Ray Chan

Ray Chan has spent over a decade in the security and surveillance export industry, helping overseas buyers source full-color night vision cameras, NVR systems and complete CCTV kits from Chinese factories.

His buying guides focus on the questions real importers ask — Power over Ethernet basics, what an NVR actually does, how full-color night vision differs from traditional infrared, and how to choose a camera manufacturer you can trust. Every article is grounded in factory-level specifications, not marketing fluff.
