Security Systems: What are They and How Do They Work?

A security system is a network of sensors and other electrical components that work to detect intrusion inside an establishment. These systems can be found in both residential and commercial properties to protect them against burglary and/or property damage. Chances are you’re here to learn about security systems in general. What exactly are they and how do they work?

In today’s article we’ll be talking about security systems to help you understand how it can safeguard your property.

What is a security system?

In its most basic sense, a security system is a group of devices that aim to minimise the risk of intrusions and deter burglars from entering into a property. Multiple electronic devices are fitted inside the establishment like door and window sensors, motion detectors, security cameras, and a high-decibel alarm or siren.

How do security systems work?

Security systems revolve around the concept of securing all access points in a given facility. This includes doors, windows, rooftops, and any potential entry points for the burglar to break into. Sensors are installed in these areas and a motion detector is used to protect an open space. Here is how each component functions:

  • Control panel — The control panel is the brain of the security system where it is responsible for arming and disarming the sensors. It communicates with each device and sounds off the alarm in the event of a security breach. The control panel uses a touchpad where pass codes are entered to turn off alarms and allow for easy programming of devices.
  • Door and window sensors — These devices use two main components; the magnet and the reed switch. When in close proximity, they create a closed circuit. If one of them moves away (i.e. when a door opens), the alarm triggers. The reed switch attaches to the frame while the magnet is installed onto the door or the window.
  • Motion sensors — Motion sensors use an invisible light that protects an open space. If an intruder walks past it and blocks the light, the alarm sounds off. These devices are used around large spaces like the storage room, living room, garage, and more.
  • Surveillance cameras — Monitor the entry and exit points 24/7. Most security systems use IP cameras which have a higher resolution than the conventional analog camera. They also come with firmware updates to protect against hackers.
  • High-decibel alarms — Responsible for emitting a loud, prolonged sound that alerts the occupants and nearby people that a security zone has been breached.

Security companies often provide their clients with yard signs and window stickers to alert thieves and burglars that the establishment is protected. This can serve as a deterrent for the burglars to think twice about breaking inside the property.

How a security system can protect you during an intrusion

Security systems are designed to facilitate swift action in the event of an intrusion. How a security system can protect you will depend on what type of system is installed in your property.

Professionally monitored security systems

If you have a professionally monitored security system installed, the alarm monitoring company will be notified whenever an alarm triggers inside your home. The control panel will send signals to the ARC (alarm receiving centre) where they will interpret these signals and attempt to make contact with you. They will attempt to communicate with you via 2-way voice communication or through dialing the emergency contact number on your account.

This type of security system communicate with the alarm monitoring company in a number of different ways:

  • Through existing phone lines which will work even during a power outage.
  • Through cellular radio frequencies (wireless).
  • Voice over Internet Protocol (VoIP) which requires power to work.
  • Via the Internet.

The alarm monitoring company will verify if your security has been breached and will send over the appropriate authorities to respond to your property.

Do-it-yourself security systems (DIY)

Many security companies are offering DIY security system packages which allow a high degree of customizability. The only downside is that you’re on your own in the event of a break-in. You will need to contact the proper authorities to respond to your situation (which can be difficult under certain circumstances). You’re also responsible for installing all the sensors and motion detectors correctly and ensure they work properly.

While DIY security systems are more affordable, we recommend going with the professionally monitored security system for an enhanced level of protection.

The advantages of installing a security system

Homes without security systems are more likely to be targeted by burglars than those that have one installed. Criminals are always on the lookout for properties that are easiest to target and if they see that an establishment isn’t protected, they take action immediately. Security systems serve as an effective deterrent for burglars because it increases their risk of getting caught, something they definitely want to avoid.

Another advantage of security systems is that it provides you with peace of mind. You can manage your sensors remotely via a smartphone app that’s connected to the internet. With just the tap of a button, you can activate the sensors even if you’re away from your home. Lastly, insurance companies are willing to reduce their premiums if they know that you have a security system in place.

Security systems are undoubtedly a must in today’s age and you’re doing yourself a disservice if your property doesn’t have one installed. Your home is one of your biggest assets and it makes sense to provide it with the level of protection it needs. Consider having a security system installed to better protect your property and your valuables from the hands of criminals.
