Figure 2-1. Camera wireless system
The power supply is applied to the WCU and via the Triax cable to the AMU. The camera is
battery (DC) powered using high-density batteries.
The OCP 400 operational control panel is connected to the WCU using a Ethernet connection.
If the OCP is connected directly to the WCU, use a crossover cable.
Triax cable
The AMU is connected to the WCU using a Triax cable. The maximum length of cable that can
be used is 600 m (1,970 ft) for a 11mm Triax cable.
The approximate maximum cable lengths between an AMU and a WCU are given in the table
below. Digital transmission will generate increasing bit errors and video may be lost when
these lengths are exceeded. The maximum length is given for cables of the highest quality.
The quality of poorer cables and the interconnections can adversely affect this maximum
length.
