There are two different detection devices available. One detects motion and the other metal. The motion detector as it sounds will detect movement of vehicles, people, and large animals. If you live in an area where there are frequently deer around, you may get false signals caused by the deer.

You can get detectors in wireless and wired. Of course the wired system requires you to run a wire between the sensor and the monitor whereas the wireless detector doesn’t.

If you only want to detect vehicles, then you can get a detector with a metal detecting probe that is buried next to your driveway. With the probe, you won’t have false alerts cause by animals or people.

If you have a short driveway (less than 500 feet) the WireFree Wireless Alert System with 2-Way Voice Communication can be used. Not only will it tell you when it detects movement near the sensor, it will also let you carry on two-way communication with whoever is near the sensor. No metal detecting probe is available for this unit.

If you have a driveway as long as a couple of miles you can still use wireless driveway alarms. The MURS Alert has a range of up to four miles in perfect conditions, but realistically it should easily reach two miles under most conditions. It will sound a verbal “Alert Zone One” message when the sensor is triggered. This system has either a metal detecting probe or a motion sensing option. You cannot talk to the sensor like the system above, but you can use the monitor unit as an intercom system by adding additional monitors.

You can use these driveway alarms for more than just monitoring driveways. They can also be used for security applications as well. Both systems can be found at IntercomsOnline.com/

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.

The solution was the MURS 4-Mile Range intercom system along with the MURS Alert Transmitter.  We carry this as the MURS Base and MURS Alert Kit which can be found under the Driveway Alarms section of www.IntercomsOnline.com .

He placed one intercom in his house and one intercom in the workshop. That took care of the wireless intercom communication between his home and shop. He placed the MURS Alert Transmitter in the workshop, which then sounded an “Alert Zone 1″ verbal message on the intercom in his house whenever it was triggered.
