How a Wireless Home Security System Works?

The components of a wireless system are similar to a wired system, however as the name suggests, there are no wires involved in this case.  The components may include sensors, detectors, alarms, cameras and a main control panel.

Wondering how a wireless home security system works? We can explaine how a wireless system actually works once we know about the components which are used in wireless seccurity as follow:

Main Control Panel

The control panel acts as the nervous system that communicates with every installed home security component. It arms and disarms the system and is also designed to sound the alarm in case of a break in. You can choose to have the panel in your bedroom, near the main door, or anywhere where it is easily accessible. The control panel may use your phone line to alert the service provider and the local police department, if programmed to do so. In order to operate the control panel, a pass code is used. Some control panels also work through voice commands with the help of wireless remote controls called key fobs. 

Sensors and detectors

Sensors are designed to detect any intrusion, break-in, or any other breach of security in and around the house. These components employ different technologies such as infra red, ultra sonic or microwave to detect. Magnetic sensors are also used to monitor doors and windows. The different types of sensors available are motion, noise, window, infrared etc. A sensor, upon detection of a break in is designed to send signals to the main control panel and alarm. These sensors are usually battery operated.

High decibel Alarm

Alarms are designed to go off after receiving information of a break in from the control panel. The alarm should be loud enough to inform both the occupants and the neighbors. Some may prefer a silent alarm that discreetly informs the occupants and the local authorities. This is to make sure the perpetrator is apprehended during the act.

Wireless Cameras

Wireless cameras can be accessed remotely on computers, phones and tablets. This component needs to have a DVR (Digital Video Recorder) which records the footage. Wireless cameras may use infra red or thermal imaging to operate. Wireless cameras could be installed both indoors and outdoors.

A wireless home security system is the amalgamation of the above mentioned components. Every component serves a specific purpose. An effective home security system depends on a number of factors. These include technology used in the components, location and their number. As the system is wireless, all components must be within the recommended range. Getting help from a security professional is recommended if installing for the first time.

Three Steps of a Wireless Security System

A wireless security system operates in a three-fold process:

Detection: This is the first step and includes the detection of a status change:
  • Someone broke a window
  • A door was opened by an untrustworthy party
  • Someone crossed the driveway without your notice
  • Someone came in through the attic
  • Someone tried to open a safe in the house
  • The smoke detector picked up signs of a fire in the house

Annunciation: This phase includes alarming the home owners of potential danger in or around their premises via the use of flashing lights, sirens, alarm systems, etc. With or without a monitoring service, this step is important, since it allows people in the house to move to a safe location until the authorities arrive.

Monitoring: This is certainly the most important aspect of the process. Your alarm system should ideally be connected to a monitoring service at the back end. In case of an emergency, when the system detects a threat and sounds the alarm, the monitoring company is notified. It is then their job to send  help. For instance, in case of a burglary, they will send the local police, in case of a fire, they will send the fire rescue team, and in case of injuries of casualties, they will send over a medical team as well.
