DCPA-4K-PLUS Dakota Alert Driveway Alert System with Magnetic Driveway Sensor


This is a probe-based (Magnetometer) driveway alarm kit.  The probe-based sensor is triggered when heavy metallic objects such as cars, trucks, etc., pass through the monitored zone.  The sensor then transmits a wireless signal, up to 5,000 ft. away to the receiver.  The receiver will then play a selected chime sound.  You can add transmitters and receivers to expand your system.

I Need a Driveway Alert System with a Hidden Driveway Car Sensor

We would like to introduce you to the Dakota Alert Driveway Alarm, the DCPA-4K-PLUS. Many driveway alert systems feature a passive-infrared sensor that is triggered when a combination of heat and movement is detected within the monitored zone of the sensor.  While this is a great feature if you want notifications for people and cars, if you live in a wooded area or an area with many animals, or do not want a notification if people pass through the zone, a magnetometer-based probe sensor (magnetic probe driveway alarm) is a great choice and works well as a farm driveway alarm, gate alarm, or driveway car sensor. The DCPA-4K-PLUS Dakota Alert Wireless Driveway Alert Alarm Kit with Enhanced Receiver is the one that stands out above all others.

How Does this Driveway Monitoring Kit Work?

This driveway monitoring kit will detect vehicles only that pass through the monitored zone and send a wireless signal up 5,000 ft. away to the plug-in receiver.  The sensor features a magnetometer probe you bury parallel to the driveway.  This creates a detection zone of 12′-13′.  50’ft of burial cable connects to the transmitter, which allows you to hide the transmitter and mount it to a post or nearby tree.  When an automobile passes through the driveway detector zone, the sensor triggers an alert and sends a wireless signal to the receiver. Additional burial cable lengths are available for an additional cost–please call or email for additional information.

Because the probe is buried and the transmitter may be mounted to a tree or other post, this becomes a great hidden driveway alarm.

How the Dakota Driveway Sensor Probe Works:

When a car passes through this zone, the transmitter will send a wireless signal up to 5,000 ft. to the receiver.  This is a line-of-sight distance.  Environmental factors such as terrain, metal, and building materials will diminish the signal, but with a range of up to a full mile, this tends to work for most customers.

  • Magnetometer probe is triggered by metallic objects.
  • Sensor will detect vehicles within 12′-13′ of the buried probe.
  • 50 feet of burial cable connects the probe to the black transmitter box.
  • Powered by 4 x CR123A high-powered, long-lasting lithium batteries.
  • Sensor/transmitter is outdoor rated.
  • Operating temperature range from -30F to 120F.
  • One year manufacturer’s warranty on products.

How the Dakota 4000 Series Receiver Works:

The receiver featured in this kit will play 1 of 16 melodies when triggered.  This receiver is capable of working with up to 12 different transmitters/sensors at a time and the available melodies enable you to assign a different sound to each transmitter/sensor allowing you to distinguish which transmitter triggered the receiver.

The receiver plugs into a standard wall outlet and will sit on a flat surface or may be mounted on the wall.  The receiver features 2 x C-Form relays enabling you to integrate it with other systems, such as security systems, guard gates, etc.  In addition, the receiver features 1 x 12V DC output allowing you to connect devices such as a mini-strobe/siren, strobe lights, sirens, fire alarm bells, etc.

Driveway Monitor Probe Kit Receiver Features:

  • Each receiver will work with up to 12 transmitters/sensors.
  • Add as many add-on receivers as you want.  This allows you to spread receivers throughout your location to better distribute the sound.
  • The receiver has volume control and will play one of sixteen different melodies.
  • Receiver plugs into a standard wall outlet.
  • Receiver is indoor rated only.
  • Range from transmitter to receiver is up t0 5000 ft.  The actual range will vary depending on the specific environment.
  • Receiver features 2 x C-Form relays and 1 x 12V DC output.

Uses for the DCPA-4K-PLUS

In this simplest form, this products is a great driveway alert system that will provide years of security for your home (or office) by notifying you when an automobile enters your driveway. If you want a farm driveway alarm, this is a great option because of the long range provided. With a range of up to 5,000 feet from the magnetic driveway sensor to the receiver, it’s a great wireless driveway alert alarm kit. For many farm owners they cannot see the entrance to their property. Buy using this kit, owners will receiver an immediate alert.

Another potential option is to use the kit for gate alarms driveway security. When a car or truck passes through a driveway gate, the probe will trigger and transmit a chime signal to the receiver.

Great product !

Bought this Dakota alarm to replace a 20+ year old Dakota alarm. Really like the choice of sounds and the long range of the detector. Do wish it had a simple on/off switch on the receiver. Definitely recommend Dakota alarms.

Excellent Driveway Alarm

I installed this driveway alarm a few days ago and I must say that the installation went much easier than I had planned. The pairing of the transmitter to receiver was simple and seamless. High quality product, no more false alarms from animals, etc. I feel this is the best driveway alarm I have ever used and the range between transmitter and receiver is amazing.

Best sensor, best range

My driveway is 3000 ft long through a forest. I put the sensor about two thousand feet from the house. I have two receivers one at the house and one at the shop. It triggers reliably every time. I have used their wired products for many years and have never had a problem. The range is incredible if I had line of sight I'm sure it would go a mile but to go a couple thousand feet through heavily wooded is amazing.

B.R. (Hickory, US)
