The sensitivity of the motion sensor is fully adjustable, allowing pet owners to tweak the unit for best performance without false positives. The unit has a range of 30 feet and a sensor angle view of 90° (horizontal). For best performance, mount the unit flush against a wall at a height of 6-8 feet. It is not necessary to point the unit downward. An exposed side-mounted button allows for easy unit testing and setup and the default 10 minute setup cycle provides users and installers plenty of time to configure the unit. Use this feature with Vera to trigger an email alert if the battery drops below a certain (user definable) point.
