Nice looking cameras. Is there noticeable difference between the 1080p and 2k cam.
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.
That makes sense. 2k would be better if you had to zoom in
This is great. I’m considering putting in a POE system with cameras mounted under eaves. Run wires thru the attic to a hidden NVR.
Do you recommend Amcrest exclusively or are there other brands I should consider? Camera brands/models I should consider?
I am deciding between an 8 and a 16 port system.

Not that it has anything to do with FTA, but I recommend using cameras that send digital pictures rather than a scanned sequence of lines.
Not all high resolution cameras are digital. Analog systems exist to get those with old cabling going with higher resolutions but if you're starting from scratch, there's no point (unless you're one of those that likes to use legacy switchgear and LNBs just because they're "cheaper").

Poe is the way to go. Amcrest is made by the same company from China like lorax. YouTube videos are great to get info. I like the build quality of amcrest. I turned off my night vision for my parking lot cam and it's nice. My back door cam has speaker and mic so I can scare the cat. These cams ip cams I had a AHD cama that stinks compared to this. Bnc connection are bad just don't get those no wireless either.
Using mostly Dahua POE cameras here, they seem to work well down to -40. Have had some Foscams (Armcrest), moved them indoors in outbuildings.etc due to moisture ingress. They are ok if on a budget unless they have improved them. Have 9 cams around the yard (big area). Nice to check things out when away. Using Blue Iris software to run them.
Is video cams runs at 60Fps or 120Fps?
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.

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.
I don't recommend BNC (I'm not a fan of SDI), but I can't abide someone accusing it of something it isn't guilty of.
Most run at 15fps or less.
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.
My bnc connections caused problems in the rain. I like the fact that I can run one cable instead of 2 for my camera. They are phasing out bnc and going to poe.
they compress it to h265 with backwards compatibility.Is video cams runs at 60Fps or 120Fps?

Mine are all set for 15fps. Either H265 or H264 depending on camera age/firmware. Mostly use cat6e stp cable to minimize voltage drop (23ga as opposed to 24), not much run exposed. Ubiquiti A/P at the house and 2 remote sites with small POE switches to power the cams, and some underground cable runs for distribution.
This is a shot from one of the cams with a variable zoom, zoomed all the way out. Catches traffic coming in/out of one of the driveways.

What do you mean by "backwards compatibility"?
While the new compression technologies offer significantly better storage efficiency, they make finding your way through the captured images a lot harder.
RJ45 connections and CAT6 cable in general are even more vulnerable so I'm not sure how Ethernet improves on BNC.
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.
Who is the "they" that you speak of? It is wrong to "phase out" something you haven't yet figured out how to replace.
The problem with Ethernet is that it is distance limited. It isn't a problem in most residential situations but not being able to go past 150' or so due to POE limitations (using 24VDC) is a serious problem that coax doesn't typically suffer. The 100m Ethernet data distance limit can be overcome with fiber but fiber can't support POE.
Sounds like for my internal wall and attic runs, Ethernet cable should be just fine.

I have 3 wireless Amcrest cameras no NRV, I use Blue Iris which is software-based. This camera is used for weather conditions on my website the other 2 are indoor security. I prefer Hikvision POE but with new house decided to try wireless. I'll be adding 1 more this winter for a snow stake cam, visitors love.
