We have started providing the virtual signage display system "VirtuSign."

For tunnel construction and night work! Displaying highly visible virtual signs to contribute to safety management.

The Virtual Sign is a system that projects pre-set signs from a high-brightness light source mounted on the main device, by setting the signs in advance on the cloud at the site office or similar locations. By brightly and clearly projecting signs at tunnel construction sites or nighttime construction sites, it effectively informs site workers of restrictions and raises awareness. Various sign contents for use at construction sites are prepared, and the display content can be changed remotely via the cloud, reducing the hassle of installing or replacing signs and leading to labor savings. The main device is equipped with a communication terminal, and the connection to the cloud can be selected from LTE, wired LAN, or Wi-Fi. It is also possible to project sensor information and surveillance camera footage installed at the communication site via the cloud. Additionally, it has dustproof performance that allows it to be used without impact in tunnel construction, as well as waterproof performance for use in rainy weather. By projecting images from a high-brightness light source, it is possible to create large and clear sign displays, similar to projection mapping, by installing the device in locations that do not obstruct vehicle traffic.

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.

The Natural Disaster Prevention System ZEROSAI has been utilized by many general contractors since its launch. Since the start of operations, it has been implemented at over 1,000 civil engineering and construction sites and is currently being widely used as a weather countermeasure on construction sites. As a successor service to the Natural Disaster Prevention System ZEROSAI, we will release the Comprehensive Weather Platform ZEROSAI X-AI on February 18, 2026. ZEROSAI X-AI can centrally manage weather forecasts for construction sites, weather and environmental data, and hazard notifications. It allows all personnel on site to visualize various dangers such as sudden heavy rain, strong winds, heatstroke measures during summer, linear precipitation zones, and typhoons. While leveraging the strengths of traditional centralized management, we have newly added an AI-based wind speed forecasting feature. Additionally, various functions such as chatbots have been added or improved, making it even more convenient. For service details and catalogs, please visit our website.

Hotron's "HA Series" is a high-performance doorway monitoring sensor. Even for high doors of 4.0m, it ensures safety while proposing an open and inviting entrance with its doorway monitoring function. 【Surface-Mounted Type HA-400】 ○ Safe and comfortable passage is achievable even with high doors, from lightweight doors to large commercial facilities and office buildings. ○ Maximum installation height of 4.0m! It features a high-density area function with 60 detection spots. 【Recessed Type HA-520】 ○ With a flat finish that does not compromise the aesthetics of the building, it ensures a wide area for safe and comfortable passage. ○ Easy replacement from older models of our own, enhancing sensor performance! 【Lower Surface-Mounted Type HA-430】 ○ With a design that minimizes protrusion and presence, it enables safe and comfortable passage even with high doors. ○ Detailed detection areas can be set while maintaining high density according to the site conditions. 【Ceiling-Mounted Type HA-260】 ○ An industry-first pull-down method provides a flat finish for ceiling-mounted sensors that do not compromise the aesthetics of the building. ○ The detection area achieves a wide coverage with high density of 72 detection spots! ◎ For more details, please contact us or download the catalog.

The "SLK85" is an extendable outdoor unit cover that can be easily attached with magnets, protecting the outdoor unit from heat. By creating a space between the cover and the outdoor unit, it improves ventilation, making it less likely for heat to accumulate and enhancing heat insulation effects. It has been tested at a wind speed of 27 m/s. It features a tool-free design, making it easy for anyone to use. Please feel free to contact us if you need assistance.

Grabee's forest fire AI detection system detects flames in real-time using aerial footage captured by drones, allowing for the plotting of detection locations on a map. It is optimal for the rapid location estimation of fire spots and the estimation of the burn area, which have become pressing issues in recent years regarding forest fires. Additionally, by combining it with a video transmission system, it is possible to share footage in real-time with relevant parties. The flame detection by Grabee is a new drone utilization solution aimed at firefighting activities during forest fire outbreaks.
