Dakota Alert Wireless Driveway Alarm Sensor - DCMT-4000 Long Range, Passive Infrared Motion Detection, Home Security, Backyard Monitoring, Entry Alert, Wireless Doorbell

Useful device and a good addition other Dakota Alert receivers (DCR-4000 RE-4Kplus) because it's portable and also keeps a timestamped log of alerts organized by Zone. LCD is backlight. The 4 buttons (Power, Mode, Up, Down) have tactile feedback and are easy to push and difficult to accidently activate.Range and orientation sensitivity should be similar other Dakota Alert units because it uses the same helical antenna (it would be nice if they indicated antenna/device orientation for best or worst Tx/Rx performance).Has a optional haptic/vibration alert (like cell phone) and volume adjust for the speaker.Criticism are:1. The keys lockout after 12 seconds and require pushing the Up and Down arrow together to reactivate. The display shows a key icon to indicate "lockout". Lockout isn't needed and should be user configurable setting.2. The unit shows TTL (total) and the zone number. You must push the Power button to erase the Zone/TTL line before the keys are responsive. Unclear why this is needed, but it's annoying.3. To see the traffic log, you must push Up+Down (to unlock), then push the Power (to erase Zone/TTL), then push Mode+Down, then begin scrolling through zones. (Keep the manual handy).4. Still uses USB-Micro charging port (although the supply a USB-A to USB-Micro cable).I'd buy it again.

Needed an extra receiver for our system. Super easy to pair with transmitter. Transmitter and original still working like a champ

It works well and the sounds you have on it are real nice. Thank you

I bought this to replace an older Dakota Alert Series 3000 which finally died. This new one is much better. I've had it up and going for nearly a week and have not gotten a single false alarm nor has it missed any cars pulling into my driveway. Setup was simple. The signal seems powerful. While I only have it about 75' from my house, my house has steel siding and the signal gets through. I have a second receiver in my basement and I get a signal there.I had a couple minor questions and Dakota Alert's customer service was quickly responsive and helpful, getting back to me within the same day. Very good customer service.Why I didn't give it five stars: 1) there is no off switch on the receiver, you've got to unplug it. 2) The clam-shell plastic case on the transmitter seems much less rugged than on the old 3000 series, and I worry the case will warp and let water in over time. No way to know though.

This is a replacement for the exact same item I bought probably 20 years ago when I moved to this house. Our last one of 3 finally died when ants invaded it. Can't complain on the longevity. We have a1/4 mile long driveway fully covered with trees. It picks up great. Use it with the Dakota detector.

Had one of the older Dakota Alerts for many years. Worked excellent, until a woodpecker drilled a hole on the motion sensor. Ordered the newer one, hope to have many years knowing when someone is in my driveway!

Setup and instructions were pretty easy. I initially bought this as an additional security measure because I've had a car prowler a few times that was captured on my Arlo but didn't know they were around. The most shocking time when we were watching tv around 6:30pm and it was dark outside. With the other cars we have in the driveway, I had no idea until a neighbor stopped by and said he chased the person away.My driveway and gravel area is about 30' wide and with the monitor set at the 50' range, I have the entire area including part of my front yard covered. It's been an excellent little monitor for getting notifications when a car happens to pull in, or when a package is being delivered and we're in another room. The IR beam is very narrow which is great because I was worried about it going off when someone is walking their dog or cars for that matter.Some people have mentioned a lot of false alarms but we haven't had that... maybe a handful or so over the last 3 months (all in the day). I will say this, in the mornings or when a car is cold (mainly white cars) it fails to trigger, but I don't consider that a deal breaker.When I got the Dakota DCMA-4000, I did need to reach out to their support after about a week or so because after adjusting the dip switches and testing, I noticed the receiver was blinking but there was no audio. I reset it per the instructions and paired it again and same result. Support (which was really helpful btw) told me that since I bought on Amazon, they may have had an older product that had the faulty speaker because they got reports of the speaker not working. They mailed me out a new speaker and was able to unplug the old one and replace. Sure I could have returned/exchanged for a new device, but figured since I was within my return window, this was a quick fix and it did resolve my issue.
