Specifications
9.2.7 H Phase
This function is active when the camera operates with external synchronisation (H+V).
Use the H-phase setting to adjust Horizontal timing differences when cameras are H-V
synchronised. Input standard CVBS synchronisation signals.
9.2.8 ext V Phase
This function is active when the camera operates with external synchronisation.
(External V)
Use the extV phase setting to adjust V phase differences when cameras are used in a
system. Input; Positive V-pulse, 8-50% duty cycle, 5 V CMOS level.
