ABOUT THE PIR SENSOR
The sensor that triggers the trail camera is Passive Infra Red, or PIR. Infrared energy is essentially heat energy.
The PIR detector operates by sensing a change in the infrared level in its detection zone. This zone is a cone in the
center 10 degrees of the camera’s field of view. The camera establishes an average long-term infrared level. When
this level increased suddenly the PIR detector signals the camera to record a picture and/or an event. Because of
this effect, the PIR detector will be more sensitive at night, when the average temperature is lower.
You can use the red LED indicator on the front of the camera to confirm the detection zone.When PIR is sensed,
this “PIR detected” indicator will light. The camera’s field of view is a 45 degree cone, centered on the PIR detection
zone.
MOON PHASE STAMP
All new Trail Sentry models have a “moon phase” stamp feature. This links the current date (as set by the user in
the setup procedure) to the phase of the moon on that date (this data is stored on an internal memory chip), and
imprints a icon on your photo which represents the moon phase when the photo was taken.
The moon phase icon
will appear on your photos in the lower left, next to the Bushnell logo.
Some hunters will find this to be a useful
reference, as it can help determine if particular animals are inactive at night when a full or nearly full moon is
present, causing them to be more visible to predators. Or, if some of your night photos seem to have a darker or
lighter background (beyond the range of the LED lamps or flash), you can see if that was related to how bright the
moon was at the time.
The icons for the various phases of the moon are shown below:
