Some security devices can ward off criminals with a siren and a floodlight, others - like internal and external security cameras - often activate when they sense movement. So, if there's anything untoward happening in your home, your camera should pick it up and alert you.

It’s always a good idea to invest in more security for your home.

Some security devices can ward off criminals with a siren and a floodlight.

Others – like internal and external security cameras – often activate when they sense movement. So, if there’s anything untoward happening in your home, your camera should pick it up and alert you.

Stocking up on security can sometimes mean a reduction in home insurance premiums too. It’s reassuring for insurers to know that you’re taking steps to keep your home secure.

Here’s what you need to know about home security cameras, along with a few models that could help build your home surveillance system.

What should I think about when getting home security?

First consider what you want the device to do. Do you want the inside and outside of your house monitored? Or both? Do you need a camera or would an alarm system work?

For the best surveillance, you should also make sure the device you choose has some of these features:

  • Night vision

  • High-quality video recording

  • Two-way audio recording

  • Motion detection

  • A user-friendly app

  • Plenty of storage.


What are wireless home security systems?

Most wireless security kits come with a control panel, cameras and motion sensors. But if this isn’t enough, you can always add other components to your security arsenal.

Wireless security systems are usually battery powered with a network of sensors that send messages to the control panel via radio frequency.

The control panel then sends an alert to you if there’s something happening in your home that shouldn’t be. It does all this ‘wirelessly’, either through your WIFI, or phone network.

Wireless systems are often straightforward to install as you don’t have to conceal any wires. It could mean a potential saving as you may not have to pay for professional installation.

This makes most wireless devices easy to uninstall too. Handy if you decide to move.

Although there are many upsides to the wireless system, the cost might start to mount up when you factor in batteries.

You’ll have to get these for the control panel, cameras and any other device on your network.

That said, certain RING security devices come with rechargeable batteries. And Amazon claims the battery in their Blink device lasts for up to two years. Both these models are featured below.

It’s worth investigating to see what’s available.


What are wired home security systems?

As the name suggests, wired home security devices are hardwired into your home.

If you have multiple wired security devices they’ll connect to each other through wires – rather than the radio frequency which is used by the wireless system.

The wired device will connect to the outside world – either you or your security company – through your landline.

They have to be professionally installed, as the wires have to be concealed within the walls of your home.

This makes wired systems less easy to take with you if you decide to move.

Most security systems on the market now combine the two.

You could opt for either a wireless security system that connects to a landline and phone network – or choose a wired device that use a phone network to communicate with you or your security company, rather than a landline.


Where is the footage from home security systems stored?

The footage for both systems is either stored on an SD card, an external drive or online in the cloud.

There are a couple of drawbacks to both.

If you store the footage on the SD card or drive, criminals could take the device, along with the footage. 

The upside of this type of storage is that it’s just a one-off payment for the card or drive.

If you’re storing footage in the cloud it could be vulnerable to hackers. But you will still have access to the footage if your camera gets stolen.

Sometimes cloud storage comes free. If not, you may have to pay a monthly fee – up to £10 a month in some cases.

One of the upsides to cloud storage though is that there are ways to at least minimise the risk of hacking. 

For example:

  • Upgrade the security system for your device

  • Make sure logins and passwords are secure and regularly changed

  • Use wireless encryption so no one can see what your camera sees via the internet.


How much do security systems cost per month?

You pay for most security devices up front, without having to pay a subscription fee.

However, most manufacturers will offer extra features for a monthly fee.

For example, when you buy a RING device, you have features for free, such as:

  • 1-year limited warranty
  •  Motion-activated notifications
  • Real-time video with Live View
  • Two-way talk
  • Theft protection.

They have two extra packages that you will have to pay for though, these are Protect Basic and Protect Plus.

Protect Basic is just £2.50 per month. Some of the features it includes are:

  • 30-day video history
  •  Video saving and sharing Snapshot capture.

Protect Plus is £8 per month. You get all the features of the free and basic package, plus extended warranties for all RING devices and discounts on their website. You can find the full list of features on the RING website.

The same applies for Swann security systems. You can use the product without having a subscription, but for extra security you can sign up to Swann’s secure plus plan.

This has two tiers: The ExtraSecurity Plan and CompleteSecurity Plan, which cost £4.95 and £12.95 a month respectively.
