: Acts as a central hub for connecting multiple cameras to the network.
A complete network camera setup generally requires the following equipment:
The process of capturing and transmitting video involves several sophisticated internal components:
: An internal microprocessor takes these signals and converts them into a digital format.
: The camera lens focuses light onto an image sensor (typically CMOS or CCD), which converts the light into electrical signals.
: To save bandwidth and storage, the camera uses "codecs" like H.264 or H.265 to compress the high-definition video into smaller data packets.
: Most modern systems use Power over Ethernet (PoE) , allowing a single cable to provide both electricity and data connectivity.
