This is a millimeter-level displacement monitoring product based on satellite positioning technology. Design background: We have seen that existing similar products have problems such as insufficient monitoring accuracy, data warnings requiring manual review, high requirements for the installation environment, low installation efficiency, and high user costs. Purpose: Integrate visual modules to achieve early warning of geological disasters, tunnels, bridges, etc. Through design innovation, we can achieve the advantages of low cost, easy deployment, unmanned, fully automatic, and all-weather.The RTK differential positioning technology enables millimeter-level displacement monitoring, and the integration of high-definition full-color visual modules enables video review. The integrated 4G/5G communication module enables remote video inspections, and the low-power design combined with the solar power supply system eliminates the hardware requirements for the installation environment.As a video-integrated GNSS product, the incorporation of a visual module sets this product apart from many traditional devices. It maintains excellent volume control compared to traditional devices, balancing the need for a larger field of vision in the visual module while ensuring the overall product integrity. Its flat cylindrical curved surface design minimizes interference from outdoor weather conditions.This product can provide comprehensive detection and early warning for geology, landforms, buildings, and places of cultural value.Through precise displacement monitoring and video surveillance functions, the product enables monitoring of data related to reservoir dam deformations, structural deformations, geological deformations, etc. This allows for early warning of accidents such as dam failures, building collapses, landslides, and mudslides, preventing greater losses. The 4K full-color visual module is unafraid of darkness, featuring 4x optical zoom and a 360-degree wide viewing angle. Video surveillance eliminates the need for personnel to venture into high-risk areas, while also avoiding false alarms caused by wildlife interference and abnormal weather conditions.
