TCP/IP is often a conceptual design that implies the following four practical levels for these communication backlinks:
In recent times, using entire body-worn video cameras has been launched for numerous employs. As an example, as a brand new method of surveillance in legislation enforcement, you'll find surveillance cameras which can be worn because of the police officer and are frequently Situated on a police officer's chest or head.
