Chapter 5 Video Streaming
The NVS-33 Video Streaming Server allows user to stream and record your program
at the same time. From any SDI/HDMI input sources, the Datavideo’s video
streaming server generates an H.264 encoded stream that is compliant with RTSP or
RTMP, RTMPS protocols. While encoding the video at bit rates appropriate for live
streaming, the Datavideo NVS-33 concurrently records a high-quality MP4 file to an
SD card.
5.1 Streaming Network Connection and Device Search
This section details how to connect the NVS-33 to a network with or without a DHCP
server, and describes how to acquire the NVS-33’s IP address.
Connecting to a DHCP Network (DHCP Mode)
Follow the following procedure to scan your DHCP network for connected NVS-33
devices.
Note: The NVS-33 will be automatically assigned an IP address upon connection to
the DHCP network.
1. Connect the NVS-33’s LAN port to the network via an Ethernet cable.
2. Turn on the power of the NVS-33, the default mode of the NVS-33 is
DHCP mode.
3. Connect the laptop to the same network that the NVS-33 is connected to and
download the free IP Finder utility program from the product page
https://www.datavideo.com/tw/product/NVS-33.
4. Double click the IP Finder utility program icon to open the IP
Finder interface.
5. Click the SCAN button to start searching for connected devices.

18
Connecting to a NON-DHCP Network (Static IP)
Upon connection to a non-DHCP network, the NVS-33 will not be assigned of any IP
addresses. As such it is recommended that you manually assign a fixed IP address to
the device or use the default IP address (192.168.1.60).
Default Fixed IP
Default Fixed IP is primarily used in point-to-point connection, such as connecting
the PC to the NVS-33 directly. In a non-DHCP environment, the NVS-33 works in fixed
IP mode only. To configure the NVS-33 to the default IP, please follow the steps
outlined below:
1. Connect the NVS-33’s LAN port to the network via an Ethernet cable.
2. Turn on the NVS-33’s power and the NVS-33 will also be turned ON in
the DHCP mode by default.
3. Search for the NVS-33device according to the method as detailed in the previous
DHCP section. Once found, log into the user interface on the web browser.
4. Enter the system page by clicking the “System” tab on the home of the user
interface.

19
5. In the “Network Setting”, disable the DHCP mode.
6. You will then be allowed to manually enter the static IP address once the DHCP
mode is disabled. The static IP is 192.168.1.60 by default. The subnet mask and
default gateway are 255.255.255.0 and 192.168.1.254 respectively.
Tip: If you forget or lose the IP address, do the following to reset the network
settings.
Turn off the NVS-33.
Press the RECORD and STREAM buttons at the same time then turn ON the
power of the NVS-33.
Wait for about five seconds and release the button push as soon as you see
the RECORD and STREAM button LEDs light up.
The IP address should be the default IP which is 192.168.1.60.
Troubleshooting the Network Connection
Connect the NVS-33 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 connected to the network.
New devices are blocked by the network administrator.
Anti-virus software or the firewall blocks the communication.
Solve the problem by attempting the following:
Turn off the router, wait for 10 seconds then turn on the router again.
Reset the NVS-33 to the factory default:
-Turn off the NVS-33.
-Push the RECORD and STREAM buttons simultaneously while turning
on the NVS-33’s power.
-Wait for about five seconds and release the button push as soon as you
see the RECORD and STREAM button LEDs light up.
Reboot the PC.
If the problem still persists, try the following ways:

20
Temporarily shut down the anti-virus software or firewall.
Make sure no other devices are connected to the LAN (wired or wireless)
because this may result in IP conflicts.
After trying all methods and if the problem is still not solved, the NVS-33 video
streaming server offers the fixed IP feature that allows you to establish direct
connection to the NVS-33. The default IP address is 192.168.1.60.
This method allows you to configure the NVS device to the IP range of your network
so that you do not need a DHCP server to gain access to the NVS device.
Connect your PC to the NVS device directly using an Ethernet cable (not
necessarily a crossover cable).
Next, change the network settings of your Windows7 or Windows 10 PC or laptop.
Click START located at the bottom left corner of your screen.
On the text bar, enter Network Connections then click the icon that
appears.
Double click the network adapter that connects your PC or laptop to the
network.
Click the “Properties”button.
Select “Internet Protocol Version 4 (TCP/IPv4)”option and click the
“Properties”button.
Check the “Obtain an IP address automatically”option.
Enter IPv4 settings:
-IP Address: 192.168.1.2
-Subnet Mask: 255.255.255.0 (System default is 255.255.255.0)
-Default Gateway: Not required for one-to-one connection.
