FAQ

Q: Is it possible to have a digital zoom function in this encoder?
A: No, our CVBS to Ethernet IP encoder does not support a digital zoom function. This device is designed to convert analog CVBS video signals into Ethernet (RTSP) streams. It does not process or modify the video content itself.

Digital zoom is typically a function of the camera or the video management software (VMS), not the encoder. Therefore, 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 (UART) commands available for IoT?
A: Our encoder board supports UART (serial port) data transmission, but it works in a transparent pass-through mode.This means the encoder does not define or generate specific UART commands itself. Instead, 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.

For example, 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?
A: 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, WiFi, 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?
A: Yes. 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?
A: 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 (+) power, Black wire: Ground (GND).

Q: What does the button on the analog video-to-network video streaming encoder board do?
A: 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?
A: The default WiFi password is: 88888888. The default RTSP video stream URL is: rtsp://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?
A:Yes. The encoder board supports both timestamp display control and custom OSD (On-Screen Display) text settings. You can configure these options from the web configuration page: Web Page Settings → Audio Video Setting → OSD Setting

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

Q2. Can I stream video wirelessly without Ethernet?
Yes, 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.

Q4. 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?
Yes. Each board can be configured with a unique IP address.

Q6. Is it compatible with NVR or VMS software?
Yes. It supports ONVIF and RTSP, compatible with mainstream NVRs like Hikvision, Dahua, Blue Iris, and iSpy.

The stream itself is not encrypted, but protocols like WebRTC provide built-in secure transmission, and the web UI is password-protected.

Q13. Does it work with 5V battery power?
No. It requires 6–24VDC. 5V or 3.7V power is not supported directly without a boost converter.

Q14. Can I record video locally?
Yes, you can record on a TF card up to 256GB or stream to a network NVR.

Q15. Does it support SDK or customization?
Yes, SDK is available for developers for player-side secondary development.

AP vs STA Wi-Fi Mode on CVBS to IP Encoder Module

Q17: Does your video encoder board support the NDI protocol?
A: Thank you for your question. Could you please clarify what you mean by NDI protocol?

• If you are referring to the functionality:
  Our video encoder board does support high-quality, 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, live streaming, and multi-camera production environments.

• If you are referring to official NDI® protocol licensing from NewTek:
  At the moment, 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?
A: 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?

A: At the moment, the encoder does not support motion detection–triggered recording or alarm functions. Specifically:

• Motion detection–based recording is not available

• Motion detection alarms are not supported

• Push notifications or alert messages in the mobile phone app are not supported

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

Q20: Are the FTP settings shown in the system currently active?

A: No. The FTP configuration page is for reference only and is not active at the moment.

Q21: Will FTP upload work if I fill in the FTP server information?

A: No. In the current firmware version: FTP upload is not enabled. Snapshot or file upload via FTP will not take effect. The FTP settings page is reserved for future functionality.

Q22: Can I connect a USB flash drive in parallel?
A: Yes, the device supports recording to a USB flash drive (U-disk).

Q23: What is the pinout of the 4-contact connector?
A: The 4-pin connector has a 2.0 mm pitch. From top to bottom, the pins are:

1. GND

2. D+

3. D-

4. VCCIN / 12 VDC

Q24: Does this board support a battery to save settings when the power is turned off?
A: Yes. All settings on the board are saved automatically when power is lost. You can also use a 2–3 cell lithium battery to maintain the saved settings during power interruptions.

Q25: Will the USB interface support direct connection of a 4G module?

A: The board does support 4G modules, but only when using our compatible 4G module. Direct connection with other 4G modules is not supported.
