2.6.1.3
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 60 Hz line frequency at the zero crossing point, and shall provide
not less than plus or minus 90 degrees of vertical phase adjustment.
2.6.1.4
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
the lens functions. Video signal output connector shall be a BNC. Cameras
with integral fiber optic video transmitters shall have straight-tip
bayonet type fiber optic video output connectors. A connector shall be
provided for external sync input.
2.6.1.5
Automatic Circuits
The camera shall have circuitry to establish a reference black level as
described in EIA ANSI/EIA-330, and an automatic white clipper and automatic
gain control circuits.
2.6.2
Low Light Monochrome Camera
The video camera shall conform to EIA 170 and EIA ANSI/EIA-330
specifications. All electronic components and circuits shall be solid
state. Signal-to-noise ratio shall not be less than 42 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 minus 10.0 degrees C to plus 55 degrees C (14 to 131
degrees F) 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 or operating at a voltage of [105
to 130] [205 to 240] [24] Volts.
2.6.2.1
Solid State Imager
The camera shall have a solid state imager, and the picture produced by the
camera shall be free of blemishes as defined by EIA ANSI/EIA-330. The
camera shall provide not less than 550 lines of horizontal resolution, and
resolution shall not vary over the life of the camera.
2.6.2.2

Camera shall provide full video output with the infrared cut-off filter
installed, and a scene reflectivity of 90 percent using an f/1.2 lens
giving a camera faceplate illumination of 0.02 lx (0.002 footcandle) 0.002
footcandleminimum.
2.6.2.3
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 60 Hz line frequency at the zero crossing point, and shall provide
not less than plus or minus 90 degrees of vertical phase adjustment.
