3. Best for privacy: Eufy Video Doorbell 2K

We cannot tell a lie: this one almost made the top spot. Eufy’s newest doorknocker has the highest quality resolution of any doorbell on the market today and delivers a beautiful, crisp, clear picture. It works on a battery that it says will last 180 days (in our testing it was at 90 per cent after two weeks), so you can stick it anywhere you need to on your front door, making installation really simple (it can also be hardwired).

The killer feature is that it doesn’t rely on the cloud at all. Your video stays in your home on Eufy’s included HomeBase (which you plug into your router and also acts as an indoor chime). This means no subscription costs and no chance of anyone getting hold of your video from a cloud server.

But because it’s batterypowered (and even when wired) it suffers from the back-of-the head problem that plagues all similarly powered doorbells: it doesn’t always wake up in time to catch that person at your door before they walk away.
