Generically, security cameras are computers in a box that have a good camera, a surprising amount of processing power to deal with the video stream, and an evolving level of ability to do inference. Hikvision is/was effectively the leading networked security/surveillance camera manufacturer on the planet for the combination of price and quality, but it seems odd to blame the company for what is a sort of generic tool at this point - maybe a bad analogy, but it would be like blaming Google for Android devices being everywhere.
