These are very nice mounts and I had no trouble finding a pattern to match two makes of bullet cameras: Q-See and Ezviz both had symmetric matching patterns. The casings are nice quality and include the machine screws necessary to mount your camera as well as screws to attach the mount to your dwelling. I used these for a 4 camera POE security system. I took off one star for the following reasons: The hole in the center of the mount cover that allow the camera wires to enter the mount is not quite large enough in diameter to fit all RJ-45 female receptacles (see photo 1). The Q-See receptacle fit ok but the Ezviz receptacles were too large which required reducing the plastic corners of the receptacle using a Dremel tool until it would fit. The photo shows before and after using the Dremel on the receptacle.

The other issue is that the three holes for power/network ingress (two side and one bottom) are not threaded making it challenging to mate these with conventional conduit systems. In the US, either a 3/4" or 1/2" conduit connection is going to be the most common. The diameter of the ingress holes on the mounts are probably suitable for a 3/4" tap but without a professional machine shop, I would not want to attempt that. However, I found the following top hat grommets worked like a charm to allow a very snug fit using a 1/2" water tight PVC fitting: https://www.amazon.com/gp/product/B07M6B5BYZ/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1
Once inserted, the grommet can then be thread with a 1/2" fitting for a very snug connection. The second photo shows a mounted camera with a 1/2" water tight pvc fitting threaded using a grommet in a side mount hole.

Two last tips: there is less room inside the mount for extra wire than you might desire. For instance, I wanted to leave 2-3 feet of excess wire at the mounts to make it easier to finish the installation when it's time to crimp the connector on the ethernet cable and make the connection the the camera. This is especially desirable if you will be working on a ladder. Unfortunately, I was only able to get about 2 feet of excess Cat 6 wire to fit inside the mount along with the wire from the camera feeds crammed in as well - and that was a tight fit and difficult to accomplish at 20 feet above ground with both arms outstretched. The other tip: I recommend not using any strain relief on your ethernet cables at the mount point as this just makes the amount of linear space you need to accommodate the LAN connection to you camera receptacle longer and tighter to fit inside the mount - it also shifts the strain from the LAN side wires to the camera side wires which are typically more frail.

These universal camera junction mount boxes are great to have as installers. They have many hole sizes for different cameras with drilling additional holes. They are durable and thick to withstand all weather conditions. They also came with foam pads to protect against any damages to the wall surfaces. These juncture boxes came in packs of 4 which is value for money compared to other juncture boxes. I will buy more and recommend these boxes to others.

Junction boxes seem sturdy, weatherproof and they were easy to install. I used 4-inch diameter dome style cameras (see photo) on these boxes and it turned out well. I just needed to drill holes and tap threads on the cover plate for the four mounting screws.

These were easy to install and have stood the test of time. These are a great waterproof enclosure for exterior mounted IP cameras. They are made of solid metal powder coated exterior and there are rubber grommets and rings to keep the water out. Five stars across the board!

Great quality.easy to install and looks professional.
