2. Setup
2.1 Unpacking and Initial Inspection
Carefully unpack all components and verify that all items listed in the 'What's in the Box' section are present. Inspect the camera for any signs of damage. If any components are missing or damaged, contact Lorex support immediately.
2.2 Wired Connection
The LNB9393 camera utilizes a wired Ethernet connection for both power and data (Power over Ethernet - PoE). A CAT5e/CAT6 cable (not included) is required for connection to a compatible Network Video Recorder (NVR) or PoE switch.
- Connect one end of the Ethernet cable to the camera's Ethernet port.
- Connect the other end of the Ethernet cable to a PoE port on your NVR (e.g., Lorex N883/N882/N881 Series NVRs) or a PoE switch.
- Ensure the NVR or PoE switch is powered on. The camera will receive power and establish a network connection automatically.
2.3 Mounting the Camera
The camera is designed for both indoor and outdoor use and can be mounted on a ceiling or wall. Use appropriate screws and anchors for your mounting surface to ensure a secure installation.
Figure 2: Example of camera mounting on a wall.
2.4 NVR and App Configuration
Refer to your NVR's instruction manual for initial setup and adding new cameras. Once connected to the NVR, download the Lorex app from your device's app store to access live view, recordings, and settings remotely.

4.2 Cleaning
To maintain optimal image clarity, periodically clean the camera lens with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could scratch the lens or housing.
5. Troubleshooting
5.1 No Video Feed
- Verify the Ethernet cable is securely connected at both the camera and the NVR/PoE switch.
- Ensure the NVR or PoE switch is powered on and functioning correctly.
- Check the network connection status on your NVR for the specific camera channel.
5.2 Poor Image Quality
- Clean the camera lens to remove any dirt or smudges.
- Ensure there are no obstructions in the camera's field of view.
- Check the camera's settings on your NVR or Lorex app to ensure it is configured for 4K resolution.
5.3 Motion Detection Issues
- Review the motion detection settings in the Lorex app or NVR interface.
- Adjust motion sensitivity and define specific motion zones to optimize detection.
- Ensure the camera's view is clear of moving objects that could cause false alerts (e.g., tree branches).
