Costa Rica

The proprietor is a successful business man in Costa Rica. He lives in a high-end community in Palembang. He is meticulous man. We encourage him to install fingerprint sensor and camera cop for his security. After we know he has a 80-year-old mother, we introduce our GSM for him. Thanks to GSM, one time his mother fell down on the floor for more than 5 minutes, and then the infared sensors detected something unusual. The system notified Mr Lin and prevented the tragedy from happening.
