Digital processing enables wide array of functions
Desired hue and tint can be adjusted with 6-vector independently variable masking. Even at wide dynamic range, auto-knee and
dynamic chroma can provide superbly colored images.
The versatile detail compensating functions allow optimum contour compensation to match the scene.
•
Intelligent automatic level control (ALC)
Digital light metering of either the overall image or an iris gate with variable size and position, computer chip driven automatic gain
control (AGC), lens iris and auto electronic shutter (AES) provide comprehensive control with respect to a wide variation in light. The
ALC level setting is also variable.
•
Three application files
Different setting data according to the application and scene can be stored in 3 application files.
•
Bi-directional data communication
The camera can be connected to a personal computer via RS-232C for two-way data communications to provide finely detailed camera
control. An identification (ID) code can be assigned to each camera in a system and allow remotely controlling multiple cameras from
a single computer.
Notes to users
Important safety notes
l Use this camera with a 12 VDC power supply.
l Observe that flammable objects, water or metal do not enter the camera interior. These may lead to failure or accident.
l Do not modify the camera or use the camera with external covers removed. These may cause failure, void any warranties and pose a
safety hazard.
l Stop using the camera at the approach of an electrical storm (thunder audible). Protect the camera from rain if using it outdoors.
l In event the camera shows any abnormality, switch off the camera and disconnect the power cord. Contact a Hitachi Denshi service

Operating considerations
l Power supply
Check that the supplied voltage is between 10.5 and 17 VDC. Inadequate voltage can affect color fidelity and cause noise,
while voltage over 17 V can damage the camera.
l Connectors
Confirm the power is off before connecting or disconnecting a signal cable. Grasp connectors by the body, not the attached
wires.
