Rated 3.7 out of 5 by 120 reviewers.
Rated 4 out of 5 by Working Chamberlain Motion Sensor with Wireless Motion Alert CWA2000 For the most part, works exactly as advertised, as you can see we mounted it within a shelter....reason for less than perfect rating is occasionally the sensor doesn't sense! Beeping alert is of nominal volume, probably wouldn't be heard if mounted in workshop, mounted in office, volume is satisfactory. Would guesstimate efficiency at around 94%. Curious to see how it fares this winter.....all in all, a good purchase. November 5, 2014
Rated 4 out of 5 by Works well, but alarm sound not very loud... I bought my 1st driveway alert, a Dakota, from Cabela's over 10 years ago. The sending unit was a large green box that I mounted to a tree. The house receiver announced passage with a crazy buzzing choice of doorbell rings and could be VERY loud. It worked well for us for years. We have moved to another home and had the need to announce visitors coming into our driveway. I chose this Chamberlain model based on my experience with their garage door openers. It takes only minutes to install batteries and pair the transmitter to the receiver. The unit is a very neutral tan color and is not obtrusive attached to a tree next to the driveway. Hardly noticeable. It works very well. The receiver, however, even on the loudest volume setting isn't very loud, and it is plugged into the wall socket using the supplied power transformer. I gave this review 4 stars for the sound volume settings. Otherwise, a good buy! July 13, 2014
Rated 5 out of 5 by Good strong alert signal! Some reviews indicated the alert signal was not loud enough. I strongly disagree. With the vol. turned up high & alert placed in the middle of the house, the alarm can be heard from both ends of my 3300 sq ft one story spread out house, even with the tv's on. The frequency is high & perhaps the people that have difficulty hearing the signal may have a what is called noise induced hearing loss which occurs in the higher frequencies and also occurs with natural aging. I'm not being faciscious as I am a Speech and Language Pathologist. Also the sensor is on the exterior side of my 7" iron & wooden driveway gate more than 40' from the garage, yet the signal easily reaches the interior of my house. I give this a 5 star product.

Rated 5 out of 5 by Great product Very good deal, This driveway alarm is just what I needed. The distance between the base and the sensor is about 200 feet and a lot of metal siding plus mounted on a metal fence post. The alarm detects all traffic whether its cars or people up to 45 feet, well beyond the stated 30 feet. I'm very pleased with this product and would recommend it. April 29, 2014
Rated 5 out of 5 by Works as advertised. A good product to monitor those remote areas. Our dreiveway winds down off a ridgeline where our home is located. Where it enters the main road is invisible from the house. The product provides an early warning for vehicles entering our driveway that may be approaching the house so we are prespared to see the vehicle as it approaches the ridgeline. April 8, 2014
