the test button
or the delay button. Normal operating mode is only accessible after initial
delay times out and time expires in either standby mode or walk test mode.
Normal operating mode is the default mode of the PIC chip and the chip will
return to normal operating mode when all time outs expire. Normal operating mode
is only accessible after initial delay times out.
This is when the PIC chip is shutdown except for a low power internal
oscillator, which keeps up with the timing or interrupts generated for the PIC
chip. By shutting down the main oscillator the PIC chip draws less current. (4
to 5uA in sleep mode.) Sleep mode is inaccessible and automatically switched to
by the PIC chip itself.
Motion Sensor, Complete Board or Controller Board Related Terms:
The actual infrared sensor component located on the motion sensor or controller
pcb board used within the homemade trail camera. The actual sensor is the ¼”
round component with the rectangle glass window. The complete board is often
referred to as the IR sensor or the PIR. Both terms refer back to the actual
The IR transmittable poly plastic material with a stamped fresnel lens pattern
designed to be installed at a set focal distance and center point from the IR
sensor. The fresnel lens focuses the IR signal to the IR sensor itself.
The approximate time delay after a sensor is triggered
and before it can be triggered again. This delay is the time needed for the
sensor to reset itself and may vary slightly.

The next component that will require room within the trail camera enclosure is
the battery (or batteries) and holder. The chosen battery configurations will
operate the motion sensor and/or camera for an acceptable period of time before
replacement is required. The basic understanding of how the sensor and camera
operate during idle and during a "trigger" will help in selecting battery
requirements. Let's start with the sensors and then the cameras.
Most of the sensors listed have a
metered value which represents the idle current draw of the sensor; after the
sensor is modified for a trail camera. It's basically the battery power consumed
when the sensor is active, stable and idle. The metered values may vary from
sensor to sensor and will also vary if additional components are added to the
sensor (ie: PIC Chip Timer, etc.).
Some of the sensors listed will
also have a metered value which represents the "trigger" current draw of the
sensor. This is the battery power consumed when the sensor is active and
triggered. It is also accepted that the trigger value is basically a capture
reading of a short duration and may vary between sensors in value and duration.
The "field value" most accepted
for comparison is the idle current draw value metered from the sensor when
active, stable and idle. Using this value for the particular sensor of choice
will aid in selecting an appropriate battery size to operate the sensor for an
estimated time period. The estimated time period of the batteries life truly
depends on many factors; number and frequency of triggers, ambient temperature,
and initial freshness of the batteries are just a few factors that can greatly
affect the actual operating life of the batteries, compared to estimated
operating life. To set a benchmark reference it's accepted that calculated
values of battery life using the metered idle current draw of the sensor is
realistically twice to three times greater then actual "field results". To give
an example lets look at the X10 sensor.
The modified X10 sensor connected
to the X10 opto board meters an idle current reading of 60uA. Using basic
"fresh" alkaline batteries for this example the "common" mAh rating for
batteries can be easily obtained from manufacturer's websites.
Since the recommended power source
for the X10 is 6V to 9V, either a single 9V battery or a combination of (4) 1.5V
batteries in series will be needed. The "common" mAh ratings for the alkaline
batteries are as follows:
(1) 9 Volt Alkaline Battery =
(4) AAA 1.5V Alkaline
Batteries = 1,190mAh
(4) AA 1.5V Alkaline Batteries
(4) C 1.5V Alkaline Batteries
(4) D 1.5V Alkaline Batteries
The formula is Battery Life =
Battery Ampacity (mA) / Current Draw (mA)
With the conversion of the idle
current reading to mA (60uA = .06mA) we yield the following results:
(1) 9 Volt battery (565mAh /
.06mA = 9,416 hours or 392 days)
(4) AAA batteries (1190mAh /
.06mA = 19,833 hours or 826 days)
(4) AA batteries (2707mAh /
.06mA = 45,116 hours or 1,879 days)
(4) C batteries (7935mAh /
.06mA = 132,250 hours or 5,510 days)
(4) D batteries (17,100mAh /
.06mA = 285,000 hours or 11,875 days)
These values represent the
theoretical battery life for the X10 sensor and X10 opto board using the
different battery combinations. Using the knowledge that "field results" are 1/2
to 1/3 that of the calculated value for battery life. We can now estimate the
battery life for the X10 sensor w/opto board at:
(1) 9 Volt battery (392 days /
2 or 3) = (196 days to 130 days)
(4) AAA batteries (826 days /
2 or 3) = (413 days to 275 days)
(4) AA batteries (1,879 days /
2 or 3) = (935 days to 626 days)
(4) C batteries (5,510 days /
2 or 3) = (2,755 days to 1,836 days)
(4) D batteries (11,875 days /
2 or 3) = (5,937 days to 3,958 days)
Looking at the 9 V battery
calculations we can now estimate that a new 9V battery will power the X10 sensor
and X10 opto board for a period of 130 days (4.2 months) to 196 days (6.3
months). Looking at the other results for the X10 makes it obvious that larger
battery configurations will result in much longer battery life for the
sensor.....but is this true?
The last factor to consider when
choosing batteries is the internal drain of power all batteries experience over
time. Fresh batteries are all labeled with "use by" dates to let the consumer
know if the batteries are actually fresh. The need for the dated package should
inform you that even in non use a battery's power drains, and this is referred
to as internal drain. The older the battery grows the faster the internal drain
"leaks" the power from the battery.
In our application for the X10
sensor, the larger battery packs would be impractical because internal drain
would exceed the idle current draw of the sensor over time. It's recommended to
find a happy medium that is acceptable for your sensor. With the X10, a single 9
volt battery would be the best power source. 4 to 6 months of battery life would
utilize the battery's power for an acceptable time period, before internal drain
becomes sufficient . Larger battery packs for the X10 sensor, that would last
over a year, would waste battery power as the internal drain increases over
time. A chart with the idle current values and features of common sensors is
Batteries for the cameras are
handled a little differently then figuring out the expected time they will last.
The two trail camera types; 35mm vs. digital, utilize batteries in different
The 35mm camera is turned on when
the trail camera is activated and the camera is allowed to stay on. The
batteries function is to power the camera through a picture, charge the flash
capacitor (if needed), and advance the film after the picture is taken. During
idle, the camera batteries are still in use but at a low power drain; so in most
cases the original battery configuration supplied with the camera will suffice.
Practical expectations vary from 10 to 15 rolls of film during the warmer months
and 8 to 12 rolls of film during the cooler months, per battery pack. Extreme
cold or heat may affect the total rolls that can be processed per battery pack.
Since the 35mm camera can only shoot as many pictures as there is film, the
opportunity to change the camera's batteries is available with trips to change
the film. A recommendation is to also keep track of how long the batteries are
in use along with the total rolls processed by the battery pack.....the camera's
batteries are affected by internal drain, as explained above, and a set of
batteries a year old may only last 4 or 5 rolls of film.
The digital camera is also turned
on when the trail camera is activated and the camera is allowed to stay on. The
batteries function is to power the camera through a picture, charge the flash
capacitor (if needed), and record the picture to the digital camera's storage
medium. The recording of the picture to the storage medium is when the digital
camera uses a lot of battery power for an extended period, and thus they are
know to be inefficient. This inefficiency of power along with the cameras
ability to hold a greater number of pictures with a larger storage medium, makes
the camera's original battery configuration the limiting factor to the interval
between battery changes. The best "battery logic" to use for a digital trail
camera is to ask yourself how often will you be able to check the trail camera
after it's been deployed? If the digital trail camera is visited weekly or every
other week, the camera's original battery configuration should provide enough
power to last the duration. If the digital trail camera is intended for a long
duration of deployment, then auxiliary power is recommended with the appropriate
voltage outlined by the manufacturer. Through testing of the camera's original
battery configuration, an estimate of time can be achieved by comparing the mAh
of other size batteries used as auxiliary power. For example, if the digital
camera last one week on (4) AA alkaline batteries (2,707mAh) then (4) C alkaline
batteries (7,935mAh) should last close to 4 weeks before a change is required.
The calculated time interval between visits will help you decide if auxiliary
power is needed for your digital trail camera, and if additional space within
the enclosure is required.
The batteries are the "fuel" that
feed the trail camera and a large portion of the cost to run the homemade trail
cameras after they are assembled. A good understanding of the expected results
warrants the lengthy explanation and examples.

