2. Mount the optional camera mounting bracket to a ceiling or wall.
Using an electrical box, fix the camera mounting bracket with its
supplied screws. Run the coaxial cable through the hole in the
bracket.
3. Set the camera mounting bracket securely in the threaded hole in
the camera mount rotating the bracket’s pedestal.
Notes
• The camera mount can be mounted to both the top and bottom of
the camera. Attach the bracket to either side depending on
installation conditions.
• Use the camera mount fixing screw to attach or detach the
camera mount.
4. Set the camera orientation, and secure the camera.
After setting the camera orientation, rotate the lock lever to secure
the camera.
Notes
• To avoid damaging the internal sections of
the camera's lens mount, be sure that the
lens flange is less than 5 mm thick as
illustrated on the right.
• C-mount lenses must be used in
conjunction with the Lens Mounting Adapter
CF-5 (optional).
6. ADJUSTMENT
1. Switch on the power supply of 12 V DC after completing camera
connections.
The power is supplied to the camera.
2. Connect the monitor to the Video Output terminal to permit a picture
to be viewed on the monitor.
3. Set the Shutter Speed switch to ON if light flicker is annoying.
Light licker may interfere with the view under fluorescent lamps in
the area where power frequency is 50 Hz. In such cases, set the
Shutter Speed switch to "ON" position, and the image free from
flickering can be obtained.
Note
If the Shutter Speed switch is set to the ON position, sensitivity is
reduced compared to operation in the OFF position. When using
the camera in a dark location, or where light flicker is not an
annoyance, set the switch to the OFF position.
4. Adjust the camera angle.
Loosen the camera mounting bracket’s lock lever to point the
camera to the desired direction, then retighten the lock lever to fix
the camera securely.
5. Adjust the angle of view with the Zoom ring and adjust the focus
with the Focus ring for the best possible picture reproduction.
7. CONNECTIONS
Notes
• Since the Iris control (for sensitivity adjustment) is factory-preset to
an optimum position for general use, avoid tampering with it in
normal conditions. Turning the control unnecessarily could cause
reduced picture quality or equipment failure. When the Iris control
needs to be readjusted to match a specific subject, first set both the
Adjustment switch and the Backlight Compensation switch to the
OFF position, then adjust the control to an optimum level. After
adjustment, place a hand over the lens for several seconds and then
release to check the lens for correct iris operation.
• If the focus is adjusted for a subject under good lighting conditions,
the subject may go out of focus when conditions become dark. To
avoid this, adjust the lens focus after setting the Adjustment switch to
the ON position. Be sure to switch it back to the OFF position after
completing lens adjustment.
• When a subject appears out of focus because it is closer than the
lens’ minimum close-up distance, adjust the focus as follows:
(Back focal length adjustment)
(1) Attach the lens.
(2) Loosen the Back focal length adjustment ring fixing screw.
(3) Rotate the Back focal length adjustment ring to set it to an
optimum position.
(4) Retighten the Back focal length adjustment ring fixing screw.
