Seems every hobby comes with it's own lingo and I've been asked thru email "what does this word actually mean?"
So I threw some definitions together of how I interpret the "slang terms" we read here and hopefully this helps some of the new guys to catch on faster.....
Hopefully the great definer (Archilochus) will read this and critique my translations. The guy just has a way of explaining things.....
Camera Related Terms:
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.
Shutter Assembly? – 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.
Flash Bleed? – The “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.
Always On? – 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 PIC chip.
On-Off? – 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.
Slave Flash? – 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.
PIC Chip Related Terms:
PIC Chip? - Programmable Integrated Circuit Chip (the IC Chip itself) used to control the functions of the camera along with various features listed below.
Initial Delay? – 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 startup.
Standby Mode? – 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.
Walk Test Mode? – 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.
Delay Mode? – 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.
Sleep Mode? – 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:
IR Sensor? – 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 sensor itself.
Fresnel Lens? – 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.
PIR Sequencing? – 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.
