Product Description

Don’t be caught off-guard… Wireless Driveway Alert and Alarm System warns you that visitors are on their way to your door This driveway alert system uses a wireless receiver in your home that will chime when the infrared driveway alert sensor outside detects motion, so you’ll be prepared for that unexpected knock at the door or beep in your driveway. This driveway alert's wireless motion sensor mounts outside on a post or wall, and you can set the receiver anywhere in your house (within 200 ft. of the sensor). Completely wireless installation Weather-resistant plastic housings Mounting hardware included Requires one 9 volt and three C batteries (sold separately).

80 customers mention48 positive32 negative

Customers are mixed about the sound quality of the tool. Some mention that the loud setting is clearly audible over the table or radial saw, and the quiet setting is just loud enough to awaken them. They say the alarm has a nice bing-bong sound and the receiver is portable. However, others say that it was either too quiet or so loud that it would make them jump. Some customers also mention that it became very irritating listening to it beep.

"...I've had no false alarms. The base comes with two volume settings and I use it on the loudest setting so that it can be heard throughout the house...." Read more

"...There is no way to reduce the sensitivity. I have a very long driveway so I wanted to know if any one was coming up to the house...." Read more

"...Overall this system works just as intended. The sensor is great!!" Read more

25 customers mention15 positive10 negative

Customers are mixed about the range of the tool. Some mention that it has a great range and wide receiving area, making it perfect for long driveways. However, others say that it had only a 5 foot range and the signal could not get through to the receiver.

"...the area being monitored is under 15 inches, so it's reliable for close range indoor montoring. 5 Stars!" Read more

"...because our mailbox was enclosed in a brick housing and the signal could not get through to the receiver...." Read more

"Works great, and the distance is amazing. However be careful placement. Aiming it for the desired area coverage is critical." Read more

"...I cannot leave it on at night because it goes off several times a night over nothing. I now use it when I am expecting someone then turn it off...." Read more

"...It goes off very often for no other explanation. Nothing visible as I look out to see what made it go off...." Read more

"...The first one lasted for a year until it started going off for no reason. I really like this unit when it is working...." Read more
