2. Typical Sensor Characteristics
The following effects may be observed on the video monitor screen. They do not indicate any fault
of the camera, but are associated with typical sensor characteristics.
V. Aliasing
When the CMOS camera captures stripes, straight lines or similar sharp patterns, jagged edges may
appear on the monitor.
Blemishes
All cameras are shipped without visible image sensor blemishes.
Over time some pixel defects can occur. This does not have a practical effect on the operation of
the camera. These will show up as white spots (blemishes).
Exposure to cosmic rays can cause blemishes to appear on the image sensor. Please take care to
avoid exposure to cosmic rays during transportation and storage. It is recommended using sea
shipment instead of air flight in order to limit the influence of cosmic rays on the camera. Pixel
defects/blemishes also may emerge due to prolonged operation at elevated ambient temperature,
due to high gain setting, or during long time exposure. It is therefore recommended to operate the
camera within its specifications.
Patterned Noise
When the sensor captures a dark object at high temperature or is used for long time integration,
fixed pattern noise may appear on the video monitor screen.
3. Caution when mounting a lens on the camera
When mounting a lens on the camera dust particles in the air may settle on the surface of the lens
or the image sensor of the camera. It is therefore important to keep the protective caps on the lens
and on the camera until the lens is mounted. Point the lens mount of the camera downward to
prevent dust particles from landing on the optical surfaces of the camera. This work should be done
in a dust free environment. Do not touch any of the optical surfaces of the camera or the lens.
4. Caution when mounting the camera
When you mount the camera on your system, please make sure to use screws of the
recommended length described in the following drawing. Longer screws may cause serious
damage to the PCB inside the camera.
If you mount the tripod mounting plate, please use the provided screws.
