Security

A £7 door sensor that works well in his gaming cabinet automation.

A stupidly extra but impressive $700 smart lock with 10 unlock methods, including palm vein, rated 9 out of 10.

More a Roomba with CCTV than a relationship device; better than expected but he still wouldn't buy one.

Clearly the better doorbell, with a field of view about twice the fake's and a much smoother frame rate.

Does the job but is fiddly, expensive for a door handle, and has cheap-feeling LEDs; 6 out of 10.

An autonomous security robot packed with sensors that ran over a toddler, was knocked over by a drunk man and drowned itself in a fountain.

Rated 5 out of 10 fail: crammed-in tech caused overheating and swelling batteries in 488 reports.

Some doorbells spontaneously caught fire, which he called a horrendous oversight, though fixed with an update.

Cameras protected only by a simple password were hacked, with families threatened and blackmailed.

A tiny 1080p camera with ten infrared lights for night use and motion alerts to your phone.

Clever two-in-one smart bulb and IP camera that saves money, though weak in low light.
