  • Page 13: Video Streaming

    In this section, we will show you how to set up and start your video streams. Streaming Network Connection and Device Search Let’s first detail how to connect the NVS-35 to a network with or without a DHCP server, and acquire the NVS-35’s IP address.

  • Page 14: Connecting To A Non-Dhcp Network (Static Ip)

    Fixed IP is primarily used in point-to-point connection, such as directly connecting the PC to the NVS-35. In a non-DHCP environment, the NVS-35 only works in fixed IP mode. To set the NVS-35 to a fixed IP or the default IP, please follow the steps outlined below: Connect the NVS-35’s LAN port to the network via an Ethernet cable.

  • Page 15: Troubleshooting The Network Connection

    Troubleshooting the Network Connection Connect the NVS-35 to the network and open the IP Finder utility program. Scan for the device. If not found, it is possible that your network is not assigning IP addresses. Reasons of this are outlined as follows: Router or DHCP server is not responding to the device’s request.

  • Page 16: Web User Interface

    Web User Interface By now, we have obtained the IP address of the NVS-35. To open the web user interface, either double click the device’s IP on the IP finder or enter the device’s IP into the address bar of a web browser then hit the ENTER button. Log in by entering the username as well as the password into the pop-up dialogue box as shown below.
  • Page 17 If you’ve selected HDMI, you will be allowed to adjust the source video’s brightness, contrast, hue and saturation by dragging the corresponding sliders as shown in the diagram below.

  • Page 21 Stream Type The NVS-35 offers the user four stream types which are RTSP, RTMP, TS, HLS and SRT. Parameters of each individual protocol will be briefly described below. RTSP (Real Time Streaming Protocol)  RTSP Port: The RTSP port number ranges from 554 to 562 and is 555 by default.
  • Page 22 Kuaishou This is designed specifically for a streaming platform in China. Please note that when streaming, the NVS-35 converts video into data, which are sent across an IP network. High bitrates consume more bandwidth across the IP network. In a gigabit office LAN, high bitrate may not be a concern and Speed/Bandwidth is therefore not a limitation in an NVS-35 application environment.
  • Page 23 Available video bitrates are listed as follows:        512K  256K Audio Bitrate (bps) The NVS-35 offers the user the following audio bitrates at which you may want to stream the audio. It is recommended to select 128Kbps or higher.
  • Page 24  384K  256K  128K   Encoder Mode The Encoder Mode sets the video bitrate mode for your video stream. The available modes are listed as follows:  High (8M)  Medium (4M)  Low (2M) Tip: You can also switch between different bitrate modes by pressing the Bitrate button on the front panel.
  • Page 25   Record Mode The NVS-35’s record engine allows you to record your program on the SD card. See Section 5 for a list of recommended SD cards. The record parameters shown in the diagram below will be discussed in detail in this section.
  • Page 26 Note that after you’ve configured the record settings, click “Apply” to apply the new record settings. Click “Start Record” to start recording and “Stop Record” to end recording. To reset, simply click the default button. File Name Enter the name of your record file. Resolution Recording resolution is the number of pixels (dots) used to create an image.
