This application should take videosignal from webcams (from 1 to 10 webcams) and record it to the SD card. The reprodaction of video is no needed, only storing to SD card. One more setting is choosing video format and size of video before saving. So, waiting for ur extra questions and responses.
Reward is 200$ (max).
I forget about one important thing - it should start to work from turning on the phone and at the background mode.
