Mighty Mule Driveway Alarm is rated 4.0 out of 5 by 4.
Rated 1 out of 5 by from No luck with mine I'm on my 2nd one.the first one worked most of the time then it began to go off for no reason. I replaced the batteries (1.59v) and no change. The 2nd one works about 1/3 the time. If a car is going too fast (7mph or more)it won't pick it up. It's supposed to have a 12ft radius but it's more like 7ft even with the sensitivity turned all the way up. Boo!

Rated 5 out of 5 by from Seems to be a good purchase! This driveway alarm was a little more difficult to install, but appears to work much better than previous alarms.

Rated 5 out of 5 by from Great Driveway Alarm We love this alarm so much, we have 3 receivers! One upstairs, one downstairs, and one in the backyard by the pool. No we know when guests or deliveries arrive! It works great! Even transmits through concrete walls!

Rated 5 out of 5 by from Awesome product!! I purchased this about 3 years ago and have been very pleased with this product. It has been working flawlessly. You can't beat this driveway alarm for the price.

Is this just a motion detector? It will pick up large dogs too? Or does it just detect vehicles? 

Asked by: Curiour
Curiour, Thank you for taking the time to post your question. The Mighty Mule Wireless Driveway Alarm only detects mass metals in motion. It would not be set off by animals or humans. Thank you.

Where is battery located and what type of battery

Asked by: Mighty
Hi, this unit requires 2 AA batteries that are installed in the transmitter case, this is the part connected to the mounting post that is installed outside. The indoor base station receiver includes a transformer that is plugged into an outlet and does not require a battery.
