Wireless Burglar Alarms – Home Security Without a Phone Line

Cellular Burglar Alarm

The invention of land-line telephones dates back to the late 1800’s. The patent for the telephone was credited to Alexander Graham Bell, on March 10th, 1876. However, his invention would not have been possible without the 1831 reserach of Michael Faraday, who discovered that vibrations in metal could be converted into electrical impulses. In 1861, Johnann Philip Reis was able to succesfully construct a device which could convert sound into electricity, then back into sound. However, it was Alexander Graham Bell who is today recognized by most experts as being the father of the telephone.

Over a century later, it could be argued that the technology of the land-line telephone may be on its way to extinction. In fact, over 20%  (roughly 20 million) of homes today communicate only with cellular phones, without having a land-line telephone installed. When it comes to home security, this can often present a problem, since many monitored home security systems rely on having a constant telephone connection in order to report an emergency. If you’re one of the households without a landline telephone (or simply want a system that doesn’t rely on a phone line) you may want to look in to investing in a Wireless Burglar Alarm.

Practicality of Wireless Burglar Alarms

Since a wireless burglar alarm doesn’t need to be constantly connected to a phone line, it can be used even in some emergency situations. Some burglars may cut the landline before entering a home, assuming that this will also disable the security system. If the phone lines in your area are damaged, it can prevent your monitored security system from reporting an emergency. A wireless burglar alarm provides both a practical and useful solution to these problems.

How It Works

Cellular monitoring works a bit differently from traditional security monitoring. The security system usually comes with a digitial cellular transceiver, which is installed directly into the system’s control panel. To activate the service, you usually need to establish a service contract, which will cost you extra each month. The terms of this contract depend on the company from which you receive the cellular service.

When the system detects an intrusion, one of two things may happen:

  • If the system is designed to work as a backup to an existing landline phone, it will first check for a landline dial tone. If no dial tone is present, the system will use a wireless cellular signal to reach the monitoring station.
  • If the system is designed to work as a replacement for a landline monitored security system, it will immediately use the cellular line to broadcast an elert to the monitoring station.

Add-On Features

A security system that uses wireless monitoring technology can usually be integrated with most of the same sensors as landline security systems. This includes:

  • Carbon Monoxide Sensors
  • Smoke Detectors
  • Glass Break Sensors
  • Motion Detectors
  • Video Surveillance
