cleaning the lens.
Phenomena Specific to CMOS Image Sensors
0
The following phenomena that may appear in images are specific to CMOS (complementary metal-
oxide semiconductor) image sensors. They do not indicate malfunctions.
0
White Spots
Although the CMOS image sensors are produced with high-precision technologies, fine white spots
may be generated on the screen in rare cases, caused by cosmic rays, etc. This is due to the principle
of CMOS image sensors and is not a malfunction. The white spots tend to be seen especially in the
following cases:
- When operating at a high environmental temperature
- When the shutter speed is slowed down
- When you have raised the master gain (sensitivity)
0
Aliasing
When fine patterns, stripes, or lines are shot, they may appear jagged or flicker.
Others
0
For safety and power saving purposes, turn off the system when it will not be used for a long time.
0
This unit is a precision instrument, do not subject to strong impact.
0
This unit is designed to be used indoor. Be sure to take protective measures such as attaching a
protective cover when using it outdoor.
0
We recommend that a cable connected to the DC power terminal and RS-485 port be 3 meters or less.
0
When installing the lens, take care to prevent dust or dirt from getting inside. Also, be careful not to touch
