Glossary
PIR—Passive Infrared Sensor. Senses motion like typical security motion detector. Requires infrared energy (heat) in
addition to motion to trip sensor to assure detection of live animals.
Event—Any time that the PIR senses motion it counts it as an event. Events are recorded to the SD card in a text file.
Events are recorded continuously during operation.
Image—A digital picture recorded on the SD Card when motion is sensed. Images are taken at the desired delay between
images.
Image Delay—Time elapsed between photos while events are sensed and recorded. This is fixed at 30 second intervals
in the Trail Sentry.
IR Flash—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.
Standard Flash—Xenon Flash used for low light photography. Automatically fires if required.
SD Card—Memory card used to store images and events. Compatible with up to 1GB capacity SD card.
Battery Life—Time that camera will function in the field. Dependent on temperature, number of images and number of
flashes during that time.
Setup—Using the display menu and buttons to set the date/time, still photo or movies, and password.
Security (2 methods)—One of the most important requirements of any trail camera. The Trail Sentry has levels—
padlock tab and software password.
Trigger Speed—Time delay between a subject passing in front of PIR sensor and the image capture of that subject. All
Bushnell Trail Cameras have a trigger speed of less than one second.
