An Introduction to Wireless Security Systems & Intrusion Detectors and Their Benefits

Wireless Security Systems & Intrusion Detectors and Their BenefitsWireless security systems are continuing to evolve and become more sophisticated. They are finding themselves installed in increasing numbers of homes in the UK and worldwide because people are attracted by the advantages and benefits they bring, especially for domestic applications. In this article we are going to discuss the how wireless systems work and how they differ from conventional wired alarms as well as their advantages (and potential disadvantages).

How Wireless Systems Function

Wireless burglar alarms are functionally similar to wired systems, only they lack the inclusion of wires to connect the various components together. The system will be made up of various detectors which communicate to a central control unit. These detectors could be for example:
  • Motion detectors
  • Smoke alarms
  • Carbon monoxide alarms
  • Force sensors
These are the standard sorts of detectors you would likely find in a security system. While smoke and carbon monoxide alarms are not necessarily for ‘security’ (i.e. intrusion detectors), they are often connected together as part of a single system. These detectors will transmit their signals to a control unit, which is the box you normally see attached to the wall within easy reach. These signals are transmitted using means such as infrared or radio.
Another part of the system which might be needed is wireless repeaters. The wireless signals transmitted by a wireless security system have a limited range and the signal needed by the control unit should be strong and clear. This means the signal might be too weak should the detectors be spread out over a large distance. Wireless repeaters act to strengthen the signal over a longer range, effectively taking a signal and boosting its amplitude, without losing signal quality.
The reason wireless systems are becoming so popular is their convenience and ease of use. The only wires that are sometimes required are wires to power the sensors - however, when sensors are used which use batteries, you can enjoy a truly wireless free system.

The main advantages include:

  1. Easy to install. Wireless systems don’t always need a professional for installation. Anyone with basic DIY knowledge can be capable of setting up their system. 
  2. Less disruption. With no wires, no changes or damage must be made to a home and it’s decor. 
  3. Modularity and flexibility. Wireless systems can be built on as time goes on, and due to a lack of wires, units and sensors can be repositioning when desired. 
  4. Portable. Wireless systems can go wherever you go, so if you move homes or change your business location, you can take the system with you and reinstall it in the new premises.
