3. الإعداد
Follow these steps to set up your HaiweiTech H.265 HDMI CVBS Decoder:
- توصيل الطاقة: Connect the provided 12V 2A power adapter to the DC 12V input port on the decoder and plug it into a power outlet. The red LED indicator should illuminate.
- إتصال شبكة: Connect an Ethernet cable from your network (router or switch) to the LAN port on the decoder. Ensure your network provides access to the IP video streams you intend to decode. The green LED indicator should illuminate, indicating network activity.
- Video Output Connection:
- For HDMI output, connect an HDMI cable from the HDMI OUT port on the decoder to the HDMI input of your display (monitor, TV, projector).
- For CVBS output, connect a BNC cable from the BNC OUT port to your display's BNC input, or use the AV OUT port with the provided AV cable for composite video and analog audio.
- وصول Web الواجهة: The decoder typically obtains an IP address via DHCP. To find its IP address and configure settings, you may need to use an IP scanner tool or refer to your router's connected devices list. Once the IP address is known, open a web browser and enter the decoder's IP address to access its webواجهة التكوين المستندة.
- Configure IP Stream: ضمن web interface, navigate to the input settings. Enter the full RTSP, RTMP, HTTP, HLS, or UDP stream URL, including any necessary username and password. Ensure the syntax is correct.

This diagram illustrates how the decoder fits into a larger video system, receiving streams from an encoder via a network and outputting to a local display or user device.
4. تعليمات التشغيل
Once the decoder is set up and configured with the correct IP stream, it will automatically begin decoding and outputting the video and audio to the connected display(s).
- Single Channel Decoding: For single stream decoding, ensure only one IP stream URL is configured as active in the web interface. The decoder will output this stream to both HDMI and CVBS simultaneously.
- متعددView فك التشفير: The decoder supports multi-view decoding for up to 4 channels (2*1080P + 2*720P). Configure multiple stream URLس في web interface and select the multi-view layout option if available. The decoder will combine these streams into a single output display.
- الدقة ومعدل الإطارات: The decoder will attempt to output the stream at its native resolution and frame rate, up to the maximum supported by the device (4K@30FPS). Ensure your display supports the output resolution.
- مخرج الصوت: Audio embedded in the IP stream will be output via HDMI and the analog AV OUT port.
- التحكم RS485: If applicable, connect RS485 devices for external control or data communication as per your system requirements.
