Dakota AlertDCMA-4000 Wireless Motion Detector Driveway Alarm System - DCMT-4000 Passive Infrared Transmitter and DCR-4000 Receiver

Works great…so far not a single false alarm

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.

I use this for a driveway alarm. I already had this system so I knew it was good. I just added to what I already have.

The mounting plate with ball swivel is not tight and the weight of the sensor unit makes it drop so it faces the ground. Had to put glue in the ball joint to make it immobile. The alarm set up is a bit finicky and not real loud, you may not hear it from another room. I’m using mine to monitor my peach tree that gets pilfered by people from apartments.

Very easy to install. I needed 650 ft range and this fit the bill. Works well and now I know if someone is coming down my driveway.
