EMC
The equipment has been tested and found to meet the CE-regulations relating to EMC, and
complies with the limits for a Class B device, pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection against interference to radio communications in
any installation. The equipment generates, uses, and can radiate radio frequency energy;
improper use or special circumstances may cause interference to other equipment or a
performance decrease due to interference radiated by other equipment. In such cases, the user
will have to take appropriate measures to reduce such interactions between this and other
equipment.
Any interruption of the shielding inside or outside the equipment could make the equipment
more prone to fail EMC requirements.
Non-video signal lines must use appropriate shielded Cat 5 cabling (S-FTP), or at least an
equivalent. Ensure that
all electrically connected components are carefully earthed and
protected against surges (high voltage transients caused by switching or lightning).
ESD
Electrostatic discharge (ESD) can damage or destroy electronic components. Proper precautions
should be taken against ESD when opening the equipment.
2.2 Cautions
Handle the camera carefully.
Do not abuse the camera. Avoid striking, shaking, etc. as the camera can be damaged by
improper handling or storage.
Install electrical wiring carefully.
Ask a qualified electrician to perform the wiring for the installation. Please note that input
electricity to the unit is at a tolerance of 24VAC 50/60 Hz ± 10%. Ground the camera
appropriately to prevent electric shock or damage.
Power input: 3-pin terminal block
Do not disassemble the camera.
To prevent electric shock, do not remove screws or covers. There are no user serviceable parts
inside. Please consult technical support if a camera is suspected of malfunctioning.
Do not operate the camera beyond the specified temperature,
humidity, and power source ratings
Use the indoor camera under conditions where the temperature is between 0°C~40°C
(32°F~104°F).
Do not use strong or abrasive detergents when cleaning the
camera.
Use a dry cloth to clean the camera when it is dirty. If the dirt is hard to remove, use a mild
detergent and wipe gently. To clean the lens, use lens tissue or a cotton tipped applicator and
ethanol. DO NOT clean the lens with strong detergents.
