Feature Introduction

Core Competitive Advantage: A lightweight, two-in-one device combining a warning shoulder light and positioning functionality; a lightweight wearable device for field duty.

Traditional field personnel need to wear a shoulder light and a locator separately. This product integrates the two into one, with a shoulder clip design that is weightless. The red and blue flashing lights enhance the safety of the duty personnel, while also transmitting personnel location in real time, supporting voice notifications, and one-button emergency alarms. It is lightweight and suitable for urban management, sanitation, and patrol personnel.

● Dual-mode intelligent power saving: The location is reported every 15 seconds when a person is moving around; the location is reported after 3 minutes of rest without vibration, balancing real-time performance and battery life.

● Trajectory optimization and inflection point compensation: The device detects changes in steering angle and automatically uploads the location, avoiding trajectory breaks during turns, resulting in more realistic route restoration in the background.

● The platform uses TTS (Text-to-Speech) to convert text to speech, and notifications can be played directly through the device's speaker, eliminating the need for field staff to hold their phones.

● SOS Emergency Mode: Press and hold to trigger alternating red and blue flashing lights, continuously uploading location every 15 seconds and simultaneously pushing SOS alerts to the background.

● Multi-channel fusion positioning: precise outdoor positioning with BeiDou/GPS, indoor WiFi + base station coverage, no signal loss in buildings and streets.

Application Scenarios

Police patrols, urban management field operations, sanitation and cleaning, emergency rescue, road administration inspections, and park security personnel location alerts.
