to exposure of product in the wrong conditions will be user‟s responsibility.
7. Indoor Dome Camera cannot be installed at rainy or wet places. If the Indoor Dome Camera has a
connecting rod on the bracket, make sure there is no hole on the rod to avoid water.
8. Outdoor Dome Camera must be completely sealed to avoid dampness. Make sure there is no hole
on the connecting rod of bracket to avoid water.
9. While shipping the camera, pack it in the factory packing or use materials with equivalent quality.
10. When it is necessary to replace a part, please contact your dealer in advance and replace the part
with specified model or part of the same features. We shall not assume any responsibility for
problems caused by unauthorized replacement.
11. Do not shield the sensor at front of the lens housing.
12. When power off the camera, reboot it after 30 seconds.
Anti-thunder and Anti-surge
The camera adopts built-in anti-thunder technology and can withstand instant 4KV thunder when it is
well grounded. To prevent damage caused by thunders exceeding the built-in anti-thunder level, an
independent anti-thunder engineering must be carried out. When installing it outdoor, please note the
following tips to reduce damage efficiently such as thunder.
1. The distance between the signal wire and the high-tension apparatus or high voltage cable should
be at least 50m.
2. Try to route cables along the eave when installing outdoor.
3. When installing camera in an open field, route cables inside sealed steel pipes under the earth and
ground the pipes with one point. Never route cables in aerial way.
4. In heavy thunderstorm area or high-tension zone (such as high voltage transformer substation), an
extra superpower anti-thunder apparatus and lightning rod must be installed.
5. The anti-thunder and grounding design of outdoor apparatus and wires must consider the
anti-thunder requirements of the building and conform to the requests of national and industrial
standards.
6. The system must be grounded with equipotential. The grounding apparatus must be
anti-interference and electrically safe. It cannot be short-circuited or hybrid connected to the null line
of high-
voltage power grid. When it is grounded independently, the ground impedance is ≤4Ω and
the earth lead section surface must be ≥25mm
2
.
7.
The anti-thunder grounding wire of the dome camera uses multi-strand copper cable with section
surface ≥4mm
2
(strand diameter
about ≥2.3mm).
