3.1.2 Camera Installation
When installing, the static, electromagnetic interference, lightning and surge should be considered, and
at the same time, the combined camera heat dissipation should also be concerned.
3.1.2.1 Consideration of Static, Electromagnetic Interference, Lightning and Surge
Although the camera has a lightning and anti-surge protection design, as well as EMI (Electro-Magnetic
Interference) and ESD (Electro-Static Discharge) protection design, but for security, the installation
environment and methods should be concerned to avoid or reduce these effects.
Please pay attention to basic protection methods shown below:
Use SSTP shielded network cable. If the operation requirement is satisfied, please do not
over-request the flexibility of the cable because that in order to achieve a good softness, a lot of
cables make compromises with thickness of copper wire, thickness of shielding aluminum foil,
density of shielding network and protection performance of PVC cover.
The cable should be as short as possible. If the cable is too long and remains a lot, please take the
snake-like wiring and do not wire around the cable. Such method can reduce the coupling of EMI.
Please use shielded lines as power control cord and avoid winding. The power cord and the
network cable can be run in parallel, but do not wrap them together.
Power cord and network cable should be far away from high current, high voltage, frequently
