That camera should have a 12v inlet port for the solar panel to hook to. Take a $15 lawn mower battery from Wal-Mart, hook it to the inlet port. You must hook a resistor in series to limit the current, otherwise you will burn it up.

I took an old wall plug transformer that had the correct output connector. Cut off the connector. Soldered on a 100 ohm resistor. Soldered on 6ft extra wire, with lugs.
