よくある質問

Q: Why does the image of my USB video to CVBS PAL video encoder board stay green?
A: A green image usually indicates no signal input or that the device is in standby mode. Please check the following:

1. Ensure that your source device is powered on and properly connected.
2. Verify that the signal cable (例えば, USB) is not too long or damaged, as excessive length may cause signal interruption.
3. Try using a shorter or different cable to see if the issue persists.
4. Test via network output: Our USB to CVBS encoder board also supports network video streaming. You can connect it to a network cable and use a VLC player to view the video stream. If the video stream is normal, the issue is likely in the CVBS output or connection. If the stream is still green, the problem is likely with the input signal.

Q: What frame rate does the USB to CVBS converter board use when opening the camera?
A: デフォルトでは, the board opens the camera at 1920 × 1080 resolution with 30 fps (1080P@30fps).
If the camera’s maximum supported resolution is lower than 1080P, the board will automatically open the camera at the highest resolution supported by the camera.

Q: Does the board generate log files that customers can upload for troubleshooting?
A: The board does not generate detailed log files for upload.
For troubleshooting and debugging, あなたはできる connect through the serial port (UART) to obtain the boot/startup logs, which can then be shared with our support team for analysis.

Q: What should I pay attention to during firmware upgrade? Can the device be recovered if the upgrade fails?
A:The device must remain continuously powered during the entire firmware upgrade process. Any interruption—such as power loss, cable disconnection, or system shutdown—may result in firmware corruption and cause the device to stop functioning.

Due to the built-in hardware security mechanism (encrypted authentication), firmware recovery in such cases is extremely difficult and may not be possible without original factory-level tools and authorization. Replacing or reprogramming the chip will not resolve the issue. To avoid this risk, please ensure a stable power supply and do not interrupt the upgrade process under any circumstances.

Q: Can this board support MIPI camera input with CVBS output?
A: The board includes a MIPI interface and can be customized to support MIPI camera input with CVBS output. しかし, this function is not standard and requires custom hardware configuration as well as dedicated driver and image processing software development based on the specific camera module. To proceed, we must know the exact MIPI camera model you intend to use (including sensor type, 解決, and MIPI interface specifications), as the driver must be developed specifically for that camera.

Q: What type of USB cameras are supported?
A: The converter supports UVC準拠のUSBカメラ, including standard visible-light USB cameras and compatible thermal imaging cameras.

第2四半期: What analog video formats are supported?

A: The board outputs CVBS (コンポジットビデオ) そして両方をサポートします NTSC and PAL 標準.

Q3: Does it require drivers or software?

A: いいえ. Standard UVC cameras are automatically recognized, and video is converted to CVBS output in real time.

Q4: Can I switch between NTSC and PAL?

A: はい. The output video standard can be selected based on system or regional requirements.

Q5: Can I connect more than one USB camera?

A: いいえ. システムがサポートする only one USB camera input. USB hubs or multiple camera switching are not supported.

Q6: Can this module output HDMI or IP video?

A: This model is designed specifically for USB to analog CVBS and IP Ethernet video conversion.

Q: What is the video delay (レイテンシ) of this USB to CVBS converter?

A: The video delay of this USB to CVBS converter board is approximately 100 ミリ秒. This ultra-low latency ensures smooth and real-time analog video output from a USB camera, making it ideal for applications such as FPVドローン, 産業用監視, DVR systems, and embedded video solutions.

Q: Does the USB-to-CVBS module provide vibration damping or image stabilization for vehicle applications?

A: いいえ. This module is only a USB video to CVBS conversion board. It does not perform any image processing.

Specifically:

• The module outputs exactly the same image it receives from the USB camera.

• No vibration damping, no electronic image stabilization (EIS), そして no image correction are applied.

• If the camera image contains vibration or shaking (for example, when installed on a moving vehicle), this vibration will also appear in the CVBS output.

If vibration reduction is required, it must be handled by:

• A USB camera with built-in optical or electronic stabilization, または

• アン external image processing system before the USB video is fed into this module.

The USB-to-CVBS board itself functions purely as a video format converter, not an image enhancement or stabilization device.

Q: What remote access and software customization options are supported?

A: The device supports Telnet access, しかし does not support SSH. SDK-based secondary development is not supported, and customer-side software development is not open.

のために general software requirements or standard functional modifications, customers only need to provide detailed specifications. Our engineering team will implement the required changes directly after technical evaluation. No SDK development or programming is required from the customer.

Q: How to upgrade the firmware?
A: To install or apply the update, use our IPC Search Windows Tool by following these steps:

1. Install and launch IPC Search on a Windows PC.
2. Connect the device to the same network as the PC.
3. Use IPC Search to detect the device.
4. Load the provided upgrade package into the tool.
5. Execute the upgrade process via IPC Search.

Download link, IP Search Tool no Linux, only Windows OS.

You can use this software to perform various functions, 含む: Setting the gateway, Modifying the IP address, Configuring the P2P server, Performing software upgrades, And other device management tasks.

Q: Why can my USB to CVBS encoder be discovered by the IPC search tool, but I still cannot open the web management page in the browser even after entering the correct IP address?

A: Based on the images you provided, the USB input is not connected to a camera. When there is no valid USB video source connected, the encoder cannot detect an input signal. 結果として, the device will continuously reboot while attempting to identify a USB signal source.

Please connect a USB camera to the encoder. Once a valid video input is detected, the device will operate normally and you will be able to access the web management page through the browser to modify parameters.

Q: How can I remove the time watermark displayed in the top-right corner of the network video stream?

A: Please log in to the web management page of the encoder.
に行きます Audio and Video tab, then find OSD Settings.
で Display Time オプション, uncheck the box to disable it.

After saving the settings, the time watermark will no longer be displayed in the video stream.

Q: What is IR_CUT mode?
A: IR_CUT mode supports external IR LED lights. Our encoder board can control external infrared LEDs to enhance the camera’s illumination, improving visibility in low-light or nighttime conditions. It also enables automatic switching between color (day) and infrared (night) モード, allowing the camera to provide clear images in both bright and dark environments.

Q: Besides the USB to CVBS card, what other analog video outputs are supported? Does it support AHD?
A: 現在, this device only supports CVBS (パル/NTSC) output and IP Ethernet RTSP video streaming. AHD, TVI or other analog video outputs are not supported.
