How smart home security systems work

Smart home security systems combine traditional burglar alarms with apps used on smartphones, tablets and computers.
Combining alarms with apps allows users to monitor, control and interact with their security systems remotely.
These home security systems themselves have become increasingly 'smart', using the internet to connect hardware devices like cameras, motion detectors and door locks without the need for wires.
Various devices can be bundled together to create off-the-shelf kits or they can be set up by a professional home security installer to provide bespoke configurations tailored to the exact needs of the client.
Bundled kits will vary between brands, but manufacturers will usually offer a basic core system with options to add extra gadgets and increase facilities as and when they are required.
Whether bundled or bespoke, all smart home security systems are controlled through a central hub that connects the various components wirelessly through the internet.
Once set up and configured, an app downloaded to a smartphone or computer, will let you monitor and control your own network. The app will let you access security cameras, store and view video footage, receive alerts and so on.
More sophisticated systems have options to control such things as home heating and lighting or to interact with home appliances like fridges or ovens.
The latest modern smart systems do even more. Often called home monitoring kits they can include such things as night vision cameras for baby monitoring, moisture sensors in bathrooms, controls for TV, radio and sound systems, or even pet tracking with GPS.
You can control door locks, security gates, internal and external lights, room thermostats, vacuums, lawnmowers, and even pet feeders with the right smart system and an installed app.

How much does smart home security cost?

Prices vary a great deal, depending on the number of gadgets included in the system and the control systems you require. Basic off-the-shelf smart home security systems can cost around £200. Higher-priced systems not only include more built-in features but also allow you to add more devices later, such as smoke alarms or panic buttons. Many now boast compatibility with other systems such as smart speakers and smart lightbulbs.
Costs increase along with the added gadgets and features. A smart home security system to cover a normal house, with motion detectors will probably cost more than £500.
Take care in choosing though as some systems are incompatible with add-ons from different brands. All systems have a central hub connected to a broadband router but they signal to components in different ways. Proprietary signalling offers greater security but usually means you are tied to a single brand's gadgets.
Add-on devices can include security cameras, motion sensors, smart plugs, opening alarms, tag trackers, sirens and much more. Each system will have its own app so you will need a smartphone or tablet to connect up and control the whole system.

Choosing a smart security system

There are many factors to consider in choosing a smart home security system. Basic smart systems are relatively cheap and easy to install but experts agree that basic bundled packages are unlikely to offer the level of protection needed in most homes.
If you do opt for a DIY approach be open to adding extra sensors to the basic bundle and make sure the whole home is covered. Buying extra doors and window sensors will push up the price but may, in the end, be well worth the extra.
Manufacturers offer a wide variety of systems and, with so many add-ons and extras, working out the best system for your property can be very confusing.
Some makers place the emphasis on video surveillance, with HD cameras to detect motion and automatic recording, while others make a feature of fast response times from a 24-7 monitoring centre.
Expert advice is to favour smart systems that include an outdoor siren, even if it's a dummy one, as visual alarms remain a strong deterrent to burglars. Other things to look out for include a decent wi-fi range, a battery back-up system and compatibility with phone operating systems and third-party components.

Professional installation or DIY?

Most bundled home security kits boast how easy they are to install and configure. However, checks by independent security experts find that the great majority of do-it-yourself installations leave a lot to be desired. Components such as security cameras and motion detectors are often installed in the wrong place and turn out to be less effective than promised.
Manufacturers provide relatively little guidance on where to place devices to maximise their effectiveness. Security cameras, for example, should not be placed facing windows as figures are thrown into shadow by bright background lighting.
Motion detectors are ineffectual if they are easily spotted and avoided or if they can be moved out of position.
A professional smart home security installer will make sure all components of a smart home security system work in harmony and are best placed and configured to make maximum use of their functionality.
Make sure your installer has NSI accreditation as this ensure that products and companies meet or exceed security industry standards. A gold-level certification from NSI delivers the best value across industry and is supported by police, fire, rescue services and insurers.

Smart system or traditional burglar alarm?

There are pros and cons with choosing to adopt a smart home security system or stick with traditional alarms. Both systems are perfectly good at providing protection against break-ins.
The advantages of installing a DIY smart system yourself are offset by the lack of expertise in placing component where they are most effective and ensuring they all work well with each other.
Traditional burglar alarms have the advantage of very high-security standards and professional installation but they can come with costly overheads in terms of monitoring contracts and regular maintenance checks.
It really depends on which is the best system for you. If you are tech-savvy and prepared to accept some basic protection in the home, a bundled DIY kit may be just the thing. If you are more security conscious you may prefer the professional installation of a smart home security system or a traditional purpose-designed burglar alarm system
