    I want to power a small security cam on my porch. What is the best/cheapest way to get USB power to it?

    DIY solution would be good. Would I be able to solder up a usb/network-cable solution?

    Presumably you're getting the imaging back via Ethernet? If so then probably the cheapest way would probably be a pair of Power-over-Ethernet injectors, thence a suitable step-down power supply at the camera end (coupla dollars off eBay for something like one of these), or whatever's needed to give you reliable/stable +5 volts at the camera end.

    Best/easiest way would be a PoE camera, but probably not the cheapest option...

    If your camera is wireless for the imaging then mebbe a small solar panel 'n regulator, suitable battery and again one of those power supplies as above.

    No need for anything that complex, its just for power, so get a couple of extension cables and join them together, or get some plugs/sockets and use whatever cabling in between

    Image is just coming back via wifi, so the cable I need is purely for power.

    At the moment I'm just leaning towards a 5m power extension cable and 2m usb cable. Was just hoping to hack something together with network cable so that I didn't have to waste an extension lead.

    get a USB cable, cut it in half, extend with any cable. Volt drop over a short distance like that won't be much as long as you don't use stupidly thin cable
