The Ezviz Mini 360 Plus costs $80.
An Ezviz representative told me their products are available in the UK, but the distribution is limited; the Mini 360 Plus isn't currently available in Australia.
At the current exchange rate, $80 coverts to roughly £65/AU$105.
It has a 340-degree panning angle and an 80-degree tilting angle.
It also has opt-in motion tracking, meaning the camera is supposed to rotate to follow activity.
This feature worked fairly well when I was moving slowly, but wasn't able to keep up when I walked by at a faster pace.
You can power this camera over Wi-Fi or with an Ethernet cable; it also offers local and cloud storage.
It supports microSD cards up to 128GB.
