Unlike PIR (passive-infrared) based driveway alarm sensors, the DCPA-4000 kit by Dakota Alert is a drive over driveway alarm, meaning it has an underground driveway alarm sensor that is buried underground and detects cars or other heavy metallic objects.  This is ideal when you live in a rural area or want a driveway gate alarm, or any area for that matter, where animals may trigger your sensor.   When a car or truck passes within 10′-12′ ft. of the buried probe, the sensor transmits a wireless signal over 5,000 ft. away to the receiver.

This kit features two main components; 1 x DCPT-4000 Magnetometer Probe Transmitter and 1 x DCR-4000 Plug-in Chime Receiver.   The transmitter is a magnetometer driveway probe buried in the ground parallel to your driveway or even under the driveway (if the driveway is dirt or gravel).  The probe has 50′ of wire connected to a transmitter box powered by 3 x CR123a lithium batteries (included for domestic orders, not international orders).  When a large metallic object passes through the magnetic zone (10′-12′) emitted by the probe, it triggers the transmitter to send a signal to the compatible receiver. It does not trigger until a car drives over or near the buried magnetometer probe sensor.

As stated above, the transmitter/sensor is buried underneath the driveway or parallel. If you want to use it for a driveway gate alarm, it must be buried under or directly parallel to the driveway gate. The driveway probe sensor ships with 50′ of wire that connects the buried driveway sensor to a small black box. This box is usually mounted on a post or a tree near the driveway. When a metallic object drives over the probe, the black box transmits a radio signal up to 5,000 ft. to the compatible receiver, the DCR-4000, and/or the PR-4000 portable vibrating driveway chime receiver.

The receiver in the kit is the DCR-4000 receiver.  Simply plug the receiver into a standard wall outlet and program it to the transmitter/sensor by picking one of twelve available melodies.  When triggered, the receiver will play that tune.  The receiver may be located up to 1 mile from the transmitter, line-of-site.  Environmental factors such as hilly terrain, wooded areas, and building materials will reduce the transmission range; however, with a range of up to 5,000 ft., this setup works in most scenarios.

The receiver has 12 sounds, with four-volume adjustment levels from mute to approximately 85 dB.  The transmitter and receiver are compatible with all Dakota products in the 4000 series, such as the UT-4000 and the DCMA-4000 Driveway Monitoring System.  This means you could add receivers throughout your home or office to distribute the sound, pushbuttons, and PIR-based motion sensors to your system.

Easy to put in it works great

This is my 2nd driveway alarm. The Dakota is better than my 1st. Easy to set up, easy to install. Great choices of sounds.

What a great concept!

My husband found this item online, and since we have a long rural driveway (1000') with a farm gate, and our house can't be seen from the road due to all the trees, a "remote doorbell" seemed like such a great idea -- and it is! He installed it a couple of days ago, and so far it has rung twice: first when Fedex came and second, UPS! It was fun going through all the tunes, and since the Canon in D was one of the songs played at our long-ago wedding, that was of course our choice. It works well, has an incredible range, and is just perfect for our needs. Reasonably priced too!

Works great

Haven’t completely installed as the ground is still frozen but it’s working great sitting beside my driveway. Good volume and choices on the alert. No false alarms. When installed the distance will be about 800 ft from the house/ receiver. Was easy to set up. Definitely worth the $.

L.L. (Richmond, US)

We had an old version of your hose driveway alert and were very satisfied. It even survived 6 coyote pups using it to play catch the hose in mid air and tugging it as hard as they could. We decided to upgrade and ordered the new sensor version. We installed it over the weekend and it worked perfectly. My husband and I highly recommend your product.

C.N. (Little Rock, US)

This product is excellent, well build and extremely easy to setup. I rate it extremely high. Mine is working at a long distance around a curve.

Driveway alert success

Finding the correct driveway alert was not easy. But once I did, I’ve already installed my second one. Quality product that does exactly what it is meant to do.
And ordering it directly was absolutely flawless.
Thank you.
