5 Solución de problemas
This section provides solutions to common issues you might encounter with your Lorex NVR.
5.1 Sen saída de vídeo na pantalla
- Comproba os cables: Ensure the HDMI or VGA cable is securely connected to both the NVR and the display. Try a different cable or display if possible.
- Entrada de pantalla: Verify that your monitor or TV is set to the correct input source (e.g., HDMI 1, VGA).
- Potencia do NVR: Confirm the NVR is powered on and its power indicator light is active.
- Compatibilidade de resolución: If the display supports lower resolutions, try connecting the NVR to a different display or consult the NVR's manual for instructions on changing output resolution (if accessible).
5.2 As cámaras non mostran
- Alimentación por Ethernet (PoE): Ensure cameras are properly connected to the NVR's PoE ports. Check if the PoE port indicator lights on the NVR are active for the connected cameras.
- Integridade do cable: Inspect Ethernet cables for any damage. Try swapping cables or ports.
- Compatibilidade: This NVR is designed for use with Lorex IP cameras. Compatibility with third-party cameras is not guaranteed.
- Camera Power Cycle: Disconnect and reconnect the camera's Ethernet cable to power cycle it.
5.3 Remoto Viewing Issues (Lorex Cloud App)
- Conexión de rede: Ensure the NVR is connected to the internet via its LAN port and your router. Verify your mobile device has a stable internet connection.
- NVR Online Status: Check the NVR's network settings to confirm it has obtained an IP address and is showing as "online" or "connected" to the Lorex Cloud service.
- Substream for Remote Viewing: For optimal performance over mobile networks or slower internet connections, the Lorex Cloud app often defaults to a lower-resolution substream. This is normal behavior to ensure smooth streaming. Full 4K resolution is typically best viewed directly from the NVR's HDMI output.
- Configuración do enrutador: Ensure your router is not blocking necessary ports for the NVR's cloud connection. Consult your router's manual or ISP for port forwarding information if needed, though Lorex Cloud usually uses P2P for simpler setup.
- Wi-Fi Extenders/Mesh Networks: Some network configurations, particularly those using Wi-Fi extenders or mesh networks that suppress broadcast packets, may interfere with the NVR's ability to communicate with cameras or the cloud service. Ensure the NVR and cameras are on the same logical network segment.
5.4 Hard Drive Not Recording
- Estado do disco duro: Check the NVR's system settings to verify the hard drive status. It should be "Normal" or "Initialized". If not, you may need to format or initialize the HDD.
- Horario de gravación: Ensure the recording schedule is properly configured for continuous or motion-triggered recording.
- HDD Fault: If the hard drive is faulty, it may need replacement. Contact Lorex support for assistance.
