[UK] 2x POE cameras, software NVR

Please recommend POE cameras for my front and back gardens. Main security concern is the cars in the drive, directly below the camera (2 car side-by-side drive). Back garden is about 10m x 10m. Cameras will be mounted fairly low on the first floor, due to wiring. I have a linux home server so I’d like to use that as the NVR ideally, but failing that it can be installed on my desktop with the server for storage.
