A wireless home alarm communicates or sends signals to the control unit through radio frequency signals (RF). The sensors for the wireless system are strategically located around the house, in windows, doors, and any other area that may allow access to the home. These sensors are unobtrusive, until something interferes with the signal given out by the sensor. When the sensor detects motion or activity it sends a wireless message back to the central control panel. Some systems have been designed to use infrared beams as well. When the system is armed, the detectors monitor the surrounding area for motion (actually registers as a temperature difference) and send the signal to the control unit.Learn more about at best wireless alarm system website
While all the sensors are wireless, the control unit(s) are not. These need to be wired into the home for several reasons, one of which is being wired into your phone line. This is how the system communicates with the monitoring station. Some new systems offer wireless communication through your ISP as well. Regardless, the installation of the control units is minimally invasive for your home.
Once the control panel sends a telephone call, one of two things may occur. Either it immediately places an automated telephone call to the local law enforcement agency or it calls a subscription based monitoring system. Occasionally, the control panel will also sound an audible alarm, but most homeowners prefer not to use this option, because it makes it more difficult to catch intruders in the home. A silent alarm allows responders to reach the home before the intruders realize that they have aroused suspicion.
If there are elderly family members in the home, young children or anyone with health problems or disabilities, you can include panic buttons that will alert the monitoring company and medical response authorities. Water monitoring sensors for areas in a home that are susceptible to flooding are another popular option as are carbon monoxide detectors. There are numerous other aspects that can be added, such as wireless video cameras and wireless arm/disarm devices that can be carried on your key ring for better security options.
