2 Basic Operations
2.1 Startup
Ensure that a power supply is connected to the NVR correctly.
Before starting the NVR, ensure that a monitor is connected to the HDMI or VGA
interface of the NVR correctly.
The NVR may not operate normally when a power supply exception occurs, likely
causing damage to the NVR in serious conditions. In such a circumstance, you are
advised to use a regulated power supply.
The power indicator is steady on when the NVR is started. Then the NVR conducts a
self-test and then displays the result on the screen, as shown in Figure 2-1. The startup
process takes about 2 minutes.

When an abnormality is detected and the self-test screen stays on, choose to continue or
shut down in the lower right corner of the screen. If you choose to continue, the NVR
enters the login interface.
The hard disk(s) required by the NVR must be provided by users. Hard disk detection is
performed during startup. If the detection fails, check whether it is caused by the following
causes:
The hard disks are new and unformatted. In this case, format the hard disks based on
Chapter 3 "Quick Setup".
The hard disks are formatted, but the file system is inconsistent with the one supported by
the NVR.
The hard disks are damaged.
2.2 Shutdown
To shut down the NVR after logging in to the main interface, click in the upper
right corner. The shutdown interface appears, as shown in Figure 2-2.

2.5 Adding Webcams
PoE
After the PoE network interfaces are connected to IP cameras, the NVR automatically
adds the IP cameras and enables 7*24 recording.
Figure 2-5 shows the network topology of the NVR.
Figure 2-5 Network topology of the NVR
Non-PoE
A free network includes other network devices in addition to IP cameras and NVRs.
The topology of a free network can be organized freely so long as NVRs and IP
cameras can communicate with each other smoothly.
When a free network is used, the user needs to manually search for and add IP cameras.
For details, see Chapter 3 "Quick Setup".
Figure 2-6 shows the topology of a free network.
