Best Practices For IT Network Supporting 500 Cameras

I need to propose to my client on the best practices of IT infrastructure required for IP based CCTV system for about 500 cameras.

Are the 500 cameras going to be connected to the existing network or are you building a new dedicated network for the CCTV system?

Are these cameras in a single building or are they distributed across multiple sites?

Are all the cameras coming back to a single spot for recording or will there be multiple recorders throughout the building(s)?

What resolution / frame rate are you looking to do? SD, 2MP, 5MP, Other?

Let us know and we can provide better feedback.

agree with john, we need general information (besides camera count) to give the recommendations.
