Belfone’s new generation of professional DMR radio BP620. With its advanced AI noise reduction, sensitive receiving and transmitting, accurate positioning, and effective response speed, greatly improves users’ communication experience in noisy environments, to provide users with a more sensitive, clearer, and more reliable communication guarantee.
Highlights
-
AI Noise Reduction
BP620 equipped with a high-performance speaker and AI Reduction, can effectively filter background noise and eliminate whistling. It can also accurately extract the human voice to ensure that the radio sound can still be accurately captured in all kinds of noisy areas achieving a clear and loud call.
-
Multiple Encryptions
BP620 adopts multiple encryptions to guarantee all-round secure communication, supporting ordinary encryption (dynamic encryption, static encryption), and AES256, ARC4, effectively improves the privacy of communication and the security of information.
-
IP68 Protection
BP620 has IP68 certification. It is made of PC protective material, which can still maintain intact in rain, soaking, dust, etc. The screen has been reinforced with excellent impact resistance, can withstand 1.5 meters fall at multiple angles, easy to work in any harsh environment.
-
Rich Applications
BP620 supports an optional Bluetooth 5.0 modular that allows to access wireless audio device, wireless PTT device, offering extensible accessory options. Besides that, it also allows an optional 250 hours recording to sustain long time communication.
-
Satellite Positioning
BP620 supports displaying the location and distance of the target during the call. It can equipped with satellite positioning for real-time tracking and managing static and moving status, effectively coordinating and managing personnel, and improving command and dispatching efficiency.
*Customizable:GPS、GALILEO 、GLONASS
-
Multiple Alarms
BP620 supports multiple alarm modes including one-key alarm, lone worker, and man down. Once an emergency occurs, it can automatically notify the commanding officer or the dispatching command platform to ensure the safety of personnel in different scenarios and effectively eliminate potential safety hazards.
-
Strong Communication Performance
The TDMA two-time-slot function of terminals allows users to achieve better voice capacity and audio performance in a wider range of signal environments. It also enhances the system management of digital communication. It can be coordinated with the Belfone SDC and SVT systems for command and dispatch, intelligent management, and channel allocation services.
-
RF Optimization
The motherboard of BP620 adopts an integrated metal shield to effectively isolate the interference and improve voice communication quality. Thanks to its new circuit optimization scheme, it provides a wider and more sensitive transmitting and receiving signal, ensures the transmitting and receiving of key voice in signal fringe areas, and realizes stable communication in complex environments such as high floors, large areas, and long distances.
