Optex Wireless TD-20U - Description
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.
