What shocked me when I saw Elite for the first time, is the huge number of star systems with their own names, population size and descriptions. I knew there was no way such volume of data in the tiny executable file.
Thank you for mentioning Wasniak book!
I really enjoyed iWas.
Another great book is “Fire in the Valley: The Making of The Personal Computer” (Second Edition) 2nd Edition
by Paul Freiberger (Author), Michael Swaine (Author)
And I like as well a book from Merrill Chapman. “In search of stupidity: Over Twenty Years of High Tech Marketing Disasters”.
There are IP cameras with a microSD card slot. A memory card allows you to store the archive directly on the camera itself or duplicate the recording if a failure occurs in the local network. Simultaneously, many Video Management Systems , in the event of a loss of connection, can copy the missing archive from the camera memory card after restoring the network connection.
In some countries, for some types of buildings, the archive depth can be regulated by law. These can be buildings with a requirement for anti-terrorist measures, for instance, including sports facilities, facilities with a mass presence of people, and railway striations / airports.
We created a free web based calculator to estimate video archive storage space for your video surveillance system or simply for 1 camera you installed.
The calculator also estimates required network bandwidth for IP cameras.
It is a web app (Javascript+React) that runs in a browser or on a tablet or a smartphone.
Presently, the most common compression codecs are H.264 and H.265 . Their advantage is a high level of video compression, which saves space in the video archive. Motion JPEG compression is also supported.
And here is a manual for the calculator https://www.jvsg.com/cctv-storage-calculator/
