The HW03 GPS Enabled 4G Smart Watch is a student-centric wearable designed to prioritize safety while enhancing campus connectivity. Equipped with 4G network support and IP68 waterproof rating, this lightweight (≈36g) device combines durability with smart technology—ideal for primary and secondary school students. It serves as a dual-purpose tool: enabling convenient campus access for students and providing schools with a centralized system to collect student data (e.g., attendance, location). Key selling points include real-time location tracking, emergency SOS calling, and class-friendly undisturbed mode, making it a trusted companion for parents seeking peace of mind and schools aiming to strengthen safety protocols.

The HW03 uses a fusion of positioning technologies—Beidou, GPS, Glonass, A-GPS, Wi-Fi, cellular signals, and AI algorithms—to ensure high accuracy both indoors and outdoors. It also stores up to 7 days of historical location trails, allowing parents and schools to review student movement patterns. The built-in electronic fence feature alerts administrators or parents if a student steps outside predefined safe zones (e.g., school campus, residential area).
• SOS Emergency Call: One-click SOS triggers the watch to send alert texts and call preset emergency contacts. If the call is unanswered or hung up, it automatically redials twice.
• Family Call Management: Parents can set whitelisted family contacts, enabling students to make/receive calls only from authorized numbers—blocking spam or unknown calls.
The “Do Not Disturb” schedule function locks the watch screen and disables calls/messages during class hours, ensuring students stay focused on learning without interruptions.
Schools can use the dedicated management platform to uniformly configure settings: set family contacts, adjust electronic fence boundaries, and schedule non-disturb periods. Parents also benefit from customizable APP support to monitor their child’s location and call history.
• Primary & Secondary Schools: Deployed as part of campus safety systems to track student whereabouts, manage attendance, and facilitate quick communication between students and parents.
• After-School Activities: Waterproof design (IP68) makes it suitable for outdoor events, sports classes, or rainy weather without damage.
A1: Thanks to multi-technology fusion (GPS/Beidou/Wi-Fi), the watch achieves positioning accuracy of 1-5 meters outdoors and 5-10 meters indoors—sufficient for tracking students within campus or residential areas.
A2: IP68 protects against dust and short-term immersion (up to 1.5 meters for 30 minutes), making it safe for daily use (e.g., handwashing, rain). However, it is not recommended for swimming or prolonged water exposure.
A3: Battery life depends on usage: typically 1-2 days with regular use (calls, positioning checks) and up to 3 days in low-power mode (minimal calls, periodic positioning).
A4: Yes, the customizable parent APP allows setting real-time location update intervals (e.g., every 15/30 minutes) and electronic fence alerts—parents receive notifications immediately if their child leaves a safe zone.
Parents can designate family contacts, enabling students to call family members. Multiple whitelisted numbers may also be configured, blocking all non-authorized incoming calls.
Schools can use the platform to centrally manage Student GPS Tracker, uniformly set up family numbers, establish electronic fences, and configure non-disturb time periods, thereby improving the school's administrative efficiency.
