What is PoE?

๐Ÿ’ก
Power over Ethernet

PoE transmits both power and data through the same network cable (Cat5e or Cat6). With a PoE switch (โ‚ฌ30โ€“80) and a cable to each camera, you eliminate all separate power cables. One cable does the work of two.

FAQ

Standard Ethernet works correctly up to 100 metres per segment. For more distance, use an intermediate switch or PoE extender.
Depends on camera count and power. For 4 cameras at 15W each, you need a switch with at least 60W total PoE budget. 8-port PoE switches start from โ‚ฌ40โ€“60.
