It is important to mention that in my work I deal with two different types of webcams. In the first and second chapters, I deal with the security aspects of separate webcams, which from the place where they are located, automatically transmit to the network or to the recording device. The third and fourth part then deals with webcams, which are accessories of a fixed computer or are built into laptops and mobile phones and are used by users mainly for video conferencing calls.As far as the legislation in the Czech Republic is concerned, as far as cameras are concerned, it is not completely clear, concise and sufficiently detailed, therefore the first part of the work aims to summarize together the available information and point out the basic rules by which everyone should operate. system on its private land or public space is considering managing.
