# Connect analog cameras to the computer

Connect one to four cameras

Connect each camera to one of the inputs of the Picolo Alert encoder board.

Furthermore:

▪Take note of which camera is connected to which input of the board.

▪Make sure that all four switches on the board are in the position opposite to their labels.

▪Create or open an experiment, choose Setup > Experiment Settings, then select Live tracking and under Video Source select the camera inputs. Next, view the mixed camera image. See Video source

Maximum number of analog cameras

EthoVision XT supports up to 4 analog cameras connected to one Picolo Alert encoder board.

note The Quad Unit Processor, which was previously used to connect up to 16 analog cameras, is no longer available. The 16-camera analog configuration is therefore no longer supported.

Notes

▪The Picolo U4/U8 H.264 boards are no longer supported with EthoVision XT.
