This driveway sensor is backwards compatible meaning it will work with all of the original Optex Wireless 1000 components as well as the new Optex Wireless 2000 components. The built-in infrared sensor and wireless transmitter are capable of sending an alarm signal up to 2000 feet back to either Optex RC-10 or the RC-20 receivers which will then notify you through a pleasant chime sound. The infrared sensor has two settings for the infrared sensor: fan and long range beam. The fan setting is perfect for door and entrance ways or even as a motion sensor mounted the corned of a room. The beam setting will monitor up to 50 feet in front of the sensor making it ideal for wide driveways, parking lots or even as a perimeter sensor for your property.
