OVERVIEW
Overview
The GPS Shoulder Light Tracker is designed for organizations that need both personnel visibility and location management. Unlike an ordinary flashing shoulder lamp, this product integrates satellite positioning, cellular communication, Bluetooth and an LED matrix display into a small wearable device.
The tracker supports GPS and BeiDou for outdoor positioning, while WiFi and LBS provide supplementary location references in areas where satellite signals are weak. Its outdoor positioning accuracy can reach less than 10 meters under suitable conditions. With 4G Cat.1 communication, location and operating data can be transmitted to a remote monitoring platform.
Supervisors can use the PC platform or mobile application to view the latest personnel location, check device status, review historical routes and manage electronic geofences. The reporting interval can be configured to balance tracking frequency, data usage and battery operating time.
The LED matrix display improves visibility during night patrols, traffic control, road maintenance and emergency operations. Its compact 68 × 30 × 20.5 mm housing can be attached to a uniform, reflective vest or shoulder strap without interfering with normal work.
This wearable GPS shoulder tracker is suitable for security companies, traffic management departments, construction contractors, railway operators, factories, municipal service teams and emergency response organizations. It can help replace manual attendance records, improve field personnel dispatching and provide traceable movement data.
Shenzhen Jinshengchang Technology Co., Ltd. provides OEM and ODM development for GPS Shoulder Light Tracker projects. Available services include customized branding, housing development, LED display content, firmware functions, server protocols, API integration and white-label GPS tracking platforms.
