The worldwide video surveillance market is growing rapidly due to the growing demand for visual perception of the surrounding environment (both inside and outside of homes, buildings, factories, businesses or infrastructure). However, the number and location of deployed systems is more limited by the economics of the video camera supplier and the complexity of the infrastructure used to deploy, manage and monitor these systems.

The last major breakthrough in the video surveillance industry was the result of some major improvements in image sensors and digitization, as well as the widespread adoption of Internet Protocol (IP) networks. Right now, some powerful new technology trends—such as the use of 3D NAND-based microSD cards such as those offered by Micron—are expected to change the landscape of the video surveillance industry again, driving a new wave of development for all players.

New Trends Drive Video Surveillance Industry Development

The rapid development of technologies such as mobile, storage, the Internet and the Internet of Things is driving innovation in industry and technology trends, and the video surveillance industry will greatly benefit from these trends in the coming years. We should pay attention to how these trends support each other, which is expected to bring about a virtuous cycle of growth and adoption in the video surveillance market.

Further commercialization of high-resolution image sensors

Nearly 5 billion CMOS image sensors were delivered to customers in 2016. Although most sensors are used in mobile phones, other applications such as video surveillance can also benefit from the economies of scale in sensors. Nearly half of these products have sensors with a resolution of 5 megapixels or more, providing extremely high-resolution images.

Benefits for Video Surveillance

Video cameras can have unprecedented high resolutions (5 megapixels and beyond), increasing information gathering capabilities and enabling better video analytics without increasing costs.

The advent of a new video compression codec

The transition from 2k (1080p) to 4k in consumer-grade video has also increased the adoption, cost-effectiveness and availability of H.265/HEVC-grade codecs, addressing the need for large-scale compression of high-resolution video for storage and transmission .

Benefits for Video Surveillance

For video surveillance use cases, many camera OEMs are adopting advanced compression and dynamic bitrate technologies that provide greater compression than H.265 and reduce the size of the video that needs to be stored and/or transmitted.

Adoption of 3D NAND-based Flash Storage Technology

In recent years, flash storage technology has shifted from a planar implementation to a vertically stacked 3D implementation. For example, Micron’s 64-layer 3D NAND technology can pack 32GB of storage on a tiny 59mm silicon wafer with a density of up to 4.3GB/mm. This density is 5 to 6 times that of planar NAND technology with the same performance. 2 Micron can now create highly reliable video surveillance microSD cards with ultra-high densities such as 128GB and 256GB.

Benefits for Video Surveillance

Surveillance cameras that support microSD card slots have been around for some time, but due to the reliability and capacity limitations of the previous generation of consumer-grade memory cards [JG1], such slots are rarely used. Micron’s new industrial-grade microSD card for video surveillance edge storage gives system designers unprecedented flexibility to design and cost-optimize large distributed surveillance systems. These microSD cards feature extremely high capacity and reliable chip-level data storage, making it possible for the first time to store days’ worth of video on the camera side.

Advances in AI algorithms based on computer vision and deep learning and falling implementation costs

In general, the cost of image and pattern recognition-based analytics has been decreasing exponentially. In the fields of medicine and autonomous vehicles, the factors driving this cost reduction are diverse, however, along with various deep learning frameworks, algorithms, and semiconductor system-on-chip (SoC) integrated circuits ( The introduction and maturity of IC), the vast majority of industries, including video surveillance, have benefited a lot.

Benefits for Video Surveillance

Manual video surveillance is expensive, error-prone, and not scalable. Cameras can now perform most video analytics with centralized capabilities dedicated to more advanced functions without having to send high-resolution video to a central network video recorder (NVR) or server, avoiding high bandwidth and central storage costs . This means that users can perform advanced video analytics in-camera to gain better insights, decisions and outcomes from data sources.

Cloud-based device deployment and management services grow and adopt with transition to IoT

Thanks to IoT, sensors and smart devices can now be deployed across multiple verticals such as smart cities, transportation infrastructure, factories, businesses, and homes. However, IoT’s requirements for scalability and manageability are driving a shift to cloud-based device deployment and management models. In this model, devices can be provisioned, authorized and managed directly from the cloud without the need for separate physical networks and intermediaries.

Benefits for Video Surveillance

Many use cases will benefit from the ease of use and economics of a direct cloud deployment model for video cameras, and the required infrastructure and tools will evolve to support IoT deployments. In the DIY segment of the consumer market, this model will also help accelerate the adoption of devices such as Google® Dropcam® and Netgear® Arlo™. Now, with edge storage and/or enhanced edge intelligence in cameras, this model will help professional-grade surveillance maintain professional-grade services and service-level agreements (SLAs) while reducing total cost of ownership. Consumer-grade devices run on public clouds, but professional-grade deployments can use a combination of private and public clouds to benefit from the overall ease of use and cost advantages of the cloud.

“Marginalization” with Micron Technology

With its leadership in 3D NAND technology, Micron is also at the heart of enabling edge storage applications in video surveillance. Numerous industry reports have documented the multiple benefits of using edge storage in cameras, including Micron’s innovative edge storage solutions technical brief for the video surveillance industry.

On October 31, 2017, Micron Technology announced the expansion of its industrial-grade microSD card family with new 3D NAND-based 128GB and 256GB capacities. These products help move the industry forward, making edge storage in cameras the primary video storage, or at least an important part of hybrid deployments when combined with traditional NVRs so that cloud-based deployments can be Dramatically reduce bandwidth and storage and maintenance costs, and increase deployment flexibility.

The size of the actual video created under a particular deployment can vary widely. OEMs and system integrators use a variety of tools to manage data size, such as selecting camera resolution, video compression codec used, frames per second, variable bit rates, and recording time required by the situation. Additionally, the number of days of footage to retain for evidence management purposes varies, depending on country legal requirements, type of use case, and SLA between the system integrator and the end customer. The table below shows the number of days of marginal storage possible with a microSD card of a given size when using constant bitrate recording throughout the day. As shown, these cards enable many days of storage, which gives system integrators a lot of flexibility in overall system design and how functionality is utilized.

Say goodbye to blurry videos

Previously, there were a number of factors that prevented the deployment of high-resolution cameras for video surveillance: the cost of the camera, the cost of bandwidth from the camera to the NVR, the storage cost of high-resolution video, and the cost of video analytics. Affected by this, the industry can only provide blurry and low-quality video, which in many cases cannot meet the real needs of video surveillance. By adopting a new and more affordable cost structure for high-resolution cameras and electronics, system integrators can intelligently analyze and store video locally at the edge node and ensure that only relevant data is sent to the cloud/central site, without affecting the video Minimize the cost of bandwidth and equipment required for these deployments without sacrificing quality. End the blurry surveillance video quality of the past 20 years.

Enrich the embedded ecosystem

Micron has long been a leader in the embedded market, developing application-specific products that create significant value for customers and end users. In addition to bringing new and innovative products to market, Micron invests heavily in bringing to market the right channel partners to develop and support the global market and customer base.

To more quickly meet the unique needs of video surveillance customers, including consistent recording performance over years of use, Micron recently announced a partnership with the Shenzhen Security Industry Association and Chinese channel partner Jinyu Global. The partnership with Jinyu and the Shenzhen Security Industry Association helps ensure Micron Technology meets industry standards while expanding its storage offerings and increasing its presence in China and beyond.
