Even with high-frequency functions like 4G wide-area communication and GPS positioning activated, it can support 16 hours of continuous operation, fully meeting the needs of cross-day-and-night duty and long-distance missions. Supports fast charging technology, reaching 80% charge in 2 hours. With a backup battery, it can achieve unlimited battery life, completely solving the power pain point of outdoor operations.<\/div>\n
\n

Multiple Safety Protections, Safeguarding Lives<\/h3>\n<\/div>\n
Designed with a full-dimensional safety guarantee system<\/b> for high-risk scenarios: Equipped with an independently raised SOS emergency alarm button<\/b>, one press triggers a global emergency call, synchronously sending location information, identity credentials, and alarm type. The command center can quickly lock the distressed person’s position and initiate a rescue plan. Supports “Lone Worker Mode”<\/b>\u2014preset safety interval time, and the device automatically sends an alarm reminder if no operation is performed beyond the set time, providing active protection for personnel on solo missions. Features “Man Down” function<\/b>\u2014real-time monitoring of user status via a built-in posture sensor. When a severe fall or prolonged lying down is detected, it automatically triggers a high-decibel alarm and sends a rescue signal to the command center, protecting personnel safety from multiple dimensions. In addition, it supports bidirectional switching between emergency alarm and silent alarm, allowing public warning or concealed distress call based on on-site conditions to flexibly respond to different dangerous scenarios.<\/div>\n
\n

Rich Communication Functions, Adapting to Full-Scenario Dispatching Needs<\/h3>\n<\/div>\n
Integrates diversified communication modes<\/b> to meet full-scenario needs from daily communication to emergency command: Supports one-on-one private calls (Individual Call), multi-person group intercom (Group Call), and global broadcast calls (All Call), enabling flexible switching according to mission scale. Features Call Alert function with synchronous audio-visual prompts to avoid missing important instructions. Supports Short Message transmission for sending text commands, location coordinates, status reports, etc., enabling efficient communication in scenarios where voice communication is inconvenient. Built-in multiple Alert Tones, allowing customization of prompt sounds for emergency, regular, and notification types to quickly distinguish command priorities.<\/div>\n
\n

Remote Intelligent Management, Greatly Improving Operation Efficiency<\/h3>\n<\/div>\n
Equipped with OTAP (Over-the-Air Programming)<\/b> technology, enabling remote wireless configuration and system upgrades via telecom operator networks\u2014no on-site device connection required. Administrators can batch modify parameters such as communication frequency, group information, and function permissions in the background, and support remote push updates of firmware versions, significantly reducing operation and maintenance costs and improving device management efficiency. Particularly suitable for large-scale deployment scenarios, it avoids the cumbersome process of debugging devices one by one, achieving efficient operation and maintenance “without leaving the house”.<\/div>\n
\n

HD Voice Experience, Clear Communication in Noisy Environments<\/h3>\n<\/div>\n
Adopts AI intelligent noise cancellation technology<\/b>\u2014via a built-in high-performance microphone and digital signal processing chip, it real-time filters environmental noise (such as mechanical roar, wind and rain, crowd noise, etc.), accurately extracting human voices, improving voice clarity by over 40%. Paired with a 2W high-power speaker<\/b>, the maximum volume reaches 110 decibels with strong penetration, ensuring clear hearing of voice commands even in noisy environments within 10 meters. Supports voice enhancement algorithms that automatically optimize human voice frequency bands, making communication smoother during long-distance intercom and in high-noise environments, completely solving the pain point of “unclear hearing” with traditional walkie-talkies.<\/div>\n
\n

\u00a0All-Round Connection Expansion, Unlocking More Practical Scenarios<\/h3>\n<\/div>\n
