The Difference Between Wired & Wireless Intruder Alarms

The Difference Between Wired & Wireless Intruder Alarms

If you are considering the installation of an intruder alarm system for your business, you are probably aware that you can have a wired or a wireless system. However, you may not have thought about the advantages and disadvantages of each. As NSI Gold Alarm Installers we have the skill to help you to make the right decision for your premises.

Difference between Wired and Wireless Intruder Alarms – Installation

One of the first things to consider is the cost of installation in the first place. If you are starting from scratch with a new build, incorporating a wired system into the original plans is easy. However, if you are installing a wired system into an existing property, this usually involves drilling holes in walls, running cables around doors or windows, or hiding them in plastic trunking which also has to be installed. Whereas wireless systems are fast and hassle-free.

A wireless burglar alarm system can usually be installed in less than a day, which reduces the installation cost.

Note that if you own a business with suspended ceilings or cable trays in place, the labour element will be reduced, because it is just a matter of running cables into pre-existing holes and positions.


For a wired system, you also have the problem of aesthetics. Do you really want holes drilled in walls and ceilings, where you may have to do a spot of re-decoration afterwards, cables around the doors or windows, or plastic trunking, which can never be described as attractive?

It used to be the case that wireless systems had the reputation of causing false alarms. However, these days they have caught up and there is really no difference between the two from a reliability point of view.

Running Costs For A Business

As far as running costs go, wireless will be a little more expensive, but not disproportionately so. You will need to change the batteries every two years, and the cost will depend on how many detection devices you have, but it is not normally a lot. It is also the case that replacement parts for a wireless system cost more than for a wired system, but all our parts come with a one year guarantee in any case.


A further consideration is the flexibility of the system. If you need to add an additional detector or two, with a wireless system it is a very simple matter. With a wired system, you have to take the wiring into consideration, whereas with a wireless one it is just a matter of installing the detector and programming it into the system.

Furthermore, a wireless detector can be placed in the optimum position. For a wired system, you may decide that you do not want a cable running around the room to the far corner, and opt for installing it in the corner nearest to the panel, which may not be the best place to put it from an operational standpoint.
