Buying notes
Is this the right fit?
- Good fit when
- Use this when you need a complete setup with the sensor and receiver included, instead of trying to match separate parts.
- Look at another option when
- Look at a separate transmitter or receiver when you are only replacing one part of a system that already works.
- Range reality
- 5,000 ft is the published open-air range. Real-world range is lower when the signal crosses walls, metal, masonry, vehicles, shelving, or dense trees.
- Setup note
- Place the sensor where the event happens, then place the receiver where the alert needs to be heard or seen. Test the signal before final mounting.
For more significant properties, the DCMA-4000 Dakota Driveway Alarm is a great long-range driveway monitor. It’s a complete driveway monitoring system that’s reliable, high-powered, and budget-friendly based on its performance range. Like most wireless kits, it works when the transmitter/sensor detects movement and sends a wireless signal to the plug-in receiver.
The driveway sensor/transmitter emits an invisible laser beam, creating a detection zone of up to 50′. When the combination of heat and movement enters this detection created by the driveway monitoring zone, your chime/receiver will sound, alerting you that movement has been detected.
This product is similar to the ERA-DSDCR driveway alarm kit by Safeguard Supply. The ERA-DSDCR features 4 x 12V DC outputs and a C-Form relay to add sirens, strobes, and other accessories, whereas this driveway monitoring system, the DMCA-4000 by Dakota Alert, does not.
Reasons to Choose the DCMA-4000 Driveway Monitor:
- A range of 5,000 feet (transmitter to receiver) is ideal for large properties or areas where environmental factors interfere with shorter-range alarm systems.
- Small transmitter blends seamlessly into the environment to avoid detection.
- Expandable product – add more receivers, transmitters, or other helpful accessories
This Dakota driveway alarm, the DCMA-4000, ships with two components, the DCMT-4000 and the DCR-4000, which are a sensor/transmitter and a receiver/speaker, respectively. If you have more than one drive way, or area, you would like to monitor; you can expand the system with additional driveway monitoring alert transmitters. You can also add more receivers to the system.
The Dakota driveway sensor is a small, compact device powered by a 9-volt battery. To monitor your driveway – or any area – mount the outdoor driveway motion sensor perpendicular to the area you want to monitor. The transmitter has a detection zone of roughly 50 feet, and when it detects movement, it transmits a wireless signal to the plugin receiver/speaker.
For example, if you want to monitor the driveway, simply mount the sensor next to the driveway with the beam shooting across it. At our offices, we use the transmitter to notify us when a delivery truck approaches the loading door.
- The sensor detection zone emitted from the sensor is approximately 50 feet. The beam comes out small and tends to fan out the further you move from the sensor.
- The sensor will transmit a wireless signal up to 5,000 ft (depending on environmental factors). This is the distance from the transmitter to the receiver.
- The wireless sensor is powered by a 9-volt battery. In normal conditions, the battery life is approximately 1-1/2 years.
- The receiver plugs into a standard wall outlet.
- Operates with all Dakota 4000 products.
- The receiver has a volume control.
*Please note the video below demonstrates the DCMA-2500 by Dakota Alert, which has been discontinued. The upgraded model is the DCMA-400 which increases the driveway monitor alarm distance by up to 5,000 ft. from the driveway sensor to the driveway chime receiver.

Works great, 👍
★★★★★Mike R.Oct 29, 2025
Works great! Also love that the sensor is 9 V battery powered...no wiring needed! We have two driveways that are 75' apart. We can never hear cars pulling in. Placed the sensor on the outside of one drive, so that it is facing across both drives. Set the distance jumper in the sensor to the "100 ft" setting and it triggers the alarm, which is about 150 ft away inside the house, from either drive. Perfect! Am ordering more receivers so as to also have one in the work shop and one on the back pool deck.

We've had infrared alarms for over a decade, and these are the best yet. We learned to listen for the timing between sensors in order to verify a vehicle is coming , and where it is on our driveway. Now, with different sounds from each sensor being programmable, we know exactly where it is, and if it is just a deer or fox.

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.
★★★★★Kenneth W.Oct 9, 2021
Very easy to install and has better Alarm than the old one. Very pleased and would highly recommend it.
★★★★★Ashleigh S.Jul 26, 2021
We live up a hill surrounded by many trees. I am so impressed that this sits at the end of our long drive and still reaches into our home! GREAT PRODUCT!
★★★★★Duane W.Apr 13, 2021
Great service. Alarm that doesn't give false alarms.
★★★☆☆ChuckOct 10, 2020
Our requirement is for a night time security device, (8pm - 6am). We have employees that start arriving after 6am and to have the alarm going off because of employees is unacceptable. We can't use the monitor!
★★★★★Kurt L.Sep 8, 2020
I have the one sensor located a bit close to the driveway and at times it doesn't trip. More so when vehicles are leaving it seems to be working when they pull in. Sensor is hiding great where it is not really wanting to call attention to it by moving further from the driveway.
★★★★★Kristin P.Dec 2, 2019
Works great
★★★★★marilyn W.Jul 6, 2019
This has been a great set up for us knowing we can add more security if we need to.
★★★★★PaulJul 17, 2017
We have 2 driveways and purchased 2 transmitters , 1 for each driveway. They work very nice with different chimes for each one. this is our 2nd set , the first one lasted about 8 years and was not dependable any more. these are much better and work great.
★★★★★CindyRobertsJul 7, 2015
We installed the Driveway alarm on our driveway and it does exactly as described. We chose the chime setting which chimes twice when someone enters the driveway. Very handy for us as we have a long driveway and not good site view from inside the house.
★★★★★ButchJun 2, 2015
This product exceeded my expectations. It was as advertised.
★★★☆☆DeuceciApr 20, 2015
I ordered the DCMA-2500 Long Range Wireless Driveway Alarm system and recevied it within days and as advertised. The transmitter was easy to install and all works great.

Questions & Answers
Answers from our team for DCMA-4000 Dakota Alert Driveway Monitor.
Can you shield it from falling leaves?
Good morning. Falling leaves will not activate the DCMA-4000's outdoor sensor. The sensor is a PIR transmitter that is only activated by heat and motion combined. Thank you, Customer Support Team 1800Doorbell
Answered for Connie S.
Do you have to have special equipment to install it outside on a gate? If so what do you need to install it?
Hello, There are a couple of different ways you can mount the transmitter/sensor you can see here: https://www.1800doorbell.com/wp-content/uploads/pdf/DCMT-4000-User-Manual.pdf
