This covert security system from DEFENDER lets you monitor what is important to you while remaining discreet. Disguised as a Magnasonic alarm clock, the unit can capture over 40 days of high quality video without anyone knowing. This easy to use, covert DVR system is ideal for monitoring your office, nanny, employees and valuables. Just place the alarm clock on any desk or cabinet and you will be able to record video completely undetected. A built-in motion sensor can help conserve SD card space by only triggering a recording when movement is detected. So feel free to supervise your business or home discreetly with the ST300-SD and always be aware of what’s happening, even when you are not there.
