Criminals can beat your burglar alarm

The Mail on Sunday purchased the YARD Stick One from Amazon and also bought a £149.99 ERA miGuard Wi-Fi alarm system from electronics store Maplin in order to carry out tests.

Ken Munro advises that: ‘Manufacturers should upgrade their security so this doesn’t happen. Consumers should look for “two-way” systems, which means the alarms can detect jamming attacks like this one.’
