Solar powering CCTV

[EstKet]

Hello,

I need a CCTV system that is completely wireless and would like to solar power it all. I have my eyes on a suitable camera with internal storage, so I will not need a separate recording device. However, the camera is powered by an ethernet cable. Is there any way I can solar power this? If so, what kind of solar panel would I need?

Power for the camera:
Power over Ethernet IEEE 802.3af/802.3at Type 1 Class 3
max 3.7 W

Alternatively, I could use a camera with a DVR, but this would mean solar powering this too. I have been told it might not be possible to solar power a DVR because they use a lot of power. Can anybody offer any advice on this?

Any help will be greatly appreciated.

find out what voltage your camera uses, get a gadget like that:
Power Over Ethernet Adapter / Injector / Extractor, Passive POE Kit Cat5 Cable | eBay
feed it with that voltage.
for solar use a solar panel, battery and a charge controller. it will be running 12v. if camera voltage
is lower than 12v get some little dc-dc converter.

stand-alone dvr do take quite a bit of energy...
