Wireless home security is an electronic system designed to alert the occupants of a home to an attempted break-in or to an intruder actually in the house. Many home security systems have the option of being installed in a home wirelessly, greatly reducing the cost of installation as well as improving the defense of the system – without wires, potential burglars cannot locate and disable main power lines that would disable the system. There are a number of different parts to a wireless home security system:
Control panel
This is the essential part of any homes security system – it monitors the alarm system’s sensors, has the ability to trigger an alarm, and can call pre-programmed phone numbers, usually the local authorities or a monitoring station, if the homeowner is subscribed to one. It is operated by a keypad, which can arm and disarm the system as well as disable a triggered alarm; because of this, the keypad is installed out of sight in order to hinder a burglar who may attempt to locate the keypad and disable the system.
Security sensors
These devices monitor the surroundings in various ways (usually through movement, involving infrared imaging, ultrasonic sound waves, microwaves, and sound detection, among other methods) in order to detect intruders. If a sensor is tripped, it sends a message to the central control panel, which then triggers an alarm.
Door and window contacts
These are small, two-part devices that are installed at all doors, windows, and other entryways to the house. When the door or window is closed, the two parts (attached to the door and the doorframe) connect, completing an electrical circuit; if the system is armed and the door is opened, the circuit breaks, sending a message to the central control panel to trigger the alarm. These can also be set to simply beep or ding when a door is opened, allowing parents to monitor children entering and exiting the house without any loud alarms being set off.
Alarm
The alarm is the part of the system that alerts occupants, neighbors, and, in the case of a silent alarm, the police to the presence of intruders in the home. These can consist of bright, flashing lights, loud sirens or bells, and other attention-grabbing devices. If the alarm is set off due to a false positive, it may be disabled at the keypad if the user has the correct security code.
With proper planning, wireless home security is a reliable, cost-effective method of providing for the safety and well-being of the occupants of a home.
