3.2. Power and Network Connection (PoE)
This camera utilizes Power over Ethernet (PoE) for both power and data transmission, simplifying installation. A PoE injector or a PoE-enabled Network Video Recorder (NVR) is required and not included with this add-on camera.
- Connect Ethernet Cable: Connect one end of the included Cat5 Ethernet extension cable to the camera's Ethernet port.
- Connect to PoE Source: Connect the other end of the Ethernet cable to a PoE port on your NVR or a PoE injector.
- Secure Connections: For outdoor installations, ensure all Ethernet connections at the camera are properly protected from weather to prevent failure.

4. Operation
4.1. 4K Ultra HD Video
The E842CA camera features an 8MP image sensor, providing 4K Ultra HD resolution. This high resolution ensures exceptional detail and clarity in recorded footage. The increased pixel count also enhances digital zoom capabilities, allowing for clearer identification of distant objects during post-recording analysis.

4.2. Color Night Vision (CNV)
This camera is equipped with Color Night Vision (CNV) technology, which provides full-color video in low-light conditions. CNV performs optimally with ambient lighting present. In environments with total darkness, the camera will automatically switch to its infrared LEDs for clear black and white night vision footage.

4.3. Smart Motion Detection (Person/Vehicle)
The E842CA features advanced Smart Motion Detection, capable of distinguishing between people and vehicles. This technology helps reduce false alerts by only sending notifications when a person or vehicle is detected within the camera's field of view, focusing on relevant events.

4.5. Control Method
The camera can be controlled and monitored via a compatible NVR and the Lorex Connect or Lorex Classic mobile applications. These apps are available for Android devices and allow for remote viewing, playback, and configuration of camera settings.
5. Maintenance
5.1. Weather Resistance
The E842CA camera has an IP67 weatherproof rating, ensuring its functionality in extreme hot or freezing temperatures, as well as protection against dust and water ingress. This rating guarantees year-round outdoor coverage.

5.2. Cleaning and Inspection
Periodically inspect the camera lens for dirt or obstructions and clean with a soft, damp cloth. Avoid abrasive cleaners. Regularly check cable connections, especially outdoor Ethernet connections, to ensure they remain sealed and protected from moisture to prevent signal loss or damage.
6. Troubleshooting
6.1. No Video Feed
- Check Power: Ensure the camera is receiving power via the PoE connection. Verify the PoE injector or NVR port is active.
- Check Cable: Inspect the Ethernet cable for damage. Try a different cable if necessary.
- NVR Compatibility: Confirm the camera is compatible with your NVR system. Refer to your NVR's documentation.
6.2. Poor Image Quality
- Clean Lens: Ensure the camera lens is clean and free from dirt, dust, or smudges.
- Lighting Conditions: Verify adequate lighting for Color Night Vision. In very dark conditions, the camera will switch to black and white infrared.
- Network Bandwidth: Ensure your network has sufficient bandwidth for 4K video streaming.
6.3. False Motion Alerts
- Adjust Sensitivity: Reduce the motion detection sensitivity settings in your NVR or app.
- Configure Detection Zones: Set up specific detection zones to exclude areas with frequent irrelevant motion (e.g., moving trees, public pathways).
- Verify Smart Detection: Ensure Person/Vehicle detection is enabled and configured correctly.
6.4. Remote Access Issues
- Network Configuration: Ensure your NVR or camera is properly connected to the internet and network settings (e.g., port forwarding) are correctly configured if not using Lorex Cloud services.
- App Connection: Verify your mobile device has a stable internet connection and the Lorex app is updated.
