How to use the Camera Master
Camera
-
Sync = 40 IRE +/- 5
Luminance = 100 IRE +/- 10
Colorburst = 40 IRE +/- 5
Composite = 140 IRE
Sync too low - The picture will break up or roll.
Sync too high - any black portion of the picture will be more grey and the
dynamic range of the picture will be degraded. Peak white level will also be
compressed causing a blooming effect (loss of picture definition).
Luminance(Iris) too low - the picture will be dim with less than desired dynamic
range and the white picture elements will not be pure white.
Luminance(Iris) too high - the picture can be washed out causing loss of
picture definition *Note all cameras on the system need to be the same, some
cameras can be set higher but if they are not all the same the white portions
of the picture will not be the same brightness when a monitor is switched
between them.
Color burst too low - the color monitor will turn its color receiver off
causing a Black and White only picture. You can see this effect on long cable
runs. The solution is to install a video equalizer GB-60 in the line and adjust
the color burst back to 40 I.R.E. units.
Color burst too high - the picture will display color flaring and reduction
of detail at the edge of the color flare.
SYNC, WHITE, and COLOR BURST are the three basic measurements to
make to insure proper operation of your CCTV system.
