A customer had a driveway that was about one mile long and they wanted to be alerted when someone was coming down the driveway. They did not want to run a wire that far so they wanted a wireless solution.
The MURS Alert Kit had all the features they wanted and more. It is a long range wireless driveway alarm that consists of a wireless intercom and a wireless motion sensor. It is capable of up to a four mile range. When someone is coming down the driveway, the motion sensor sends a verbal “Alert Zone One” message to the wireless intercom. They can have multiple wireless intercoms in their house. They can also use these intercoms as intercoms for internal communication.
There is even a handheld two-way radio that works with this system so they can be roaming around their property and still know when someone is coming down the driveway.
There are two sensors available, one probe sensor that gets buried along the driveway and only goes off when it detects metal. The other detects motion.
