Rise of Edge Storage in Distributed Video Surveillance

Demand for HD CCTV cameras and recorders has grown rapidly in recent years. In fact, IHS forecasts that in the professional market, shipments of HD CCTV cameras will grow from fewer than 0.2 million units in 2012 to over 28 million units in 2016.

StorageReview-EMC-Surveillance-VNX-VSSStorage configured for video surveillance is gaining more industry attention. The RAW capacity shipped of SAN, NAS and DAS storage used for video surveillance is increasing at around 40% each year. The traditional boxed appliance model, (born out of the death of the VCR) typically included DVRs in a capacity to suit and perhaps external DAS for extra capacity; this was simple and it worked. Yet video surveillance has evolved and this type of approach has been insufficient for an increasing percentage of users.

Average camera resolution continues to increase. HD-compliant 1080p 25/30 fps cameras have established themselves as the minimum expected from new cameras. Panoramic and 4K cameras are two further storage-hungry high-growth categories. In addition to the above in some countries for certain segments like Energy & Utilities the recent laws is asking video data to be stored for a minimum of 90 days.

All the above reasons are driving Customers to look out for an Open Standard Video Surveillance Platform and we at EMC had envisaged this couple of years back which led us to launch the VSS1600 our second generation purpose built Enterprise Storage System for Video Surveillance Workloads this month (our first gen was VSS-100).

Our deep understanding of this industry is due to the fact that we have invested heavily on Surveillance Labs running at Durham for over 10 years and most recently in Bangalore, which helps us keep a eagle eye on this fast growing industry. Below are some of our learning from the labs

  • Surveillance Workloads are “Write” heavy and hence the need for the Storage System to be Optimized for Write heavy workloads. The reason this is important because most of the Global Top OEMs Storage systems have been optimized for IT Business applications like RDBMS, ERP and would act wobbly on a Video Surveillance workload unless properly validated.
  • Every VMS Applications is different and hence the impact on the storage systems varies from VMS Application Vendor A to B to C. Some of the VMS Applications are Optimized for Block Storage, while some of them are optimized for File Storage (NAS) and some of them like the Body Camera Applications are optimized for Object based cloud Storage System.
  • Some of the VMS Applications work on Server Virtualization and some prefer not to.
  • Some IP Camera’s stream to the Storage System directly without the need for a recording Server.

Since a year our VSS Storage Systems have gone live at Large Airports, IT/ITES Campus, Auto Manufacturing Units, Police Stations, Data Centers and the count is Rising……
