Protect a home and its contents when carrying out building works with various types of testing equipment. For example, there are electronic detectors that help locate power cables, gas pipes, and wood and metal studs, identifying a safe drilling point into a wall. There are also wireless security cameras that can be connected to a smart phone, allowing homeowners to keep tabs on their home when away at work or on holiday. Smoke and carbon monoxide alarms also help keep a property safe and come with pathlights to guide the way to the exit in the dark. With many of these products, there is a choice between wired or battery-powered versions to suit any requirements.
