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
- 5000 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.

I Need a Driveway Alert System with a Hidden Driveway Car Sensor
Introducing the DCPA-4K-PLUS Dakota Alert Driveway Alarm – a driveway alarm that uses a magnetic sensor to detect vehicles entering or leaving your driveway. Unlike traditional motion sensors, this system relies on a buried magnetic probe that creates a detection zone parallel to your driveway. When a car or truck passes through this zone, the transmitter sends a wireless signal up to 5,000 feet to the receiver, triggering an alert.
How the Magnetic Probe Sensor Works
The heart of the DCPA-4K-PLUS is its magnetometer probe, designed to detect metallic objects up to about 10 ft away. This probe is buried under the driveway or parallel to your driveway, creating an invisible detection zone that spans the width of your driveway. When a vehicle passes through this zone, the probe senses the change in the magnetic field, triggering the transmitter to send a wireless signal to the receiver.
The transmitter is powered by three long-lasting CR123A lithium batteries (included), ensuring reliable operation in extreme temperatures ranging from -30°F to 120°F. It transmits a signal to the included receiver, which can be placed anywhere in your home or office up to a line-of-sight distance of 5,000 feet. The number of receivers you can add to your system is unlimited.
Customizable Alerts on the RE-4K PLUS Receiver
The receiver is a versatile unit that can work with up to 16 different transmitters or sensors, each with its unique melody. This feature allows you to assign different sounds for each driveway or approach to your property, enabling you to identify which transmitter was triggered easily. The receiver plugs into a standard wall outlet and can be placed on a flat surface or mounted on the wall.
Integrate the Dakota Alert Receiver with Existing Systems
The DCPA-4K-PLUS receiver is designed to seamlessly integrate with existing security systems, guard gates, or other automation devices. It features two C-Form relays and a 12V DC output, allowing you to connect additional devices such as strobe lights, sirens, or fire alarm bells.
Easy Installation and Maintenance of the DCPA-4K-PLUS
Thanks to its straightforward design and included accessories, installing the DCPA-4K-PLUS is simple. The magnetic probe can be buried under or parallel to the driveway, from 3”-12” deep. It is connected to the transmitter via 50 feet of burial cable, allowing you to conceal the transmitter and mount it discreetly on a nearby post or tree. Additional cable lengths are available for purchase if needed.
Increased Awareness and Security Monitoring Your Driveway
The DCPA-4K-PLUS Dakota Alert Driveway Alarm is an excellent choice for homeowners, businesses, and farm owners seeking increased awareness and security. By providing reliable notifications when vehicles enter or leave your property, this system offers peace of mind and helps deter unwanted visitors.

Uses for the DCPA-4K-PLUS
Excellent driveway alert system that will provide years of security for your home (or office) by notifying you when an automobile enters your driveway. This is an excellent 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 alert alarm kit.
Another potential option is to use the kit as a gate alarm. When a car or truck passes through a driveway gate, the probe triggers and transmits a chime signal to the receiver.

Just received this and have been working on setting it up. It is just as described. We just have to find a spot that our steel fence post, electric fencer and other metal objects will stop interfering. I’m sure we will love it once we work out our particular issues.
★★★★☆Kristen R.Oct 11, 2024
We purchased the magnetic alarm in June and we love the alarm - However, in September, it started to malfunction. Would go off without anything going over it. Upon inspection, the wiring had been chewed by critters. We were able to splice the wiring, and then we put all the wiring in continuous PVC pipes. We expect that the fix will be the answer! I suggest that if your wiring is exposed to the elements, including wildlife, you take the extra time to encapsulate it in PVC pipe!

