1. Check Power and Physical Connections
1)Verify device power supply
Ensure the NVR and router power adapters are firmly plugged in and cables are not damaged. Check the power indicator lights. If the light is off, try replacing the power adapter.
2)Check network cable connections
Reconnect the cable between the NVR port and the router port to avoid loose or half-inserted connections.
2. Verify NVR and Router Port Functionality
1)Connect the NVR to a monitor via HDMI to check if the NVR boots up.
If it boots successfully, the NVR is working.If it fails to boot, the NVR may be faulty.
2)After connecting with a network cable, check the port indicator lights:

If the router port light does not turn on, the router may be faulty.
Try replacing the cable or router. It’s recommended to use Cat6 cable with 568B standard.
3. Check Device Compatibility
1)Verify router network mode compatibility
Access the router management page and confirm the LAN IP range is compatible with the NVR’s default IP.
Example: If the NVR default IP is 192.168.1.100 (subnet 192.168.1.X) and the router LAN IP is 192.168.2.1, change the router LAN IP to 192.168.1.1 so both are on the same subnet.
2)Note: Some NVR models (e.g., NVR2216-16P-I2) are international versions and universally compatible. NVRs do not support USB Wi-Fi adapters; only wired connections are supported.
