The Reolink RLC-520A is a great camera, unfortunately, they're mounted vertically. I wanted to mount mine to a wall. Additionally, I wanted to secure the plugs, and so made space in the mount to squeeze them in (it's a tight fit).
Requires M4 x 8mm bolts to mount the camera. Captive threading was added to the print, but I did need to warm up a bolt with a lighter to help make the thread usable.

Finally, I also made a separate make which is cable organiser clips for CAT5e cable that helps keep things neat. It can be found here:
