Wireless Motion Sensor Transmitter
The Wireless Motion Sensor Transmitter (DCMT-4000) from Dakota Alert is a proven, field-hardened PIR motion detector designed to detect people or vehicles and transmit alerts wirelessly to a compatible receiver.
MAXSUR integrates this sensor as part of event-driven surveillance architectures, where motion detection is used to trigger alerts, conserve power, and activate downstream systems only when activity is present.
Where It Fits
This sensor is a strong component for long-duration, power-conscious deployments—especially in rural or perimeter environments.
- Rural and perimeter surveillance
- Long-duration covert deployments
- Driveway, access road, and approach monitoring
- Power-constrained or low-signature operations
Key Capabilities
- Detects people or vehicles entering a monitored area
- Adjustable detection range (up to ~100 ft)
- Configurable reset time to control alert frequency
- Wireless transmission to compatible Dakota Alert receivers
- Supports multiple transmitters per receiver (up to 16)
- Includes plate mount (outdoor) and swivel mount (indoor)
Installation Notes
For maximum wireless range, the manufacturer recommends mounting on a wooden post or tree and avoiding steel posts that may interfere with signal performance.
- Mount ~3–4 feet off the ground
- Place ~20 feet from the side of a drive for driveway/approach monitoring
- Keep the unit immobile to reduce false activations
Uses a 9V alkaline battery (not included).

*Actual wireless range varies with terrain, vegetation, structures, and mounting conditions. Specs summarized from the Dakota Alert DCMT-4000 user guide. :contentReference[oaicite:0]{index=0}
When paired with the corresponding receiver (sold separately), the receiver’s dry contact outputs can be used to trigger alerts on other devices, activate remotely located infrared illuminators, switch relays/digital inputs, or even wake surveillance systems from deep sleep to conserve power.
