4. Installation and Connection
4.1 Video signal connection
Connect HDMI signal from a source (such as camera) to the device HDMI port
through a cable.
4.2 Network connection
Connect the network cable to Ethernet port, and connect the other end to the
network switch or directly to the network port of the computer.

7
4.3 Power Connection
Using the power adapter (DC 12v) to connect to the power connector of the
device. Turn on power switch, the power light will be on and the device starts
working, which will take 30~40s.
Note: If your switch supports POE power supply, there is no need to
connect to the power supply.

5. Login and Network Configuration
5.1 Device login
1. The default management IP address for the device:
The default management IP address of the encoder is 192.168.1.16, which could
be used as device management all the time and no effects on the device business
IP address. Net mask is 255.255.255.0.
2. Computer network configuration
Click “network and Internet setting” -- “Network and sharing centers”—
“Ethernet”—“Internet agreement version 4”—Use below IP address, enter
192.168.1.* manually (* refers to the number from 1 to 255 besides 168 ) and net
mask, click “Login”.
3. WEB management page login
Open the WEB browser, enter 192.168.1.168 in the URL. Fill the username and
password in the login interface. Both default username and password are admin.
Note: Due to the browser compatibility issues, it may cause the webpage
display abnormal, it is recommended to use Chrome and Firefox.
5.2 Network configuration
5.2.1 Ethernet
After login, you could configure internet IP by DHCP or manually (Default is

9
DHCP). This IP address could be used for network streaming and device
management. After configured IP address, you could directly visit this IP address
to login to the device.
There are two ways to get the address, one is DHCP, and the other is manually. To
use DHCP, please ensure that the router or switch has enabled the DHCP service.
This method is simple and convenient, but the IP obtained by DHCP changes
continuously, and you cannot directly know what IP address the encoder gets. To
select manually, you need to enter a fixed IP to the device, and this IP address is
fixed as long as the device does not restore the factory settings, this method is more
stable. Therefore, the two methods have their own advantages, and can be selected
accordingly.

10
5.2.2 Advanced setting
HTTP/HTTPS setting
The default web service port is 80 (https port is 443). You can change it (range: 1-
65535) accordingly. After revised corresponded port, visit device configuration
page. You need to add the changed port behind the device IP address before you
visit. For example, the device normal login IP address is 192.168.1.168, change
Web service port from 80 to 90, HTTPS service port from 443 to 450, then enter
192.168.1.168:90 or https://192.168.1.168:450 to visit device respectively.
By HTTPS, if the web browser prompts certificate errors which is caused by the
browser certificate security authentication, you will need to add it to the safe list of
the browser.
Routing strategy
The routing strategy is for routing release and reception. Its operation object is data
package. According to the needs, the data packet transmission path can be changed
according to a certain strategy. When the device is connected to multiple network
links, the different data link can be sent according to the appointed network link
through designated strategy, which improves the utilization efficiency of the link.

11
Note: It is required that professional person with knowledge of the
current network routing table or network to operate routing strategy. Incorrect
configuration may cause device abnormal.
6. Parameter Configuration
6.1 Status column
In the status column, the left window is for preview of the video source either with
image or video. When preview with image, you will see image stream, which refresh
every 3 seconds. When preview with video, you will see smooth video. You can
control and switch image stream and video stream through the switch button. If the
preview window is displayed in black, it means the video source has not been
detected by the device, and you need to check whether the input cable is plugged
in correctly. The icon and in the lower left corner of the preview window
can realize the functions of safety frame and center line for the preview video.
The parameters for main stream and sub stream are showed at the right window.
You can switch the pages through clicking main stream and sub stream in the upper
left corner. Brief introduction of the relevant encoding parameters as below:

12
⚫Video source: Display the interface of the source
⚫Encoding format: Display the encoding format of the source
⚫Resolution: Display encoding resolution of the source
⚫Real time bit-rate: Display real-time encoding bit-rate changes of signal
source.
⚫Network flow: Display the real-time consumption flow changes of signal.
⚫Audio source：Display audio format of the signal source
⚫Memory usage: Status of content usage
⚫Storage space: The usage status of internal storage space
⚫CPU：The usage status of CPU
6.2 Audio and video encoding setting
Click setting button in the status column, enter to “audio and video encoding
setting” interface.
6.2.1 Audio and video signal source setting
There is only one HDMI input for the device, video source defaults to HDMI. For

13
audio source, you can select HDMI embedded audio or analog Line in. Default
setting is HDMI embedded audio.
6.2.2 Video encoding parameter
Main streaming encoding parameters setting parameter as below:
⚫Two ways of encoding mode, the main stream and sub stream can be
selected as H264 or H265.
⚫“Scaling” has 7 options for choice. Default setting is “Default size”, that
is, the video size after encoding is the same as the input video size. You can also set
to encode low resolution input into high resolution output, and similarity, high
resolution input can be encoded into low resolution output.
⚫“Color” has two options: “With color” and “monochrome”.

14
Monochrome is black and white color, “with color” remains the original color.
Default setting is “With color”.
⚫“Profile” supports High profile, main profile, baseline, which is set
according to platform supported encoding profile. High Profile is the highest
compression efficiency, that is, under the same bit-rate, image quality is the best;
Baseline is the most widely supported; default setting is High Profile, which should
be based on the actual platform supported (Only one profile for H.265 encoding).
⚫“Bit-rate control” has two ways: CBR (Constant bit-rate) and VBR (Variable Bit-
rate). From literal meaning, CBR is stable and unchanged bit-rate, while VBR is
constantly changing according to actual content. Generally, network
transmission adopts CBR to guarantee transmission quality, while file storage
uses VBR to guarantee file quality. Default setting is CBR-Constant bit-rate.
⚫“Bit-rate” supports adjustable 20K-40M. You can select as we set or self-
define bit rate. Theoretically, the higher bit-rates, video quality after encoding
is better. But specific setting should be based on actual network situation, and
couldn’t be higher than your own upstream bandwidth.
⚫“Framerate” support adjustable from 1FPS to 60FPS and customized
framerate, customized framerate is user assigning framerate manually after
encoding, in theory, it shouldn’t be higher than original framerate.
⚫“GOP size” has seven options and supports user-defined adjustment. GOP
（Group of Pictures）is a group of consecutive picture, the strategy of GOP
affects encoding quality. It is adjustable according to actual situation, default is

15
60, and normally it could meet the most majority of needs.
6.2.3 Audio encoding parameter
Audio encoding modes include AAC and G.711 for choice. Audio sampling is
chosen according to actual situation. Audio channels consist of “Stereo” and
“Mono”. Encoding bit-rate is adjustable between16K-512K, default is 64Kbps.
The input channel supports 4 audio channels input. You can select two channels
for encoding output and add, delete, modify audio channels according to your
needs. Each pair audio channel can be set as different encoding mode, sampling
and mapping relationship between input channel.
1）You had better to create 4 audio channels, click “+”and new audio channel
created.
2）Set audio name, encoding mode, sampling and mapping relationship between
input channels.
