IP camera PoE length

[hometownfl]

I'm looking to install some IP security cameras throughout our property. I'm going to power these via PoE. Problem is some cameras will probably end up being further than 300ft from our DVR, which I read is where PoE drops off at. Is there any way for me to run the PoE further? Anyone have some experience with this?

The only solution would be a PoE extender, but they can be pricey. You could always find a PoE switch, but I'm not sure on compatability with your DVR.

As dougp mentions, an extender. Or just use a PoE injector for the cameras that are beyond 325 feet.

Do they all need ran to the DVR box?

Only problem with injectors is they require a power source. Extenders don't, but I'm also not aware of how they accomplish this or if they somehow affect bandwidth.

I want to use a PoE switch to make it look cleaner. The Camera's I'm using are 12v, so I need some kind of adapter right? Or maybe just a 12v switch? I can't put a switch or injector part of the way through because there are no outlets where the cables will be run. I probably should have mentioned that in my original post. Thanks for the quick responses everyone!

Are you aware if the camera's are PoE?

Yes they are.

Yes they are.

As long as the PoE switch supports the version of PoE your cameras have, it should be fine. I'm not really an expert though, just use PoE in the office for our desk phones.

I'm confused, PoE runs at a straight 48V DC (or 56V for 60 watt high end equipment, the switch/injector has to support this standard). 12v pushes alot of amperage, amperage that the 24awg wires in ethernet cable can't handle. I think we need better info on the equipment. I would say just run an ethernet line to equipment and use a PoE injector, either way you can only push power so far physically so if you're really going for that kind of range you're going to need power at site.

Researching that info it seems pretty clear that the cameras are not PoE. Instead they have an extra module you can buy that takes a PoE line and then converts it to the 12v + network that the camera needs to function. There is no native PoE support on that camera.

Is there a device that I can use the PoE switch, but split out the power to the barrel connector? Without losing the data? (This is why I need help lol)

 

[heymrdj]

I took another look at it and Geovision does not support any form of PoE on that camera. The adapter I saw was for another line of cameras, these cameras had barrel jacks, but ran at 48vdc instead of 12. (PoE runs at 48V). Geovision basically says you need a higher end model of their cameras to support PoE. If they ran at 48v there could be some resolution.

Now not all is gone. There are adapters (3rd party) for this situation. However there's no guarantee of a compatible barrel. Choice there is yours if you can find a match: http://www.directron.com/pos1002.html?gsear=1

PoE to 12v converter.
