IVA 3.5 builds on the features of earlier versions with further enhanced detection possibilities including new color filtering capabilities that allow object color or even a combination of colors to be set as a detection criterion. This is embodied in a "color histogram" function that allows object color or colors, saturation and precision to be set as monitoring criteria. A typical application could be to detect a specific colored vehicle. The filter set features include line crossing alerts, object trajectories and specification filtering. Triggers can be set to transmit alerts if objects cross a pre-defined line or multiple lines, or change speed (running), shape (crouching) or aspect ratio (falling). IVA 3.5 provides support for far infrared (FIR) thermal cameras require different settings to standard color cameras. Content analysis information is generated and stored with the video images. The recorded metadata, comprising simple text strings describing specific image details is much smaller and easier to search through than the recorded video.