Q&A
Questions & Answers
Answers from our team for DCPA-4K-PLUS Dakota Alert Vehicle-Only Probe Driveway Alarm.
Will people or animals trigger it?
No. The probe senses large metal objects, so it responds to vehicles.
Answered for 1800Doorbell
Can it text my phone?
No. For app notifications, add an SR-4000 smart receiver; it pairs with this kit's DCPT-4000 transmitter.
Answered for 1800Doorbell
Can I mount it on a metal gate?
The manufacturer recommends burying the probe. Metal near the transmitter can reduce range.
Answered for 1800Doorbell
Is cable included?
Yes, 50 ft of burial cable. Longer lengths are available.
Answered for 1800Doorbell
Does cable come with me kit?
Good afternoon. The DCPA-4K-PLUS comes with 50 feet of burial cable for the probe transmitter. Please let us know if you have any other questions. Thank you, Customer Support Team 1800Doorbell
Answered for Cathy S.
Can I get a second receiver for the magnetometer driveway alarm? I need to hear the alarm from more than one place.
Good morning. The DCPA-4K-PLUS is compatible with an unlimited amount of additional receivers and the model number for that receiver would be the RE-4K-PLUS. Thank you, Customer Support Team 1800Doorbell https://www.1800doorbell.com/re-4k-plus-wireless-plug-in-receiver-with-5000-ft-range-features-c-form-relays-and-12vdc-outputs.htm
Answered for Marc I.
Can the sensor be attached to a metal gate or metal post and still be effective and reliable?
Good morning. The manufacturer, Dakota Alert, recommends burying the probe but we have had customers install it onto a gate in the past. Metal is one of the biggest blockers of a wireless signal so it will have some impact on the signal strength, it would depend on how far the chime receiver would be from the outdoor sensor and if there are any other materials that would come in between. Please let us know if you have any other questions. Thank you, Customer Support Team 1800Doorbell
Answered for pmk
Can I program this to my phone?
Good afternoon. This kit does not send texts. For app notifications on your phone, add an SR-4000 smart receiver; it pairs with the DCPT-4000 transmitter in this kit.
Answered for White D.
Can you tell me about the batteries — how long they last, whether rechargeable batteries work, and how many are needed?
The sensor operates on three CR-123 batteries (included), which typically last a year or more before they need to be changed. If the RE-4k Plus receiver plays your transmitterâs tune twice and the LED blinks slowly for ten minutes after the transmitter is activated, your sensorâs battery is low. Replace the battery.
Answered for Kathleen R.
Can you set up multiple chime receivers on the same sensor so it can go off in multiple areas inside or outside of the home?
Good morning. Yes, the DCPA-4K-PLUS is compatible with multiple outdoor sensors and an unlimited amount of chime receivers. The compatible receivers would be the DCR-4000 or the RE-4K-PLUS. Please let us know if you have any other questions. Thank you, Customer Support Team 1800Doorbell
Answered for Michael Z.
Can you select the time of day it sounds to notify?
Good morning. You can not set the outdoor sensor to alert at a specific time but the chime receiver can be powered off or the volume can be turned all the way down. Please let us know if you have any other questions. Thank you, Customer Support Team 1800Doorbell
Answered for Brion S.
Are lithium batteries rechargeable?
No, these are not rechargeable. However, the estimated life is about 1-1.5 years and they are easy to find on Amazon or though us.
Answered for John F.
Is it line of sight for the 5000 feet how much will hills, trees and stucco on house affect the distance?
This is line of sight. Obstacles such as trees, hills, etc., will diminish the signal but we've found that outdoor factors have a limited effect, vs, concrete, steel, etc.
Answered for Richard T.
Does the sensor and reciever operate on batteries?
Good afternoon. Only the outdoor transmitter operates off of batteries, (3 CR123A batteries) the chime receiver plugs into a standard wall outlet. Thank you, Customer Support Team 1800Doorbell
Answered for anthony R.
Can the system be monitored on our cell ph?
Frank. Not at the moment, but this is a technology that will be rolling out within a few months.
Answered for Frank C.
Does Dakota make a driveway sensor with a phone app so I can receive the alert on my phone.
Good afternoon. Unfortunately, Dakota Alert does not have an option to connect to a smart phone at this time. They are working on this option for the future but we do not have a concrete date of when it would be available. Thank you, Customer Support Team 1800Doorbell
Answered for Customer
DCPT-4000. Have sensitivity as low as can be and it still goes off every few seconds. Not close to highway traffic.
Good afternoon and I apologize for the issue with the sensitivity. Dakota Alert handles all troubleshooting and technical support for their products. Please call Dakota Alert at 605-356-2772 between the hours of 8:30 AM - 5:00 PM CST Monday - Friday and a representative will be happy to assist you with the issue. Thank you, Customer Support Team 1800Doorbell
Answered for Howard H.
How do I get transmitter to connect to receiver over a small hill and then down hill to house?
The line of site distance for this product is up to 5,000 ft. This is line of site, without any interference. The hill could interfere, but it is very hard to say for certain. I would recommend you give it a try and if does not supply the range you need, return it within 30-days under our satisfaction guarantee.
