4 Inch Speed Dome Installation Manual V2.0.0
The alarm provides the relay output (no voltage), and the external power supply is required when it connects to the alarm device. For
DC power supply (left diagram), the input voltage must be within the range of 12VDC, 30mA. For AC power supply, the external relay
must be used (right diagram) so as to prevent damages to the unit and avoid risk of electric shock.
