NVS-30 FAQ

Configuring the Encoder 

Configuration is done via a web browser. The address is the local IP address of the encoder, assigned by your network's DHCP server.

The easiest way to get the IP address is to power on the NVS-30 with the HDMI output connected to a monitor. It will display the IP during the boot sequence. More details are in the product manual.

The NVS-30 software, available via the product page, is only for updating the firmware, it is not a configuration tool.

Please note that while some versions of the manual mention a MacOS version, it is Windows only.

If you experience any graphical or functional issues in the web browser interface, please update your browser, re-open it, and try again, or switch to a different browser.

Could Not Open Resource for Writing Error 

When you start to stream and get the error message "could not open resource for writing", your network and the streaming service may require a secure connection. YouTube and Facebook Live have options for SSL.

Once enabled, the RTMP URL will change from rtmp:// to rtmps://. Paste this new URL into the NVS-30 stream setup and apply. It should now complete the connection and begin streaming

Default Static IP 

When supplying power to a NVS-30 for the first time, the device powers up in DHCP IP mode for connecting to a network with a DHCP server, such as through a router.

If connecting NVS-30 to a network without a DHCP server, you must set the device to Static IP mode by pressing the Record button on the device during its power-up sequence when the Record LED flashes.

The default Static IP address is 169.254.1.11

If the LED does not flash, press the Reset button located on the rear panel of the device to initiate a device reboot. During the power-up sequence (all LEDs illuminate), the Record LED should flash for three seconds.

Lost IP

If you lose you IP settings and do not want to perform a factory reset, connect a FAT or NTFS formatted thumb drive to the NVS-30's USB port 2.

The current IP address and status of the NVS-30 will save to the drive as a text file, which can then be viewed on a computer.

Simultaneous Stream and Record

​In Stream-and-record operating mode, if the current stream encoding resolution exceeds a width of 1280 and/or height of 720, and you want to record at a resolution greater than 1280×720, the stream and record settings must use the same encoding settings.

In this case, you must select the Use stream settings for recording option.
