Dahua Launches Enhanced Anti-Corrosion Cameras for Extreme Environments
March 26, 2026 / Hangzhou, China. Dahua Technology, a world-leading video-centric AIoT solution and service provider, has officially introduced its IPC/PTZ Enhanced Anti-Corrosion Aluminum Alloy Cameras and Enhanced Anti-Corrosion SUS316L Stainless Steel Cameras， engineered to deliver reliable surveillance performance in highly corrosive and hazardous environments such as coastal ports, transoceanic bridges and oil depots.
Enhanced Anti-Corrosion Aluminum Alloy Material
A key highlight of IPC/PTZ anti-corrosion equipment is its upgraded aluminum alloy, which offers exceptional resistance to corrosion. Even after 2,000 hours of neutral salt spray testing, the material maintains surface integrity. Its refined microstructure, with significantly reduced grain size, enhances strength and durability while lowering overall lifecycle costs in demanding environments.
Dual Anti-Corrosion Processing Technology
The IPC/PTZ anti-corrosion cameras incorporate a dual-process system combining passivation strengthening and anti-corrosion coating. This approach significantly reduces corrosion rates, improves coating density, and minimizes internal material degradation. As a result, the product achieves greater resistance to various environmental stress, ensuring stable performance over extended periods.
Full-System Durability with Reinforced Components
Dahua has extended corrosion protection to every component of the equipment. High-performance screws made from stainless steel with Dacromet coating provide enhanced resistance to rust and wear, ensuring that the entire system (not just the housing) maintains integrity in harsh conditions.
Integrated Corrosion and Explosion Protection
The enhanced anti-corrosion SUS316L stainless steel cameras incorporate an integrated protection that combines corrosion resistance with explosion-proof design to form a closed-loop safety system. Engineered to meet high-grade safety standards, both the devices and their accessories are well suited for high-risk environments such as oil depots, oil/gas pipelines and refineries. This capability is further reinforced by an advanced three-layer protection framework, consisting of a stainless steel substrate, an anti-corrosion surface treatment, and a fluorocarbon paint coating. Together, these layers provide a comprehensive barrier against corrosion, chemical exposure, and environmental wear, while ensuring compliance with stringent certifications, including 5-H, and ATEX/IECEx for both corrosion resistance and explosion protection.
