Fairport, N.Y. – Bosch Security Systems, Inc., a full-line manufacturer of high-quality security solutions, today announced a new version of its Intelligent Video Analysis (IVA) software with easier scene calibration and enhanced forensic capabilities that make it easier for investigators to isolate incidents in recorded video.
IVA 4.0 features a new interactive set up tool that reduces camera calibration time to two minutes per camera and provides immediate feedback to the installer with an on-screen calibration quality traffic light, showing the calibration accuracy by color. Accurately calibrated cameras are more likely to predict the size and speed of any object at various distances, which can be important for filtering out unwanted events and minimizing false alarms.
With the new camera calibration tool, users simply draw measured straight lines and right-angles on the scene, and the tool automatically calculates the perspective. The function enables IVA to make accurate estimates of the size and speed of moving objects.
A new head detection filter further refines IVA’s forensic search function to allow the operator to search for scenes containing human objects. The filter detects human head and shoulder contours to reliably classify people in a scene, significantly reducing the number of ‘false hits’ from factors such as reflections in windows.
IVA 4.0 also comes bundled with FLOW 4.0, a new motion vector algorithm. FLOW 4.0 detects scene activity by the absolute movement of pixels in the scene instead of movement against a ‘learned’ background, which means it works in busy or continuously moving scenes like escalators, rivers and coastlines, roads and crowds. This is particularly helpful in identifying counter-flow, especially in congested scenes where people are moving against a crowd, turnstile misuse, or vehicles traveling in the wrong direction.
With Bosch’s latest Firmware 4.0 release, customers can also switch profiles based on a schedule, such as a day, night or holiday schedule. This is used when the events IVA is configured to detect are different depending on the time of day.
When activated in a Day/Night Bosch Dinion IP or FlexiDome IP camera, IVA 4.0 can also be configured to avoid generating a false alarm during the switch from day (color) to night (monochrome), which is a notorious problem for perimeter surveillance.
Bosch’s AutoDome IP PTZ camera now also runs IVA 4.0, which enables up to 10 IVA configurations running in parallel inside one moving camera, providing full 360-degree coverage.
IVA 4.0 and FLOW 4.0 are included free of charge to existing IVA users upgrading to Firmware 4.0, and can be licensed for Bosch’s IP fixed and AutoDome cameras and video encoders.
