The IVA 3.5 software colour filtering allows object colour or even a combination of colors to be set as the detection criterion.
A ‘colour histogram’ allows object colour or colours to be set as the criteria. A typical application could be to detect a specific colored vehicle.
Filtering triggers can be set to transmit alerts if, for example, objects cross a pre-defined line or multiple lines, or change speed (running), shape (crouching) or aspect ratio (falling).
It also provides support for far infrared (FIR) thermal cameras which require different settings to standard color cameras.
Metadata information is generated and stored with the video images. This comprises simple text describing specific image details and is much smaller and easier to search through than the recorded video.
An optional forensic search license enables users to set up search queries that scan through this recorded metadata and point them to video of interest in a matter of seconds.
“Searches which may take days or even weeks when done manually can be completed within seconds just by searching the metadata with smart search facilities similar to those provided by an Internet search engine”, says Bosch.
Intuitive ‘Object Sampling’ allows the user to capture size, speed, and color in a live scene with a single mouse click on an object. This information is then used as criteria to track similar objects in the future.
Intelligence is embedded in the encoders and cameras themselves. This avoids the single point of failure that can occur in traditional centrally-served systems.
Events are generated at the camera site and only video footage of interest is transmitted to the control center, greatly reducing traffic on the network.
This ‘intelligence at the edge’ or “smart cameras” approach in its IP network video is embedded into all the latest Bosch cameras and encoders, and only a license is required to activate its functions.
