Video Storage: 5 Reasons to Consider Purpose-building
A vital consideration for any network video solution is video data storage. Many mission critical network video solutions are currently scaling in size and taking advantage of higher resolutions and frame rates. This is creating immense video data storage needs. In order to meet the storage demands of network cameras, and users viewing live and recorded video; considerations for purpose built storage solutions are crucial.
Streaming video is often considered ‘just another form of data’ however streaming video has certain demands and characteristics that differentiate it from other data forms. These characteristics are the reasons you should consider purpose built storage over traditional data solutions.
- 1. Massive database size needs
- 2. I/O-intensive operations
- 3. Intolerances of system latencies
- 4. Constant bit-rate streaming
- 5. Demanding operating environments, such as temperature, vibration, bit-error rate and more.
Because of the intrinsic nature of streaming video, each of these five areas requires a purpose-built approach that takes into account unique needs, capabilities and system demands. There are many external storage options available, including direct attached storage (DAS), network attached storage (NAS), iSCSI, Fibre Channel and storage area networks (SAN).
An emerging trend is edge or on-board storage, which stores audio and video recordings within cameras, typically using an SD card. Edge storage is particularly beneficial for mobile security or applications that experience network connection interruptions. Edge storage is an excellent complimentary enhancement to central storage to facilitate comprehensive and seamless video coverage building additional redundancy in the solution.
