I would like to have more info about Video Over IP Recording. How do I compute the amount of storage a camera needs to record? For example, to record cameras 3Mbits, 4CIF for 30 days. There are some information in the CCTV Brochure how much storage the camera needs for a certain specification, but I need to know how they compute it.
Another issue is that most of the time, it ends up needing a big storage especially when the customer requires 30 days recording. The bad thing is that recording sometimes become the same price as your CCTV equipments.
What is better decentralised recording or centralised recording?
