Home Security: Wired vs. Wireless

While the general assumption these days is that wires are messy and complicated relics of a bygone era there may still be some perks for wired systems when it comes to home security. There is a bit of a divide in the home security sector as to which is better: wired or wireless? Each has its merits and shortcomings so there’s no clear victor past one’s own opinion. However, if you’re looking into a new security system and haven’t yet made up your mind this is very likely a question you’ll have to ask yourself: which is the right choice for you and your home? Here we’ll look at some of the pros and cons of wired vs. wireless home security systems.

Cost and Installation

Hardwired security systems are usually cheaper than the wireless counterpart but require a lot more effort to install. A typical hardwired home security system can take over 10 hours to install (for a manual install) and will require some drilling in your home’s walls. On the other hand, a wireless system is generally more expensive (though this might be changing soon) but much quicker and easier to install. If you plan on installing the system by yourself this may be a big factor that you can work into the price. There is a bit of variance here because some houses will be easier to install a hardwired system than others. One additional perk of wireless security systems is that if you are planning to move in the near future you can relatively easily bring your security system with you unlike with a hardwired system.


In recent years wireless systems have made a lot of improvements to close the gap in performance with wired systems. The fact remains, however, that with a wireless system you are susceptible to interference and other technological woes. Most wireless systems require battery operated receivers that need to remain powered or else the system will not function. In terms of security both systems do well and this will vary mostly on the quality and brand of the system. However, there are fewer methods to disable a hardwired system than its wireless counterpart. Underwriter’s Laboratory (a notorious security review panel) hypes wired system for extreme security situations. That being said, however, wireless systems will likely work for most residential purposes. The difference is quite small as long as you aren’t guarding Ft. Knox. Each has its pros and cons so the choice is yours.
