I'm an end-user (with an IT background), not an integrator, but I can certainly understand that integrators are going up against each other all the time. Some customers will seriously look at (or be required to take) the lowest bid, without regard for what shortcomings there might be. I can also understand where some people with CCTV experience might not have an understanding of how Ethernet & IP works (the same can be said for sound experts, electricians, telecom professionals, etc). Many are now being put in a position where there's Ethernet cable somewhere in the job in lieu of what was traditionally being used. Some are very knowledgeable in the specs and best practices. On the other end of the spectrum, I've heard "well, we never have a problem with it and do it all the time".
In the case study linked above, there are unanswered questions, such as:
1. Are they using any supported PoE extenders? (The "proper" way to extend that signal)
2. Would Axis actually SUPPORT an end-to-end 850' run if they ran into issues?
3. To what extent will this cable manufacturer support what is truly a claim that it works outside of IEEE standards? Will they come in and fix things when it doesn't work? (I somehow HIGHLY doubt it)
I find the case study confusing & misleading. I also see a lot of possibilities for finger-pointing when something doesn't work. For example, if you have a switch issue and call the switch manufacturer for support, I'm pretty sure they're going to tell you to get it setup in a standards-compliant configuration before they'll even consider helping you.
As for the cable itself, I don't see how it's much different than anything tested here: https://ipvm.com/reports/test-long-ethernet (looks to be similar results)
As such, with a 47/53 split vote, I'm jumping to the conclusion some of the voters may not fully understand what issues can arise by going outside of Ethernet standards. I say this because I've seen it myself on multiple occasions.
Again, I completely understand that integrators deal with customer budgets, competitive bids, etc. That being said, however, hopefully these discussions help some of the members here to recognize and identify configurations with non-standard Ethernet links, and inform customer/end-user that a certain configurations "on the cheap" might not be the best idea for a reliable system.
