Yes, one of them (noname PTZ) is detected by Dahua's Configtool as .22.26 but picked up by BI as 22.78. When weird behavior happens, it happens to me first.I thought it might be useful with your issue - to ID the mac addresses of the cameras with the IP's the DHCP was handing out to them, since in one case I think you indicated you were finding conflicting IP's associated with a single camera.

There is a lingering "but what about...' ONE of the 'bench' cams was the first to fail and it actually was running on the other (8port) switch in the shop....hmmmmm. The other two cams on that switch and the PTZ that replaced this cam are working fine. The PTZ is externally powered.
Looks like I'm in the market for a 24 port PoE --with gigabit uplink would be handy--. Recommendations appreciated. From other threads the IPCP-24P2G-AF2 was talked about, but no one has one. The UNV model at Nelly's is over a grand...
Do I need to learn about Cisco? Do the cisco managed switches work fine UNmanaged, just PnP?
Good points on redundancy, a few small vs one large. I'm giving that some investigation to compare cost, power budgets etc.
Good call on the SDN compatibilty as I hadn't thought of the outdating possibility. It turns out that my Omada controller and both APs are "SDN Integrated" and fully compatible though they are two years old.
Worthwhile to note that since I originally set up the APs I haven't really used the SDN or cloud feature as it's just poofery for AP use. It lets me monitor how many devices are using how much bandwidth and I can block one if i wanted.
That's NOT useful in my application, it's just a bell$whistle thing. However, in the case of the switch, it MIGHT be useful for setting up Vlans or other management, I don't know. It's sales pitch is Cloud based monitoring and management, which seems not much value in a static network (after set up and tweaking)... mostly bell&whistle value. But I already have it, so it's a slight factor in product selection.
I really like the future-proofing of the Gb ports and the high power budget, but as stated, the one-basket scenario has a downside as my V7 illustrated.
BTW: The Zyxels are either NA or outrageous.
Good points; For the record, I should add that the V7 switch, the 8-port switch in the shop as well as the computer room (CamPC/modem/router) each have dedicated UPSes/ surge protectors. This gives a little bit of run time during an outage and most importantly isolates everything from most supply voltage issues.i just read through this entire post. I was thinking an unstable or glitchy power situation. And reading further that seems to have been discovered. I was thinking maybe Surly's electricity to his house was even to blame/glitchy.
My Mom had a house in Naperville that seems to have had more faulty electronics than Anything i'd ever seen. ( The Fermi Lab Particle accelerator was just down the Highway LOL) maybe there were unhappy electrons....Anyhow....
I used to go crazy chasing network issues, and it was partially failed/or failed switch router combo's or Modem switch combos almost all the time.
So I'm glad you found the problem...
I started out buying an enterprise switch, and realize for home use fanless is nice of you arent running too many cams. Like somebody above said, maybe a couple fanless POE switches. unmanaged is fine for home surveillance, unless you wanna get fancy pants with Vlans.
Of course fanless (I assume) is not a typical feature of high-wattage switches.
That's an impressive little switch, right there. Added to my list for future expansion in the shop which has a 4poe/4non switch right now.What do you consider high wattage? I have an incredibly modest fanless VLAN capable switch for IPC's which I picked up back when I started this journey, and it's only a 4 port but has a 120W budget. You can cycle a port's power without losing PoE to that device downstream, test for shorts, and loops etc. At the time all I cared about was decent wattages, an intuitive web UI, and that it was basic, and advanced VLAN capable including 802.1Q (basic/advanced) so it could continue to serve as my network grew. I guess, in your case, it would also matter where the switch is physically (in which building), and whether something like this would play in your ecosystem.
