CCTV Power Supply Calculator
CCTV cameras draw significantly more power at night when Infrared (IR) night-vision LEDs activate. Calculate total system load and size your central 12V DC power distribution box correctly.
Camera & Hardware Inventory
Provides 25%+ continuous headroom for peak night-time IR surge.
Many DIY security installations work perfectly in daylight, but as soon as the sun sets and all IR night-vision LEDs click on simultaneously, the power supply sags below 10.5V. The cameras enter endless reboot loops until dawn! Always size for Night Peak.
