Some misconceptions about video storage solutions!

Video Storage solutions in security surveillance field have their share of misconceptions and missed opportunities. In this article, we will take them one by one from a manufactures point of view to set the record straight.

SSDs will take on hard drives soon- There is a strong buzz going on in the video surveillance field that HDDs will get replaced by solid state drives soon. And all the future solutions in this field will be SSD based in future.

While it is true that the slashed pricing of the SSDs are adding fuel to this talk, factually speaking, cost-per-gigabyte for HDD actually goes down as capacity increases. Therefore, for a 3 terabyte drive, it only costs $30 more expensive than 2 terabytes, for instance, while 2 terabytes costs almost $40 more than 1 terabyte.

Whereas, the economics of SSD are different, twice the capacity means double the cost. Due to these economies of scale, HDD will continue to win in the foreseeable future as the technology of choice.

There is also a misconception that all the HDDs are the same, which means that digital storage solutions are often selected based on cost alone rather than suitability. But this is not true in general. Surveillance related hard drives often have the trait of working for 24 hours a day and that all round the year, due to the fact that they applications demand such work functions.

The other misconception among end users is that they are missing a major opportunity to optimize the efficacy of surveillance systems, with a “one storage solution fits all” approach. As the uses of surveillance have expanded, the storage solutions available have similarly evolved, tailored to these new functions. Therefore, it doesn’t make sense, if the IT admins start going with one storage solution fits all approach.

The very first decision to make will be retention time and storage provider, says Mo Tahmasebi, CEO and President of DNF Security. He adds that before a solution is provided to the user, he/she needs to be first educated on the way one choice impacts another. For instance, if a 5MP camera is backed up by 30 days retention, then this decision can only put a wrong step on the budget factor. Here, the user can only afford 8 days of storage instead of 30 days.Therefore, after knowing retention time and having an understanding of the effect that camera choice has on it, a storage solution needs to be figured out.

Mo Tahmasebi adds that all storage is not created equal, and you don’t have to spend 50% of the budget to store your video. This clear hints that each missed opportunity to educate, to sell with a consultative bend, is a missed opportunity at a wide sale.

DNF Security TSO NAS device, which can be used as a video storage, as it uses hard drives meant for surveillance, and requires very little power, and even a hard drive failure can be handled with no panic required. Storage has followed IT into the complex when it has needed to remain simple. Therefore, DNF Security Twin Scale Out NAS is a reliable storage system that protects data when not needed and produces it when it is needed.

“As cameras and video management systems become more and more complex, storage needs to be simple, straightforward and something that the end user can point to and say ‘now that I understand”, said Mo Tahmasebi, CEO and President of DNF Security.

He added that this gives the user license to accept more complexity in other areas, to maximize the use of complex technology, while knowing that the storage systems, which are on-premises, are utterly solid and totally reliable. At the same time, Mo added that the system must be highly scalable and cater to all the future storage needs on an enterprise surveillance environment. His company offered TSO NAS does the same thing as it offers the ability to add drives per linear performance.

Generally, if a video system fails, the following reasons are most often cited:

  • Drives kept failing and overall system performance tanked during rebuilds.
  • More/higher resolution cameras are added.
  • Playback requirements increased.
  • Retention times increased.
  • Video analytics are added.
  • Local storage at each site was too expensive to maintain and scale.

All of the above stated issues can be avoided by going with a consolidated storage platforms like DNF Security TSO NAS that delivers full performance, even in outage conditions, and is proven to scale performance and capacity to accommodate increased workloads as well as data growth.
