The NVS-30 is a small and portable video streaming encoder and recorder. This device is designed specifically for simultaneous encoded video streaming and high quality video recording. The NVS-30 accepts any HDMI input source (such as camera or switcher) and streams the input video directly for broadcast to YouTube, Facebook, and other live streaming platforms.

The NVS-30 generates an RTSP or RTMP compliant H.264 encoded video stream. While streaming, you can record the video in MP4 or MOV file format on an SD card, USB thumb drive, or a network drive simultaneously. You can also use a web browser on the PC or mobile phones to control the device from a remote location.

Unbalanced analog stereo output via 1/8” (3.5mm) jack – pass
through of input.
Line Level
H.264/MPEG-4 Part 10 (AVC) Video Encoder
Resolutions Selectable encoding resolutions ranging from:
128x128 to 1920x1080
Bit Rates Ranges Record Only Mode: 100 kbps to 30 Mbps
Stream Only Mode: 100 kbps to 20 Mbps
Independent Stream and Record Mode**:
Recording: 100 kbps - 30 Mbps
Streaming: 100 kbps - 10 Mbps
Maximum combined total bitrate of 30 Mbps
**Note that when both streaming and recording resolutions are
above 1280x720, the encode parameters must be identical for
both processes. Completely Independent recording and
streaming settings are available when either the streaming or the
recording resolution is 1280x720 or below.
Encode Frame Rates Encode frame rates representing 1:1, 1⁄2 and 1⁄4 of the input
frames rates are supported
Note that the maximum encode frame rate is 30 fps when encode
resolution is 1920 x 1080
Encoding Profiles Baseline, Main and High
Encoding Controls 2.0, 3.0, 3.1, 4.0, 4.1 Level Support
GOP Size and Structure
Variable bit rate support
Average max/min data rate controls Deblocking Filter
MPEG-4 AAC Audio Encoder
Standard AAC-LC
Sample Frequency 32, 44.1 and 48 kHz when digitized from analog source
Channels 2 channels Stereo (L/R)
Bit Rates Range from 32 kbps to 256 kbps
High Quality multi-tap 10 bit Down Scaler and De-Interlacer.
Available to both streaming and recording operations.
Recording File Format
File Type Industry Standard MP4 and MOV files with two channels of
embedded AAC audio.
Recording Lengths Maximum file length of 300 minutes - irrespective of storage type
used. File splitting feature allows a user to record continuously for
long periods by defining file segment sizes. The NVS-30 will
create these sequential file segments over the course of the
recording operation without losing a single frame of video.
File segment can have a length of 1 to 300 minutes.
Network Interfaces
Connector RJ45 providing 10/100/1000 Base-T Ethernet
with Static or DHCP addressing
Protocols RTMP, RTSP/RTP
IPv4 Support
Unicast and Multi Unicast
(number of clients may vary from 3 to 10)
User Interface
Physical Interface Independent streaming and recording Start/Stop control
Storage Types for File Recording
2x USB 2.0 Support for NTFS (3.1) and FAT32 file system
The NVS-30 will support writing to USB3 devices at USB2
speeds. Also note, there is a very high variability in the
performance capabilities of “thumb” drives (even USB3 versions).
Many are optimized for “read” operations while the NVS-30
requires sustained “write” capabilities. For best results, NVS-30
recommends using powered USB drives. If small portable media
is required, SD cards may be more suitable.
1x SD card Slot Supports SD and SDHC cards. Only NTFS formatted SDXC
cards are supported. (Class 10 highly recommended).
Network Mapped Drive Support for writing to shared folders in computers found on a
network using Windows Share protocols
(suitable for windows system) as well as NFS protocols
(suitable for Mac and Linux systems).
