Needless to say, video captured by security cameras must be properly stored. Storage, then, becomes a critical part in a video surveillance system. To further readers' understanding of storage for video surveillance, we’ve compiled this resource guide featuring exclusive articles, suppliers’ news and product information published on asmag.com. It’s our hope the guide will provide more insights into video surveillance storage and help readers make a more informed decision when selecting a storage solution.

Why is storage important for video surveillance?

 
Storage has gained importance due to an increasing amount of video data generated by video surveillance systems. More and more, cameras are going UHD, producing high-resolution video. At the same time, more end user entities, from governments to private businesses, are requiring longer video retention for forensic and investigative purposes. Further, with the dominance of AI, more video is needed to train AI systems to be more intelligent. All this contribute to increased demand for advanced and reliable storage solutions.

What storage device is best for video surveillance?

 
The network video recorder (NVR) remains the most popular storage solution in video surveillance. Today’s NVRs come with better processing capability, are more reliable and ensure little data loss. With cloud gaining importance, NVRs now also have cloud capabilities. In terms of storage medium, the hard disk drive (HDD) is still the mainstream. Yet solid state drives (SDDs), which are smaller, faster and less energy-consuming, are also gaining ground.

Hyper-converged infrastructure

 
More and more, storage has gone beyond the conventional hardware-centric approach. This is because increased video data is putting more pressure on traditional video recording infrastructure, which is typically racks of network video recording servers (NVRs). This hardware-centric approach is more susceptible to downtime, data loss, and degraded performance, and is complex and costly to manage at scale.
 
To solve these problems, more vendors are launching storage solutions using a software-centric approach. The Unified Surveillance Platform by Quantum, for example, replaces racks of NVR servers with a single unified compute and storage software platform for video recording and analytics. The software uses patented video data reduction techniques to record and store video data at the highest performance with the least amount of hardware required, allowing customers to host more than 10,000 cameras on one single system. This hyper-converged infrastructure (HCI) approach to data protection and automatic failover across the entire cluster delivers the highest uptimes, practically eliminating data loss or downtime due to a failed component or NVR server. With USP, customers can go from racks of NVRs to one simple system that is easier to manage, more cost effective and can keep up with the rapid growth of video data.

How to choose the right solution for video surveillance storage

 
Choosing the right solution for video surveillance storage can be based on various factors. One of them is the camera count at the end user entity. A video surveillance system with a small camera count (up to 32) inevitably needs a storage solution that’s different from one with a large camera count (500-1,000). When determining the amount of storage space needed, a storage calculator can be useful. According to Alastair McLeod, CEO of Veracity, the best and most accurate way to estimate the storage required is to use a calculator using the average bitrate per camera as an input – for example, a full HD camera at 30 frames per second and using H.264 compression will produce about 4 Mbits for a reliable high quality video stream.

On a related note, asmag.com has a storage calculator page that provides the necessary resources for systems integrators who need storage or bandwidth calculation to make decisions about camera placements and lens requirements. Click here to go to the page.

On-prem or cloud storage for video surveillance?

 
Oftentimes, users are faced with the choice of whether to store video on-premises or in the cloud. Each has its merits and disadvantages. On-premises storage solutions, while expensive, are owned by the end user and do not require high-speed and reliable Internet transmission. Cloud, on the other hand, eliminates the need for expensive equipment purchases but needs stable Internet for reliable data transmission. The cloud service provider will also charge a fee for storage. More and more, users are eying hybrid solutions so that, for example, the more recent video could be stored on-premises, while older footage may be archived in the cloud at a lower resolution. For those who find it difficult to choose between on-prem and cloud, hybrid may be a more viable alternative.
