Quick Fix Checklist (Start Here)

  • Power: Confirm the included power cable is firmly connected to the NVR / a working outlet and that the power switch is turned to ON.
  • Display: Confirm the monitor / TV is set to the correct input (HDMI or VGA) and the cable is fully seated on both ends.
  • Cameras: Verify each camera Ethernet cable is firmly connected to a built-in PoE port, router, or PoE switch as applicable.
  • Network: Confirm the router cable is connected to the NVR WAN port.
  • Storage: If you’re missing recordings, confirm the HDD is detected, formatted, and recording is enabled.
Tip: If the NVR is responsive but behaving unexpectedly, reboot it from Main Menu > Settings > System > Maintenance.

Forgot NVR Password

If you forget your NVR password, you can reset it using one of the options set up during installation.

Security Questions: From the NVR login screen, select Forgot Password and answer one of the security questions you created during setup. If the answer is correct, you’ll be able to create a new password.

Email Verification: You can also reset your password through the Lorex Connect app if your NVR is already connected to the network and linked to the app. Open the Lorex Connect app, select your NVR, then go to Settings > Help > Reset Device Password. Tap Get Verification Code, check your email for the code, enter it in the app, and follow the prompts to create a new NVR password.

Important: If your NVR is not linked to the Lorex Connect app and you cannot answer your security questions correctly, you will permanently lose access to your system. For your privacy and security, Lorex Technical Support cannot reset, recover, or bypass your NVR password.

To help prevent losing access, store your security question answers in a safe place and link your NVR to the Lorex Connect app during setup.

NVR does not power on

  • Verify the included power cable is securely connected to the NVR and a working outlet.
  • Try a different outlet or surge protector.

  • Disconnect non-essential accessories (USB devices, cameras, external storage) and try powering on again.
Note: Always use the power cable supplied with the recorder.

No video signal / display output issues

  • Check that the HDMI or VGA cable is securely connected to both the NVR and the monitor / TV.
  • Make sure your monitor input matches the connection you are using.
  • If the screen is blank or unsupported, lower the output resolution.

To change output resolution: Right-click twice in Live View > Main Menu > Settings > System > General > System > Output Resolution.

Output Resolution

Tip: If Auxiliary Screen is enabled, the VGA output uses its own settings under System > Auxiliary Screen.

Camera not showing / offline

  • For cameras connected to built-in PoE ports, make sure the Ethernet cable is firmly connected and wait 30 to 60 seconds for the camera to initialize.
  • Check the camera’s connection status in the camera list (Main Menu > Settings > Channel > Camera)
  • Verify the channel status in Main Menu > Settings > System > Information > Channel.
  • If needed, try a different PoE port or Ethernet cable.

How do I connect compatible Lorex IP cameras to an X Series NVR using ONVIF?

Some compatible Lorex IP cameras can be connected to an X Series NVR using the ONVIF protocol. Before adding the camera to the recorder, some camera models must first be initialized through the camera’s web interface.

In general, setup includes connecting the camera to your local network, finding the camera’s IP address, initializing the camera, creating an admin password, and then connecting the camera to an available PoE port on the back of the NVR.

Note: For full step-by-step instructions, including how to initialize the camera and check the camera status on the NVR, see How to Connect Compatible Lorex IP Cameras to an X Series NVR Using ONVIF.
Important: Before setup, check the Lorex Compatibility Chart to confirm that your camera model supports connection to an X Series NVR.

What cameras are supported?

This recorder is designed for compatible IP cameras. Cameras can be connected directly to the recorder’s built-in PoE ports or through your local network using a router or PoE switch. The recorder supports up to 16 channels total.

The recorder also supports common network interoperability features such as ONVIF and RTSP.

For the best results, check the Lorex Compatibility Chart and look up your camera model to confirm compatibility before connecting it to the NVR.

Tip: To take advantage of full 4K recording, use compatible 4K (8MP) IP cameras. If you’re mixing camera models, always verify each one in the compatibility chart first.

How do I add the NVR to the Lorex Connect app?

  1. Download and open Lorex Connect for Android or Lorex Connect for iPhone.
  2. Create an account or log in.
  3. Tap + Add device and select Recorder.
  4. Keep your phone and NVR on the same network during setup.
  5. Enter your NVR password to complete pairing.

If the app cannot find the recorder automatically: In the app, tap My recorder is on a different network than my Lorex Connect app. On the recorder, go to Main Menu > Settings > System > Lorex Connect, then scan the QR code shown on the recorder screen and follow the in-app steps.

Note: For remote viewing from the app, keep the NVR wired to the router.

How do I access the recorder in a web browser?

You can access the recorder from a web browser on the same network.

  1. Open Google Chrome.
  2. Enter the recorder’s IP address in the address bar, then press Enter.
