I have upgraded my nvr to an Amcrest nvr. I have 3 1080p cams and 1 2k camera for the back door. This is a POE system. Here are some pics.
Like my cameras the higher pixel rate means a larger picture and not so much higher resolution. You can see that 2K cam on the lower right corner is a larger picture.Nice looking cameras. Is there noticeable difference between the 1080p and 2k cam.
That makes sense. 2k would be better if you had to zoom inLike my cameras the higher pixel rate means a larger picture and not so much higher resolution. You can see that 2K cam on the lower right corner is a larger picture.
BNC connectors are considerably more durable than RJ45 connectors (if you make them correctly). Both can suffer badly if the cable gets kinked or crushed. Outdoor grade RG58 has been available for many years and is relatively cheap. Proper outdoor Ethernet cable is no picnic to work with (although it is finally becoming easier to acquire). I'll be damned if I'm going to run conduit for a security camera.Bnc connection are bad just don't get those no wireless either.
Most run at 15fps or less.Is video cams runs at 60Fps or 120Fps?
It is a trade-off that almost nobody has been willing to endure because it doesn't really buy you much. A high frame rate doesn't make the bad guys any more recognizable. What the good guys typically want is a sharp still image; not more fps. PTZs (mechanical pan and zoom) are big here as they don't reduce the camera's resolution to capture distant bad guys.The higher the video frames rate the better to see the bad guys but of course it's eats up the hard drive spaces so there a trade off.
they compress it to h265 with backwards compatibility.Is video cams runs at 60Fps or 120Fps?

What do you mean by "backwards compatibility"?they compress it to h265 with backwards compatibility.
RJ45 connections and CAT6 cable in general are even more vulnerable so I'm not sure how Ethernet improves on BNC.My bnc connections caused problems in the rain.
I can't say I've ever seen a system that uses more than one BNC cable per camera. I have some PTZ cameras that use a BNC cable and a RS422 serial cable.I like the fact that I can run one cable instead of 2 for my camera.
Who is the "they" that you speak of? It is wrong to "phase out" something you haven't yet figured out how to replace.They are phasing out bnc and going to poe.
