The VS-14 Sentinel from Intelepresence is a stand alone remotely triggered video surveillance system. Housed in a Pelican 1400, a 12-volt DC rechargeable battery provides enough power to provide a 30-day stand-by duration. Therefore, the Sentinel can be left in the field virtually unattended to gather evidentiary footage all on its own. When a person or vehicle approaches the Sentinel, up to several hundred feet away, various types of wireless triggers will wake up the unit and it begins to record video. Duration of each recorded event is set by the user and can be changed between one minute and one hour, for up to five hours of footage. A Sony Z-Box 2 records a time/date stamp on the video.
