*** Vsw jumper one or the other must be bridged,
otherwise Vsw pad is not getting power.
Vsw is not only for powering Camera-2,
You can power VTX or other devices via Vsw also.
*** Two cameras should use identical video format,
both PAL or both NTSC
*** Double check out Camera signal and power cables
before powering them up.