next consideration in building the homemade trail camera is the actual enclosure
or case that the camera, motion detector (or complete board) and battery packs
will be contained in.
The enclosure should be weather
tight to protect the electronics and camera from the elements. It should be
durable and strong enough to support the components, but not so "heavy duty"
that it ends up cumbersome to carry.
side note to this is a warning to trail cam users in "bear country". Bears are
extremely curious animals, therefore trail cameras in bear country need to be
protected with stronger enclosures that are able to take a beating or biting.
Metal or heavy plastic enclosures are recommended if a visit from "Yogi" is at
all possible. The film in 35mm trail cameras smells like food to a bear, and he
enjoys the challenge of opening the "little box that contains his diner". It's
also good to use the smallest possible enclosure that will hold all the
components without a lot of wasted space. Smaller enclosures are easier to
disguise and camouflage from potential theft, but keep in mind that a very small
requires a fair amount of planning to find adequate space for all the items.
Many of the internal components of the finished trail camera need to be
accessible, and a tight fit within the enclosure will lead to broken parts and
poor access to the components.
Common enclosures include ammo
storage boxes (usually found at surplus stores), empty metal first aid kits,
hard plastic or Lexan camping boxes and commercially made dry boxes. (usually
sold for precision equipment protection.)
Members of the
forum can answer your questions pertaining to the different enclosures and
recommend which one is best for a given combination of components. A list of
online stores that carry enclosures is also available on the
Homemade Trail Camera Links page under enclosures.

FILTERS, FRESNEL LENS
Filter? The selected enclosure
will be modified with a series of holes that align to the shutter and flash of
the camera, and the IR element of the chosen sensor. These holes need to be
covered to keep the trail camera enclosure weather tight. The shutter hole for
the camera is usually covered with standard 1/16" plate glass or a photographic
filter designed for lens protection. The filter may produce better quality
pictures by the fact that the glass within the filter is designed for
photographic use, but many homemade trail cam builders are more then satisfied
with the quality of pictures taken thru regular plate glass. It is recommended
to at least use new glass for the shutter hole, which shouldn't contain
scratches, instead of glass from an old picture frame or window. The end product
of the homemade trail camera is the pictures, so a good quality glass covering
for the shutter hole is a must.
Glass? The flash hole for the
camera can also be covered with standard 1/16" plate glass or even plexiglass.
The photographic quality is not as important for the flash hole covering, but
excessive scratches may hinder the range or effect of the flash. The glass for
the flash hole needs to be separate from the glass used for the shutter hole.
The possible effects of "flash bleed" will be evident on pictures in which one
piece of glass is used to cover both the shutter and flash holes within the
trail cam enclosure. It's better to eliminate the potential flash bleed problem
by using separate glass for the shutter and flash openings.
Another option for "weak flash" film or digital cameras is to use a "flash
enhancer" for the flash hole covering. The flash enhancer is a fresnel lens
pattern stamped into a clear polycarbonate film. The fresnel pattern is designed
to focus or enhance the flash by affecting the way the light travels thru the
lens. The resulting flash may seem more like a spot light then a flash field,
but the flash distance is usually increased and center focused pictures include
The same, or a different fresnel pattern is also used on the fresnel lens that
covers the IR sensor hole. The pattern is stamped into an IR transmissible
material and, when properly aligned, will focus the detection field directly
onto the IR element of the chosen sensor. Any motion within the detection
will trigger the sensor and
the camera connected to the sensor. Proper focal distance and centering of the
fresnel lens to the IR element of the sensor is a must, for any PIR sensor to
operate correctly. There are fresnel patterns designed to adjust the size or
shape of the detection field that is focused onto the IR element of the sensor,
therefore actual fresnel lenses may come in many shapes and sizes. The most
important aspects of any fresnel lens is the focal distance and focal length of
the lens itself. Online information on alternate fresnel patterns can be found
Fresnel Technologies , along with other PIR products listed on the
Homemade Trail Camera Links page of Hags House. Filters, glass circles,
flash enhancers and fresnel lenses are all available on the
Stock Parts Order Page
at Hag's House.

cell foam is used for many applications within the trail camera enclosure.
foam block matching the size and depth of the enclosure and cut to the outline
of the camera can be used to
hold the camera in place and aligned the camera to the 'window' openings of the
enclosure. The foam can also be used as a flash seal between the flash and
shutter within the enclosure. A certain amount of flash will be trapped within
the enclosure and a barrier is needed between the flash and the shutter of the
camera so the trapped flash does't wash out the picture.
Another innovative way to seal the space between the flash and shutter within
the trail camera enclosure is with a formed flash seal. Currently a formed flash
seal is available for the D370 or D380 digital cameras thru Arkansaselkhunter.

