A practical comparison method

We shortlist five products for each roundup and compare their published specifications, intended use, access method, installation requirements and likely fit in a real UK home or workplace.

The editorial copy is written as a buying aid, not a manufacturer endorsement. We do not treat a high price or a long feature list as a reason to recommend a product on its own.

Product data, prices, stock, delivery information and images can change. Always confirm the live retailer listing and the manufacturer instructions before ordering or installing security equipment.
