How Does a Security Alarm Work?

How Does a Security Alarm Work?

A security alarm is composed of several parts which are needed to provide complete security monitoring for your home and your office. All the parts of this system is wired or connected to a central control where the user can make adjustments on the different settings as well as manage saved files and program scheduled monitoring.

A simple security alarm works by simply activating the alarm; a simple system is composed of a sensor or a switch which is wired to a noisy alarm. When an intruder activates the alarm either by opening a door, breaking a window or tripping a wire, the alarm goes off automatically. This simple process is still being used in modern and updated systems however there are several modifications and additional features to help provide better and more effective security.

Security alarm – the alarm is not just wired to a sensor or switch but is also connected to a system that automatically contacts the local police or fire department in case of fire. Security alarms are connected to windows, doors, gates, garage doors and in areas where there are possible break-ins.

Security cameras – these are integral part of modern security systems. There can be one, two, three or more camera systems in a home or business establishments and these are setup in places where there is a possibility of illegal entry. Security cameras may have night vision capabilities, motion sensors, IP network monitoring (to view your recordings or live footage from an online site), pan and tilt options and automatic video adjustment settings. There are outdoor cameras with tough protective outer casings and strong weatherproof brackets while there are also indoor cameras of different size,s shape and lens type.
Security cameras are connected to recording device like a DVR, a VHS recorder or a hard drive to record long videos and even 24/7. There are also recording systems that will only record when a sensor is activated.

Sensors – there are different sensors that may be found in a complete security system and these may depend on the kind of environment you have as well as the type of business you have. Sensors may either be heat sensors, smoke detectors, glass break sensors, door and window sensors, flood sensors, motion sensors, carbon monoxide sensors, freeze sensors, garage door sensors or recessed door sensors. Some security systems allow the user to choose or to personalize his own system for his home or business.


Remote control or control panel – convenience is the most important factor in updated security systems. 
Most now have a central panel or remote control where you can access all the features of the system and make the necessary changes or adjustments as the need arises. For example, programming the system to text or email you for any emergency is your option when you are away but upon arriving you may set the system to call your partner or your mother in case of an emergency even when you are at home.
