Readit NewsEMHASS is an interesting tool to perform the optimisation.
go2rtc also works nicely for on demand transcoding of my H265-only cams to H264 to view the live stream in Firefox.
More flexible in some ways, I’m using 1 port of my 8-way injector to add PoE to the WAN interface of my router. In conjunction with an active PoE “splitter” on the far end I can remotely power the GPON modem on the other side of the house and power everything from one UPS.
I also made sure to get a Mode A “gigabit” injector in order to power 2x PoE cameras in a location with a single Cat6 drop. On the far end there’s just a passive splitter, each camera only gets 2 pairs which run both 100Mbit Ethernet and PoE. Cheaper “non-gigabit” PoE Mode B injectors save a buck by omitting the isolation transformers and instead inject DC onto the spare pairs, so not compatible with pair scavenging.
MikroTik’s PoE switches also use Mode B. They’re gigabit so have to include the isolation transformers anyway, presumably this is due to their ability to operate in 24V passive PoE mode. I was going to get a MikroTik switch but my pair scavenging requirements drove me down the path of a separate multi-port injector, which worked out to be a lot cheaper too!
8 port injector with a decently powerful 56V power supply was approx $100 via AliExpress.
Only drawback is a bit more cabling and no ability to remote power cycle an individual port.
So about 3 months ago the RJ45 cable in my cable modem melted. I thought it was a freak accident. I checked all of my networking equipment, checked my outlets, etc. No problems. So I installed a new cable and then everything was fine.
Cue 2 weeks ago. Connectivity became intermittent and then finally I had no internet for almost a week. Comcast wouldn't be able to send anyone out for a month. So I started digging around for the problem. A little over a year ago they sent out techs to work on my neighbors internet and in the process foolishly cut my coax. So I started from the cable tap and worked my way backwards.
There wasn't a continuity problem from what I could tell, no one either intentionally or unintentionally cut the cable. Then I look on the back of my house where the coax from the street is bonded to my home's grounding rod. Everything to the right of the bond was completely melted and still super hot. NOT GOOD.
So I did some testing of the bonding wire to the ground, the resistance was 37 ohms (should be much less than this). And there were no other electrical problems. My thought at the time was somehow power was being backfed from the cable tap to my home. So I removed the cable from the street and disconnected everything inside that was touch this cable.
Almost immediately I start getting voltage drops in my house, can't even run the microwave. That's when I realized what was really going on. The cable line was being used as a return path because the neutral for my neighborhood was at least partially severed.
It was so bad that if I increased voltage load in my home past a certain point then the streetlights in the front of my home would completely turn off.. Yes I could turn city infrastructure off and on by toggling the voltage load in my home.
The power company within a few hours had a crew come out to diagnose and fix the issue since it's actually potentially dangerous. They confirmed for me it was indeed a bad neutral. As soon as they replaced it I spliced my coax line, reconnected it, and everything worked perfectly.
Here in Australia the coax connection from the street typically goes through a galvanic isolator to avoid this situation, rather than being bonded to the earth.
