12V POE?

Ive got a couple of cameras that as far as I can see are 12V. Reolink RLC-410. They run off an injection switch but that is 53V so I cant power it during power off.

I connected the cameras poe cable via a standalone poe injector that I connect to my Gizzu 12V port (light on injector is on) and lan to a switch that also runs off the ups.

However no comms lights on the switch for the cameras (it works for other devices eg poe router running off the 48V poe port) and no feed on the camera app.

Can I actually use poe for 12v or do I need to run an electrical cable from the ups to the camera in addition to a lan cable?

Thanks!
 
Why not just get a NVR with POE

I have the Dahua one 16ch with 8xPOE works well but same software as most being chinese

PoE is 48V, how you going to get 48 volts from a 12v socket, plug the injector into the (220v) UPS.
 
Not all POE is 48v all my outdoor routers are 24v ubiquity for instance. Cameras are rated at 12v as per the manual.

How long is the lan cable and is it proper copper or copper clad?

How many amps can the 12v poe injector do?
 
@soulsmile You need to consider that there are different POE standards such as passive POE, 802.3af, IEEE 802.3at and IEEE 802.3bt

For example your UBNT stuff is Passive POE at 24V -there is no intelligence there, it's 24v on the wire-easy to diy

Your cams say DC12V & PoE (IEEE 802.3af), so it's not "12VDC POE", it's one or the other. Either you give it standard 12V on its barrel jack or use an 802.3af compliant injector which is 48v 'ish

If your goal is long runtime and u in an ideal world you can look at a edgeswitch 8 powered by DC from batteries - will give you both 802.3af and Passive POE 24V POE out on the ports and long runtime

Thank you! Amazing and useful complete information. Much obliged.

I've just looked at the spec for those cameras. It looks like they run on 48v POE or 12v DC (via a barrel connector).

Since the camera only uses 10/100mbps ethernet you could use one of these to get power and data to the camera then you plus the DC connector into the gizzu power bank.

Thank you hope this may work for me. Issue is Im using one of those lan combiners splitters aka 2 poe lines combined onto 1lan and split again to two cameras so not sure it will work. Pipes already under ground. Didn't design this layout so was done without thought to loadshedding. Thanks again!
