The Image Sensor is a motion sensor with a built-in still camera that can be placed anywhere in the home for easy, wireless, affordable surveillance. If the alarm is triggered the Image Sensor will automatically take pictures and send them to your panel and your mobile device. You can also manually "peek-in" either right now or the next time the Image Sensor detects motion and a photo will be sent automatically to your phone via text or email.
