The IMV 200/601/701 consists of a digital camera, a passive infrared motion detector, and S 2 VIEW spread spectrum, Videofied interactive, encrypted wireless circuitry for secure two-way communications with the control panel. The camera consists of a CMOS color sensor and an 110°, wide angle lens. Two infrared LEDs provide a night illumination distance of approximately 23 feet/7 meters. For motion or movement detection, a fresnel lens inside the cover captures a up to 40-foot wide, 90° angle passive infrared pattern. The base allows for flat wall or corner mounting. A dual tamper function provides for both wall and cover tamper detection . The camera is typically installed to cover rooms, hallways, stairwells, and other similar areas where detection coverage is needed. When the alarm system is armed and the motion detector senses heat motion, the detector transmits a signal and activates the camera, which captures up to a 10-second digital video segment. The control panel receives the signal and responds according to system configuration/programming. The alarm and video segment are reported via the control panel to the central monitoring station. The detector is powered by three lithium batteries that can last up to four years or more, depending on the amount of detector activity.
