Create a secure perimeter along your driveway, front door, side gate and more with the Seco-Larm Enforcer Retro-Reflective Photoelectric Beam Sensor. The kit creates an invisible infrared beam and alerts you when the beam is broken by sounding your alarm (sold separately). The sensor is constructed in a rugged, weatherproof enclosure for maximum durability wherever you install it.
This kit can be used for a variety of applications. Use it as an alarm to protect yourself from home intruders. Mount it in front of a driveway so you know when a car pulls up. You can even use the sensor as a parking indicator in your garage to help you park in the right spot.
