Home System Configuration
When configuring a home VDP system, all devices should first be connected together. Usually, this is done by connecting both the
camera unit (VTO) and monitor unit (VTH) to the VTNS1060A PoE switch.
The VTNS1060A is a 24v passive PoE unit, this is a different type of PoE than that seen on conventional IP devices. As such, both the
VTO2000A and VTH1550CH can only be used with 24v passive PoE or by connecting a 12/24vdc power supply to the power input
terminals on the units.
