1 Product Positioning
The VPT300 is designed for conference rooms in enterprises and educational institutions.
Each VPT300 integrates two face detection cameras (a dual-camera system) and 16
microphones (a microphone array) to deliver optimal conferencing experience.
The microphone array detects sound and locates the sound source using a function known as
sound localization. The dual-camera system performs face tracking based on the captured
video images. Generally, the VPT300 supports speaker tracking with accurate localization and
fast focus, enabling a face-to-face communication experience.

2 Product Highlights
The VPT300 provides optimal video layouts with features such as fast localization and
speaker close-up, delivering an immersive conference experience.
Dual-Camera System, Implementing Fast Localization
The dual camera system:
lSupports 84-degree wide angle
lShoots video images for face detection.
lAutomatically detects two participants who are having a conversation and displays their
video images separately in two panes.
lTakes close-up video images of objects within the detection range and calculates their
depth of field (DoF) for fast localization.
lUses a facial recognition algorithm to provide accurate positioning and flexible tracking.
AutoFrame, Providing Optimal Video Layouts
lThe VPT300 automatically adapts to conference scenarios to present best-quality video
images.
lBased on the number, location, and motion of participants, the VPT300 can be
automatically adjusted to provide a dynamic overview of the entire conference room.
Panoramic and Close-up Video Images Displayed in PiP Mode
The panoramic view and close-up video images can be displayed in Picture in Picture (PiP)
mode. That is, the panoramic view is displayed in full-screen mode and the close-up video
images in the small window. This allows you not to miss any details and helps improve
communication efficiency.
SDI Port, Addressing Long-Distance Transmission of Video Images
The SDI port transmits video images taken by the VPT300 to an endpoint that is up to 60 m
away without any distortions. Compared with the analog port, the SDI port does not have any
attenuation when transmitting RGB and YPbPr video signals, providing quality video at lower
costs.

5 Features
5.1 Automatic Tracking
The VPT300 automatically detects and identifies the conference status, takes panoramic and
close-up video images, and tracks speakers. The VPT300 also supports PiP to enhance
interaction experience. Specifically, the VPT300:
lAutomatically detects two participants who are having a conversation and displays their
video images separately in two panes.
lEnters the AutoFrame mode and automatically presents optimal video images when no
participant is speaking.
lTakes close-up video images of the speaker when only one participant is speaking or
multiple participants are speaking in turn.
lTakes close-up video images of several participants when they are speaking at the same
time or in turn.
lTakes a panoramic view when many participants are speaking at the same time or in turn.
5.2 Manual Tracking
After the VPT300 that has two VPC600s installed is connected to an endpoint, you can use
the endpoint's remote control to control the VPC600s. However, only one VPC600 can be
controlled at a time, which can be specified on the endpoint's web interface.
5.3 AutoFrame
The VPT300 automatically adjusts its dual cameras to:
lCapture new participants who come into the conference room.
lDisplay video images of remaining participants at the center of the display after some
participants leave the conference room.
lDetect moving participants and adjust to the optimal angle after detecting no more
movement.

5.4 PiP Display
The PiP mode can be configured for the VPT300 on the web interface of the connected
endpoint and takes effect immediately. However, this mode is available only when the
VPT300 has automatic tracking enabled.
If the PiP mode is enabled, the VPT300 will display panoramic and close-up video images in
PiP mode. When a participant is speaking, the VPT300 displays the panoramic view in full-
screen mode and the close-up video of the speaker in a small window at any of the four
corners. When the participant stops speaking, the small window disappears.
If the PiP mode is disabled, close-up video images will be displayed in full-screen mode.
5.5 Transmission of Infrared Signals
The VPC600 on the VPT300 can transmit infrared signals received from the remote control of
the TE40/TE50/TE60/TX50 endpoint to the VPT300. Subsequently, the VPT300 transmits
signals to the endpoint, and as a result, the endpoint can be controlled by the remote control.
This function is required when the endpoint is placed inside a cabinet and cannot directly
receive infrared signals from the remote control.
5.6 Sleep and Wake-up
You can put the VPT300 and its VPC600 in sleep mode and wake them up from the
connected TE40/TE50/TE60/TX50 endpoint.
lThe VPT300 in sleep mode will wake up if you upgrade the VTP300 or use the VPT300
to upgrade the VPC600.
lThe VPT300 can be put in sleep mode, so can its connected VPC600.
lWhen putting a VPC600 in sleep mode, the VPT300 rotates the VPC600 to the sleep
position and makes it enter the low-power-consumption state.
lWhen you use the remote control of the TE40/TE50/TE60/TX50 endpoint to wake up
the VPC600 in sleep mode, the VPC600 will transmit the infrared signals to the
VPT300. As a result, both VPC600 and VPT300 will have woken up.
lAfter being woken up, the VPC600 will rotate to its initial position.
5.7 Security
The VPT300 provides a variety of security features, such as authentication of debug users,
whitelist, and protocol anti-attack.
System Layer Security
Security maintenance of the system layer ensures a smooth running of the operating system
and supports stable services at the application layer.
The VPT300 uses a customized Android operating system, which delivers enhanced security
and immunity to viruses.

application layer
lWhether services at the application layer can be disabled
lAuthentication modes adopted by the ports
lPort functions (such as data traffic control)
Robustness testing tools are used to scan protocols to ensure that there are no high-risk
vulnerabilities.
Protection of Sensitive Data
To prevent sensitive data from being disclosed, the VPT300 checks the complexity of the
default password and user-defined passwords. A password is displayed as dots (.) or asterisks
(*) when entered in the password input box, and entered passwords cannot be copied.
Sensitive data such as passwords and other encrypted contexts is displayed as asterisks (*) in
logs.
No proprietary encryption algorithms are used.
System Management and Maintenance Security
Software packages (including patch packages) are released after being scanned by at least one
type of mainstream antivirus software with no alarms generated. In special cases, an
explanation is provided for alarms.
Scanning records (including antivirus software name and version, virus library version,
scanning time, and scanning results) are archived and released with the software package
(including patch packages) to customers.
