2 Installation
2.1 Coaxial Control
The dome supports coaxial control and also supports RS-485 communication signal.
2.1.1 AC24V power cable transmission distance and cable requirement
In general, the power cable has resistance, there are internal losses when transmitting the
voltage, the longer of the cable used, the smaller the wire diameter, the worse loss will suffer.
In order to avoid losses of cable causing low voltage and keep the dome work properly,
when processing wiring please refer to the requirement below:
Cable diameter 0.5mm
²
(20#) 1.0mm
²
(18#) 1.5mm
²
(16#) 2.5mm
²
(14#)
Dome distance
11m(37ft)
18m(60ft)
29m(95ft)
46m(152ft)
For example, if a dome is 35 meters away from the power supply , power cable used must
be more than 2.5mm
²
, otherwise, the dome may suffer insufficient power supply and could
not work properly.
Remark: The dome with DC12V should be less than 3 meters away from power supply.
