Case Study: Coin Parking Challenges At Company C, a coin parking operator, the traditional handset intercom was being handled clumsily by users, leading to frequent malfunctions. Additionally, the handset system required users to get out of their cars to use it, and due to the need for installation inside a box to protect against rain and wind, users had to open the door to operate it, which was particularly problematic during rainy weather as users would get wet. The intrusion of rainwater and deterioration of equipment due to outdoor installation were also serious issues, resulting in skyrocketing maintenance costs. Implementation Effects With the hands-free calling feature of the CIT-200, users can now make inquiries and calls while remaining in their cars, allowing for comfortable use even in rainy weather without getting wet. The automatic answering function ensures that when calls come in from the call center, the system automatically switches to hands-free mode, enabling communication with users and allowing them to make calls without confusion. The IP65 waterproof standard has completely eliminated malfunctions caused by rainwater intrusion, and the stainless steel housing maintains stable performance even with long-term outdoor use. The integration with the payment machine through I/O functionality allows for automatic reporting of equipment anomalies, and simple issues can be resolved by users themselves through voice guidance, contributing to a reduction in the burden on the call center.

Case Study: Demand Bus Call System Challenges In urban G City, the awareness of the demand bus service was low, and improving convenience had become urgent. The traditional reservation system was not facilitating use by the elderly or inbound tourists, and phone reservations took time to specify locations, making real-time responses difficult. Improving access in densely populated areas, around existing bus stops, and near subway stations was also a challenge. Implementation Effects By installing the CIT-200 in densely populated areas within the demand bus operation range, at some bus stops, and near subway stations, users were able to contact the demand bus dispatch center with a single touch whenever needed. Orders from the intercom allowed for location specification, making real-time responses easier at the call center and enabling quick instructions to the optimal vehicle. The IP65 waterproof standard ensured stable operation even when installed outdoors, establishing a system available 24 hours a day.

Issues At the cable car of tourist spot F Mountain, it has been a long-standing challenge to secure a means of emergency communication within the vehicles due to the difficulty of laying wired telephone lines in the mountainous area. Additionally, the rapidly changing weather conditions made the durability of the equipment an important requirement. While communication via radio was considered, there were issues with the complexity of operation and voice quality. Implementation Effects By installing the CIT-200 in each cable car vehicle, passengers can now report emergencies directly to the operation management center. With 4G/LTE compatibility, stable communication is ensured even in mountainous areas. The stainless steel casing and IP65 waterproof rating provide sufficient durability to withstand vehicle vibrations and changes in weather conditions. Hands-free dialing allows for easy operation during emergencies. Voice guidance provides instructions on how to use the system, alleviating passengers' anxiety. Remote management enables the operation management center to continuously monitor the communication equipment status of all vehicles.
