The perfect covert video recorder that is perfect for your yard. This unit looks like a common rock and is waterproof and reliable in all weather conditions. The battery provides up to a full year of standby power with over 20 hours of video recording on a single charge. The rock is very small and easy to hide. Select the video recording resolution that’s right for you from 320 x 240 up to 1280 x 960 High Definition. The DVR includes a miniature PIR motion detection sensor. The DVR “sleeps” until motion is detected. Then it will record every detail until motion stops then return to sleep mode. Replay recorded video footage on either TV or PC, or MAC directly from the SD card.
