As of my last knowledge update in October 2023, providing an exact number of CCTV cameras worldwide is challenging due to the lack of comprehensive global data. However, estimates suggest that there are over 1 billion CCTV cameras in use globally.

This figure includes cameras deployed in various settings, such as:

- Public spaces: city streets, parks, and public transport systems.
- Private properties: homes and businesses.
- Roads and highways: for traffic monitoring and safety.
- Government and security installations: such as airports and critical infrastructure.

China is known to have the highest number of CCTV cameras, with estimates suggesting that many cities have upwards of several hundred thousand cameras for public surveillance. Other countries, including the United States, the United Kingdom, and India, also have significant numbers of CCTV cameras.

It's important to note that these numbers are continually changing as more cameras are installed and as technology evolves. For the most accurate and current data, it's advisable to refer to studies or reports from security industry experts or relevant governmental agencies.
