I hear where you are coming from.....a) I'm not using an NVR. Rather a stand-alone POE+ switch b) It's an unmanaged switch so there are no port assignments as long as devices are plugged into one of the 12 POE+ ports and not the 12 non POE ports. c) I can use a short cable in ANY POE port and the camera is seen with the config that I initially threw on it.

I'm putting $10 on them not being terminated right, Id go ahead and re-terminate both ends and see what happens
I've seen cables pass a cheap tester, but be so bad that they don't work

Yup...We thought of that as well. Tried it with one of the long runs....Would pass info and packets to laptop but cannot recognize/initialize cameras.
At this point I think that it DOES need to be recabled though....Possibly I pulled the runs too tightly or somehow got a kink. But it just baffles me how I could have f'ed up all 5 runs....But it's a possiblity.
The switch will run the cameras on a short 7ft cable....Just not on my long runs....Tried a second POE+ switch as well. Same result

I wonder if the lighting up in the ceiling or other electronics they are using are creating interference that degrades the signal? testing with 250" of cable off the spool would determine that A. the cable is ok. and B. maybe EFI. Perhaps shielded cat5e?
this is a weird one.....I have a 5442, and 5241 z12 at 275'....
i'm running an 1100 watt power supply on a 24 port switch. i think the budget listed was 30 watts per channel.
looks like yours is 120 watt budget x 12 ports is only 10 watts per channel. the standard calls for 15 watts.

Is there a Russian Embassy across the street? 
are they using a Wireless barcode scanning network? is that cabling infrastucture or frequency possibly causing data corruption?

I wonder if there is a large voltage drop on the long cables either due to poor termination or other factor. I dont know what order a camera starts up in but perhaps its powering on its IR but not getting to the point where the OS has completed its boot because of some failsafe low voltage protection?
TCP/IP is an insanely forgiving protocol stack, its amazing how poorly a cable can be terminated and still function without drawing attention to itself untill higher utilisation occurs. You could run wireshark and see if you have a large amount of TCP retransmissions between your BI machine and your test laptop.
One other thing, you mentioned you have a patch panel. Is it a Keystone jack panel or the punchdown type?
If its keystone, have you tried taking the patch panel out of the equation and plugging the long cable direct into the switch?
Random ideas but i thought i'd trown them out there.

if data works with laptops, the cables should be fine. the camera uses poe af , so they only need 2 pairs. if these pairs would be damaged, then data should also not work.
you can try a poe injector (not a passive injector!) and if it also not work, then it should be a voltage drop problem. if they run with short cable on the switch, then its more obvious it is a voltage drop problem caused by the cable.
have you scratched one wire down if its real copper and not cca? i dont trust any ratings so i always do the scratch test before installing.
according to the spec sheet i dont see any clear statement if this cable is poe rated.
you should always hear a click on the camera if it is powering on (assuming that those are IR cameras)...

While not my favorite cable, I've used plenty of the Southwire stuff. Never had a problem, its real copper

The common denominator seems to be the cable plant, so either cable or connector problems. If it's Southwire, and real copper, I'd suspect termination problems. I've used a LOT of Southwire with no problems over the years.

What RJ45's did you use?
Are they spec'ed correctly to fit the cables diameters?

Did not see a response to this? Below shows the LGS124P switch LED's for the POE & non POE ports.
Ideally if the POE switches UI can display the metrics that would offer some insight.

I'm not sure what type of crimps and what type of crimping tool are you using but I'd recommend the pass through type. The others can be problematic.
Wire both ends 568b and if using the pass through type you can confirm wiring before crimping. See link
Note if you wire one end 568b and the other end 568a you will end up with a cross over cable. In this case the laptop will work but the camera won't. I stand to be corrected on this mind you.
With wiring terminations checked.
Disconnect everything and start with 1 camera only into the switch with a known good patch cable. Probably best to start with the camera with the shortest run first. You say this works fine using the psych cable but check, then re- mount the camera and plug into your installed cable. Plug the other end of this cable into the same switch port on the switch that you used with the known good patch cable. Check again
Concentrate on getting 1 cameras working before moving on to the others
good luck
edit I'm just realising you have checked with a tester so they shouldn't be crossed opps

Question to others
568b is the most common wiring method. Will IP cameras "just work" with 568a wiring as well?
