IP SECURITY unless there is an incident, will be kept for a certain timeframe and then deleted. There will also be video that will be meaningful for a short time frame, as well as some that must be kept for longer.’ Specialist storage architecture With so much data to capture and preserve, performance of the storage solution is an important consideration. However, it’s not just a case of committing the data to disk as Wayne Arvidson, vice president, Intelligence, Surveillance & Security Solutions at Quantum, says: ‘There is a lot of misconception around performance. Video is entirely different to IT data and so the storage solution must be architected differently. ‘It is vital that the storage solution takes into consideration increasing video resolution, as technology continues to improve, as well as the fact that more and more footage is being stored for more than just security purposes; being used for analysis to improve business processes, customer satisfaction etc. Tiered ‘With so much data to capture and preserve, performance of the storage solution is an important consideration.’ architecture creates a balance around storage needs versus days retained.’ It is this ‘tiering’ criteria that will define the type of storage chosen, for example, tape is a very good, cheap, non-corruptible solution for the video that needs to be stored for long periods of time, whereas hard drives are much more appropriate for video that needs to be accessed more frequently or used for analysis. Jermaine Campbell, North Europe sales manager at Western Digital, says: “When considering the type of drive, first, is the drive designed for 24/7 power on hours at 80 per cent or higher write versus read? Surveillance storage is about writing data consistently and reliably. Second, does the drive meet the required workload? ‘A selection of drives are built to endure a higher amount of data written to the drive per year. This is the equivalent of driving your car for many miles at 7000rpm or at 3000rpm. Third, does the brand carry a good reputation for reliability, if you can tell a customer ‘this DVR is using brand X’ and the customer recognises that for the right reasons, then that helps with customer confidence.’ Storing video the right way Organisations must comply and contend with many different external influences specific to them. Factors such as litigation, legal, insurance and health & safety, are driving the need to store video for increasingly longer periods, preserving the video in a way that ensures it is admissible evidence. It will defeat the purpose of the solution if, for example, video is thrown out of court for not being compliant. To sum up, storage plays a vital role in a surveillance system. It is as important as the cameras and the management system itself. The whole point of storing video is to preserve it, to be able to retrieve it easily, quickly, and in a format that is easy to use. Video storage is not hard, but it is complex, as there are many requirements to take into consideration, which must be addressed in order to harness the true potential of video. 32 | May 2017 IP SECURITY unless there is an incident, will be kept for a certain timeframe and then deleted.
