An internal processor converts the raw footage into digital files using codecs like H.264 or H.265.
A network camera, commonly known as an IP (Internet Protocol) camera, is a digital video camera that captures and transmits footage over an Ethernet link or Wi-Fi network. Unlike older analog Closed-Circuit Television (CCTV) systems that require point-to-point coaxial cables, network cameras operate as independent nodes on a local area network (LAN) or the internet. Core Architecture and How It Works
Many IP cameras come with motion detection, facial recognition, and object tracking, which can alert you to specific, actionable events.
: Switch to a more efficient codec like H.265 if supported, which keeps high quality while using less space.
Delivers both operating power and network data through a single RJ45 Ethernet cable.
: Standard entry-level resolution; sufficient for small rooms.
Modern units leverage artificial intelligence and machine learning. They can perform tasks like tripwire detection, license plate recognition, people counting, and differentiating between human movement and blowing trees to prevent false alarms.
IP cameras offer superior, high-definition resolution (1080p, 4K) compared to the limited, standard resolution of many analog cameras.
A "full" camera today must deliver at least 2 Megapixels (1920x1080p). However, a modern pushes into 4K (8 Megapixels) or 12 Megapixels. "Full" resolution means you can perform digital zoom during playback without pixelation—crucial for identifying faces or license plates.
IP cameras transmit data over IP networks (internet or intranet), while CCTV uses coaxial cables. Types of Network Cameras
: The camera needs a unique IP address on your network. Most use DHCP to get one automatically, but static IPs are preferred for stability in professional setups. Storage and Remote Access Options Local Storage
: Triggers instant alerts when an object crosses a digitally drawn boundary in a prohibited direction.
