Is there a risk of losing frames or images while switching cameras?
All of CyberOptics’ analog PCI frame grabbers have a four to one multiplexer before the video input. That means you can connect up to four cameras and select any single camera to be the input at any time. When you switch from one camera to another, you will always lose data unless your cameras are genlocked. Switching always occurs at the end of a field of video. If the cameras are not genlocked, then the fields of video from the four cameras will end at different times. When you switch from one camera to the next, you switch from the end of a field into the middle of another field. You will always lose the rest of that field plus the next complete field.The frame grabber resynchronizes during the full field. The average loss is 1 to 1 fields on each camera switch. The Imagenation PXC200AL is an exception and will lose up to two complete frames. If you like the features and price of the PXC200A and you require camera switching, then you need the Imagenation PXC200AF with the option pac
