Video analytics is already a key feature of both indoor and outdoor security systems. That’s why many CCTV cameras have built-in video analytics functions, known as “embedded analytics”. But how effective is in-camera video analysis in protection and alarm triggering? How does it differ from server-based video analytics systems? This article clarifies the main features of in-camera video analytics –edge analytics – and server-based solutions like DFUSION.
Video analytics technology increases the efficiency and accuracy of security systems and reduces security and monitoring personnel’s workload. This applies particularly to artificial intelligence-based systems.
Artificial intelligence (AI) based video analytics solutions identify and track objects and people and recognise and classify different types of activity, giving high levels of protection and security. However, edge analytics does not work in the same way as server-side video analytics. Here are some of the differences: Take note!
The physical installation is the most obvious difference. Server-based systems are external and connect to the CCTV camera for real-time video transmission analysis. In embedded systems, video analysis takes place within the camera. However, the main differences are not merely physical and impact performance, capacity and effectiveness.
Las soluciones server-based proporcionan una mayor potencia de cálculo que tiene lugar en el propio servidor. Los servidores de DFUSION cuentan con una GPU (tarjeta gráfica) dedicada exclusivamente para el vídeo análisis.
El vídeo análisis embebido suele estar integrado en un pequeño chip dentro de la cámara, lo que supone una menor capacidad de procesado y, en consecuencia, son sistemas menos eficaces. Además del riesgo de perder detecciones reales, la analítica de vídeo en cámara puede activar un sinfín de falsas alarmas, inmanejables para los centros de control. ¿Puedes permitirte una NO detección real en tu instalación de seguridad?
Nos centramos ahora en dos conceptos básicos: compatibilidad e integración. Las soluciones basadas en servidor se pueden conectar a cualquier tipo de cámara y fabricante, mientras que los sistemas embedded exigen actualizar y renovar todas las cámaras, lo que conlleva una elevada inversión.
Optar por un sistema de vídeo análisis perimetral basado en servidor es sencillo y rápido, ya que son compatibles con cualquier cámara de seguridad, permitiendo mejorar las instalaciones de forma eficaz sin necesidad de reemplazar las existentes.
En toda instalación de seguridad se recomienda implementar medidas disuasorias integradas a los sistemas de videovigilancia, en este caso, los sistemas de analítica de vídeo server-based de DAVANTIS permiten combinarse fácilmente con cualquier hardware disuasorio mediante relés o integración IP.
Algunas ventajas de un sistema de análisis basado en servidor:
• Mayor potencia de cálculo
• GPU dedicada al vídeo análisis
• Total libertad para utilizar cualquier fabricante de cámaras
• Mejor integración con las CRAs
• Activación de medidas disuasorias mediante relés
• Análisis de transmisiones desde múltiples cámaras
In short, there are still major differences between these systems in terms of accuracy and performance. In-camera video analysis has limitations that reduce its efficiency, while server-based solutions can have custom functions to ensure detection accuracy, even over long distances and in highly complex settings.
In the case of DFUSION, the technology uses a double detection engine that combines appearance and movement, maximising safety even in low visibility and difficult situations (due to the environment or distances).
Another limitation of the in-camera video analytics cameras is their behaviour in case of technical problems. Communication losses, signal outages, and sabotage notifications are commonplace. These incidents must be permanently controlled to have a reliable, image-based perimeter security system you can trust.
So far, many of the installers opting for in-camera video analytics are less than enthusiastic. This is because they are plagued by false alarms, slow, ineffective alert verification, and numerous non-detections that allow burglars to slip through the net. The high rate of false positives, insecurity and high operating costs even persuade clients to do without video analysis in their security systems.
