The network video surveillance system provides three storage methods: front-end, center and client. The general principles for determining storage locations are as follows:
Front-end storage: If users have high requirements for storing images in real time and the reliability of front-end equipment can be guaranteed;
Central storage: If the front end does not have a storage function, the central storage is generally used, and the central storage can be used as a backup of the front end storage
Client storage: generally used as temporary storage of video images: such as snapshots and manual recording.
