David Henderson, Director, Industrial/IMM, Micron provides an in-depth analysis of how edge AI can be best applied to memory and storage solutions
Why do we need AI at the edge in video security applications?
AI implementation in video security applications should consider the factor of architecture from end-to-end, edge-to-cloud perspective. With the increasing processing power and algorithm development at edge devices in recent years, the AI-enabled camera can run advanced video analytics to extract valuable, actionable insights from captured data. By enabling AI functionality in the camera, the AI workloads can be split into camera devices and cloud data centers for operating efficiency, to provide a faster response (less latency) and to reduce bandwidth consumption. For example, in a situation where a security system needs instant response and action after analysing a face or a number plate, sending data to the cloud and waiting for its answer is not feasible.
This is why edge analytics is becoming an area of significant investment for video security systems. It offers low transmission bandwidth consumption as only necessary data is sent to the cloud. Enabling AI at the camera ensures quicker alerts in case of threat detection, allowing faster data-driven analysis and decision-making. Edge-based analytics also come with lower hardware and deployment costs as less on-premises server resources are needed for the security solution.

These AI capabilities become even more essential as large-scale projects such as smart cities are growing and having more advanced functionality. Such trends lead to the development of new applications and AI-enabled camera solutions.
Multi-imager cameras
Multi-imager cameras, sometimes referred to as multi-sensor cameras, typically use multiple camera lenses to offer panoramic video coverage of 180 to 360-degree scenes. Multi-direction overviews combined with artificial intelligence makes them ideal for wide-area coverage applications such as traffic intersections, retail and public spaces.
Capturing up to four independent video streams, each image sensor can be customized using unique video analytic parameters to detect only people and objects of interest per scene while automatically optimizing images. For retail, a loitering detection feature can provide alerts when people linger at a location for longer than usual. Facial recognition matched with watch lists can immediately detect people who may be known as threats.
Automatic number plate recognition (ANPR) cameras
The use of ANPR cameras has risen due to its wide range of applications in traffic management, smart parking, toll automation and intelligent transportation systems in smart cities. For business organisations, cameras with embedded AI-powered ANPR software can automatically recognise license plates and store the metadata in a database for future searches, while comparing them against watch lists to identify whitelisted, blacklisted or suspect vehicles to trigger actions such as opening a barrier gate for access control to restricted sites.
Nowadays, smart cities can integrate ANPR cameras to city sensors for vehicle behavior analysis and traffic optimisation, able to address free flow tolling and real-time road monitoring challenges. Automated parking systems and on-street and off-street ANPR parking solutions decrease the need for gates, tickets and operators and reduce traffic congestion.
From memory and storage point of view, what are the key elements of implementing AI at the camera that manufacturers need to consider?
New video security cameras are now being designed to process multiple video streams and higher resolutions (4K and above) to provide AI algorithms with the large dataset of detailed images and videos required for them to analyse. In addition to this, increasing amounts of metadata are captured and stored on the device to enable operators to quickly search and find relevant video footage. Much of the processing now occurs on the device level. Implementing AI at the camera brings unique challenges as it may have power constraints, performance limits, durability issues and environment impacts. Here are some factors that camera manufacturers should consider while designing their AI-enabled camera.
- Applying low power, high performance memory solutions for data processing
- Utilising high quality, high endurance, application optimised storage solutions for code, application, and data storage
- Ensuring the memory and storage solutions support a wide temperature range for both indoor and outdoor use cases
