Alarm Sensor Hidden Camera lets you record and capture videos covertly. It has a motion activation feature allows you to only capture video during the action and preventing you wasting hours sifting through footage of a silent empty area.
With its remote control operation, you can manually control the DVR from up to 30 feet away. This way, you don't need to draw extra attention to the device by walking right up to it.
It also has an auto overwrite feature wherein if the SD card becomes full, older files are automatically replaced by newer ones, thus removing the need for manually deleting innocuous footage.
