Arduino FPV Robot

Hello to evetyone.I have make an Arduino FPV Robot and i have a problem.My problem is that i use the ip webcam(for live straming) app and when the robot go away the video freeze.Can you suggest me similar better apps,please?I know that is not an Arduino problem but i don't know what to do.Thank you for your time.

The problem most probably is the limited range of the wireless components. A more powerful sender in the robot may help. If not, choose a different technology, e.g. WLAN instead of Bluetooth.
