Usage Precautions
Notes on cable configurations
The presence of lighting equipment and television receivers nearby may result in video noise.
In such cases, change the cable configurations or placement.
Notes on attaching the lens
Avoiding dust particles
When attaching the lens to the camera, stray dust and other particles may adhere to the sensor surface
and rear surface of the lens. Be careful of the following when attaching the lens.
• Work in a clean environment.
• Do not remove the caps from the camera and lens until immediately before you attach the lens.
• To prevent dust from adhering to surfaces, point the camera and lens downward and do not allow the
lens surface to come into contact with your hands or other objects.
• Always use a blower brush to remove any dust that adheres.
Never use your hands or cloth, blow with your mouth, or use other methods to remove dust.
Phenomena specific to CMOS image sensors
The following phenomena are known to occur on cameras equipped with CMOS image sensors.
These do not indicate malfunctions.
• Aliasing
When shooting straight lines, stripes, and similar patterns, vertical aliasing (zigzag distortion) may appear
on the monitor.
• Blooming
When strong light enters the camera, some pixels on the CMOS image sensor may receive much more
light than they are designed to hold, causing the accumulated signal charge to overflow into surrounding
pixels. This “blooming” phenomenon can be seen in the image, but does not affect the operation of the
camera.
• Fixed pattern noise
When shooting dark objects in high-temperature conditions, fixed pattern noise may occur throughout
the entire video monitor screen.
• Defective pixels
Defective pixels (white and black pixels) of the CMOS image sensor are minimized at the factory according
to shipping standards. However, as this phenomenon can be affected by the ambient temperature,
camera settings (e.g., high sensitivity and long exposure), and other factors, be sure to operate within the
camera’s specified operating environment.
Notes on exportation
When exporting this product, please follow the export regulations of your country or region.
Notes on temperature conditions
The guaranteed operating temperature and humidity of this camera are -5℃ to +45℃, 20% to 80%
(non-condensing). Please make sure the following temperature condition is met when operating the unit.
1) The camera's internal temperature sensor detects temperatures of 98.8°C or less during operation.
If the above temperature conditions are exceeded, take measures to dissipate heat according to your
installation environment and conditions.
Depending on the operating environment, the surface of the camera
may become very hot during operation.
Do not touch the camera during operation and while it is being cooled.
Also, make sure that the cable surface and other easily deformable
items do not contact the surface of the camera.
