I had been under the assumption I was receiving a 5mp bullet cam, and direct upgrade to my current RLC-410 cameras I have. My plan was to simply unscrew the old, unplug, and plug in the new. When I opened the box, it was a dome RLC-422, not only was it a different camera than I had thought I was receiving, but on the side of the box it very clearly said it was a 4mp camera.
Not one to complain with a gift horse, I emailed Reolink support and asked to verify this was indeed a 5mp camera, as I wanted to give an honest review, they verified it was. More on this later.
So now I have the task of hanging a camera that is not only much bigger, but has a footprint in the realm of 3 times the size of my 410's. Due to the set-up of the wiring, I had to drill a new 3/4" hole in my soffit, as the hole for my 410 one wouldn't allow the 422 to fit, obviously I had to drill new holes for the mounting screws as well (4, as compared to 3 on the 410).
So I spent about 60-90 minutes hanging the camera. I will say, it's a nice looking camera, very discreet, and looks good where I put it. The color during the day is much more 'vivid' then my 410 models, it's especially noticeable on the grass. This particular model also has a 4 time optical zoom option, but once the camera is mounted, you cannot actually pan/tilt the lens, so if you want to use the zoom option, you have to adjust the camera so the area you want to zoom, is directly in the middle of the screen. Where I have this camera placed, using the zoom option is pretty useless, but it's an option you could use nonetheless. I do feel as though the angle of view is slightly wider on the 422 over the 410, and I do like this for where I have my camera.
The only problem I ran in to (so far) was a foggy dome. I hung the camera in the afternoon, around 2pm EST. It was good until the evening, when I noticed it has developed a rather serious case of fog when viewed. I read up on this and saw it's possibly the foam ring around the lens was dislodged, or maybe I was getting an IR halo effect from something near it. So I took my ladder back out climbed up, and sure enough there was a patch of fog directly over the lens, as well as above the lens. I pulled the dome off and cleaned it very well with a microfiber cloth, both inside and out, and was extremely careful re-installing the dome. Since I did that, I have not had any fog problems.
So, is it true 5mp? Honestly, I cannot tell, I don't feel as though the image is any sharper then my 410s, and you do not have the option to view the feed above 4k, that makes me question if these cameras are indeed 5mp, or if Reolink possibly over-extending themselves on the 5mp prototype, and sent out 4mp cameras to appease people.
So overall, I'm happy with the camera, but I'm slightly reserved about whether it's a true 5mp camera. The fogging issue was resolved easily, and may very well have been user install error. Also, if you plan to replace your 410 bullet cams with the 422 domes, plan accordingly, as you'll need to drill all new holes.
