Ring Video Doorbell 4 £139.99, en-uk.ring.com

Ring (owned by Amazon) has been making doorbells for a decade now and the Ring Doorbell 4 is its most recent model. Compared to brands like Google Nest or Arlo, the Ring doorbell isn't the most aesthetic option, offering as it does a purely utilitarian design.

However, what you lose in design, you gain in a long list of features. The Ring has a fantastic battery life, lasting for up to six months at a time from an 8-hour charge. Equally, the camera produces clear audio and video both in the day and night. There are options to detect packages, leave pre-recorded messages, interact with people at the door and even set up a threat deterrent when you go away. While some of these features are locked behind a subscription plan, the Ring doorbell is still a more than capable device without this 'paid-for-content'.

Google Nest Pro Doorbell

£179.99, Store.google.com 

The Google Nest Pro Doorbell features a 145º field-of-view, streams in 1600p HD-resolution video and displays footage in a 3:4 aspect ratio, ideal for viewing on a smartphone held vertically.
