Monitor your garage, gate, driveway or doorway with the Seco-Larm Enforcer Polarized Reflective Beam Sensor (33'). This weatherproof sensor triggers an alarm in a connected security system when its infrared (IR) beam is broken. It also provides reliable detection of shiny objects (chrome bumper or other metallic material on a vehicle) that could be missed by a non-polarized sensor. The 3-1/4-inch round reflector can be installed discreetly on a wall or other flat surface. It provides a large sensing area for wide entryways, as well as easier alignment during installation.

NOTE: Requires a security system or alarm device to alert you when activated.
