• Weatherproof
• (PIR) Passive Infrared Beam
• Detects Up to 80 Feet
• Sends Radio Signals Up to 600 Feet Away

The transmitter operates on one 9-volt battery and is easily mounted on a tree or post near the drive. The transmitter uses a passive infrared (PIR) beam to detect people or vehicles to a distance of up to 80 feet, then sends a radio signal back to the WR-3000 receiver up to 600 feet away.

The transmitter is weather proof and meant for exterior locations. Up to four zones can be monitored with additional transmitters. The transmitters can be programmed so they will each sound a different tone at the receiver.
