We might be wrong, but it feels like 2018 could be the year of the video doorbell. Once you’ve used your phone to cunningly avoid a mustachioed door-to-door insurance salesman, there’s just no going back to dumb bells. Price remains an issue for a lot of consumers, though, which is why the Blink Video Doorbell could give the market a bit of a shake-up. Existing Blink customers can pick up the device for $99 (around £74), while the starter kit will set you back $129.99 (around £97). Either way, that’s a smart doorbell with two-way audio, motion detection, night vision and a live view HD stream for less than £100. It’s also water-resistant, which is pretty important considering the near permanent raincloud that hovers over this here island. There’s no word on a UK release date yet, though. Hopefully we'll get an update at CES.
