1. Product Overview
1.1 System Introduction
Th BG-MAESTRO combines 4K ultra-definition imaging, video analysis technology and
electronic PTZ control technology to enable a single camera to output close-up main stream,
close-up sub-stream, panoramic main stream, panoramic sub-stream and blackboard stream
simultaneously. This camera can track and detect accurately and quickly, and fully meet the
requirements of various scenes of teaching recording and remote interactive teaching.
1.2 Main Features
Intelligent lecturer tracking: Built-in image recognition and tracking algorithm allows the
camera to track targets quickly and accurately without the need for auxiliary positioning
cameras or a tracking host.
Strong anti-interference ability: Once the tracking target is locked, it is resistant to
acquisition of interfering subjects.
●Smooth tracking: The sensitivity of action can be adjusted and it will not be affected by
target’s minor movement or gestures.
●Strong environmental adaptability: The tracking performance is not affected by
classroom’s size, shape or seats layout.
●Intelligent director: Built-in intelligent director switching strategy;
●Multiple tracking modes: Support multiple tracking modes, including tracking mode, movie
mode and area tracking mode.
●Ultra HD: 1/2.8 inch high quality 4K CMOS sensor; support 1080P@30fps/25fps image
output.
●Wide view angle and distortion-free lens: Using ultra wide-angle, distortion-free camera;
supports 3X digital zoom and EPTZ control at the same time;
●Low noise and high SNR: Low Noise CMOS effectively ensure high SNR of camera video.
Advanced 2D/3D noise reduction technology is used to further reduce the noise, while
ensuring image sharpness.
●Multiple video compression: H.265, H.264, MJPEG;
●Multiple video outputs: Supports SDI, USB3.0 and LAN (Gigabit);
●Multiple streams: Supports five streams, simultaneously outputs close-up main stream,
close-up sub-stream, panoramic stream, panoramic sub-stream and blackboard writing
stream;
●POE support: A single network cable can support power, control, and video output
simultaneously, thus simplifying wiring installation.
●Multiple installation: Wall mount and in-ceiling mount for options.
●Networking control interface: Controlling via Network can meet different deployment of
various scenarios.
●Wide application: Lecturer capture, remote interactive teaching etc.

4.1 Installation Layout
Teacher tracking camera is installed at 1.6 –2.1m (5 –7 feet) from ground(distance from panoramic
lens to ground), and the distance from the blackboard is 5 -9 m (15 –30 ft). Teacher tracking camera
should be installed as close to the center of the classroom as possible to achieve the best result.
(Supports ceiling mounting)

4.2 System Wiring
The teaching tracking camera products provide a smart camera solution for education
environments, and customers can select all or some products as needed. Different combinations of
products meet the demands of customers’ in various scenarios.
5. Network Connection
5.1 Connection Mode
Direct connection: Connect the camera directly to the computer by using an ethernet cable.
Internet connection mode: Connect the camera and computer to a router or switch and access via
the local area network (LAN).
Note: Ensure power and network connections are secured to prevent video issues caused by poor
connection quality.
The computer must be on the same subnet as the camera to connect successfully. The device will
not be accessible otherwise. The camera default IP address is 192.168.5.163, therefore the computer
must be connected to the 192.168.5.x subnet.

9
To connect to the camera, open the Local Area Connection Properties on the computer.
For Windows users right-click on the internet connection in the lower right corner of the desktop.
Select “Open Network & Internet Settings.”
Select “Change Adapter Options.”
Right-click on your connection (Wi-Fi or Ethernet) and select “Properties.”
Select “Internet protocol version 4 (TCP/IPv4)” as shown below and click “Properties.”
For the following steps refer to the diagram below.
Click on the bubble for “Use the following IP address.”
In the IP address field enter a non-conflicting IP address on the same subnet as the camera. If there
is another device with the same IP address you will not be able to connect. In the example below
we are using 192.168.5.200
In the Subnet mask field enter 255.255.255.0
In the Default gateway field type 192.168.5.1
You can leave the DNS fields blank.
Click OK to apply your settings.
Note: When you are finished configuring the camera you will need to return to this screen and click
the bubbles for “Obtain an IP address automatically” and “Obtain DNS server automatically”
to restore internet connectivity to your computer. Also make sure to reconnect any ethernet cables

teacher tracking configuration is shown in Figure 5.6-1
Figure 5.6-1 Operation interface
1. Click stop tracking
2. Preset setting of the platform
The operation interface for setting the preset position is shown in Fig. 5.6-2. By controlling the
position and ZOOM value of the PTZ, the camera Angle and position are adjusted to the preset
position and saved. The description of the preset position of the podium is as follows.

Figure 5.6-2 Operation interface
Platform preset: Control teacher tracking camera to capture the platform (we suggest that teachers
stand in the middle of platform during setup) in camera image, then click and save platform preset.
During normal tracking, the size of the teacher’s image in the picture uses Platform preset as a
reference. When the tracking target disappears, the close-up lens will return to the platform preset.
3. Panoramic preset setting
The operation interface for setting the preset position is shown in Fig. 5.6-3. By controlling the
position and ZOOM value of the PTZ, the camera Angle and position are adjusted to the preset
position and saved. The panoramic preset settings are described below.
Figure 5.6-3 Operation interface