The finished trail camera may require an exterior switch to allow the user to
activate and deactivate the camera or sensor from outside the enclosure. This is
more common with
trail cameras then digital trail cameras, but it can be used for both. The
switch can complete the camera connection to the chosen sensor
switch the sensor to normal operating mode from test mode. The switch is used
when the trail camera enclosure is closed and it's located were the sensor will
not be triggered when changing the switch setting. Deactivating the camera
connection or switching the sensor out of normal operating mode will avoid
wasting valuable film when checking the trail camera . The common switch used is
a mini toggle switch with a weather protective rubber cover to seal the switch
from the elements. The use of exterior switches can be eliminated by using
certain complete boards listed above. Some boards can be programmed with preset
settings or PIC chips that return the camera to normal mode and would not
require the use of a exterior switch on the trail camera enclosure.
connector used between the camera and motion sensor can vary greatly.
camera modifications require either a two wire of three wire connector to
operate the camera functions. The chosen camera's modification and wiring will
lead you to how many wires and which type of connector to choose. Some cameras
have ample room for wires and/or jacks and others are very tight and require
connectors to wire within the camera.
An assortment of connector ideas can be
found in the
forum by noting
the different methods members have
used to connect their cameras to their sensors. Common
connectors are the 3 wire servo connector, 2.5mm stereo or 3.5mm mono plug and
jack, and a common phone plug and jack. The connector between the camera and
sensor is used repetitively when operating the trail camera, so choose a quality
connector that will last.

CAMOUFLAGE & DESICCANT
the finished trail camera in the field is aided by using some type of
on the outside surface of the trail camera enclosure. Camouflage spray paint,
camouflage tape or even 3D camouflage texturing have been used to help the
enclosure blend in with mother nature.
hide the trail camera and conceal the enclosure will help to prevent possible
theft and loss. Keeping a tight lip as to the location of the trail camera is
also essential. Many different camouflage applications can be noted by looking
at the member's finished trail cameras within the
Keeping the electronics and camera protected from moisture damage is done by
using some type of desiccant pack within the trail camera enclosure. Desiccant
absorbs moisture from the
air and a certain amount of desiccant is needed per the volume of air contained
within the enclosure. Just
because the enclosure is watertight does not mean moisture is not present within
the trapped air of
the enclosure. Outdoor temperature fluctuations will cause the trapped moisture
to condensate on the interior glass surfaces and electronics and over time, lead
to camera or sensor failure. Prevention of moisture by using desiccant is
strongly recommended. A common desiccant pack are the rechargeable ones used to
protect electronic instruments within their carrying cases.

TREE STRAPS & SECURITY
the trail camera to the tree is aided by a rope ratchet and rope or
of other attachment systems. The trail camera's weight needs to be supported and
held to the tree in a fixed position and stable. Bungee cords with U bolts or
eyelets are common, but can be restrictive when the bungee won't
around a big tree. E-Z web anchors are also common with a length of rubber robe
to hold the camera in place. Multiple systems to attach the finish trail camera
to a tree can be seen in the pictures posted in the
Adding some type of security system to your homemade trail camera can be
accomplished by assorted methods. Some enclosures come with padlock holes to
lock the enclosure and chain
the trail camera to a tree, or a cabinet lock can be installed to lock just the
enclosure. A cable lock passing thru an eyebolt or U bolt can be used to secure
the trail camera to the tree also. Master Lock's new Python Lock, designed as a
bicycle lock, can be used to attach the trail camera to the tree as well as
provide cable lock security. Breakable plastic cases can be outfitted with a
custom made cage to slip the enclosure into, and designed with a cable lock or
chain to secure the cage to the tree. A warning label on the outside of the
enclosure may aid in deterring an average passerby, but locking the trail camera
in some fashion is best. More security ideas can be found within the

Slave Flash? Adding
a slave flash to your homemade trail camera can improve night time
pictures from weak flash film or digital cameras. A popular combination is
combining a Slave Flash Controller board, designed by member Jon5ja, with a
Vivitar 2000 or Kalimar 175A slave flash. Instructions and information on the
