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 homepage
of the camera should appear once the address is entered.
To view the video, select an appropriate Video Display Size. With a direct
connection, the best results are obtained by displaying the larger 1280 x 720
video. The smaller video display sizes are useful when working with the
bandwidth limited connections.
• Loosen the two thumb screws 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 tighten its thumbscrew as well.
If the camera is targeted on an object that is far away (100 m or
more), 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.
8.11.2.1 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 homepage of the web interface to
assist with focusing the CC5MPX camera (see FIGURE 8-51 ). The focusing
number is a number that generally increases as an images becomes more “in-
focus.”
The lens should be adjusted so that the focusing number reads near its
maximum achievable value. The numbers are relative 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.
There may be instances where the focusing numbers cannot be used to focus
the CC5MPX. One such scene may be where a nearby object is desired to be in
focus, and the background may be out of focus. However, for most “scene”
images where near and far objects are not involved, the focusing numbers work
well.
