CUSTOMER REVIEWS

Rated 3.9 out of 5 by 161 reviewers.
Rated 5.0 out of 5.0 by A great buy! I purchased this product over 6 months ago and it has worked perfectly. No false alarms which was a problem with my previous driveway alarm which was sensitive to animals and temperature changes. I have a long driveway, so there is relatively little traffic that could create a false alarm. I have the sensor installed about 75 years from the base station. Given the price of this unit, I expected it to be too good to be true. But I was wrong. I'd highly recommend this product for anyone looking for a driveway sensor. December 24, 2012
Rated 5.0 out of 5.0 by Paranoid in the country Takes some work to install, after that it has worked flawlessly for 5yrs. Only replace batteries once a year in the spring. Have the distance maxed out at about 425ft. Wish it had an add on capability. Would love to be able to turn the front porch light on each time it goes off. Plan on getting an addional receiver for the work shop. March 9, 2015
Rated 3.0 out of 5.0 by OK Compromise that works. The product works, but not quite as well as it might. The detector does not detect a vehicle 12 feet out as stated. Ours detects it at about 2 feet with the sensitivity set at max. I checked that using the LED test. We have a woodland habitat and even at less than 100 feet would not communicate between the transmitter and receiver. I placed the transmitter about 8 feet up in a tree, instead of on its one foot tall post, and that fixed the problem. This product is cheaper than one of the pressure sensors (which in retrospect I would have purchased instead) and it does not have the problem of moving branches that a passive IR system has. So as I say this is a compromise that works. June 2, 2015
Rated 5.0 out of 5.0 by Very good driveway alarm Driveway alarms have gotten better and cheaper over the last 10 years. There are basically 2 kinds; the magnetic sensor (like this one for vehicles) and the motion sensor, for people, animals, vehicles and anything that moves. Motion sensors tend to give more false alarms do to branches or brush moving in the wind. This one has been working very good for me. I found a spot about 150 feet away with a pretty clear view of the receiver to mount the transmitter. I slid the sensor in a 3" PVC culvert that ran under the driveway, it even picks up my bicycle when I ride over that spot. Keep in mind the line of sight from the spot where you mount the transmitter to the receiver in your home and try to avoid obstacles that will block the signal. The 400 foot (listed) range would only be for optimal placement without any signal interference, 250 feet is more realistic. June 17, 2014
Rated 4.0 out of 5.0 by Works like it's supposed to. Works great with no false alarms. Installing was not easy, as I had to bury the sensor and wires, but it works as it needed to. The only suggestions I would make would be to increase the length of the cable from the sensor to the transmitter and I would like to see more volume adjustments in the receiver. Other than that I think it's a great product. June 17, 2015
Rated 5.0 out of 5.0 by good product was able to set it up without any assistance. It is a very good product. I follow the instructions provided ans so far, I have experienced no problem. June 17, 2015
Rated 4.0 out of 5.0 by Driveway alarm that works Very easy to set up and works as expected. The alarm sounds in the house whenever a vehicle comes up our driveway. June 16, 2015
Rated 3.0 out of 5.0 by Driveway alarm My house is 500' from the road so we lke to have an alarm to let us know when someone comes on our property. Like this better than infrared alarms I've used that can be set off by deer, rabbits and other animals. Only goes off when cars, trucks and other large metal objects cross its path. But I found they were a little off on some of their distance claims. I had to bury the sensor wand within a foot of the edge of the driveway. The 12' circle they claimed didn't work for me. they also say it works up to 400' feet away. I first had the sending unit 300' from receiver and it didn't work, had to move it to 200'. Would like to have a softer alarm sound but guess you can't have everything. April 21, 2015
