If you only need to record short span of activity in a given area you may want to consider the motion activated hidden camera. Motioned activated hidden cameras have built in sensors that use passive infrared technology to determine when there is movement in a given area and switch into record mode to record that activity. So you are only recording when there is action.

Motion activated recording helps you avoid the long hours of dead video and lets you quickly access recordings of any activity in the area you are monitoring.

The motion activated cameras also save you money because you do not have to also purchase the digital video recorder. DVR cameras have the ability to record and store video files on an SD card you can remove from the unit for playback on your computer.

Motion activated cameras can work from battery power or plugged directly into a wall of clip for continuous power. Selecting the motion activated spy camera that looks natural when plugged into a wall is your best bet because the device can access continuous power rather than the battery which needs to be recharged or replaced every eight to 24 hours.

Hidden surveillance cameras with built-in motion detection sensors only record when there is action in the area under surveillance... great for remote locations where wires are not an option and wireless does not transmit far enough. Motion activated cameras save you time. No more scrolling through hours of "dead"" surveillance video. Low power consumption means batteries last a long time on a single charge.
