HALT-2 Field Camera
The HALT-2 uses a digital Field camera as its host and will operate as designed minus the Passive Infrared (PIR) trigger. HALT-2 does not require an external battery or controller. If you are familiar with using PIR camera traps, remember the HALT-2 camera trap system is different. No False Triggers from wind or rain! You will be saving space on your memory card which allows you to think differently about collecting data. Please get used to your HALT-2 camera trap system before installing out in the field for first time. You may discover adding a 6 second video after a single picture gives you better data. Be aware, the field of view for pictures (.jpg) are different than for video (.avi). Play around with your camera to discover new ways to collect data.
HALT-2 improvements:
1) No External Battery
3) No External Controller
4) Threshold is water tight
5) Bug tubes are non-permeable. Bugs cannot climb into small tubes.
6) If beam becomes blocked, camera will default to an interval mode. This improvement allows for time and effort calculations, rather than lost data. If beam clears, trigger will activate, giving time of clearance before resuming.
7) Light to Moderate rain will not produce false triggers.
HALT-2 Threshold
HALT-2 offers two Threshold lengths:
14.5" in length: minimum 46 cm (18.0") focus distance: Cable extends 3ft.
18" in length: minimum 60 cm (23.5") focus distance: Cable extends 4ft.
The crest is 1.250" high. Ramps are 2" wide on both sides. The optical beam is elevated 1cm above crest. It is recommended that technicians exchange SD memory and inspect threshold every 7-10 days to ensure no objects (leaves, sticks, vegetation) are blocking the optical beam. Internal batteries can last 3-4 months depending on traffic of species.
