Central recording using recording servers

Advantages:

Storage system technology can be chosen freely from different storage vendors. This allows the surveillance system designer or administrator to choose the storage system and technology that best fits their needs and budget
The storage can be scaled and expanded to virtually infinite size, by using the right storage technology
The performance of the storage system can be tailored to the exact needs of the video system
Standard storage redundancy technologies can be used to ensure that the storage system is always online and that data in the form of recordings is not lost in case of failures

Disadvantages:

Video and audio will not be recorded if the recording server is down, either due to a system failure or due to maintenance, unless the surveillance system is protected by a failover recording solution like the failover recording server offered by XProtect Corporate and XProtect Expert
