A network camera (also known as an IP camera) functions as a standalone device that captures video, compresses it, and transmits it directly over a network via an Ethernet cable or Wi-Fi. Unlike traditional CCTV systems, these cameras do not require a physical connection to a computer to operate—they act as their own network node with a unique IP address. Core Functionality

Every morning, the camera would power on, automatically receiving its IP address from the router through a system called DHCP. Mr. Henderson liked to think of it as the camera introducing itself to the building’s digital brain. Because it was a wired network camera, it didn't rely on shaky Wi-Fi; instead, a single PoE (Power over Ethernet) cable gave it both its "food" (electricity) and its "voice" (data).

Core Components of a Network Camera

To understand how it works, you must first recognize its key internal components:

Identification: Each camera is assigned a unique IP address to communicate on the network.

1. Image Capture (The Lens & Sensor)

The process begins when light passes through the camera lens and hits an image sensor (either CMOS or CCD). This sensor converts light into an electronic signal. At this stage, the raw image is just a chaotic blob of electrical voltage.
