Dahua Launches Enhanced Anti-Corrosion Cameras for Extreme Environments

2026-03-26

Dahua Launches Enhanced Anti-Corrosion Cameras for Extreme Environments
Enhanced Anti-Corrosion Cameras
Defying Corrosion,Enduring Protection
Professional Anti-Corrosion Protection
Enhanced Anti-Corrosion Aluminum Alloy
Enhanced Anti-Corrosion 316L Stainless Steel
Superior Reliability in Demanding Scenes
Pain Point
In coastal ports, bridges, and similar settings, high humidity and salt spray can easily lead to corrosion of conventional surveillance equipment. This significantly impacts the stability and safety of camera operation, causing problems for users.
Corrosive Scenarios
Peeling Coating
Surface Rust
Seal Failure
Anti-Corrosion Protection Level
Non-Corrosive area
No obvious corrosive factors, such as inland cities, ordinary office buildings, etc
Basic Protection
Coastal areas away from 2 km
The area 2 km away from the coastline such as coastal scenic area or peripheral areas of plants.
Moderate Protection
Professional Protection
Coastal areas 2 km or closer
Extreme salt spray environments and weak acid and weak base environments, such as ports, sea-crossing bridge, etc

SUS316L Stainless Steel Substrate
Three Key Anti-Corrosion Processes
SUS316L Stainless Steel Substrate
  • Cr/Ni/Mo composition for corrosion & intergranular resistance
  • High strength, hardness for flameproof performance.
Anti-Corrosion Surface Treatment
  • Polishing: Removes burrs & oxides, minimizes rust sites
  • Passivation: Forms a stable, dense film to isolate metal from corrosion.
Fluorocarbon Paint
  • Dense, clear, weatherproof barrier
  • Maintain bright stainless steel appearance;easy to clean
