Notices
• This MSolutions product contains electrical components that may be damaged by electrical spikes, surges, electric
shock, lightning strikes, etc. Use of surge protection is highly recommended in order to protect and extend the life
of your equipment.
• The transmission distances of data over Cat cables are measured using TE CONNECTIVITY 1427071-6 EIA/
TIA-568-B termination (T568B) of cables is recommended for optimal performance. To minimise interference of
unshielded twisted pairs in the CAT5e/6 cable, do not run the Cat5e/6/6a cabling with or in close parallel proximity
to mains power cables.
• Do not substitute or use any other power supply other than the enclosed unit, or an MSolutions approved
replacement. Do not disassemble either the Transmitter or Receiver units for any reason. Doing so will void the

Introduction
The 4k Conference Camera from MSolutions delivers the best technical equipment available to ensure
smooth and productive video meetings. The MS-4K71-12TR tracking camera consists of two video cameras
with identical sensors: Pan-Tilt-Zoom (PTZ) for moving objects and Panorama cameras for a static object.
For example, lecturer and audience, classroom - the fixed Panorama camera targets the blackboard and the
PTZ camera tracks the lecturer.
The MS-4K71-12TR Conference Camera streams high quality image at 4K (3840x2160), allows a 71 degree
field of view, and 12x optical zoom. Even under poor light conditions, the camera will adjust automatically to
stream vivid video quality thanks to its automatic low-light correction technology. Furthermore, the camera
is designed with image recognition and tracking technology to achieve a smooth and natural tracking eect.
This camera captures both panorama and close-up HD video at the same time, a very convenient feature for
every occasion.
The built-in microphone is highly sensitive and equally picks up sounds from all directions. MS-4K71-12TR’s
noise reduction algorithm blocks out background noises, ensuring crystal clear conversations during video
meetings.
Key Features
• All-in-One Design - Integrated design, can output panoramic and close-up multi-channel HD
video at the same time.
• Intelligent Tracking- Built-in image recognition and tracking algorithms, without any prior
auxiliary camera positioning or tracking of the host, achieves a smooth and natural tracking
eect.
• Adjustable Viewing Angle - The viewing angle of the panoramic camera can adjust vertically
(15° ~ 0°), making it convenient for installation and configuration.
• 71 ° wide-angle lens + 12x optical zoom - Exclusive custom high-quality true 8 million ultra-high-
resolution 4K ultra-wide-angle lens with 12x optical zoom and horizontal field of view up to 71 °.
• H.265 encoding - H.265-encoded ultra-high-definition tracking camera, which can realize ultra-
high-definition 4K ultra-low-bandwidth transmission.
• Multiple interfaces - Supporting HDMI2.0 high-definition output, and it is also equipped with
a 3G-SDI interface. The eective transmission distance is up to 150 meters (1080p30). HDMI,
3G-SDI, USB3.0, LAN can output 4 HD digital signals at the same time.
• Built-in G-sensor - Support automatic image flip function, convenient for engineering
installation.
• 4K UHD - Using a 1 / 2.5 inch high-quality UHD CMOS sensor with a maximum size of 8.51
million pixels, it can achieve 4K (3840x2160) high-resolution high-quality images. Backwards
compatible with multiple resolutions such as 1080p, 720p.
• Built-in microphone - Built-in microphone array, omnidirectional pickup, pickup distance up to 6
meters, unique noise suppression algorithm, perfect speech presentation.

be taken.
4) Bit Rate
The user can specify the bit rate. Generally speaking, the larger of the bit
rate, the clearer of the image. However, the configuration of the bit rate
needs to be combined with the network bandwidth. When the network
bandwidth is narrow and the bit rate is configured larger, the video stream
cannot be transmitted normally, and the visual eect is worse.
