Dakota AlertWireless Driveway Alarm Portable Receiver PR-4000 - Compatible with 4000 Transmitters | Battery-Powered Monitor Comes with USB Charger & Belt Clip, Driveway Alarms Wireless

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.

Nice portable receiver. Only minor things I dislike, maybe I'm missing something, is that there is no scroll feature concerning multiple alarms. It only displays the number of alarms since last clearing and time of the last alarm. Second, as the internal battery weakens, the battery level bars disappears one by one. With mine, one bar disappears as it's used, then when it's time to recharge, the display just goes completely blank with just a barely visible battery level bars. In other words, it doesn't work like a cellphone battery indicator where it goes down just one bar at a time. Mine, just BAM.... Surprise, surprise. Dead receiver. I'll watch and see if this is a continuous issue.

I had been using this to cover a gate for many years with the 2500 and 3000 series.The new 4000 series seems to work much better.People walking by will set off the alarm but I wanted it to detect vehicles waiting at the gate.With the old system it was a bit hit and miss but the newer system has not so far in 2 weeks failed to detect a vehicle waiting at the gate.One problem with this system is that it will work great with a car which is warm but often fails to pick up a car exiting which I put down to the car not warm.As is used to detect a vehicle arriving then the chances are it will not be a cold just started up vehicle this has worked OK for what I needed.If you would need it to be 100% on vehicle detection on warn or cold vehicles then it maybe better to go for the probe version or the rubber hose version.I could not use the probe as is too close to the road and next to a large metal gate.I did also buy the rubber hose version but have yet to try as this is so far doing the job and I still have not been able to straighten out the rubber hose which came coiled up.The new style pager receiver is almost twice the size of the old style but battery lasts much longer and is much more reliable receiving a signal.I have found it well worth the money and works much better than the older 2500/3000 series.

Works great…so far not a single false alarm

It keeps a nice record of when the motion detector triggered, which is unusual in motion detectors, and very important.I find I have to recharge the unit more than once a week. It does not have a standard AC plug for constant use. I could leave it plugged into the charger all the time, but that can be dangerous for lithium ion batteries. Too many steps to clear the motion detection history: press 2 buttons, press 1 button, press 2 buttons, press 1 button, press 1 button. I may have missed a step. Extra button pushes to select different zones.
