Go with the 4000 since you soon will not be able to buy components for the 2500. The 4000 receiver is smaller with the addition of a light and is a much better design. **Q: How long does the battery last?** A: Mine have been working for 16 months without being replaced. And they trigger probably 4 times a day minimum. **Q: On the dakota alert dcma-4000 wireless detector driveway alarm system can the transmitter send signal to two receivers at same time?** A: OFFERS AN EXPANDABLE ALARM SYSTEM - You can add up to 16 different transmitters to the DCR-4000 Receiver if you wish to monitor a larger perimeter. DCMA-4000 is not compatible with 2500 or 3000 series products. **Q: Can you power this with POE?** A: Sorry, Power Over Ethernet is not an option. The receiver is powered via a plug in transformer that goes from 110 VAC to 12 VDC. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent driveway detector *by M***. on 9 July 2026* Works well, sometime false alarms from weeping willow branches 9 volt battery is ideal for long life and easy change out Solar units didn't work under trees in NE Alarm tone not too obnoxious and is changeable So far best we've had. AA battery units didn't last and battery terminal board cracked. Trashed them and the solars. Primary reason to buy was 9 volt transmitters So far, would buy again ### ⭐⭐⭐⭐⭐ Great product *by A***R on 2 December 2025* Awesome unit spot on ### ⭐⭐⭐⭐⭐ You will need to use a UK plug if using in UK *by G***6 on 8 December 2023* I brought this as an upgrade to the older 2500/3000 series' It comes with a USA 110v power supply so if using in the UK you will need to source a power supply. I was lucky because the old UK power supply I was using on the old system fitted. Is a good upgrade on the older system and is more reliable at detecting vehicles. ## Frequently Bought Together - Dakota Alert Wireless Receiver- DCR-4000 Up to 1 Mile Operating Range - Compatible with All Dakota Alert 4000 Series Sensors: SBB-4000, DCHT-4000, DCMT-4000, DCPT-4000, and UT-4000 Transmitters - Dakota Alert Wireless Driveway Alarm System DCPA-4000 One Mile Wireless Range, DCR-4000 Receiver & DCPT-4000 Vehicle Detecting Probe Transmitter with Direct Burial Cable | Outdoor Vehicle Sensor Alarm - Dakota Alert Wireless Doorbell - UTDCR-4000 One Mile Long Range Wireless Door Bell 4000ft, Doorbell, Panic Button, Mailbox Alert System, Universal Transmitter & DCR-4000 Wireless Receiver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/268002690-dakota-alert-dcma-4k-plus-perimeter-alarm-system-with-relay](https://www.desertcart.us/products/268002690-dakota-alert-dcma-4k-plus-perimeter-alarm-system-with-relay) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-18*
