Why PoE Budgets Fail

Power over Ethernet (PoE) follows strict standards like 802.3af (15.4W) and 802.3at (30W). However, many engineers make the mistake of adding up the *advertised* consumption without considering line loss.

Voltage Drop: In a 100-meter copper run, several watts can be lost as heat. If your switch is running at 95% capacity, a single high-definition camera starting its "Night Vision" IR sensors could pull enough extra current to reboot the entire switch.
