Dakota Alert DCMT-4000 Wireless Driveway Alarm

The Dakota Alert DCMT-4000 is a battery-powered outdoor PIR motion transmitter that detects people and vehicles up to 100 feet away and sends alerts to receivers as far as one mile.

Designed for property owners who need simple, reliable perimeter notifications, the DCMT-4000 combines passive infrared motion detection with long-range radio transmission and easy wireless pairing. The unit runs on a single 9-volt battery (not included), mounts outdoors, and pairs with any 4000 Series Dakota Alert receiver — letting you add multiple sensors to cover driveways, yards, outbuildings, and long approaches without running wires.

How far will the DCMT-4000 detect motion and reach the receiver?

The sensor's detection zone extends roughly 100 feet for people or vehicles under typical outdoor conditions. When the sensor triggers, its radio signal can reach a compatible receiver up to one mile away in open terrain; actual range depends on terrain, obstructions, and radio interference.

• Motion detection: up to 100 feet for people or vehicles
• Radio transmission: up to 1 mile line-of-sight
• Range varies with hills, trees, buildings, and RF noise

How difficult is installation and setup?

Setup is intentionally straightforward: mount the transmitter, insert a 9V battery, and use Dakota Alert's code-learning method to pair with a 4000 Series receiver. No wiring or solar panels are required, so a functional perimeter alarm can be in place within minutes.

• Surface-mountable housing for quick outdoor installation
• Simple code-learn pairing with compatible receivers
• Supports up to 16 sensors per receiver for clustered coverage

What power and maintenance should I expect?

The DCMT-4000 runs on one standard 9-volt battery and is engineered for long life; under normal conditions a single battery can provide more than a year of operation. Because it’s battery-powered, maintenance consists mainly of periodic battery replacement and occasional cleaning of the sensor lens.

• Power: one 9V battery (not included)
• Battery life: typically over one year depending on activity levels
• Low maintenance: lens cleaning and annual battery check recommended

Can I expand the system or use it for different locations?

Yes — the DCMT-4000 is made to be part of a modular system. You can link multiple DCMT-4000 transmitters to a single receiver, deploy receivers in multiple buildings, or mix with other Dakota Alert 4000 Series components to suit larger properties and varied monitoring points.

• Pairs with any Dakota Alert 4000 Series receiver
• Up to 16 sensors can be assigned to one receiver
• Unlimited receivers can monitor a single sensor for multi-location alerts

Who is this for? The DCMT-4000 fits homeowners, farmers, cabin owners, small businesses, and property managers who need a no-fuss, wireless alert for driveways, gates, yards, sheds, or long approaches. If you want an outdoor motion sensor that avoids wiring, delivers long radio range, and integrates with Dakota Alert's trusted 4000 Series receivers, this transmitter provides a practical, field-proven solution backed by a South Dakota company with decades in the wireless driveway alarm market.
