How to power dahua IPC HFW 5431 EP-Z ?

Yep, it's PoE. But if you've got no PoE and it's going to be two weeks before a PoE injector arrives in the mail what can I do?
Why do I ask?
Because it has a tail marked 'power'.
I assume that's power in?
Hope so. I stuck 12v on it and it didn't work. Hope it didn't break it.
Why would a camera have power out?
I'm all confused. Any help?

What do you mean it didn't work?

Did you hear the IR filter click and if you turn off the lights does the red infrared lights kick on? If so then it is working, but seeing it on your computer is another story.

What amps was your 12v power supply? It needs to be enough to power it.

by didn't work I meant it doesn't show on smartPSS-lite. which it did until i did what I've just done.
the power supply is marked 12v 1.5A pos centre
the cam says 12v 1A/poe
are you saying you can confirm that's power it and it should work?

I have the thing outside. it used to be inside. to save running ethernet which I don't have any of I used EoP . I took the nvr and the camera out there together. the cam plugged into the nvr PoE.
The nvr plugged into EoP to get messages to the router.
Worked fine.

Then I thought why the hell am I doing this? I can bring the nvr back inside and run the ethernet between nvr and camera through EoP just like I'm doing for the nvr.
Where I miscalculated is the camera wants PoE.
Which EoP doesn't deliver.

So now I have it all mounted out there and powerless.

That's too many amps, but it should be fine as the camera should only draw as many amps as it needs.

So you now have EoP running from the camera to where? The NVR POE ports?

Use 12v 2a , this camera need poe+

 

[abrogard]

the setup is now: camera > ethernet line (a PoE line) > EoP adapter > house wiring > Eop adapter > ethernet line > nvr which can't work because it leaves the camera unpowered.

what was working well before was: house wiring > EoP adapter > ethernet > nvr > ethernet PoE > camera.

what i am trying to do now is camera > EoP > router
in parallel with power supply > camera.

does that confuse everything... ?

what's the point of using 2A if it 'needs' PoE ?

are you saying it CAN use the power line if we give enough power?

I just gave it plenty of power. 12V with 5A available. It's not interested.

I very vaguely remember reading something interesting all those years ago about that 12v line. Perhaps I read it is non functional or needs configuration or something. Anyone can point to the manual for these? I better go look for one..

Ho ho ho.... relax everyone... it IS working !

I just clicked where it should be in the smart pss screen a few times and got messages flashing up and going away saying 'this video is being requested' and then suddenly gawdamn if it didn't start streaming...

so it's a goer. beautiful. I don't need the PoE injector after all. Though I might use it when it gets here. Right now it is working with camera data going EoP and camera power coming from seperate Power Supply.

Thanks for looking and trying, everyone. I much appreciate it.

A reason for a camera to have a power out connection would be to power an external microphone, and there are some cameras that have this. The spec sheet for the 5431EP-Z doesn't mention a power out, so I'd assume it does not have that feature. The spec sheet also says the power draw is 11.5 watts. It should work with the 12 volt input if it works with POE. Typically the cameras down convert the POE power to 12 volts, then parallel that with the 12 volt power input. The 12 volt line has a series diode to protect against reversed polarity and pushing POE power out the power input jack. If the camera really doesn't work with the 12 volt input, the logical failure points are either the diode (very unlikely), or damaged wiring for the 12 volt input. If you haven't turned off the IR lights, just power it up in a dark room and see if the IR lights come on.
