For security professionals who thought analog systems were a thing of the past, a new approach by Mythic Inc. demonstrates that everything old is new again.

Using older technology in a new way, the Mythic M1076 Analog Matrix Processor leverages analog computer chips from a previous generation to drive new levels of artificial intelligence (AI) performance with lower power requirements. 

Low power and high speed 

Mythic provides power-efficient AI at the edge, including inside video cameras. The design combines embedded flash memory with analog computing power to achieve faster AI processing, supporting up to 25 trillion operations per second (TOPS), with the very-low power levels conducive to edge devices.

The scalable, single-chip analog compute-in-memory architecture provides high-performance inference without consuming the power and energy that digital solutions require to move data at high speeds between separate processing and storage components.

Single-chip design 

High-resolution video analytics with low latency, comparable to a GPU, is provided by AI, but at 10 times less power

We use a different approach to processing and storage by resurrecting analog technology for faster computing power in a limited size and cost,” says Tim Vehling, Senior Vice President, Product and Business Development at Mythic. The Mythic chip solves several design challenges for camera manufacturers.

The single-chip design with no DRAM (dynamic random-access memory) caters to limited space requirements. High-resolution video analytics with low latency, comparable to a graphics processing unit (GPU), is provided by AI, but at 10 times less power than a typical system on chip (SoC) or GPU. The typical 3-4-watt power draw is consistent with a limited power budget for power over Ethernet (PoE). Passive heat dissipation does not require active thermal management.

Applications of the analog chip

For video applications, the chip provides faster speed to accommodate more cameras, more resolution, and more details in images. In addition to providing scalability, the chip supports a variety of host platforms, including X86, NVIDIA Jetson Xavier NX/TX2, Qualcomm RB5, and NXP i.MX8M. It supports Linux Ubuntu 18.04 and Linus for Tegra (NVIDIA) operating systems.

The chips can plug into NVIDIA or Qualcomm platforms to enhance AI capabilities for a variety of applications. The chip also has utility in other deployments, including drones, where Mythic works with the Qualcomm RBS platform to enable multi-thousand-dollar drones for larger applications.

Integration into devices

The chip can augment the capabilities of a CPU without replacing it or completely redesigning a product

The chip handles image sensing, multiple cameras, radar, and lidar sensors, in addition to flight navigation, control, and communication, in addition to in-flight analytics. Inside NVRs, Mythic chips provide high-level processing at a fraction of the cost, says Vehling.

Integration of the technology into cameras and other products is simple – it simply plugs into an M.2 expansion slot, and the software is downloaded to drive the AI algorithms. The chip can augment the capabilities of a CPU without replacing it or completely redesigning a product, in effect providing an instantaneous improvement in performance.

No shortage

Because Mythic uses older technology, there are no shortages compared to some later-generation chips. The 40-nanometer chips are a mature technology, manufactured in Japan, while newer processors are smaller at 5 or 7 nanometers. The newer chips are more likely to be in short supply.

The Mythic M1076 chip is currently being evaluated but is not yet in production. The company expects to be shipping the product in the second half of 2022, and it will be sold to camera manufacturers and other OEMs to be incorporated into their products. 

Adds value inside cameras

For security end-users, Mythic’s AI chips will add new value inside video cameras and other equipment in terms of better performance, small size, and less power.

For integrators, the technology will expand equipment options, such as providing high-level analytics in cameras while requiring only 2 to 3 watts of power, consistent with the use of PoE.

How Should End Users Measure The ROI Of Security Systems?
How Should End Users Measure The ROI Of Security Systems?

Traditionally, security has been seen as a cost center rather than as a profit center or a source of revenue in an organization. Therefore, end-user security managers have struggled to cost-justify their purchases of security systems: How can you assign value to preventing a catastrophic loss unless or until such a loss happens (which you’re trying to avoid!). Even so, security’s return on investment (ROI) picture is changing, with expanded system capabilities and technologies that provide benefits beyond the traditional security function. For the latest, we asked this week’s Expert Panel Roundtable: How should end users measure the return on investment (ROI) of security systems? 

Top 10 Articles Of 2021 Reflect A Changing Security Marketplace
Top 10 Articles Of 2021 Reflect A Changing Security Marketplace

