Feature Introduction
Core Competitive Advantage: Integrated head-mounted video system + multi-dimensional construction site safety sensors, enabling comprehensive monitoring of personnel video, location, and work behavior.
Unlike separate locators, this product directly integrates with a national standard safety helmet. Wearing the helmet simultaneously completes video recording, personnel positioning, and multiple risk detections such as helmet removal, electric shock, and falls. The backend can view the on-site footage, personnel location, and violations in real time, providing one-stop digital management of construction site personnel.
● High-definition video evidence collection: 109° wide-angle 4MP lens, 1080P segmented loop recording, automatic GPS time watermark overlay on video, dual TF cards for expansion up to 128G, clear and effective incident tracing.
● Automatic alarms for six major safety risks: removing hats, falling, high voltage proximity warning, high-risk electronic fence, prolonged stationary stay, and one-button SOS distress call.
● Cluster voice system: remote two-way intercom, full-staff text broadcast (TTS) broadcast, and unified dispatch of front-line construction personnel by the management center.
● Multiple positioning options are available: standard GPS/BeiDou; optional RTK differential outdoor centimeter positioning and UWB indoor high-precision positioning, with no blind spots in tunnels and factories.
● Outdoor work aids: 3W long-range high-intensity flashlight, laser positioning light, and night/underground construction lighting markers.
● Convenient battery life: 4000mAh removable polymer battery, allowing for 8 hours of uninterrupted construction throughout the day, and 2A fast charging for quick recharging.
