Anomaly Detection and Behavior Recognition

Scylla’s real-time behavioral analysis identifies anomalous events and instantly sends alerts, ensuring maximum security for your facilities.

Scylla Anomaly Detection

How It Works:

● Scylla is optimized to handle multiple video streams on a single GPU, enabling real-time event tracking.
● Upon recognizing an anomalous event based on a series of frames provided to the model, Scylla sends alerts to all designated endpoints.
● The module supports real-time multithreaded processing as well as offline video analysis.
● Models are trained on large datasets of both anomalous and typical video recordings. This enables Scylla to operate effectively across diverse environments and scenarios, providing immediate alerts upon anomaly detection.
● The system continuously self-learns, allowing customization for your specific use case if the current dataset does not fully capture the unique characteristics of your environment.

AI-Based Technologies for Public Safety and Risk Reduction

Robbery Mask Detection

In situations where individuals attempt to conceal their identity during a robbery using masks or balaclavas, traditional surveillance methods may fail to provide timely and accurate threat assessment. The automatic detection technology utilizes advanced algorithms to analyze video streams in real time, identifying the presence of robbery masks or balaclavas.

Anomaly Detection

Foreign Object Debris

Foreign object debris at airports can cause significant damage, costing airlines and airports millions of dollars annually. Such debris can be found near terminal gates, cargo aprons, runways, and other airport locations. It is estimated that FOD-related damages cost the aerospace industry around $4 billion per year, not to mention potential aircraft damage and injuries.

Scylla’s AI-powered object detection can effectively analyze video from high-quality cameras, detect various unattended objects at a distance, and send alerts about possible foreign object debris to all designated endpoints.

Anomaly Detection

Detection of Abandoned Objects

Detection of abandoned objects (AOD) is a critical issue as transportation hubs, critical infrastructure facilities, and law enforcement agencies aim to utilize their video surveillance camera networks to identify unattended bags in public spaces both in real time and for forensic analysis. Abandoned items pose a potential threat to public safety and require immediate attention from police and security personnel.

Scylla’s proprietary object detection algorithms can identify abandoned objects and notify security staff as soon as they are detected. This enables timely action and saves valuable response time.

Anomaly Detection

Trash Detection

Trash in public places, on roads, and at transportation hubs not only poses environmental hazards but can also lead to property damage.
Most of these items are difficult to identify using conventional artificial intelligence. However, Scylla employs robust object detection algorithms that enable it to detect small unattended objects at a distance, even against moving backgrounds.

FAQ

  • Yes, the systems are trained on a wide variety of landscapes and backgrounds, under different lighting conditions and from various angles. Essentially, the solution is quite resilient to background variations — as long as the object of interest is visible, the system will reliably detect it.

  • The answer depends on several factors, primarily the camera’s characteristics, especially its resolution. Resolution initially plays a major role; however, Scylla’s built-in scaling and tracking algorithm allows the system to analyze the object at the camera’s original resolution. Unlike similar AI-based security solutions, Scylla is less dependent on the visual image quality, which typically degrades when processed through neural network platforms.

    There are a number of factors related to the camera’s "image quality," such as stream bandwidth, encoding, etc. Visibility conditions—like lighting, object orientation (see question 6 regarding object angle), and pixel size of the object—also need to be considered. The latter depends linearly on the distance from the camera and can be used to estimate the maximum detection range.

    For example, a reliable minimum object size for firearms detection is about ~15-17 pixels, which corresponds to a maximum distance of approximately 10-12 meters for most HD cameras.

  • Detection typically occurs within the first 400 ms (in some cases, up to 2 seconds). When evaluating response time, keep in mind that most IP cameras used today introduce some sub-second video stream latency. Additionally, in cases where Scylla is deployed in the cloud, you should consider the time delay caused by the stream reaching the cloud and the response being delivered to the dashboard.

  • The Scylla Object Detection System is designed to support security units in their daily operations by enhancing their capabilities and eliminating potential shortcomings related to human error. Additionally, in the event of a potential threat, the alerts generated by Scylla are enriched with critical information that enables rapid and comprehensive on-site threat analysis and effective planning of countermeasures.

  • The system is based on computer vision algorithms, and threat detection relies on visual content analysis. This means that to detect a weapon inside a bag, Scylla must be connected to X-ray or millimeter-wave scanners. When operating on surveillance cameras that work solely in the visual spectrum, the Scylla Object Detection System can only detect visible, unconcealed weapons.

  • No, the system is trained to recognize objects from all possible angles. However, in certain specific cases, the angle of the object may influence detection accuracy, as the features Scylla uses to classify an object can be more distinct from some angles than others. For example, if a gun or rifle is held at an angle to the camera, it may reveal more distinguishable features compared to when it is pointed directly at the camera.

  • An alert containing all relevant information is generated and sent to the end users responsible for security. There are several configurable notification channels, including the Scylla Dashboard, the Scylla mobile app, access point relay boards, and VMS alert APIs, among others.

  • Yes, all Scylla solutions can be deployed both in the cloud and on-premises. Moreover, Scylla's AI-powered software solutions are cloud-provider agnostic, as long as the cloud instance runs on Linux and is equipped with an Nvidia GPU.

  • Yes, it can. The maximum detection range of the Scylla Object Detection Solution depends on the specifications of the camera, such as contrast ratio, pixel crosstalk, and other factors. However, in general, the solution complies with standard industry DRI requirements—meaning the identification threshold (the distance at which the class of an object can be determined) is approximately 20 pixels for small arms.

  • An alarm is classified as true when the AI’s prediction aligns with reality (i.e., the object of interest is correctly identified, or the intended action is accurately detected). A false alarm occurs when an alert is triggered incorrectly. Unfortunately, due to the probabilistic nature of AI, false alarms are largely unavoidable. However, thanks to the advanced artificial intelligence and machine learning powering the Scylla Object Detection System, it meets any industrial-grade standard. Moreover, Scylla AI’s video analytics modules are continuously improved through retraining on past errors, further reducing the number of false positives over time.

  • Most questions regarding camera limitations and requirements can be answered with a simplified “empirical” rule: if a person can see and identify an object of interest, then the Scylla AI video analytics system will also be able to do so (and in some cases even surpass a person thanks to built-in scaling and re-checking algorithms). As for the minimum camera parameters, they depend on each specific use case and the object you are trying to detect. Of course, the camera must have a digital output or, at least, be connected to a video recorder that has one. The Scylla object detection system can accept virtually all types of streams, such as RTSP/RTMP, HTTP, etc. Typically, the minimum required resolution starts at HD (1280x720) and 5 FPS. The parameters that determine frame/image quality vary from camera to camera, but we recommend paying attention to characteristics such as bandwidth, encoding, and sharpness, and improving them if necessary.

  • Absolutely. Scylla does not store any information unless explicitly requested by the user.

  • The Scylla Object Detection System is designed to function effectively in challenging environments where cameras with built-in algorithms may fail to perform properly. The AI engine compensates for limitations caused by difficult conditions, including poor lighting, slightly distorted frames, environmental factors, and weather effects.
