常問問題

Q: Is it possible to have a digital zoom function in this encoder?
一個: 沒有, our CVBS to Ethernet IP encoder does 不是 support a digital zoom function. This device is designed to convert analog CVBS video signals into Ethernet (即時傳輸協定) 溪流. It does not process or modify the video content itself.

Digital zoom is typically a function of the camera or the video management software (虛擬管理系統), not the encoder. 所以, if digital zoom is required, it should be implemented at the camera side or within the software used to view the video stream.

Q: Can you provide the serial port (串口) commands available for IoT?
一個: Our encoder board supports 串口 (序列埠) 資料傳輸, but it works in a transparent pass-through mode.This means the encoder does not define or generate specific UART commands itself. 反而, it simply transfers serial data between devices over the network.

The actual UART command set depends on your camera or connected device. If your camera supports serial control, those commands can be transmitted through our encoder without modification.

例如, some of our thermal imaging cameras support UART commands to adjust settings such as color palettes and zoom in levels. You can refer to this example for more details: https://ivcan.com/how-to-modify-color-zoom-of-fpv-thermal-imaging-camera

Q: Why did the image become black and white during testing, but return to color after rebooting?
一個: If the video source or camera is changed during operation, the encoder may need to restart in order to correctly detect and initialize the new video source. During this process, the image may temporarily appear in black and white. After rebooting or restarting the encoder, the system re-detects the video source and the color image should return to normal.

Q: I’m looking for a composite AV (CVBS) to IP video converter with 4G SIM, 無線上網, and GPS support. I need a P2P video transmitter for a CVBS camera that can create a WiFi hotspot for connection with a Windows tablet. Does it support RTSP streaming? Can I connect using VLC player?
一個: 是. Our CVBS-to-IP video encoder board supports an optional WiFi module that can be configured for P2P server functionality. The device also supports RTSP video streaming, allowing remote video access through a standard network connection. You can connect and view the video stream using VLC Media Player or other compatible RTSP clients on a Windows tablet or PC.

Q: What is the function of the red and black wires next to the video input cable?
一個: The red and black wires are used for DC 5V–12V power input or output. When the encoder board is powered through the DC red/black power wires, the 3Pin wires can also provide power output to an external camera. This allows the encoder board and camera to share a single power source, simplifying the wiring and installation. Red wire: Positive (+) 力量, Black wire: 地面 (接地).

Q: What does the button on the analog video-to-network video streaming encoder board do?
一個: The button is a configuration reset button. If many settings have been changed and you want to restore the original factory configuration, you can press this button to reset the device to its factory default settings. This function is useful for troubleshooting, reconfiguration, or recovering from incorrect parameter settings.

Q: What is the default WiFi password for the CVBS-over-IP encoder board, and what is the RTSP video stream URL?
一個: The default WiFi password is: 88888888. The default RTSP video stream URL is: 即時傳輸協定://192.168.1.188:554/0. You can open the RTSP stream using VLC Media Player or any other compatible RTSP client on your PC, tablet, or mobile device.

Q: Can I remove the timestamp from the video? Can I add custom text or OSD information?
一個:是. The encoder board supports both timestamp display control and custom OSD (螢幕顯示) text settings. You can configure these options from the web configuration page: Web Page Settings → Audio Video Setting → OSD Setting

Q. What is the Wi-Fi password for the CVBS to IP Encoder?
一個: The Wi-Fi connection details depend on whether you are using the encoder in Access Point (美聯社) Mode or Station (史塔) 模式. Please refer to the configurations below:

• 模式 1: Encoder acting as an AP Hotspot (AP Mode) If you are connecting your phone or computer directly to the encoder’s own Wi-Fi signal:

  • SSID (Wi-Fi Name): YRSXA158A2600CA

  • 密碼: 88888888

• 模式 2: Encoder connecting to your local network (STA模式) If you are configuring the encoder to connect to your home or office Wi-Fi router:

  • SSID (Wi-Fi Name): Your local Wi-Fi router’s name.

  • 密碼: The password for your local Wi-Fi router.

Q1. Does this board support both CVBS and AHD input?
是, but not simultaneously. You must power off and restart when switching input formats.

Q2. Can I stream video wirelessly without Ethernet?
是, the Wi-Fi module supports RTSP, ONVIF, and UDP streaming wirelessly.

Q3. What’s the default IP address?
192.168.1.188 — if forgotten, use the IP Search Tool to rediscover the device.

第四季. What is the latency performance?
Latency is typically below 120ms on Ethernet and 150–200ms over Wi-Fi (depends on network conditions).

Q5. Can I connect multiple devices on the same network?
是. Each board can be configured with a unique IP address.

Q6. Is it compatible with NVR or VMS software?
是. 它支持 ONVIF and RTSP, compatible with mainstream NVRs like Hikvision, Dahua, 藍色鳶尾花, and iSpy.

Q9. What is the power consumption?
通常 1.5–2.5W, depending on resolution and Wi-Fi module load.

Q10. Can I view the stream on my phone?
是, via RTSP-capable apps or using the provided Android App R380_1.1.3.

Q11. Does it support motion detection?
是, motion and sound detection are available with optional alert settings.

Q12. Is encryption available?
The stream itself is not encrypted, but protocols like 網路RTC provide built-in secure transmission, and the web UI is password-protected.

Q13. Does it work with 5V battery power?
沒有. 它需要 6–24VDC. 5V or 3.7V power is not supported directly without a boost converter.

Q14. 可以本地錄影嗎?
是, you can record on a TF card up to 256GB or stream to a network NVR.

Q15. Does it support SDK or customization?

  我們的 video encoder board does support 高品質, low-latency IP video transmission over a single Ethernet cable. It can send encoded video streams through standard network protocols, making it suitable for broadcasting, 直播, and multi-camera production environments.

• If you are referring to official NDI® protocol licensing from NewTek:
  眼下, our product does not include official NDI® licensing. If your application specifically requires certified NDI / NDI|HX compatibility, please let us know—we can evaluate potential customization options.

Q18: Which millisecond-precision player or tool do you use to test the latency of the CVBS-to-Ethernet video encoder?
一個: We use OnlyStopwatch to perform millisecond-level latency measurements.
It provides a clear, fast-refreshing timer display that allows us to accurately compare the time shown in the live video stream with the actual system time. This helps us evaluate end-to-end latency and verify the performance of the encoder under different configurations. Download OnlyStopWatch

Q19: I have enabled the motion detection settings, but recording does not start. Can I also receive notifications in the mobile app?

一個: 眼下, the encoder does 不是 support motion detection–triggered recording or alarm functions. Specifically:

• Motion detection–based recording is 無法使用

• Motion detection alarms are 不支援

• Push notifications or alert messages in the mobile phone app are 不支援

These functions have not yet been added to the encoder’s firmware/software. 現在, recording must be started manually or through other supported control methods.
