Unlike analog systems, network cameras offer advanced capabilities precisely because they "speak" data:
Most professional network cameras utilize via an RJ45 Ethernet port. Guided by IEEE standards (802.3af, 802.3at, or 802.3bt), PoE allows a single Cat5e or Cat6 cable to deliver both low-voltage electrical power and high-speed data transmission simultaneously. This eliminates the need for localized AC outlets at every camera installation site. Network Protocol Stack

Many modern consumer and enterprise systems stream encrypted video directly to cloud servers, eliminating the need for on-site recording hardware.

Because they have their own IP addresses, you can view live feeds from anywhere using a smartphone or PC. Key Features and Capabilities
Finally, the packets are sent out through the network camera’s Ethernet port (using PoE – Power over Ethernet) or its built-in Wi-Fi radio. They travel through switches, routers, and possibly the internet to reach a client: a video management system (VMS), a web browser, a NAS drive, or a mobile app.
Once the light passes through the lens, it hits an electronic image sensor. This sensor is covered in millions of light-sensitive sites called pixels.
Network cameras are easy to add to an existing network without extensive rewiring. Types of Network Cameras
