You named it if you want quality. Many here go with cameras from trusted member @EMPIRETECANDY that sells Dahua OEM (so cheaper because you are not paying for the logo) at his Amazon store or website or direct.
Here is what you get from Reolink at night....
The invisible man, where can he be. Thank goodness he is carrying around a reflective plate to see where he is LOL (hint - the person is literally in the middle of the image at the end of the fence holding that big white rectangle LOL)
I've seen better images on an episode of ghost hunters
And of course, this is an example from Reolink's marketing videos - do you see a person in this picture...yes, there is a person in this picture.... Could this provide anything useful for the police other than the date and time something happened? Would this protect your home? The still picture looks great though except for the person and the blur of the vehicle... Will give you a hint - the person is in between the two visible columns trying to evade the cop car on the street:
Bad Boys
Bad Boys
Watcha gonna do
Watcha gonna do
When the camera can't see you
The first video was the E1 PTZ from a review video of the hundreds that are out there.
Here is the unofficial Reolink thread.
You can see all the attempts people have provided to demonstrate the quality of Reolink, and they are all a blurry mess at night or missing body parts or other messes.
We have challenged someone to provide a clean capture of someone moving at night with a Reolink and as you can see with 20 pages, nobody has yet to provide a usable image with motion at night.
Reolink's algorithm is designed to produce a nice bright static image at night and that comes at a cost of blur and ghost and missing body parts at night.

Thanks for the suggestions. Being new to the field of video surveillance, I had not considered the aspect of image quality at night and in particular the recognizability of moving subjects.
I did some research and it seems to me that the problem of subject recognition at night is a common problem with many video surveillance cameras.
In the case of Reolink it is certainly much more pronounced.
