4. Setup and Installation
4.1 Choosing the Right Lens Distance
The camera offers various lens options (2.8mm, 3.6mm, 6mm, 8mm) which affect the viewing angle and effective distance. Refer to the table below to select the appropriate lens for your surveillance needs:

4.2 Installation Methods
The camera supports two main power configurations: DC 12V (Camera Only) and 48V Power over Ethernet (PoE).
4.2.1 DC 12V Installation (Camera Only)
This method requires a separate DC 12V power adapter (not included). Connect the camera to your network router and NVR as shown in the diagram.

4.2.2 48V PoE Installation
For PoE-enabled cameras, power and data are transmitted over a single Ethernet cable. This requires a PoE switch or NVR with PoE capabilities. No separate power adapter is needed for the camera itself.

Note: The PoE Camera variant includes a PoE splitter (Model: PD-4812, Input: 48V, Output: 12V 2.0A, Agreement: IEEE802.3af/at) for power delivery.

5. Operation
5.1 Remote Viewing
The camera supports real-time viewing from multiple devices, including mobile phones (Android, iOS) and computers (Windows 8, Windows 10). You can access live video and audio from anywhere in the world via the mobile app (Linklemo APP) or PC software.


5.2 Two-Way Audio
The built-in microphone and speaker enable two-way audio communication, allowing you to listen and speak through the camera.

5.3 Night Vision Modes
The camera features Smart Dual Light Source technology with both white LED and infrared (IR) LED lights, offering three distinct night vision modes:
- Full-color mode: The APP can be set with a white light (always on) to monitor and display a full-color picture, which can also be used as a lighting lamp.
- Infrared night vision: The fill light is turned off, the infrared light is turned on, and the monitor is displayed in black and white.
- Intelligent night vision: The default is black-and-white night vision. When a human figure is detected, it will automatically switch to full-color night vision.



The camera's night vision range is up to 20-30 meters in dark conditions.
5.4 Advanced Image Technologies
- HDR (High Dynamic Range): Improves brightness and contrast, enriching details in both dark and bright areas for a more realistic image.
- 3DNR (Digital Noise Reduction): Filters out noise in low-light conditions and motion, providing a cleaner and more accurate image.


6. Maintenance
The camera is designed for durability and minimal maintenance. Its IP66 weatherproof rating ensures protection against dust and water jets, making it suitable for various environmental conditions.
- Cleaning: Gently wipe the lens and camera body with a soft, damp cloth. Avoid harsh chemicals or abrasive materials.
- Environmental Conditions: The camera operates effectively in temperatures ranging from -10°C to 60°C and humidity up to 95% (non-condensing). Ensure the camera is installed within these conditions for optimal performance and longevity.
- Firmware Updates: Periodically check the manufacturer's website or your camera's app for available firmware updates to ensure the best performance and security features.

7. Troubleshooting
- No Power: Ensure the power adapter (for DC 12V models) is correctly connected and the outlet is functional. For PoE models, verify the PoE switch/NVR is providing power and the Ethernet cable is securely connected.
- No Video Feed: Check network connectivity. Ensure the camera is properly connected to the router/NVR. Verify IP address settings and firewall configurations.
- Poor Image Quality: Clean the camera lens. Ensure sufficient lighting for optimal night vision. Adjust camera position to avoid glare or obstructions.
- Audio Issues: Check microphone and speaker settings in the app/software. Ensure volume levels are appropriate.
- Remote Access Failure: Verify internet connection on both the camera and viewing device. Check router settings for port forwarding if necessary, or ensure P2P service is active.
