2.4. Power supply availability
EPoC equipment supports PoC (Power over Coax), so that the transmitter and the end-device (e.g. camera) are
powered by receiver.
When installing multiple cameras over one cable with daisy chain configuration or PTZ camera with high power
consumption, it is possible to configure by putting an additional power adapter (48 ~ 57VDC) on the transmitter.
Examples of using additional adapters
█
• When installing two cameras with high power consumption such as 30W by 2:1 Daisy chaining, two power adapters
of 56VDC /1.2A can be applied on the transmitters and the maximum 120W power is supplied throughout the
whole range.
• The power adapter can be applied to transmitter or receiver or both transmitter and receiver simultaneously.

NOTE:
- To avoid damage of products do not connect Transmitter RJ45 PoE Out to a PoE Switch!
- Joining function by hardware is only available between Transmitter/Receiver or
Transeiver devices except camera.
2.5. Site environment review
• Check the environment in which EPoC device is installed.
• The cable between the EPoC devices must be installed apart from high-voltage power cable.
• In environments where cross-talking or signal interference occurs, separate settings may be required, such as
network grouping (See how to set Joining).
• In environments where power noise occurs (e.g. Installation on elevator), it is necessary to use a model
specifically designed to prevent noise.
• EPoC devices are for Indoor Use and must be installed in a separate watertight enclosure when installed
outdoors.
• Check that the environment is suitable for the operating temperature and operating humidity of the equipment.
