Wiring and Installation
There are several ways to install the speed dome. The wall mounting is taken as an example below.
2.3.1
Wiring
The survey of the actual installation environment and planning the wiring is highly recommended
before the accurate deployment of the wire is implemented in order to provide a safe and steady
power supply and a reasonable wiring route.
Get familiar with the installation environment before deploying the wire, including the wiring
distance, surrounding, and electromagnetic interference and so on.
Please choose the cable with nominal voltage higher than the actual voltage, to ensure a
normal running in case of unsteady voltage.
To protect the power cable and the signal transmitting cable from human tampering, you
should pay attention to the protection and reinforcement of the cables.
When deploying the wire, please do not tighten the wire or make the wire loose.
The wiring of the speed dome should be performed by professionals.
