The ViDi Labs calculator helps you calculate the required focal length lens on a camera, or distance to an object, in order to achieve the required pixel density, compliant with various standards. It also helps you calculate the required storage capacity for a given number of recording days.
It consists of two sub-applications, one called Visual and the other Digital.
The Visual sub-application would typically be used by the Surveillance (CCTV) industry installers, integrators and consultants. Many surveillance standards or tenders would specify cameras in a particular location in a project so that facial identification or recognition is achieved at the particular area, like the main door of a building. This is not easily done because such calculation depends on the sensor size, the focal length of the lens and the distance to the object. The ViDi Labs calculator has all the right formulas to do it for you. It also contains a database of all commercially available sensors, from the smallest up to the large format cameras (currently 100MP).
The CCTV industry is not the only field of use, as the ViDi Labs calculator can be used by anybody with a digital camera, be that in photography, cinematography, or machine vision applications, as it can help find the best lens, distance and camera settings for the clearest image.
In the same Visual section, the ViDi Labs calculator also calculates moving object blur as they are recorded with various exposures. Such a calculation is first in the industry and could prove extremely useful in systems used for automatic face recognition, vehicles automatic licence plate reading, reading the roulette wheels winning numbers and all other moving objects that need to be seen more clearly.
Under the Digital sub-application, the ViDi Labs calculator also calculates the recording storage capacity for a given number of cameras, chosen length of recording, percentage of VMD and compression.
User can also enter the type of storage required (RAID type) and the calculator will advise how many hard disks are required to achieve the chosen number of storage days.
For the first time in the surveillance industry, it can also indicate the visual quality of the chosen compression by showing a simulation of the ViDi Labs test chart for the chosen compression (H.264 or JPG).
