2.2 Accessing the camera from the Internet
Once installed, the camera is accessible on the local network (LAN). Configure the
router/firewall to allow incoming data traffic to access the camera from the Internet.
For security reasons this is usually done on a specific port. Please refer to the
documentation for router/firewall for further instructions.
2.3 Adjusting the image and focus
To adjust the position of the lens:
1. Open the Live View page in your web browser.
2. Check the image in the Live View page, and move the lens to the desired position.
To focus the GANZ ZN-XXX, follow the instructions below.
- From
Setup
page that you access via the Setup link, open the
Installation
page.
- Unscrew the zoom puller on the lens by turning it anti-clockwise. Adjust the zoom
setting as required. Re-tighten the zoom puller.
- From
Setup
page that you access via the Setup link, open the
Installation
page.
- Unscrew the zoom puller on the lens by turning it anti-clockwise. Adjust the zoom
setting as required. Re-tighten the zoom puller.
Note:
The DC-Iris should always be disabled while focusing the camera. This opens the iris to its
maximum, which gives the smallest depth of field, thus the best conditions for correct focusing. When
the focus is set with this method, it will then be maintained in any light conditions.
2.4 Back focus adjustment
When the lens is changed to a non-standard lens or when the focus achieved using
the instructions above is not satisfactory, perform back focus adjustment as follows:
1. Loosen the screw that holds the C/CS-ring. CS is standard on EVC ZN-XXX. In case your
lens is C mount type, please mount C-mount adaptor ring already given in the box.
2. Direct the camera towards an object at least 3 meters away, set the zoom puller to max
wide and check that it is possible to focus the lens.
3. Set the zoom puller to max tele and again check whether it is possible to focus the lens.
4. Direct the camera towards a close object, about 30cm away, set the zoom puller to max
wide and check whether it is possible to focus the lens.
5. Set the zoom puller to max tele and again check whether it is possible to focus the lens.
6. In case it is not possible to focus the lens in any of the four situations above, adjust the C/
CS-ring, and go back to step 2.
7. Tighten the screw that holds the C/CS-ring again.
8.
After making the back focus adjustment as explained above, adjust the zoom and
focus position for the desired view.
