Tech Talk Trail Cameras
Like the standard film camera, digital imaging technology uses a lens to focus the image on a focal plane. While the film camera relies on a film to capture the image, the digital relies on a sensor. As light strikes the array of picture elements (pixels), which make up the sensor, it is converted to a current that is then passed onto a digital or A-D converter. From the A-D converter, algorithms are then applied to the data, converting it to a digitized image file.

PIR (Passive Infrared)
Security Sensor device that senses motion like a typical motion detector. Requires Infrared Energy and Motion to trip sensor.
A digital picture recorded on the SD Card when motion is sensed. Images are taken at the desired delay between images.
Delay between images taken by the camera. This is set by the user, based on wildlife activity in area.
LED Night Vision flash. Sends a burst of Infrared Energy which is invisible to the human eye. Especially useful for night photos when a visible flash is undesirable such as in high pressure hunting areas.
Time that the camera will function in the field. Dependent on temperature, number of images and number of flashes during that time.
