The BF-TD937 digital two-way radio features an industrial rugged design. Its robust form not only enhances durability but also delivers a crisp visual aesthetic. Whether navigating dense urban clusters for unimpeded communication or operating in open spaces or weak signal environments, it consistently delivers clear, robust audio output. Its rich feature set effortlessly handles diverse complex scenarios, while advanced communication technologies provide users with a stable, efficient communication experience, comprehensively boosting communication efficiency.

Industrial Rugged Design

Single Frequency Repeater (SFR)

The BF-TD937 digital two-way radio combines industrial aesthetic design in both exterior and structure. Utilizing the superheterodyne circuit structure, it not only showcases a rugged professional feel but also guarantees stable performance and powerful communication signals in complex environments. Equipped with a 1.77-inch full-color display, it provides clear visibility of information, offering the best humanized interactive experience. Its unique acoustic chamber design achieves powerful, transparent voice transmission, ensuring clear command delivery even in noisy environments or at signal coverage edges.

BF-TD937 has stronger signal penetration, equipped with a high-power signal transmission, ensuring wider coverage and better transmission and reception effects. Meanwhile, it supports Single Frequency Repeater (SFR), effectively boosting communication range and expanding coverage in scenarios requiring long-distance signal transmission such as mountainous areas, industrial parks, and large venues. This not only widens the communication range but also helps users efficiently conserve valuable frequency resources. It ensures clear and stable communication among team members even over long distances, guaranteeing timely command transmission and facilitating prompt, smooth task execution.

Multiple Alarms

Advanced Voice Encryptions

BF-TD937 establishes a comprehensive operational safety protection system. In emergencies, personnel can manually trigger a one-touch emergency alarm, instantly sending precise location data and distress signals to teams or the command center. Meanwhile, when personnel unexpectedly fall, the BF-TD937 automatically issues a man-down alarm, enabling passive protection. Additionally, opt for the lone worker mode. If no device operation or movement is detected within a preset timeframe, the system automatically identifies an emergency and sends an alert, providing invisible safety monitoring for independent workers. This three-tiered protection mechanism ensures rescue signals can be promptly transmitted during emergencies, whether through active assistance requests or passive triggers, significantly enhancing personnel safety in complex environments.

BF-TD937 supports advanced encryptions, empowered by AES256/ARC4 algorithms, delivers high-strength encryption for communication content, effectively fending off eavesdropping, cracking and signal interception risks. Ideal for scenarios demanding stringent information confidentiality, such as public safety, emergency rescues, security patrols and government & enterprise operations, it significantly enhances communication security and privacy, ensuring maximum protection for voice communication.

Precise Multi-Mode Positioning (Optional)

Digital Voice Recording (Optional)

Supports GPS/GLONASS/Galileo and the BDS positioning for fast and accurate acquisition of real-time location information. Not only can the BF-TD937 autonomously record and display coordinates, but it also enables one-touch sending or sharing of positioning information with team members. It supports integration with dispatch command systems for automatic location reporting, enabling precise visual management in operational coordination, safety monitoring, and emergency response. This ensures teams always maintain critical situational awareness of location dynamics.

BF-TD937 provides 24/6 hour recording versions to meet different scenario requirements. The 24-hour mode supports round-the-clock monitoring, preserving all voice conversations. The 6-hour mode focuses on temporary tasks or key periods, storing critical content. BF-TD937 is equipped with the stealth mode that instantly disables all lights and sounds, completely concealing the device's operational status. Ideal for high-sensitivity, high stealth missions like law enforcement evidence collection and security reconnaissance. It ensures traceable voice records while preventing walkie-talkie exposure.

IP68 Protection

Multiple Version Options

BF-TD937 is built to strict U.S. MIL-STD and achieves the IP68 protection, delivering triple-proof durability against dust, water, and drops. It withstands harsh outdoor challenges like sandstorms, rain, and falls while reliably handling high-intensity industrial environments. This makes it your teams dependable communication backbone for seamless, efficient collaboration even in the most challenging conditions.

BF-TD937 supports different versions and modes, including PDT/DMR Conventional, PDT/DMR Trunking, Ad-Hoc, BelFone Smart Digital IP Connect System (SDC) and BelFone Smart Virtual Trunking System (SVT). Users can select the most suitable terminal configuration based on actual operational scenarios, management models, and functional priorities. This guarantees precise and efficient communication support for routine operations, emergency command, and intelligent dispatch applications.
