Smart Video Surveillance
See Your World in a New Way
One of the fastest growing data storage markets today, smart video is often used for and associated with security and/or surveillance. With advancements in artificial intelligence (AI), machine learning (ML), and real-time analytics, the possibilities for smart video now go beyond just surveillance, such as the following.
Retail
Streamline business operations and minimize opportunities for theft.
Transportation
Improve traffic flow for pedestrians, bicyclists, and vehicles.
Smart Cities
Reduce patterns of congestion and enhance overall safety.
Western Digital answers this growing need with a specialized line of smart video storage purpose-built for demanding, 24x7 operating environments. Our solutions provide reliable storage at each camera and uninterrupted operations regardless of network availability. With a full range of products from microSD™ cards for in-camera storage and surveillance-class hard drives for video recorders, to enterprise-grade devices and platforms for back-end storage and analytics, you can customize your system to fit your smart video needs.

Key Considerations for Each Smart Video Component
Most standalone smart video systems are composed of three main components.
Now let’s dive into key considersations for each component.

Capturing and Organizing Footage
Once you have set up your smart video system, it’s time to start capturing footage. There are two ways to do this: continuous monitoring or motion-triggered.
- Continuous monitoring means your video capture remains on at all times and records every minute of footage to the DVR or NVR. This can eat up capacity quickly on your NVR, so make sure you have a big enough hard drive (or multi-bay system) installed in your recorder to accommodate as much footage as needed.
- Motion-triggered means you can set capture to happen only when the camera detects motion in its field of vision (provided your camera can detect motion, most new ones do). Some systems allow you to manage ‘hot spots’ for video triggering. When movement is detected in a hot spot, it automatically triggers recording.
Surveillance footage is captured on the internal hard drive as long as there is space to do so. Once maximum capacity is reached, the NVR will start rewriting the disk from the beginning, erasing any previously recorded footage as it continues. To avoid losing captured footage you can either:
- Swap out the internal drive with a fresh, blank, formatted drive.
- Expand your capacity by adding more drives (if you have available bays in your system).
- Back up the old footage and erase or overwrite the drive with new recordings.
Backing up your footage on a regular basis to a separate device is crucial to maintaining a reliable archive of your captured surveillance. A WD My Book desktop storage is an ideal device to perform this task. (Tip: Choose a model that exceeds the capacity of the drive you are backing up.)

Smart Video Now and Tomorrow
Smart video is the evolution of traditional surveillance. Data collected by cameras can be leveraged by smart apps like facial recognition. Smart video uses cameras to analyze incoming video in real time to extract valuable insights that allow decisions to be made without human intervention. That’s how you can unlock your phone with your face without entering any data manually.
Another example of smart video is smart cities. Smart cities use different types of electronic Internet of Things (IoT) sensors and devices to operate municipal cameras, control signal lights, reduce congestion and pollution, and improve people’s lives. Insights gained from that data are used to manage assets, resources, and services more efficiently. When collected information is pooled together, it’s referred to as big data, which can then be used to improve the operations across the smart city.
In smart factories, smart video can detect manufacturing inefficiencies, and in some cases, perform better quality control. In smart retail, analyzing foot traffic can help identify prime locations for product promotion and placement.
So, how does smart video work? Smart video employs artificial intelligence (AI), either in the NVR or on the camera. AI requires deep learning and that can take place in the NVR or more likely, in a deep learning server on the back end or in the cloud. Deep learning requires massive amounts of reference video data to improve the effectiveness and efficiency of the AI.
Smart video can impact every aspect of surveillance from cameras, to recorders, to back-end servers. Consider that more effective AI requires higher resolution video, higher frame rates, and more visual detail. All this leads to the need for more and more reliable data storage.
