: Cameras connect via Wi-Fi or a physical Ethernet cable . Many support Power over Ethernet ( PoE ), which provides both power and data through a single cable. Access and Configuration
Generally easier to install than analog systems, though initial network configuration (finding the IP address) is required. network camera networkcamera work
Network cameras use codecs (compression-decompression algorithms) such as: : Cameras connect via Wi-Fi or a physical Ethernet cable
Every morning, the camera would , 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). Because it was a wired network camera ,
Plug the camera into the PoE switch. The camera powers on, performs a self-test (pan/tilt if PTZ model), and requests an IP address from the router.
