A Sneak Peek At The Common Security System Components

As per the statistics, every 15 seconds, a burglary is committed in the United States, which means there are over 2.2 million burglaries every year. With the increasing rate of crimes involving break-ins and burglaries, it has become a necessity to install a security system to protect the family & property. However, before installing a security system effectively, you must be aware of the common components of a security system.

Common components of a security system

Control panel

Also known as a system controller, a control panel is often regarded as the ‘brain’ of the security system. It is usually placed inside a locked metal box and comes with a battery to provide power backup to the security system. The panel is connected to every detection device in your security system. When an intruder tries to break-in to your home, the sensors transmit the data to the panel, and the control panel, in return, communicates the information to the monitoring center. Some panels may include panic buttons dispatch authorities as well as communicate with emergency responders.


It gives an overview of your entire security system. The keypad is used to activate or deactivate the alarm.it can also be employed to determine which sensors are active & inactive. An advanced keypad can perform programming functions and also report past alarm histories. A keypad is generally placed near the entry or exit points. If required, a second keypad can be placed in the bedrooms to activate the alarm system while you sleep.


Security cameras are the core component of your security system. They can be both indoor as well as outdoor. Depending on your needs, it is placed in a strategic location across the home. The cameras, connected to the central system, record the video and send footage through a closed signal to monitor that displays the video. Security cameras are capable of capturing a wide range of views of the highest quality pictures & videos. They can also save the footage to the cloud for future purposes.

Door & window sensors

As the name suggests, these sensors are attached to your doors and windows. These devices employ two sensors: one attached to the window or door, and one on the frame. When the door or window closes, the sensors form a closed circuit. On the other hand, when the door or window opens, the loop breaks, triggering text alert or burglar alarms. Unlike others, these sensors are inexpensive.

Glass Break Detectors

This type of sensor lets you know an intruder is attempting to enter your home by breaking the glass on doors or windows. It works by detecting the frequency of the shattering sound glass makes and setting off an alarm. The detectors have a wide range in any direction, for an area of 25 feet. These can be placed near doors, windows, or other glass items and need not be pointed in one direction. Glass break detectors are inexpensive and can enhance security.

Motion sensors

This kind of sensor is an essential component of a security system. It intelligently detects motion and alerts you in the case of trespassers. These have a 90-degree coverage area and work best when installed in the corner of the room. In addition to protecting from burglary, the motion sensor finds its application in turning on/off indoor and outdoor lights, setting off alarms, activating security cameras, and many more.

Yard Signs and Window Stickers

Windows stickers and yard signs are often overlooked, but these are as essential as other security components. Their presence can discourage would-be burglars from entering your home.


Siren makes a loud noise to alert you or the trespassers that the alarm is triggered. If your security system is monitored, then a silent signal will be sent to the monitoring center to dispatch emergency responders.

Smoke detectors

The smoke detector provides comprehensive security to you and your family by detecting smoke and alerting the monitoring center about the same. The monitoring center will then dispatch the fire department for your rescue.

Carbon monoxide detector

It detects the level of odorless, colorless, and tasteless carbon monoxide. If the carbon monoxide crosses beyond the allowed level, the sensor alerts you and the monitoring center.

Given the advancement in technology, there are security systems with modern and upgradeable features. Check their specification before choosing the right fit for you.
