Dakota Alert™ Add-on Mile Motion Sensor Transmitter

You can add up to three of these DCMT-4000 transmitters to the Dakota 1 Mile Wireless Alert Kit DCMA-4000, allowing you to monitor up to four areas using a single receiver. It uses a passive infrared (PIR) detector to detect people, vehicles or large animals passing by a monitored location out to approximately 50 feet. When the transmitter detects the object, it sends a signal to the receiver up to a mile away, triggering an alert tone. This motion activated sensor/transmitter projects a cone-shaped beam of coverage across the monitored area of approximately 30 feet, 50 feet, or 80 feet wide, depending on the setting you select. If using multiple transmitters, you can assign a different alert sound to each area to distinguish which zone has triggered the alert. Installation is quick and simple and can be done by virtually anyone. The motion detecting sensor/transmitter operates on one 9-volt battery (not included, see Accessories).
