We've rated two types of burglar alarms. The first are monitored by the company and you pay an annual or monthly fee for this service. The company will then call you or alert the police if the burglar alarm goes off.
The second type are bells-only or those that auto-dial you if there's a break-in. These don't come with a contract and can often be bought from DIY shops.
