Camera Check
The multiplexer multicamera display capability makes check-
ing camera performance as simple as comparing two pictures
on one screen. This method is preferable to the direct camera
to monitor technique because it allows precise adjustment of
each camera against a chosen reference camera. This mini-
mizes differences between cameras, and optimizes picture
quality.
NOTE: Before performing a camera check, complete the
monitor calibration procedure described in the
previous section. Adjusting camera picture quality
is more effective on a monitor which is already
calibrated.
The camera check procedure is as follows:
1. Complete the monitor calibration procedure.
2. Connect all system cameras directly to the multiplexer
camera inputs. Remove all connections to the looping
(lower) camera outputs.
3. Make sure that the multiplexer is set up for 75 ohm
termination (the default state). The switches on the back
panel should be down.
4. Select the format (2x2, 3x3 or 4x4) which displays all of
the attached cameras.
5. Pick the best looking picture and use that camera as a
reference. If necessary, adjust the camera for an optimum
picture. Do NOT adjust the monitor.
6. Adjust each remaining camera, in turn, for an optimum
picture. Try to obtain the same picture quality as the
reference camera.
The cameras are now correctly adjusted with respect to the
calibrated monitor and each other. You may now adjust the
monitor for the best overall display. If you choose to make
further monitor adjustments, it is best to do so with all cameras
displayed.
