Make every camera count.
Security in China is an independent English-language resource for planning camera systems and understanding documented equipment specifications. It brings practical CCTV calculations, horizontal coverage planning and source-linked product research together.
Useful tools, without invented certainty
We show the formula behind a calculation, the document behind a specification and the gaps behind a compatibility assessment. A matched codec or a shared protocol is useful evidence, but it does not prove that every feature of a camera and recorder will work together.
