When operations demand speed, clarity, and reliability, a standard body camera is not enough. S1 is designed to support real-time monitoring, better incident documentation, and more efficient command response.
With 5G transmission, and a three-camera design, S1 gives teams more visibility and more control in the field. It helps improve situational awareness, streamline evidence capture, and support operational decision-making when every second matters.
If your team needs a professional-grade wearable camera for modern public safety work, S1 delivers the advanced features that matter most.
S1 supports 5G, 4G, and Wi-Fi transmission for low-latency live video. This allows command teams to monitor field conditions faster and respond more effectively to evolving situations.
The camera supports 4K recording for high-definition evidence capture. Clearer video helps improve incident review, documentation, and post-event traceability.
S1 includes AI recognition features that support smarter field use and improved operational efficiency. This makes the device more than a simple recorder.
The main and auxiliary cameras provide broader coverage and better visibility in the field. This is useful for capturing different angles during patrols, inspections, and enforcement activities.
The 3.1-inch touch screen makes the device easier to use in daily operations. It supports quick interaction and convenient control in the field.
Integrated GPS and BeiDou positioning help track personnel location in real time. This improves supervision, route playback, and dispatch coordination.
S1 supports audio and video communication, allowing teams to exchange information directly between the field and the command center.
In an emergency, the SOS function allows users to send an immediate alert. This helps supervisors react faster and improves field safety.
Infrared recording supports low-light and nighttime use. It helps maintain reliable video capture when visibility is limited.
S1 also supports starlight night vision, delivering clearer image quality in low-light environments and improving visibility for nighttime operations.
NFC adds another layer of operational flexibility and user interaction. It can support identity-related or workflow-related functions depending on deployment needs.
S1 is built for extended use in demanding work environments. Its power design supports long field sessions and practical daily deployment.
S1 supports H.265 video compression, which helps reduce file size while maintaining efficient video quality. This improves storage efficiency and makes video transmission more practical for connected field use.
S1 is well suited for organizations that need a connected body worn camera with advanced performance and strong field value.
It is ideal for:
Police patrol.
Traffic enforcement.
Public safety operations.
Urban management.
Emergency response.
Transport inspection.
On-site command and dispatch.
For each of these scenarios, S1 helps teams capture events clearly, coordinate faster, and maintain a stronger record of what happened in the field.
S1 is designed to improve both field performance and management efficiency. It is built for teams that need more than a camera.
5G transmission enables faster live video access, helping command teams understand events as they unfold.
4K recording, three cameras, and audio-video recording support better documentation and stronger incident review.
GPS, SOS, and two-way communication help teams respond quickly when situations change.
AI recognition and positioning functions support more intelligent supervision and better operational control.
The touch screen, NFC support, and wearable design make the device practical for daily use in the field.
Grandtime develops connected wearable devices for public safety and industrial operations. S1 reflects that focus by combining high-speed transmission, advanced recording, and field communication into one professional device.
If your team needs a body worn camera for modern dispatch, evidence capture, and real-time supervision, Grandtime can support both standard supply and project-based customization.
