3. Setup

3.1 Physical Connections

1. Connect HDMI Source: Connect your HDMI video source (e.g., camera, computer, set-top box) to the HDMI IN port on the encoder using an HDMI cable.
2. Connect Audio Source (Optional): If using an external audio source, connect it to the AUDIO IN port. Otherwise, audio will be extracted from the HDMI input.
3. Connect to Network: Connect the LAN port of the encoder to your network router or switch using an Ethernet cable.
4. Power On: Connect the 12V DC power adapter to the DC 12V port and plug it into a power outlet. The device will power on automatically.

3.2 Network Configuration

After physical connections, the encoder will obtain an IP address via DHCP by default. To access the web-based management interface:

1. Ensure your computer is on the same network as the encoder.
2. Use a network scanning tool (e.g., IP Scanner) to find the encoder's IP address on your network. The default IP address is often 192.168.1.168, but this can vary based on your network's DHCP server.
3. Open a web browser and enter the encoder's IP address in the address bar.
4. Log in using the default credentials (refer to the included quick start guide for default username and password).

Important: For security, it is highly recommended to change the default password immediately after the first login. You may also configure a static IP address if required for your network setup.

3.3 Connection Diagrams

4. Operating Instructions

The encoder's functions are managed through its web-based interface.

4.1 Status Monitoring

The "Status" page provides real-time information about the device's operation, including running time, CPU usage, memory usage, codec usage, video size, collected frames, and network packet statistics. This page is crucial for verifying input signal and stream health.

4.2 Video Stream Settings

Navigate to the "Encoder" section to configure video parameters for the main stream and substreams.

• Encoding Type: Select H.264 or H.265.
• Encoded Size: Choose the output resolution (e.g., 3840x2160, 1920x1080, 1280x720).
• FPS (Frame Rate): Set the desired frame rate.
• Bitrate Control: Select VBR (Variable Bit Rate) or CBR (Constant Bit Rate).
• Bitrate (kbit): Adjust the video bitrate. Higher bitrates generally result in better quality but require more bandwidth.
• Streaming Protocols: Enable and configure the desired streaming protocols (RTSP, RTMP, HLS, UDP, SRT, etc.) for each stream.
