3 The Video Surveillance Market Demand remains high for video surveillance solutions. The world market for video surveillance equipment will surpass $16 billion in Yet, the market is still not saturated. In a recent report on the installed base for video surveillance equipment, IHS estimates that there is one camera installed for every 29 people on the planet. As well as new installations, retrofits and upgrades are a significant part of the market, a market which globally is expected to see a compound annual growth rate (CAGR) of 20% in new camera unit shipments from 2014 to In 2016: 2015 IHS In addition to the increasing volume of surveillance cameras shipped annually, technological advances mean each new generation of surveillance cameras benefit from improvements in image (video) quality. Image quality is a complex matrix influenced by many different elements. Whilst there is a strong relationship, resolution is not always analogous to image quality and it s important to consider other elements including (but not limited to): pixel density of scene, frame rate, and wide dynamic range. However, camera resolution is one of the most marketed components of modern surveillance cameras; it s often the first specification item that s quoted by manufacturers so it s a good measure to illustrate the general trend of increasing camera specifications in the industry. 2

4 Exhibit 1 shows the forecast revenues from global network surveillance cameras by resolution to Exhibit 1: Global Network Surveillance Camera Shipments by Resolution In addition to the market increase in network camera resolution the following is also true: HD compliant 1080p 25/30 fps cameras have firmly established themselves as the minimum expected from new cameras not just in the network camera market (Exhibit 1); in lower priced, small channel count installations HD CCTV has emerged as the replacement for many remaining standard definition analog cameras. Panoramic and 4K network cameras are two further storage hungry high growth product categories. Here IHS is also observing rapidly falling average prices and increasing shipment growth rates. 3

5 Generally, improved image quality means more data is generated. Exhibit 2 shows on average the data produced in just one day by all the new video surveillance cameras installed worldwide. The increases forecast year-to-year are a factor of the increasing camera shipments and the uplift in their specifications. Exhibit 2: Challenge of More Data Being Generated 2015 IHS Whilst there are continuing advances in the use of pre-recording analytics and compression technologies, which can provide a trade-off between image quality, bandwidth and storage requirements, these cannot completely mitigate the associated increase in data from an increased number of higher resolution linked cameras. In addition, the demands for data retention times are growing as some endusers require their data stored for longer. Aside from security and protection, longer retention is being driven by other commercial factors. Threat of litigation from civil law suits have led to some end-users storing video for longer. For example in some large North American retail deployments the cost of longer retention offset against potential costs of legal settlements. Longer retention also means a larger dataset for post-recording video analytics for both security and business insights. 4

6 The increase in data produced by surveillance systems and the increased retention demands have meant the demand for video surveillance storage has increased drastically. The problem for end-users is how to manage and store the increased amount of data IHS Options and Solutions With more data being generated from a wider variety of sources a smarter allocation of resource is required, system design must follow accordingly. What should end-users consider regarding their system design? The storage in a video surveillance system should be viewed in a similar way to cameras. Different camera models in a system are selected for different requirements, yet all capture video. Storage can be thought of in the same manner; different types of storage can be leveraged in one system. There is rarely a fixed value or frequency of access for recorded video surveillance footage over its lifetime, yet, too often a one-size fits all solution is implemented. To gain more insight and an increased return on investment from video surveillance data, a storage solution must balance high performance, high capacity and high retention. These three parameters can be flexed to provide the best trade-off between budget and mission whilst minimising sacrifice of redundancy, accessibility or scalability. When planned from the early stages of the project the storage solution can address as much of the mission criteria as possible without using a disproportionate chunk of budget. Analysis of the budget should take account of: What legislation and guidance do you need to comply with regarding data retention? What is the potential cost if you do not? What value is there on the insights you can gather from the data you collect? 5

7 Design should go beyond basic capacity planning for which there is an abundance of sufficient calculators. End-users and integrators should also consider some of the following key points regarding what they require from their storage: The majority of video surveillance data is never reviewed. Is your system geared to a heavy write focus? How does the value of your data change over time? Is there a data sub-set which is most mission critical or likely to require the most access? Can you easily move data in and out of this category? Do you want access to archiving, back-up and longer term retention in the same system? Would it be useful to pool data from multiple types of video devices (e.g. fixed, vehicle or body worn video surveillance cameras) and other sensors in one place? How easily can your solution support expansion? Use of storage tiers in video surveillance has previously meant just a separate archive or directly attaching add-on capacity to recorder appliances. We re now seeing a multitude of options designed for video surveillance, which pull together different storage tiers (in some cases storage media) into a unified platform. This allows more efficiency in varying how recorded footage is treated throughout its lifetime.

8 This approach can be leveraged into localized individual systems or scaled out to large distributed systems with anything from a city to country wide scope. Regardless of the size of your video surveillance system applying these principals to the underlying architecture can gain you a more effective use of your budget to balance between performance, maximum retention and potential ROI. Key Conclusions Video surveillance is evolving not just in terms of higher specifications; there are no longer single purpose systems. Inputs from multiple sensor types with different analyses and management mean multiple uses for data. In any budget for maximum optimisation between performance, data retention and potential ROI build the system around the back-end architecture enabling the most efficient data management and storage. 7
