A commercial camera trap unit has a passive infrared (PIR) sensor for motion detection.
Generation 1A: Initial prototype model based on Arduino and using a serial camera.
Generation 1B: A refined version of 1A with a custom-designed board and a serial camera.
Generation 1C: Battery operated version based on Raspberry Pi (Linux computer) and a 5M pixel resoultion camera.
Generation 1D: Power over Ethernet (PoE) operated version based on Raspberry Pi (Linux computer) and a 5M pixel resoultion camera.
WiSE 2: Solar powered digital platform with IP camera, satellite Internet, solar panels and wirless sensor network.
Pole mounted sensors for determining the best height/tilt of sensors for detection.
