IP storage for video surveillance

Demand for video surveillance has increased considerably in enterprises. This has been due to reasons such as the need to meet compliance standards or the fact that enterprises can easily deploy IP cameras and use their existing cabling for carrying video signals. Enterprises are readily deploying web based IP surveillance solutions as they provide several advantages over traditional CCTV solutions. Administrators can remotely view and manage IP surveillance systems, the system itself is fast, ease of use, etc. Further, IP video surveillance is also being used as proof in lawsuits and at times is required to meet compliance. However, it also causes problems such as storing images generated from IP video surveillance, as even a single IP camera can generate more than 20 GB of data in a single day. Also, as a video surveillance system performs constant write operations on a storage disk, using common storage devices such as NAS can degrade the performance of a video surveillance system as these devices are designed for environments where balanced read/write operations take place.
