How to find the NVD-25 on an IP net work

By default, once the physi cal connections have been made, the NVD­25 will try to obtain an IP Add ress from a DHCP network server.

As we will see this can be changed later to a Static IP address if
required.

How to use the NVD-25 IP Finder utility
software

Datavideo supplies a free, Windows based utility, called NVD-25 IP
Finder. The first time this software is used on the computer you may

need to grant permission through your computers firewall / anti-virus
software in order for it to be able to scan or search the local network.

When the utility scans the LAN that the computer is connected to, it
displays the current IP address for any NVD-25 units found on this
local IP network. Double clicking on the device listed will automaticall y
open your computer ’s default web browser and navigate t o the l ogin
page of the NVD-25.

If you are using an Apple computer then you can use an alternative
utility app such as Fing or Network Analyzer Lite.

NVD-25 Login using a web browser

Type the numbers of the IP address for the NVD-25 into the search
bar of the browser. Remember to include the dots in between the
numbers. When entered you will then be asked to login to the NVD-25.

Alternatively you can simply double click the IP address listed in the
NVD-25 IP finder.

Default Login det a i ls

All NVD-25 units are delivered from the factory wi th the same default
user name and password. Thi s can be changed at a later stage to suit
your needs.

User = admin
Password = 000000 [Zero six times]

Please Note: We recommend the Mozilla Firefox web browser

NVD-25 web browser Home page

Once we have logged into the NVD-25 we are presented with the Home page.

Settings opt i on

When clicked, the Settings option tab will open a new page. There are five
sections of settings which can be looked at. These are:

• Audio Setup

• Display Setup

• Network Setup

• Live Stream Setup

• Account Setup

Network Video Decoder

Settings > Audio Setup

By default the NVD-25 will output audio over the digital SDI connection and
the analogue stereo connections. Alternatively you can choose to output
digital or analogue audio only. Available audio decoders are Software

(MP3+AAC) and Hardware (AAC).

Settings > Display Setup

By default the NVD-25 will output video over the digi tal SDI port at a
resolution of 720P 50 fps.

Please note: The set resolution is only applied when the stream is
decoding, the device wi ll output your monitor’s preferred resolution as
it boots.

Outp ut To

Here you can select to output video di gitally over SDI or over the SD
analogue composite connection.

SDI (Digital)

When digital is selected you can select a screen resolution from SD
PAL/NTSC right up to HD 1080P60. The NVD-25 will scale your
source video to match the output resolution however the aspect ratio
(4:3 or 16:9) should be matched to avoid black space on the output.
For optimal performance, match the output resolution to the source
video.

Composite (Analogue)

When analogue is selected, the UI will change and you can only select
between PAL and NTSC resolution with a 4:3 or 16:9 aspect ratio.

Settings > Network Setup

By default the NVD-25 will obtain its IP address automatically from a
DHCP server.

If you intend to connect the NVD-25 directly to a PC or network
without a DCHP server then you should assign a manually set IP
address by selecting ‘Static Configuration’.

We recommend that only advanced users who are aware of IP
addressing set the manual ‘Static Configuration’ IP address. Your local
network administrator or I.T. support may be able to help you with this.

Settings > Live Stream Setup

From this page you can configure the source stream for the decoder.
The NVD-25 supports the following stream types:

• RTSP over UDP (Unicast / Multicast)

• RTS P over TCP

• RTSP over HTTP

• MPEG-TS over UDP

• RTM P over TCP

• UDP r aw (Unicast/Multicast)

• HLS over HTTP

Buffer Size

This determines how much video is buffered before playback starts,
the default 0.5 seconds is fine for streaming over Ethernet but a larger
buffer may be required to achieve smooth video when streaming over
the internet or WiFi.

RTSP protocol

Only valid if the RTSP stream is being used, the transport protocol can
be manually specified.

MISC. Options

Enable Safe Buffering (TCP Only) must be checked if the stream type being
used is HLS over HTTP.

Settings > Account Setup

The NVD-25 has one admin user account and password. This account
is used to keep the NVD-25 secure and gi ves access to the streaming
settings.

Default user name = admin Default password = 000000 [Zero six times]

This section describes how you can change the defaul t username and

password shown above to something new which is more secure.

1. Log in the NVD-25 server as normal using the computer web
browser.

2. Click Setting

3. Click Account Setup

4. Click admin and then enter the new user name and password.

5. Click ‘Save Changes’

Please Note: Please be careful and memorize the new login details
as the old or default login is deleted during this process.

Decoding vi deo f r om t he NVS-25 encoder

The decoded video from the NVS-25 and to the NVD-25 must be on
the same local network (Ethernet/W iFi) or be able to access the NVS­25 stream over the internet.

When the NVS-25 is in RTSP TCP/UDP mode (Recommended for
LAN)

Simply copy the RTSP URL from the ‘Live’ tab of the NVS-25 and
enter it into the ‘Input Stream’ field on the NVD-25. When streaming
over LAN it is recommended to set the NVS-25 in RTSP (T CP/UDP)

mode.

When the NVS-25 is in RTMP mode Local server mode

Simply copy the RTSP URL from the ‘Live’ tab of the NVS-25 and
enter it into the ‘Input Stream’ field on the NVD-25

When the NVS-25 is in HLS mode

The NVS-25 does not currently publish its full HLS stream URL. To
decode its local HLS stream please copy the URL bel ow replacing the
IP address with that of your NVS-25 unit and enter it into the ‘Input
Stream’ field on the NVD-25.

http://admin:000000@192.168.16.69/hls/live.m3u8

If on the NVS-25 you have changed the password from the default of
000000 please al so replace the si x zeros in the URL above with your
new password

Please Note: W hen in HLS mode the buffer size should be set to 0.7
seconds or higher.

Decoding other stream types

To decode other stream types such as UDP multicast, simply enter the
stream URL into the ‘Input Stream’ field of the NVD-25.

Listening for a Pushed UDP Stream

To listen for a pushed UDP stream, enter the following URL into the
‘Input Stream’ field of the NVD-25.

UDP://@:9710
Replace 9710 with the port number of the pushed stream.

Automatic Firmware Updates

The NVD-25 features an automatic update system to avoi d the need
for the user to have to manually install firmware upgrades.

The NVD-25 will automatically check for updates whenever it is
connected to the internet.

You will be notified if an update is available when the unit is next
started. A firmware update question will appear for 10 seconds on the
selected video output (SDI or Composite), to update simply click on
the Yes button and then follow the prompts.

Please note: A USB mouse must be connected to install updates.

Port Forwarding on your firewall / router

So that an NVS-25 video stream can be seen on the internet (beyond
the default gateway) certain network related ‘ports’ should be opened
on your router or firewall. Your local network administrator or I.T.
support should be able to help you with this.

Enable the “port forwarding” function or open below ports within the
router settings.

NVD-25. If you have questions, please refer to related sections and
follow all the suggested solutions. If problem still exists, please contact
your distributor or the service center.

No.

Problems

Solutions

1.

Do I need to enable safe

buffering for HLS playback?

HLS playback should work

without safe buffering enabled
however if the buffer is set
below 1.0 it will stutter.

Safe buffering is recommended
for HLS due to the way the

protocol works.
