If you're looking for increased protection, the best monitored alarm systems are for you. Offering more comprehensive security coverage compared to standard home security systems, they offer 24/7 professional monitoring of your property on top of general security and surveillance hardware.

Where standard home protection will simply sound an alarm to alert nearby people, in the hope that someone will investigate or call the police, or perhaps scare off intruders, the best monitored alarm systems will alert a support team when triggered, and they can then ring the police, and that coverage is offered 24/7.

Of course, this level of protection does involve additional investment. Along with paying a subscription for the support team, you'll usually need to pay for professional installation as well.

However, if you want to protect your home or business, this extra level of security is well worth the cost. In this list, we've picked the best monitored alarm systems that offer excellent value for money, and which often include professional installation as part of the price. Picking any of the solutions on this page will give you the very best protection for your home or office.

Other monitoring alarm systems to consider

While we've feature some of the major providers of monitored alarm systems, there's also a growing number of alarm systems that you can set up at home and add monitoring to as an additional service. Here we'll look at some of those services, not least because the overall price can often be cheaper than dedicated monitoring solutions, not least because of the easy set up and install of the equipment yourself.

SimpliSafe offers a really simple home security solution, centered on a single base station which can be expanded out to cover a wider area, indoors and outdoors, using a range of additional sensors. Once you've bought the Simplisafe security kit you need, you can either monitor it all yourself, which is easily done, or else sign up to SimpliSafe's 24/7 monitoring, with no contract.

Scout is another option if you want to build your own home security system simply and effectively, using a range of sensors working with a base station for monitoring purposes. Like a lot of similar systems, while you can monitor everything yourself, there is a 24/7 professional monitoring service available, with additional camera and cloud storage options for your video recordings as well.
