Artificial Intelligence (AI) has significantly transformed various industries, and security systems are no exception. The integration of AI into security cameras has enhanced their capabilities, making them more efficient and reliable. Let’s explore the progression of AI in security cameras, from traditional motion detection to advanced AI-driven analytics, with examples from leading brands like Hikvision and Verkada.
Traditional Motion Detection
Initially, security cameras relied on basic motion detection. This technology was straightforward: cameras transmitted video signals to a Digital Video Recorder (DVR) or Network Video Recorder (NVR). The recorder processed these signals and identified motion by comparing changes in pixels from one frame to the next. If a significant number of pixels changed, the system would trigger an alarm and start recording.
While effective, this method had its limitations. Early cameras had low resolutions, limiting the ability to zoom in without losing image clarity. Additionally, environmental factors like wind, rain, or moving shadows could trigger false alarms, leading to unnecessary recordings and wasted storage space.
Smart Motion Detection
To address the issues of traditional motion detection, smart motion detection was developed. This technology involved analysing multiple frames to identify motion more accurately. Instead of reacting to every pixel change, smart motion detection focused on significant movements, reducing false alarms and improving efficiency. Key advancements included comparing several frames before and after an event to confirm genuine motion and recording only changes in specific areas of the frame, thus reducing bandwidth and storage usage.
Introduction of AI and Intelligent Analytics
As AI technology progressed, it was integrated into security systems to further enhance motion detection and reduce false alarms. AI-powered systems could distinguish between different types of motion, such as human movement versus environmental changes. Major breakthroughs included training AI algorithms to recognise human shapes and vehicles, triggering alarms only for relevant activities, and understanding human behaviours, such as distinguishing between a person walking normally and someone acting suspiciously.
Edge AI and On-Camera Intelligence
The next step in the evolution was integrating AI directly into cameras. This on-camera intelligence, also known as Edge AI, allowed for real-time analysis and quicker responses. Immediate processing on the camera reduced the time taken to identify and react to incidents, and combining on-camera AI with NVR capabilities improved the accuracy of motion detection and behaviour analysis.
Advanced AI Capabilities
Today, AI in security cameras goes beyond simple motion detection and human recognition. Modern AI systems can perform complex tasks such as facial recognition, identifying specific individuals and triggering alarms if unauthorised persons are detected. They also include number plate recognition to monitor vehicle entries and exits, and active shooter detection to recognise suspicious activities like individuals brandishing weapons and respond accordingly.
Hikvision’s AI Analytics Technologies
Hikvision is a leader in AI analytics, offering a range of advanced features:
- Facial Recognition: This technology recognises faces from a preconfigured list, allowing for the identification of authorised personnel and enhancing access control.
- Vehicle Identification: Hikvision cameras can identify vehicle features, including colour, type, manufacturer, and plate number, improving security and traffic management.
- AcuSense: AcuSense technology distinguishes between humans and vehicles, reducing false alarms caused by other moving objects and enhancing perimeter security.
- Hard Hat Detection: This feature detects whether individuals in critical workplaces, such as construction sites and factories, are wearing hard hats, triggering alarms if safety protocols are not followed.
- People Counting: This provides real-time data on customer flow, helping businesses maintain a friendly environment and improve customer experience.
The Future: Cloud-Based AI and Advanced Analytics
The future of AI in security cameras is moving towards cloud-based solutions. Cloud storage and processing offer several advantages, such as scalability, remote access, and enhanced security. Cloud-based AI systems can leverage powerful servers to perform advanced analytics, providing high-level security features without the need for expensive on-site equipment.
Verkada’s Cloud-Based Solutions
Verkada offers a robust, user-friendly solution with their hybrid cloud cameras. These cameras seamlessly integrate on-site storage with adaptable cloud archiving, ensuring a dependable and scalable option for storing critical footage. Verkada’s cameras feature built-in onboard storage, with some models capable of retaining up to a year of footage. In the event of network disruptions, they continue recording locally, with feeds becoming accessible once connectivity is re-established. Efficient bandwidth usage prioritises conserving network resources by streaming only when actively viewed. Leveraging advanced AI and edge-based processing, Verkada cameras promptly identify and emphasise significant events in real-time, simplifying the extraction of valuable insights from captured footage.
AI Revolutionising the Security Industry
The integration of AI into security cameras has revolutionised the industry, making surveillance systems smarter, more efficient, and more reliable. From basic motion detection to advanced behaviour analysis and cloud-based solutions, AI continues to push the boundaries of what’s possible in security technology. As AI technology evolves, we can expect even more innovative and powerful security solutions in the future.
