Just wondering if anyone else has seen this before...
DS-2CD2086G2-IU, B-R-G3-0, V5.5.801 build 211105
PoE-powered camera one day stopped working. Mounted under a porch out of the rain, exposed to temperatures around -5C to 35C. Solid core Cat 5 run of around 10 feet. No sign of any cable damage, and the cable tests fine.
Brought the camera inside and connected it directly with a 1m sold core lead to my PoE switch - but it doesn't power on. I've read one or two examples online of these cameras PoE module failing suddenly, so I tried powering it via the 12V DC power jack instead using a Netgear 12V 1A adapter (camera says it only needs 0.5A @ 12V). Camera will boot up instantly when the 12V DC is connected, suggesting the PoE module may indeed have died.
However, it will not negotiate above 10Mbps to my Netgear switch. I've tried forcing 100mbps and you can see the switch make 3-4 attempts to negotiate, before giving up and falling back to 10Mbps. Hmm.
I can get a third party PoE to 12V DC splitter cheaply enough and put the camera back up, if it's just the PoE module failing and this is a reasonably well known issue. However, the 10Mbps speed is more of an issue for two reasons: a) These are 4k cameras and I'm using both the main stream and substream, and the main stream is set to 16Mbps, so 10Mbps causes dropouts and b) if the camera is on its way out and likely to die, I'd rather replace it now - last thing I want is it failing at 3am, or while I'm away.
Camera was second hand so no warranties.
Grateful for any thoughts or similar experiences...
