Looks very similar to an alarm PIR or motion detector when installed. With an built in motion detector and pinhole color camera it will take snap shot photos when human movement is detected. Photos are time, date and title stamped. Use the computer software to configure the unit for different situations. Uses a removable memory card to store the pictures and includes a USB reader. The remote control is for wireless on/off and snapshot control. External motion detected output for lights. Can be battery powered for weeks.
