DCMT-4000 Motion Sensor

This works so well for our 10 acres. No problems at all. The only problem I have is that 2 main receivers were sent to me by accident. I ordered one receiver, I received the sensor first, then I realized the receiver was supposed to be delivered at the same time but the order was still sitting in MY HISTORY, so I ordered it and I ended up receiving 2 total. Now I’m getting charged to return one, which I think that was completely AMAZONS error.

This thing is great. Easy set up, works consistently. Only phantom alarms were when a horse knocked it over and it filled with rain. Shook it out and back up and running.

We had a DCMT 2500 several years ago, but did not install it on our new property because it was not compatible with the newer DCPT 4000. We added the DCMT 4000 to our system to let us know if there is anyone walking down our driveway. Yes, the DCMT will also detect vehicles, but does not do so consistently, especially in winter compared to the DCPT. The DCMT does do a good job detecting animals/people though.

This is the second one we have owned from this company. First one lasted 13yrs. We have a 1/2 mile lane. It will read clear out to the other cross road. But... everything someone drove by the gravel dust would set it off. Just move it up our lane 200ft. And it works great. Highly recommend this driveway alarm

two work fine, another two work sometimes "if stars are aligned" , tried these as I got fed up with the MURS, Time to look for some other manufacture

The first 2 we had last 12 years change battery once a year work great we have ours 300 yards from base and no issues at all

These are a massive downgrade from the original Dakota Alerts. They claim long range. Absolutely not true. I have one in a straight clear shot just 100ft from my house and it often times doesn't go off. I have 4 of these total and have rotated them all out to that same spot. All are hit or miss on detection. Through extensive experimentation, I figured out that the max one will work is 400 feet when going through a window with no obstacles. And it only went off 1 time out of 25 times of walking in front of it. These are junk and a bad investment.

I BOUGHT THESE SENSORS ALONG WITH THE TONE CHANGING RECEIVER. THE FURTHER MOST ONE IS BEHIND A BUILDING WHICH IS ABOUT 275 - 300 FT AWAY FROM HOUSE. REACHES MY RECEIVER INSIDE HOUSE WITH NO PROBLEM. THESE SENSORS ARE MORE DIRECT BEAM, NOT MUCH UP-DOWN , SIDE TO SIDE VIEW. IF YOUR APPLICATION JUST REQUIRES A BREAKING OF THE BEAM, THEY WORK PERFECT. WITH THAT SAID, IT IS BETTER TO AIM BEAM ABOUT WAIST HIGH OR HIGHER TO DETECT HUMAN MOVEMENT AND THIEVES , AND NOT ANIMALS. I'VE NEVER HAD A ANIMAL STEAL ANYTHING. ALSO THE TONE CHANGING RECEIVER WORKS GREAT AS TO DETERMINE WHICH AREA IS TRIPPED. HOPE THIS HELPS.
