Even in areas with no access to a power supply, the solar powered radio warning system ensures complete safety management in dangerous construction areas such as disaster prone areas and erosion control works.
CDT-TX-02M, CDT-RX-02M, WT-01
The construction area on the river and the general mountainous area around it carry a high risk of mudflow and landslides. While keeping construction workers safe, for the local residents in the area an emergency warning system that can immediately supply a warning is used.
