About network problem.

The network goes on disconnecting in raspberry pi. Is it because of power issue? I gave 5volt power from 12 volt battery, and I have connected wifi dongle and camera in USB ports..

You'll need to give much more detail if you expect anybody to provide a helpful answer...

+1, particularly about "5volt power from 12 volt battery". (But not only that!)

+1 to more details (wifi chipset, logfiles, etc)

If it's your wifi dongle which is dropping the connection, some wifi adapters have a power saving feature that makes them shut down and the OS doesn't bring them up again (by default). Search for "iwconfig wlan0 power off" and you might find some things to try.
