Overvoltage Category according IEC 60950-22
Mains-operated outdoor equipment shall be suitable for the highest Overvoltage Category
expected in the installation location. The Overvoltage Category for outdoor equipment can be
higher than for indoor equipment. This outdoor enclosure and the internal camera equipment
is designed for overvoltage category II.
The installer is required to provide additional protection to reduce the overvoltage if the
equipment is subject to transient overvoltages exceeding those for Overvoltage Category II.
It is permitted to include protection components within the outdoor equipment. Components
used to reduce the Overvoltage Category, Surge Protection Devices (SPD), shall comply with
the requirements of IEC 61643-series or equivalent standards.
NOTE: The Overvoltage Category of outdoor equipment is normally considered to be one of
the following:
● if powered via the normal building installation wiring, Overvoltage Category II;
● if powered directly from the mains distribution system, Overvoltage Category III;
● if at, or in the proximity of, the origin of the electrical installation, Overvoltage Category
IV.
Protection against lightning strikes (direct and indirect)
Additional protection is also required for protection against direct or indirect lightning strikes
according the IEC 62305 series standards, or equivalent standards.
Consideration shall be given to the following:
● The use of properly earthed air-termination rods for pole-mounted or high-mounted
cameras
● Avoid wiring loops
● Locate protection devices close to the protected equipment (within 0.5 m)
● Keep wiring to protection devices short.

Cautions
Handle the camera carefully
Do not abuse the camera. Avoid bumping and shaking. The camera can be damaged by
improper handling or storage.
Do not disassemble the camera
To prevent electric shock, do not remove screws or covers. There are no user serviceable
parts inside. Consult technical support if a camera is suspected of malfunctioning.
Do not block the cooling vent
This camera has a cooling fan inside. Blocking the cooling holes may lead to overheating and
cause malfunction. Overheating is not covered by warranty.
Never face the camera towards the sun
Do not aim the camera at bright objects. Whether the camera is in use or not, never aim it at
the sun or other extremely bright objects, as this can damage the camera.
