The UVC G3 Pro is the upgraded version of the UVC G3 in the Ubiquiti line of Unifi Video products. I won't go into the setup details, but it was found and adopted by my current Unifi NVR immediately, just like their other cameras. (These cameras require Unifi Video to run, which is a free download from Ubiquiti and they can operate in standalone mode or you can connect them to a physical server/NVR.) This POE camera can be mounted indoors and out, has built in IR for night time viewing and records in 1080p@ 30fps.Ubiquiti claims the UVC G3 Pro has a roughly 15% improvement in night time viewing over the standard UVC G3, even if you have the G3 equipped with the optional LED ring. I haven't been able to test this yet, but I will edit my review if I find otherwise. On this note, the optional LED ring will not fit the Pro model.The UVC-G3 Pro has a few other key improvements. One of the biggest features is the Pro offers a 3x optical zoom, controllable from the software and Unifi video app. There's no noticeable loss of quality when zoomed in, and this is a nice feature to have since Ubiquiti does not offer a PTZ camera.It also has a metal body compared to the plastic housing of the regular G3, and it is a bit heavier and quite a bit larger as well.I also noticed the rubber grommet they include inside the camera to keep water out has been improved and I like it a lot. To be fair I have never had issues with water getting past the old grommet, but they improved it anyway. Now when you have your cable coming out of the base mount for termination and you push the slack back into the wall so you can mount the camera, the grommet will stay securely put right up against the camera body to ensure a good seal. Before you had to remove the camera mount after pushing the cable in as far as you could and then try to push the grommet back into place to get that seal.The Pro is quite a bit more expensive than the standard G3 at this time, so if you need the 3x zoom and the claimed benefit of much improved night vision then go for the Pro. Otherwise you'll probably be just as happy with the standard G3. Most important to note is that unlike some of their other products, a POE injector is not included, so you must have a POE+ switch to power it (standard POE switches will not work).Lastly, someone asked if you could remove a standard G3 and leave the base mount in place and attach the new G3 Pro on the old base. Unfortunately the answer is no. Not only is the design different and the standard base will not work with the G3 Pro, but the G3 Pro base is actually wider; you can use one of the original screw holes where the standard base was mounted, but you'll have to spin the base a bit and put a new hole in to accommodate the 2nd screw. Kind of a pain, but that's what it is.All in all I like this camera, and they are still a good value for a quality security camera.
