Using a Two-Way Radio with a Motion Detector for Outdoor Surveillance
When you have an area that needs outdoor surveillance, using a motion detector device that communicates with a two way radio is one solution. These devices allow you to monitor an area up to two miles or more away using a base station intercom or handheld two-way radio.
If you have personnel that need to remain mobile and still be able to monitor up to four zones, these motion sensing two way radios may be the ideal fit.
A device called the MURS Alert outdoor long range transmitter can be used to monitor driveways, trails, sidewalks, or any area you need to monitor. The MURS Alert Transmitter uses an infrared sensor and is mounted to a tree or a post to monitor activity at locations several miles away. If you only want to detect vehicles in your driveway, you can bury a MURS Alert Probe Sensor along side your driveway so you won't have false alarms from passing deer or other animals.
A MURS Alert can detect people, vehicles, or large animals, and then send an alert message to a two way radio or base station intercom. Up to four different zones can be monitored simultaneously using four MURS Alert units.
The alert message is not just a tone, but it is spoken in English three times repeating the phrase "Alert Zone One," "Alert Zone Two," "Alert Zone Three," or "Alert Zone Four" depending on the zone that has been triggered. The alert message spoken is easily selected during setup of the transmitter. The MURS base stations also have a relay switch that is activated when a zone is triggered. You can wire an external alert device such as a bell or siren to this switch for a louder alert.
MURS is short for Multi-Use Radio Service. This is a newly created service by the FCC in the United States. It is a low power, short range service in the VHF (Very High Frequency) 150 MHz Citizens Band radio spectrum in which you do not need a license to operate a MURS station.
The MURS Alert Transmitter and Probe Sensor have five channels and 38 sub-channels to choose from to help eliminate interference from other users. 
The extended range of the MURS Alert Transmitter and Probe Sensor helps in monitoring areas that have been very difficult to monitor in the past. This solution provides great value to businesses trying to monitor customer traffic, security guards trying to monitor remote warehouses, farmers monitoring vacant farm sites, and hunters monitoring game trails. MURS Alert gives real time monitoring of any location you choose.
