1. System overview
1.1 System introduction
The ALF-XX-HD-TC / ALF-XX-SD-TC is a dedicated smart camera solution leading in the international
education information industry.
The tracking camera features a built-in high-speed processor and advanced image processing and
analytical algorithm, which allows it to track and detect teachers, students and blackboard-writing
accurately and quickly. It fully satisfies all scenario demands by recorded broadcasting of teaching
and remote interactive teaching.
The tracking camera adopts an advanced ISP processing technique and algorithm, producing vivid
images which feature balanced brightness, distinct layering, high definition and colour reducibility.
The ALF-XX-HD-TC range are characterized by improved function, high performance, reliable
operation, simple use and easy maintenance.
1.2 Product advantages
Full-scene solution: Different product combinations satisfy different scenario demands.
Networked control interface: Control information of all products will be transmitted via a
network, and it is suitable for product layout for all scenarios.
Recognition algorithm unrelated to the location: Status detection and recognition of
teachers and students adopt a unique smart partitioning algorithm to ensure that the result
of detection and recognition is unrelated to location.
Ease of installation: Supports both standing installation and upside-down installation.
All-in-one design: The built-in panoramic lens allows the perfect combination of panoramic
lens and tracking camera.
Sophisticated tracking algorithm: It applies sophisticated human detection, locking and
tracking image processing and analytical algorithm (smart image recognition library, scene
adaptive algorithm), and achieves stable, fast and accurate target tracking.
High immunity from interference: More diversified and flexible recognition shield settings
ensure that once the tracking target is locked, it will not be affected by another moving object
or projector.
Stable tracking: Movement sensitivity is adjustable. When tracking a slight movement of
target or hand movement, it will not cause the wrong operation of the camera.

Self-adaptive image: The tracking camera zooms depending on the distance to target so that
the visual image maintains proper size and scale.
High environmental suitability: Tracking result will not be affected by classroom size, shape
or seat arrangement.
Super wide dynamic exposure: Solves the issue that tracking object dims in strong light such
as a projector.
1.3 Product features
Full HD image: With a 1/2.8-inch-high quality image sensor, the maximum resolution ratio is
1920x1080.
Multiple optical zoom lens: 12X and 20X optical zoom lens are available. The lens features a
72.5° distortionless wide viewing angle.
Advanced focusing technique: The advanced automatic focusing algorithm allows automatic
focusing to be done quickly, accurately and steadily.
Low noise high signal to noise ratio: Low noise CMOS ensures super high signal to noise ratio
of video taken by the camera. With advanced 2D and 3D noise reduction technology, noise is
reduced, and image resolution is guaranteed.
Audio input port: It supports 16000, 32000, 44100, 48000 Hz sampling frequency and AAC,
MP3 and G.711A audio coding.
Super quiet mechanism: High precision stepping motor and precision motor-driven controller
ensure the PTZ mechanism operates at low and stable speed without noise.
Multiple video compression standards: It supports H.265 / H.264 video compression.
Multiple networking protocols: It supports ONVIF, GB/T28181, RTSP, protocol and RTMP
push mode.
Sleep mode: It supports low-power consumption sleep / wake up mode. Power consumption
in sleep mode is lower than 400mW.
Multiple control protocol: Supports VISCA, PELCO-D, PELCO-P protocol, automatic
recognition protocol and all command VISCA control protocol.

The tracking camera is installed about 1.8 - 2.5m from the ground (distance from the panoramic
lens to the floor), 5 - 15m from the blackboard (when the distance is 5 - 9m, 4mm panoramic lens
is recommended; when distance is 9 - 15m, 6mm panoramic lens is recommended). Teacher
tracking camera should be installed near the central axis of the classroom as much as possible to
get the best result of tracking camera shooting.
4.2 System wiring
The tracking camera provides a smart camera solution for the education information field.
Different combinations of products meet the demand of customers’ application scenarios.
If the recording and broadcasting host supports the LAN network control port, the network hub
can be replaced by a LAN network switch.

5. Configuration tools
5.1 Set IP address of the tracking machine
Open Alfatron tracking software, click Settings -> IP address -> Search successively (refer to Figure
5.1-1 for details), the configuration interface will display all valid devices in the LAN, check the type
of device to be configured and click Confirm. Note: The computer for operating the Alfatron
tracking software tool should be in the same LAN with the camera to be configured.

1. Set the preset position for close up
The operation interface for setting preset position for close up is shown in Figure 5.2-2.
The framed area indicated by the arrow has the PTZ control buttons. By controlling the Pan / Tilt
position and Zoom value, it will adjust the camera angle and position to the desired preset position.
Settings of panoramic preset position and platform preset position are as follows:
Figure 5.2-2 Operation interface
Platform preset: Control the tracking camera (close up camera) to create a platform area and get
the desired visual result in-camera image, then click and save Platform preset. During normal
tracking, the size of the persons image in the picture uses a Platform preset as a reference. When
the tracking target disappears, it can select a close-up lens to go back to the Platform preset.
Panoramic preset: Control tracking camera to allow it to have a panoramic view of the classroom
(or any position). When the tracking target disappears, it can select the close-up lens to go back to
the panoramic position.
2. Set panoramic lens area
Platform area: This is the area that is tracked once the close-up lens starts tracking. There is a
blackboard within the platform area generally to ensure that when the teacher is on the platform
their upper body is displayed within the set area, and it will not exceed the lower margin of the
platform area when students in the first row sit down. See Figure 5.2-3.

Figure 5.2-3 Operation interface
Tracking area: Tracking area means the scope of area tracking the teacher. When the tracking
target goes out of the tracking area, it will be considered as tracking target lost. The tracking area
can be set into a polygon shape according to certain environmental conditions or set student area
outside of tracking area. See Figure 5.2-4:

16
Mask area: The mask area is an area that may impact the effectiveness of target tracking, these
are places that may have dynamic changes such as monitors, projector, doors, and windows. See
Figure 5.2-5:
Figure 5.2-5 Operation interface
3. Set tracking parameters
Target lost:When the target is lost, the close-up lens will return to a designated preset position.
This preset position can be the Panoramic Preset, Platform Preset or Maintain Original Position.

Tracking settings:
Auto-zoom: In open mode (checked), during tracking, the camera will zoom automatically
according to target distance; in off mode (unchecked), during tracking, zoom remains to the value
set during platform preset.
V-move: In open mode (checked) and during tracking, the camera will adjust its angle of elevation
according to the height of the tracking target; in off mode (unchecked) and during tracking, the
angle of elevation remains to the value set during platform preset. If a teacher does not step down
from the platform in class, we suggest turning off the auto-zoom and v-move.
Figure 5.2-7 Operation interface
Advanced parameters:
Action sensitivity: In tracking mode, it is the action range required to trigger the tracking camera
when the tracking target changes from a stationary state to a motion state. The higher the action
sensitivity, the smaller the movement of the tracking target that will trigger the camera’s tracking
motion.
H-speed: It means the speed of the camera for horizontal tracking.
V-speed: It means the speed of the camera for vertical tracking.
Zoom range: The bigger the range, the higher zoom extent required for the camera when the
tracking target steps down from the platform.
Lost timeout: This means the time required (5s by default) for the camera to perform the target
lost action when the target is lost (options: return to panorama preset, platform preset, or remain
original position).
