The Honeywell Home Indoor MotionViewer is a combination motion sensor and video camera in one unit that expands your Honeywell Home alarm system. Intelligent motion detection ignores false alarms like blowing curtains or moving ceiling fans. You'll get a notification and see the video when a real person or intruder triggers the sensor. The built in battery lasts up to 2 years with typical use so you don't have to worry about frequent battery changes. Compatible with the Honeywell Smart Home ZWave Security System.
