BLINK

There are very few completely wireless cameras out there, but Blink is the best, in our opinion. With pure battery power, you can place one anywhere in the home, and it’ll go for up to two years without having to replace the batteries. This doesn’t mean Blink is lacking powerful features, because you get niceties such as crisp 1080p video recording, motion detection alerts, night vision and much more. £129.99, blinkforhome.co.uk
