Video Camera Outside Animal Spy Cam Camouflaged Battery Operated 6 MONTHS: When you install 8-AA lithium energizers you can achieve 6 months of use. VIDEO CAMERA: The video camera records .AVI videos at 640x480 resolution on its standard setting but can also cut that in half, to 320x240, to save memory. On that setting, youll be able to stretch your MicroSDHC twice as far. NIGHT-VISION: The AcornTrail also gets great shots at night, with 26 infared 940nm LED lights allowing it to see up to 65 feet in front of the lens. The infared lights are beyond human and animal vision, so they wont alert the subjects. HEAT SENSOR: The AcornTrail can automatically shoot video or still photos when the heat sensor is triggered. There are 3 settings for sensitivity: Low, Medium, and High. If youre looking for small, quick creatures, try the high setting. To reduce the sensitivity for larger animals, try Medium or Low.
