Up until now, you needed an expert to decode security camera recordings, but now it can be done with artificial intelligence. On one hand, automation will simplify the work, but, on the other hand, it can contribute to violation of citizens' privacy.
So far, surveillance technologies cannot immediately identify a person, even with a database, but it's just a matter of time. Such developments exist even now, for example, Ella system by the IC Realtime. The platform analyzes everything that it gets from surveillance cameras, and collects information in a huge base. Ella is really useful because it is able to find a person by the description of clothing or vehicle model.
The basis of the system is Google Cloud, which allows processing information from just one camera or from thousands. You can use this service by purchasing a subscription. The cost is determined by the number of cameras. The minimum payment per month is $7.
