Use this Z-Wave motion detector to detect motion in any room. The unit is totally wireless and runs on 4 AAA batteries (included). The unit can control up to 5 Z-Wave devices directly, or it can be programmed to send commands directly to HomeSeer or any Z-Wave Controller where more complex events can be triggered. The unit includes a swivel mounting bracket for easy aiming. The lens is adjustable in two positions. Position 1 is wide angle and has a max range of 39 feet. Position two is long range, about 46 feet. The unit will only send a motion command once, when it detects motion. It will then send one "No Motion" command after a programmable period of time that it does not detect any motion (default is 2 minutes). To program the "No Motion" time, a ZTH200 remote is required.
