Anti-Lightning, Anti-Surge; Clean Transparent Cover - Comelit DOME IR PTZ Guide D'utilisation

Anti-lightning, Anti-surge


This product is air discharge and lightning protected with TVS tube technology,
which can effectively prevent transient lightning below 6000 volts, surge and damages
caused by other types of pulse signals.

However, necessary protective measures should be made on the premise of
ensuring electrical safety for outdoor installation according to the situation :

Signal transmission line must be at least 50 meters away from any high-voltage
equipment or high voltage cables.

Overhead wiring is absolutely prohibited.

In strong thunderstorm areas or areas with high induced voltage (such as high
voltage substations), installation of additional high power lightning protection equipment
and lightning rod is essential.

Lightning protection and grounding of outdoor devices and lines must take the
lightning-protection requirements of buildings into consideration, and comply with the
related national standards and industry standards.

Grounding device must meet dual requirements of anti-interference and electrical
safety, and should not be shorted or mixed with the adjacent lines in a power grid. When
system is independently grounded, grounding impedance should be less than 4Ω, and
cross-sectional area of grounding conductors must be not less than 25mm
