12V Access Control Power Supply for Intercom and Electric Lock Systems

A dedicated 12V DC power supply for buyers building a proper wired intercom or access-control setup rather than stopping at a screen and doorbell alone.

• Works with: compatible 12V DC electric strikes, access-control modules, RFID/keypad controllers, and wired entry-system accessories that specify 12V DC input.
• Does not work with: USB-powered devices, PoE cameras, 24V AC doorbells, battery doorbells, or mains-powered lighting.
• What else you may need: an electric strike or maglock, exit button, access controller or intercom relay, suitable low-voltage cable, and a qualified installer for door hardware.
• Choose this if: your access-control path clearly calls for 12V DC and you want a cleaner matched supply instead of improvising with random adapters.

Honest install note: This is not a universal smart-doorbell accessory. Match voltage, current draw, polarity, wiring route, and lock type before ordering.
