2.6 Advantages of Prep Sensors
In general, to save battery power, an Infer-Red camera is in “sleep” mode,
with only the PIR sensor working. When game is detected by the PIR sensor,
the camera is powered on and starts shooting pictures. The time period from
being activated to starting firing is called trigger time. The trigger time varies
among different scouting camera brands in the market, generally from 1 to 5
plus seconds. Our Ltl Acorn scouting camera has an impressive 0.8 second
trigger time. However, when game passes across very quickly, the picture
may only capture the rear part of the body, and possibly nothing at all.
With the unique side prep PIR sensors design, our Ltl Acorn solves this issue.
The combination of the two side prep sensors and the main sensor comes
up with a 100 to 120° angle of induction, a very wide scope far outweighing
the 50 ° angle of the camera lens. When game first crosses the PIR area of
the prep sensor, the camera is activated and ready to shoot after 1 second. If
the game continually enters into the PIR area of the main sensor, the camera
takes pictures immediately, therefore catching the whole body of the game.
This split-second process could be as short as 0.2 second.
In the case the game browses only in the PIR area of the prep sensors, to
avoid the camera being powered on constantly, the system is designed to
work in the following way: If the game does not enter the PIR area of the
main sensor and therefore not trigger the main sensor, the camera will power
off after 3 seconds. If the trigger events consecutively happened twice only in
the PIR area of the prep sensors, the camera will not be activated by the
side prep sensors, but only by the main sensor. So later on when the game
enters the PIR area of the main sensor eventually, since it is not in fast
movement, the picture will by all means capture the whole body of the game
based on our standard 0.8 second response time.
