ViDiLabs Calc บน Windows PC

1. The ViDi Labs calculator helps you calculate the required focal length lens on a camera, or suggested distance to an object, in order to achieve the required pixel density (read clarity), compliant with various standards.

2. 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.

3. In the Pixel Density area of the pre-set buttons on the right hand-side we introduced the correct pixel densities for Face Identification (FI), Recognition (FR) and Inspection, as per the Australian Standard corrigendum document for the IEC 62676-4: 2015.

4. Such calculations are 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.

5. To comply with such tenders is not easy because pixel density calculation depends on the sensor size, the focal length of the lens and the distance to the object, all interdependent.

6. It also helps you calculate the required storage capacity for a given number of recording days or minutes (in case you need to export an incident on a USB flash drive).

7. 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).

8. Users 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.

9. The CCTV industry is not the only field of use for the ViDiLabs calculator, because this app can be used by anybody with a digital camera, be that in photography, cinematography, or in machine vision, as it can help find the best lens, distance and camera settings for the clearest image.

10. In addition to the "facial" pixel densities pre-set buttons, we have also introduced pixel densities pre-sets for common projects such as Licence Plates Recognition (LPR), money and playing cards.

11. With the latest version 2.0 of this app we have introduced manual entry of any of the variables (by double-tapping a window), including distances or focal length that are not in the scrolling picker data-base, or perhaps you use an "unusual" or new sensor size.
