Wireless Alarm Systems vs Wired: Which Is the Better Choice?

You may think that there isn’t many differences between a wireless alarm system and a wired one, but that’s where you’re wrong! Check out this article to help you decide what type of alarm system is right for you!

Wireless Alarm

According to the Office for National Statistics, theft offences within a dwelling have remained stable since the 1980s, although burglary rates across England and Wales have sharply declined. Unfortunately, this isn’t the case for every location.

Facts from the Metropolitan Police show a 21 percent rise in burglaries year on year, and “hotspots” are increasing.

Consequently, more citizens are turning to personal security systems to keep their valuables safe. Their pursuits lead them to a crossroads where they must decide between a wireless alarm system and a wired one.

If you’re standing at your own crossroads, this article is for you. Here, we’ll discuss the benefits and disadvantages of each so you can decide which system is appropriate for you.

Wired Alarms

Wired alarms utilise wires hidden throughout a house. The wires transmit signals between the security devices and the control panel.

The control box monitors the alarm circuits, sounding the alarm when opened, closed or disturbed. The alarm turns off when someone enters a security code into the keyboard.


Wired systems contain several advantages over their wireless cousins.


Due to the precarious nature of radio waves, wired alarms are more reliable than wireless systems. The communication process contains no batteries, electromagnetic signals or other hazards that create false alarms or faulty systems.

However, advancements in wireless technology closed the gap that existed between the two. Today, reliability issues in wireless systems are rare.


Wired systems require little to no maintenance. Once the security is in place, homeowners need only check it for routine upkeep.

Inspect the individual components to ensure they work properly and take advantage of the control panel’s “test” option. It will run a self-diagnostic on the system, although owners should contact their monitoring service to forewarn them of the test.

Aside from these expectations, homeowners have little to do.


Wired systems provide adequate coverage for large dwellings. Many provide security up to 300 metres from the control panel to the sensor. Wireless systems have half the coverage.


If a homeowner has a wired system and decides to upgrade it, the process is easy. Because the wires already exist, the new system is simply installed to replace the old one.

Further, new technology oftentimes works with older models, making worries about upgrading unnecessary.


Finding replacement parts for wire systems is easy, as many devices are compatible with multiple systems. Consequently, it means shopping for replacement parts is easier.


Prices for the monitoring system are less expensive than their wireless counterparts. With that said, installation is costly.


While wired alarms have several distinct advantages, homeowners must also contemplate disadvantages.


For a wired alarm to function, a landline is necessary. Through this landline, communication and alerts occur.

As of 2017, 89 percent of UK citizens had a landline in their abode. However, the common use of cellular devices is dwindling the number of houses with this option.


Installation requires running wires throughout the walls, ceiling, and floors. Therefore, drilling holes within the home is necessary.


The installation itself is difficult, frequently requiring professionals. Further, it is an added expense.

Wireless Alarms

Wireless alarms use sensors throughout the home that communicate with the central control panel through radio frequency. Outbound communication is established through a cellular uplink. If the owner prefers, landlines work as well.


Many consumers prefer wireless because of the convenient features it offers.

Ease of Installation

Many systems get installed by the purchaser himself. In fact, installation is achievable in mere hours with the proper preparations.


Users are not limited by wiring, making the system versatile. It is usable anywhere a homeowner finds it ideal within the house, although the control centre must be within a certain range of the sensors.


Moving house? If so, you won’t have to leave your system behind. Wireless alarms are simple to remove and re-install elsewhere.

With studies indicating citizens move at least three times before reaching 45 years, this is a beneficial feature.


The majority of the UK population below 35 rent. Wireless systems do not require the holes associated with wiring. Less damage happens on a property, making it ideal for renters.

Easy Upgrades

New devices need to get synced to the control panel. In wired alarms, extra devices need further wiring.


The convenience wireless home alarm systems provide is its distinguishing characteristic. However, individuals considering wireless should take its disadvantages into account.

Electromagnetic Interference

Wireless communication relies on frequencies within the electromagnetic spectrum. As a result, interference from other devices affecting the spectrum may boggle a wireless alarm.

Advancements make these scenarios rare, but it is a factor all purchasers should consider.

Structural Interference

As electromagnetic interruptions occur, structural interference may also impact wireless communications.

Concrete, mirrors, metal, and water sometimes obstruct the system’s transmission path.


Wireless sensors depend on batteries. While lithium batteries last for years, others require frequent replacement. It is up to owners to check and replace batteries.

Replacement Parts

The fast pace at which technology grows makes it difficult to find replacements for old systems. Unfortunately, this may mean an owner must buy a new alarm system from time to time.

Less Coverage

Usually, the 150 metres many wireless systems offer in coverage suffices. However, for consumers with large houses, this may pose an issue.

Repeaters add further coverage, but the additional cost deters some.

For citizens with grandiose estates, the limitation on devices may prove problematic. Most wireless alarms can only maintain 40 or 50 devices.

Which Will You Choose?

Choosing between a wireless alarm and a wired system requires analysing your personal circumstances.

Wired alarms offer solid reliability but come with pricey and invasive installation. Wireless systems are convenient but may experience interference.
