Recent Home Security News
Many house alarm systems work by sending a signal to a central monitoring location when a break-in is detected. These locations then contact the local police, who come to your home. These systems sometimes issue false alarms, so do check with your local police about their false alarm policies before installing a centrally-monitored security system.
An electronic security system may be hardwired or wireless. Hardwired systems operate on low-voltage electricity and typically include a step-down voltage transformer, a master control panel, several remote-control pads, and a series of contact switches and sensors. Wireless systems consist of battery or AC receptacle powered sensors and contact switches that contain independently operated alarms. They may use a radio frequency to communicate with a control panel.
A wide range of perimeter sensors is available, from magnetic switches and plunger switches for detecting when doors and windows are opened to ribbon sensors for detecting when glass window panes are broken. You may also wish to install motion sensors or heat sensors at specific locations in your home, or even pressure-activated sensors under carpeting in entryways and on stairways. Some whole-house security systems include a remote control panic button that can trigger an alarm from anywhere in the house.
