Power on the Device
⚫
Ensure that the NVR is correctly connected to a power supply, and a display is
correctly connected to the high-definition multimedia interface (HDMI) or video
graphics array (VGA) port of the NVR before power-on.
⚫
In some environments, abnormal power supply may cause the failure of the NVR to
work properly and even damage the NVR in severe cases. It is recommended to use
a regulated power supply to power the NVR in such environments.
After the NVR is connected to a power supply, the power indicator is steadily on. Start the NVR.
The real-time video screen is displayed as shown in Figure 4-1.
