The TD-20 Sensor/Transmitter is a PIR detector which will detect both people and vehicles entering it's detection path. This weatherproof wireless indoor/outdoor sensor transmitter mounts easily wherever you need to know of people or cars arriving or leaving, and sends a signal back to the Optex RC-20 Receiver (up to 2000') to alert you of visitors. It includes two detection patterns: fan (~17' semi-circle) or long range (at ~50' away from transmitter invisible beam size is 6' x 9' rectangular). The TD-20 is easily mounted behind a tree with its unique mounting capability. This TD-20 sensor/transmitter works with the RC20 (item 80-506) wireless receiver.
