Pelco Manual C1917M (12/97) 3
2.0 DESCRIPTION
The CC4700-2 color video camera has the following features:
Imager
The camera uses a 1/2-inch CCD (Charge Coupled Device).
High Sensitivity
The camera gives a clear picture even under very gloomy conditions.
CCD Iris Function
Even when a manual iris lens is fitted, the sensitivity is automatically adjusted ac-
cording to the incident light level. This keeps the video signal at a suitable level.
Electronic Shutter Function
Eight shutter speeds are available for various shooting conditions.
Lockable to AC power Frequency
The vertical drive frequency of the camera can be locked to the AC power fre-
quency (60 Hz) instead of the internal clock of the camera (59.94 Hz), avoiding
picture roll during camera switching operations.
Auto-Iris Lenses
A C-mount auto-iris lens can be used by connecting the lens cable to the camera
with the plug that is supplied.
High Resolution
The number of CCD picture elements (about 380,000) is sufficient to ensure high
resolution.
Automatic Adjustment of White Balance
The automatic adjustment mode adjusts the white balance according to a value
stored in memory; alternatively, the automatic tracing mode continuously responds
to the lighting conditions to adjust the white balance. Thus a picture with an appro-
priate color balance is always obtained.
