Gen power isn't Clean and may prove worse in the end but if you are using a Pure Sinewave Gen or a Power Cleaner Even a Good battery Backup could be used to clean out the Surge and Gap that a Generator power plant makes... There are some Computer Safe Generators the ones I know of are made by Honda and sometimes they can be Rented from your local Hardware rental store if you don't own your own... Not all Backup power system are Created equal and may not filter out all the issues over gen power...
Just something to think about
POE Camera Cat6 Cable Distance?

Be Safe.
Re: POE Camera Cat6 Cable Distance?
PCRC, you wrote "I would need to show the owner that the problem was the Cat6 cable and not the NVR / Camera..."
Perhaps this could help eventually.
CCA (copper clad aluminum) wire is not recommended for POE cables. Solid copper wires are. You could do some internet searches on it for more info. Webpage shows Sewell does sell some CCA cat6 cables. One way to check your cable is to strip off wire insulation and scratch it to see if the copper comes off and you see aluminum.

PCRC …
Unfortunately, those cheapo LED testers are simply doing continuity (resistance) measures, and pin-out order - they won’t test/reveal noise issues within the data wire pairs. More advanced ($$) testers will check for data quality. Again, since you’ve tested the runs are good via your LED tester from point A to pint B, the next logical test should be quality checks, which brings me to your next question . . .
In regards to proving bad cable to the home-owner, there are two ideas I can think of . . .
a) The more expensive (yet sure-shot definitive) way, is to invest in a high-end LAN cable tester. The kind that does quality, noise levels, and length reporting. If you think you’ll be doing more jobs – be a good investment.
b) A cheaper, more “creative” way . . . I’d buy your own CAT6 patch cord of the same (or longer) length than the suspect house run’s length. Like in any lab experiment, this cable is your known-good, or constant.
Now, either coil this new cable up right there next to the NVR and camera, or better-yet, actually run it outside/inside the house, to the remote camera actual location. Now swap/try both runs back and forth to see if the camera connects/powers-up correctly on each. Also "test" both runs with your LED tester. Say both runs test “good”, yet the camera only works with the new patch run. Demonstrated to any homeowner, having a logical-bone in their body, this should be self-evident the house wiring quality is suspect.
If both runs fail, we should not rule-in the house run being bad.
