described in EIA ANSI/EIA-330, and an automatic white clipper and automatic
gain control circuits.
2.6.3
High Resolution Color Camera
All electronic components and circuits shall be solid state.
Signal-to-noise ratio shall not be less than 50 dB unweighted. The camera
shall exhibit no geometric distortion. The lens mount shall be a C-mount,
and the camera shall have a back focus adjustment. The camera shall
operate from 10 to 55 degrees C 14 to 131 degrees F without auxiliary
heating or cooling, and with no change in picture quality or resolution.
The camera shall operate on 60 Hz AC power, and shall be capable of
operating at a voltage of [105 to 130] [205 to 240] [24] Volts.

of 0.2 lux (0.2 footcandle) 0.2 footcandle minimum.
2.6.3.3
Camera Synchronization
The camera shall have an input for external sync, and shall automatically
switch over to internal sync if external sync is not present. The camera
shall also have the capability of synchronization by line-locking to the AC
power line frequency at the zero crossing point, and shall provide not less
than plus or minus 90 degrees of vertical phase adjustment.
2.6.3.4
Connectors
Cameras with lenses having auto iris, manual iris, or zoom and focus
functions shall be supplied with connectors and wiring as needed to operate
