With Bosch Intelligent Video Analysis, the system analyzes video content based on your input criteria. These are entered via the ‘rule wizard’, which takes you through the process step-by-step. Areas to watch within each view, object size and shape, motion direction and many more parameters can be set for each camera. The intuitive menu makes set-up straightforward and allows you to specify what event, or combination of events, will trigger an alarm.
Any events detected by the system that fit the pre-defined criteria are depicted clearly on-screen. Object outlines, color-coded according to the alarm status, overlay the monitor images to show their position. Factors such as aspect ratio and perspective are automatically accounted for.
Extra reliability
To help ensure alarms are only triggered for real events, features such as camera calibration and perspective correction greatly enhance Intelligent Video Analysis accuracy and reliability. Also, special filters for size, speed, direction and aspect ratio minimize false alarm rates.
Statistical analysis of the captured images makes the system highly weather resilient. It can filter out rain or even snow. Image stabilization ensures that only movement within the captured areas is detected, and not movement caused by the camera swaying in the wind.
Guarding against physical interference, Intelligent Video Analysis also features tamper protection that highlights any sudden changes to the input signal compared with a reference frame.
