Our longest ranged electronic probe is an extremely reliable driveway alarm that is used to detect vehicles only. The transmitter operates on 4 "1111A" batteries and has 50 feet of direct burial wire connecting the probe to the exterior case. The probe is buried parallel to (not across) the driveway and will detect vehicles passing by within approximately 10-12 feet.
The wireless probe driveway alarm is the most reliable driveway alarm we carry and is ideal for locations where there may be deer or other large animals that would cause false signals with other driveway alarms or motion detecting systems. Also, because the probe is buried underground, it will be the least noticeable of all our wireless alert systems. The MURS Alert will give you real time monitoring of remote locations up to four miles away (actual range will vary depending on the local terrain). The MURS Alert has many different applications; it can be used by security guards, small businesses, or home users - any scenario that requires immediate notification when someone or something enters a monitored location. Authorized by the FCC, MURS is a license free service that allows the user to transmit voice and data. MURS also allows communication between the receivers; a maximum of 2 watts of output power. This means greater range than other license free radio services.
