    VCA (Video content analysis) is the process of automatically analyzing video images to alarm on predefined events like the detection of moving objects in the monitored area or tampering with the camera. It can also be used to gather statistics about the detected objects.     Depending on the camera type, the following VCA algorithm are available in Bosch cameras: –   Intelligent Video Analytics: Mission-critical, long-distance intrusion detection in extreme weather conditions. Detection and tracking of moving objects. –   Intelligent Video Analytics Flow: Basic motion detection of cells in a grid with velocity and direction. Used for counter flow detection in crowds. –   Essential Video Analytics: Reliable video analytics for small and medium businesses, large retail stores, commercial buildings, and warehouses. Detection and tracking of moving objects. –   MOTION+: Basic change detection of cells in a grid. Can be used to trigger recordings. –   Tamper detection: Detects camera occlusion, turning away from the monitored scene, extreme lighting conditions and basic idle / removed object detection.   If you would like to stop this setting, please follow the steps below.

    The museum mode of Intelligent and Essential Video Analytics is an optimized tracking mode to detect whenever someone tries to reach towards and touch a valuable asset like a museum exhibit. It can also be used in any other application where approaching a sterile zone from a more crowded environment shall be detected.

    Causes   When camera is set to auto track (by web interface) to "auto"-> IVA is detecting an object but camera is not following. Auto tracking works and metadata is displayed only on a stored preposition.   Solution   There was a change introduced starting with FW v.7.70. The new feature is:   i-Track only starts on VCA-Alarm.   You can either program this on presets, e.g a detection field or if you want to have Itrack active regardless of its position, you need to activate "global VCA" and assign task detection area "whole screen" now only activate iTrack "AUXON78" so the eye is in the corner, and your iTrack will always be on sharp   Note: IVA must be active for at least one preset scene in the VCA page on the Settings tab. If IVA is configured for one scene, then all other scenes have Intelligent Tracking enabled by default. If a scene, however, has Motion+ or IVA 5.5 Flow activated, then Intelligent Tracker is disabled for these scenes. Please refer also to the attached document.

    Never lose track of an object of interest! Intelligent Tracking automatically zooms in to and follows a selected Intelligent Video Analytics object as far as possible with the camera. For AUTODOME / MIC IP 7000, this means automatically steering the camera to zoom in to the object and follow it. For a FLEXIDOME IP panoramic 7000, Intelligent Tracking is available in the Virtual PTZ video and steers the dewarped cut-out. For DINION / FLEXIDOME IP 7000 / 8000 cameras, Intelligent Tracking can steer a region of interest (ROI) stream. This article describes how to set Intelligent Tracking up with FW 6.30 and lists the differences based on the camera types.

    In order to start to analyze and optimize Video Analytics settings for particular customer set up, we need initial information and export of example video. This article describes the absolute minimum information we need in order to start analyzing and optimizing Video Analytics performance. Video Analytics (VA) task performance optimization Please provide the following details:   Symptom specific Information   Problem Description   Describe the expected result from the VA task. It is important to get detailed information of the results VA should provide. Define what is the customer’s priority: High sensitivity - miss as few true alarms as possible, but increases the likelihood of more false alarms! High precision – have less false alarms, but accept the risk to miss true alarm! Using VA is always based on balancing between sensitivity and precision. It is not always possible to get high sensitivity and high precision at the same time.   Provide an export of recorded video that should contain: Meta data: for basic understanding of meta data, please read the latest Software Manual Video Content Analytics for instructions about doing a video export with meta data, please read the article: How to export video including meta data (Export video including Video Analytics meta data).   Couple of examples of false alarms (in case false alarms are the issue) Provide the number of false alarms per time span (per day, per week, etc.) What would be acceptable as a number of false alarms per time span   Couple of   examples of situation that should have caused alarm, but VA did not generate the alarm as expected. In this case please provide the time stamp of the event and short description   Screenshot from the Camera Calibration Verification page - only in case calibration is needed for the particular VA functionality  access the Calibration Verification page of the camera (via the Configuration Manager or Web Interface)  provide screenshot from the verification of each parameter used for camera calibration     Note:  For more information on Camera Calibration and Calibration Verification, please check: How To calibrate camera for Video Analytics?

    Upcoming with FW 7.10 and CM 6.20, Camera Trainer is a licensable Intelligent Video Analytics module that allows uses to define objects of intereste and train their own detectors for them based on examples of target objects and non-target objects. In contrast to the moving objects detected in general by IVA 7.10, Camera Trainer allows detection of both moving and non-moving objects, separates and immediately classifies them. Training can be done both on live video as well as on recordings available through the respective camera. The resulting detectors can be down- and uploaded for distribution to other cameras.

    Exporting video with Video Analytics meta data is very useful in the process of optimization of Video Content Analytics performance. One could configure VA, record particular scene and then replay this scene over and over again using different VA configurations. Moreover the video could be exported and replayed multiple times with different VA configuration settings. This article describes the different possibilities - BVMS Operator Client and BVMS Viewer, VRM eXpport Wizard, Web Interface of a Bosch Camera. The choice of the tool depends on the way the camera and recording are managed.

    In many camera systems installed for observation and or security purposes, the camera is used as an information gathering source, providing video streams and I/O alarm facilities as part of the total system. Information, such as scene details in the provided camera’s stream, can be sent to monitoring centers where operators can interpret the relevance of the information. According to his or her human involvement in this case, the follow-up actions for this information for the end-user are manually invoked. In systems where no operators are available, the same camera information can be diagnosed internally; programmed and processed via smart algorithms in the camera and, as a result, IP connections are invoked to follow-up automation by other smart devices on the network.   In this article, you will find such an automation process between Bosch Cameras and Advantech Adam I/O devices. In various Verticals, this Bosch - Advantech combined solution can fully automate adequate follow-up actions for the end-user without the cost of a video management system and human intervention.
