Matters not, because the next iteration you’ll do just that! The same with how you learned and iterated your network to a proven wiring topology in using a dedicated multi channel PSU.Point taken. For the small difference in price, buying a US made power supply might be a better option. Had I known when purchasing, I would have likely done that.
Initially internal IR was disabled. After an hour or so I turned on Smart IR to see how that changed the available light once it got dark. An hour later is when the camera dropped off line.Do you have the camera's internal IR shut off? I'm running about 10 Dahua cams with 4 watt illuminators on 802.3.af ports with no issues. I'll qualify the "no issues" with one thing. A few of the cameras cycle their internal IR on bootup. If a camera resets in the dark when the external IR is active, the port can overload during the boot sequence, causing a reboot, causing an overload,..... Happens to me maybe once a year on one camera.
Wow, you've got a bunch of potential issues there with the cable length and number of connectors. You will lose some power just from the cable length. If I crunched the numbers right it's about a half watt, no bigge by itself. Looks like about 8 connectors in the run, each of those will have some power loss, plus the extender will draw some power (spec sheet says 2 watts max). My own experience with electrical gadgets is that the majority of failures occur at connections, so I try to minimize them. Some people go for neatness with a patch panel between the POE switch and cable run to the camera. I go for reliability and plug the run to the camera straight into the switch. In your situation I'd start by just undoing and redoing each connector a few times. After that, maybe bypassing individual cable runs and connectors to isolate what is hopefully a single problem. I have a couple hundred foot spare cat6 with RJ45s for temporary runs and troubleshooting, and with gadgets like the POE splitters I always keeps a spare for troubleshooting.Unifi PoE switch Cat6 -> Keystone at house dmarc -> Cat6 to GPeR Poe Extender at dmarc -> Cat 6 to mailbox Active Splitter -> Active Spliter data cable to camera -> Active Splitter barrel power cable to Y Splitter -> One Y to camera for power -> Other Y to IR.
I've bypassed the diode on about 5 different dahua models. With each new generation of camera the geometries are smaller and the job gets more difficult and risky. On the 5442 zoom the diode isn't much bigger than my iron tip. With all of them, a 4 watt load is the max they can reasonably support. It's nice getting rid of all the extra cables and splitters out at the camera.I'd guess that most Dahua or Dahua OEMed cameras would work as well.
I actually spent several minutes going through all of the settings and I didn't find any difference. Would be a GREAT tool if someone could find a way to export the settings to a file for easy review!Good thing you have another camera. Troubleshooting gets pretty difficult when you aren't able to swap out every component if you have to. Now it's down to figuring out what's different about the cameras. You could compare every setting between the two.
