Power
Reliable power delivery is what separates a security system that works continuously from one that drops cameras during storms, loses access control during outages, and degrades over time from electrical noise. Every component in a security system — cameras, controllers, recorders, switches, intercoms — needs clean, stable, protected power. This section covers the power infrastructure components we commonly include in Chicago-area installations..

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..
UPS
Uninterruptible Power Supplies (UPS) provide battery backup and power conditioning for critical security infrastructure. When the building power goes out, the UPS keeps your recorders recording, your access control doors functioning correctly, and your network switches online.
PoE Injectors
PoE injectors add Power over Ethernet capability to network connections where the upstream switch does not provide PoE. They are commonly used to power individual cameras, access points, or intercom stations at remote locations or in retrofit installations where replacing the switch is not practical..
Surge Protection
Surge protectors guard sensitive security equipment against voltage spikes from lightning strikes, utility switching, and electrical noise. Cameras mounted outdoors, equipment in buildings with older electrical systems, and devices connected to long cable runs are particularly vulnerable.
