    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-34 to a network with or without a DHCP server, and acquire the NVS-34’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-34. In a non-DHCP environment, the NVS-34 only works in fixed IP mode. To set the NVS-34 to a fixed IP or the default IP, please follow the steps outlined below: Connect the NVS-34’s LAN port to the network via an Ethernet cable.

  • Page 15: Troubleshooting The Network Connection

    Troubleshooting the Network Connection Connect the NVS-34 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-34. 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.

    Record which will be discussed in detail in this section. Stream Mode The NVS-34 has two stream engines allowing you to stream to two different destinations over multiple protocols such as RTSP, RTMP, TS and HLS. See Section for instructions on each individual stream setup.
  • Page 20 Note that once your video streams are set up, click “Apply” button to apply the new stream settings. Click “Start Stream” to open the stream and “Stop Stream” to end the stream. To reset, simply click the default button. Next, we will discuss the stream setting options in greater detail. Encoder Source This option allows you to enable the stream encoder for configurations of various parameters.
  • Page 21 Stream Type The NVS-34 offers the user four stream types which are RTSP, RTMP, TS, and HLS. 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 554 by default.
  • Page 22 Resolution The first step of encoder setup is to adjust the image size. It is best to either match your original video source or scale it down. For example, capture at HD 720 and stream at HD 720, or capture at HD 720 and stream at 540 (high). You should never be scaling up and streaming at a higher resolution than your original video source.
  • Page 23 available upload bandwidth capacity on a DEDICATED line. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed available, your combined audio and video bitrate should not exceed 1Mbps. Usually high bitrate means good image quality; however, there are also exceptions. For example, SD video may appear acceptable at 1000 Kbps (1M) but HD video is unacceptable at 1000 Kbps.
  • Page 24 Level Levels specify the size of the video a decoder must be able to handle. They specify a maximum bit-rate for the video and a maximum number of macroblocks per second. Level numbers range from 1 to 5 with intermediate steps (e.g., 1.1, 1.2, 1.3 and etc). The table below provides a summary of maximum parameters supported by each H.264/AVC level.

  • Page 27 File Name Enter the name of your record file. Resolution Recording resolution is the number of pixels (dots) used to create an image. Higher resolutions use more pixels to create an image. This means that greater amounts of detail can be expressed in the image, but larger files sizes and a greater amount of storage (i.e.
  • Page 28  30fps – Videos with a lot of motion, such as sports, will often benefit from the extra frames per second.  60+fps – Anything higher than 30fps is mainly used to create slow motion video or to record video game footage. Video Bitrate (bps) The bitrate of the video specifies the amount of information stored in the video.