Our most popular articles in 2021 provide a good reflection of the state of the industry. Taken together, the Top 10 Articles of 2021, as measured by reader clicks, cover big subjects such as smart cities and cybersecurity. They address new innovations in video surveillance, including systems that are smarter and more connected, and a new generation of computer chips that improve capabilities at the edge. A recurring theme in 2021 is cybersecurity's impact on physical security, embodied by a high-profile hack of 150,000 cameras and an incident at a Florida water plant. There is also an ongoing backlash against facial recognition technology, despite promising technology trends. Cross-Agency collaboration Our top articles also touch on subjects that have received less exposure, including use of artificial intelligence (AI) for fraud detection, and the problem of cable theft in South Africa. Here is a review of the Top 10 Articles of 2021, based on reader clicks, including links to the original content: Smart cities have come a long way in the last few decades, but to truly make a smart city safe Safety in Smart Cities: How Video Surveillance Keeps Security Front and Center The main foundations that underpin smart cities are 5G, Artificial Intelligence (AI), and the Internet of Things (IoT) and the Cloud. Each is equally important, and together, these technologies enable city officials to gather and analyze more detailed insights than ever before. For public safety in particular, having IoT and cloud systems in place will be one of the biggest factors to improving the quality of life for citizens. Smart cities have come a long way in the last few decades, but to truly make a smart city safe, real-time situational awareness and cross-agency collaboration are key areas that must be developed as a priority. Fraud detection technology How AI is Revolutionising Fraud Detection Fraud detection technology has advanced rapidly over the years and made it easier for security professionals to detect and prevent fraud. Artificial Intelligence (AI) is revolutionizing fraud detection. Banks can use AI software to gain an overview of a customer’s spending habits online. Having this level of insight allows an anomaly detection system to determine whether a transaction is normal or not. Suspicious transactions can be flagged for further investigation and verified by the customer. If the transaction is not fraudulent, then the information can be put into the anomaly detection system to learn more about the customer’s spending behavior online. For decades, cable theft has caused disruption to infrastructure across South Africa Remote Monitoring Technology: Tackling South Africa’s Cable Theft Problem For decades, cable theft has caused disruption to infrastructure across South Africa, and it’s an issue that permeates the whole supply chain. In November 2020, Nasdaq reported that, “When South Africa shut large parts of its economy and transport network during its COVID-19 lockdown, organized, sometimes armed, gangs moved into its crumbling stations to steal the valuable copper from the lines. Now, more than two months after that lockdown ended, the commuter rail system, relied on by millions of commuters, is barely operational.” Physical security consequences Hack of 150,000 Verkada Cameras: It Could Have Been Worse When 150,000 video surveillance cameras get hacked, it’s big news. The target of the hack was Silicon Valley startup Verkada, which has collected a massive trove of security-camera data from its 150,000 surveillance cameras inside hospitals, companies, police departments, prisons and schools. The data breach was accomplished by an international hacker collective and was first reported by Bloomberg. Water Plant Attack Emphasises Cyber’s Impact on Physical Security At an Oldsmar, Fla., water treatment facility on Feb. 5, an operator watched a computer screen as someone remotely accessed the system monitoring the water supply and increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million. The chemical, also known as lye, is used in small concentrations to control acidity in the water. The incident is the latest example of how cybersecurity attacks can translate into real-world, physical security consequences – even deadly ones. Video surveillance technologies Organizations around the globe embraced video surveillance technologies to manage social distancing Video Surveillance is Getting Smarter and More Connected The global pandemic has triggered considerable innovation and change in the video surveillance sector. Last year, organizations around the globe embraced video surveillance technologies to manage social distancing, monitor occupancy levels in internal and external settings, and enhance their return-to-work processes. Forced to reimagine nearly every facet of their operations for a new post-COVID reality, companies were quick to seize on the possibilities offered by today’s next-generation video surveillance systems. The Post-Pandemic Mandate for Entertainment Venues: Digitally Transform Security Guards At sporting venues, a disturbing new trend has hit the headlines — poor fan behavior. At the same time, security directors are reporting a chronic security guard shortage. Combining surveillance video with AI-based advanced analytics can automatically identify fan disturbances or other operational issues, and notify guards in real time, eliminating the need to have large numbers of guards monitoring video feeds and patrons. The business benefits of digitally transformed guards are compelling. Important emerging technology Why Access Control Is Important In a workspace, access control is particularly crucial in tracking the movement of employees should an incident occur, as well as making the life of your team much easier in allowing them to move between spaces without security personnel and site managers present. It can also reduce the outgoings of a business by reducing the need for security individuals to be hired and paid to remain on site. The city of Baltimore has banned the use of facial recognition systems by residents Baltimore Is the Latest U.S. City to Target Facial Recognition Technology The city of Baltimore has banned the use of facial recognition systems by residents, businesses and the city government (except for police). The criminalization in a major U.S. city of an important emerging technology in the physical security industry is an extreme example of the continuing backlash against facial recognition throughout the United States. Several localities – from Portland, Oregon, to San Francisco, from Oakland, California, to Boston – have moved to limit use of the technology, and privacy groups have even proposed a national moratorium on use of facial recognition. Powerful artificial intelligence Next Wave of SoCs Will Turbocharge Camera Capabilities at The Edge A new generation of video cameras is poised to boost capabilities dramatically at the edge of the IP network, including more powerful artificial intelligence (AI) and higher resolutions, and paving the way for new applications that would have previously been too expensive or complex. Technologies at the heart of the coming new generation of video cameras are Ambarella’s newest systems on chips (SoCs). Ambarella’s CV5S and CV52S product families are bringing a new level of on-camera AI performance and integration to multi-imager and single-imager IP cameras.
