14.2 Focus and Zoom Adjustment
To facilitate the focus and zoom adjustments, a network connection will need
to be established with the camera to view the live video on a web browser.
Refer to Sections 3 and 7 for details on accessing the camera with a web
browser.
If the LED is not flashing while the camera is wired up and the power is turned
on, you may need to press the setup button to wake the camera from any of its
low powered modes. In some configurations, pressing the setup button may
also be required to enable the Ethernet port.
Establish a connection to the camera by typing the address of the camera into
the web browser (Factory default IP address is 192.168.1.90). The home page
of the camera should come up once the address is entered.
To view the video select an appropriate Video Display Size. If you have a
direct connection, you will get the best results by displaying the larger
1280x720 video. The smaller video display sizes are useful when working
with bandwidth limited connections.
•
Loosen the two thumbscrews on the adjustment rings of the lens. It is
generally preferred to adjust the zoom (i.e. frame the scene), and then the
focus. Once the zoom is adjusted as desired, tighten the thumbscrew so
that the zoom will not inadvertently move when the focus is adjusted.
•
Adjust the focus ring and then tighten its thumbscrew as well.
If the camera is targeted on an object that is far away (100 m or
more), then it may be beneficial to adjust the lens before taking
the camera into the field by using an object that is at a similar
distance away.
14.2.1 Using the Focusing Number
The main purpose of the focusing number is to facilitate focusing the camera
when using a display in outdoor sunlight. The sunlight can make it difficult to
distinguish fine detail on a computer screen
The focusing number is displayed on the home page of the web interface to
assist with focusing the CC5MPX camera. The focusing number is a number
that generally increases as an image becomes more “in-focus”.
The lens should be adjusted so that the focusing number reads near its
maximum achievable value. The numbers are relative only and are dependent
on the actual scene, so a value of 9000 may be in focus for one scene and a
value of 2700 may be the maximum for another scene. The numbers are most
useful when the lens is near its best focus position.
The camera should be in a fixed position when using the focusing numbers. If
the camera is allowed to move then movement will account for increasing or
decreasing numbers.
