How does a hidden camera with cellular connectivity work?

A hidden camera with cellular connectivity is a surveillance device that is designed to transmit audio and video signals to a remote location via cellular network. It is equipped with a cellular modem that allows it to connect to the internet and send data through the cellular network. The camera captures audio and video footage and transmits it to a cloud-based server or directly to a smartphone, tablet, or computer using a designated app. This enables the user to remotely access the live footage from anywhere in the world, as long as there is an internet connection.
