Power Supplies
Dedicated power supplies convert building AC power into the regulated DC voltages that security cameras, access control locks, and other low-voltage devices require. Properly sized and installed power supplies prevent the voltage drops, noise, and overloading that cause unreliable device behavior.

Frequently Asked Questions
Why not just use PoE for everything?
PoE works well for cameras and access points, but door locks, magnetic locks, and some legacy devices require separate DC power. Access control systems typically need dedicated power supplies for lock hardware.
