According to NICB, more than 1 million cars were stolen in the US alone in 2022, reaching such a number for the first time since 2008. Regular vehicle trackers help to solve this concern, but they are harder to hide because they need to be connected to a power source – vehicle battery. Experienced thieves expect to find a GPS tracker and will try to locate it destroy it. SOLUTION： To solve this social challenge , RichLink designed GL103, It's very easy to hide anywhere in the car, there is no need to connect any wires, and it provides accurate GNSS location tracking. GNSS Satellite Cellular Network InternetServer Tracking Platform Mobile APP Location Tracking Movement Based Tracking Small and Easy to Install IP68 RatingAnti Tamper GL103 Use Case 2 - Keep your Perishable Goods Secure CHALLENGE： Perishable foods, vaccines and pharmaceuticals, chemicals and electronics are typically sensitive to exposure of temperature variations as well as shock, tilt, vibrations and light.These types of goods require a steady and controlled temperature environment throughout the entire supply chain.If there is no independent sensor to monitor the ambient system, when a malfunction occurs, the consequences is significant. SOLUTION： RichLink created GL103, a versatile solution. It integrates with temperature sensor, motion sensor, light sensors, and even barometer sensor, allowing for continuous monitoring of the entire environment surrounding your goods at all times Cellular Network InternetServer Tracking Platform Mobile APP GNSS Satellite <2024 Gosuncn.
