23. Maintenance
The CCFC requires little maintenance. Keeping the camera lens window clean is important for the
longevity of the camera and photo and video quality.
23.1 Lithium battery
The camera is equipped with a lithium thionyl chloride battery. The battery maintains the clock
functionality for periods when power is not connected to the camera. The expected battery life is
10 years. It is recommended that the battery be replaced by a certified repair facility.
23.2 Window and lens cleaning
If the enclosure window or lens requires cleaning, it is very important that only a proper lens cloth
or lens tissue be used. The use of inappropriate materials to clean the lens or window can
permanently damage the surface and reduce the clarity.
24. System limitations
This section outlines some system limitations that exist in the CCFC camera.
24.1 High resolution 5 megapixel photos
The capturing of 5 Megapixel (MP) pictures results in longer capture times than other photo
resolutions. When a 5 MP photo is captured, the continuous video stream is paused, the photo
sensor is reconfigured, and then the 5MP photo is captured. This longer delay time would be
noticeable when capturing photos from the external trigger. 5 MP photos would take several
seconds from the external trigger signal being asserted. All other still photo captures are less
than 1 second.
24.2 Simultaneous processes
The CCFC cannot capture two events simultaneously. For example, the CCFC cannot capture a
photo while video is being recorded. Also, other processes such as downloading files from the
camera memory can add additional delays to the capture process.
