Charger for CCTV, Access Control

A reliable charger and power supply for CCTV and access control systems is the foundation of 24/7 security. Whether you need a standard 12V 2A adapter for a single IR dome camera or a heavy-duty 240W supply for a multi-door magnetic lock system, we have the exact specifications you need. Backed by 20 years of engineering experience in Sham Shui Po, our technical team provides on-site voltage testing and load capacity advice to ensure your surveillance network never experiences downtime.

Security Power Supply Specifications & Architecture

Selecting the correct power adapter ensures your security equipment operates efficiently and prevents premature hardware failure. Here is a technical breakdown of our core power solutions:

Power Supply Type Key Specifications Best Use Case
Standard 12V Adapters 12V 1A - 2A, 5.5x2.1mm DC Plug Individual analog/IP cameras, standalone RFID keypads, and DVRs.
High-Amperage Adapters 12V 5A - 10A, 5.5x2.5mm / Terminal Block 4 to 8-channel DVR setups and multi-camera power splitters.
Industrial Switching Power Up to 240W, Screw Terminal Connections Magnetic locks (Maglocks), electric strikes, and enterprise access control panels.

Important Note (Voltage Drop Limitation): When powering CCTV cameras over long distances (e.g., over 30 meters) using standard DC splitters and thin cables, you will experience a severe "voltage drop." A 12V adapter might only deliver 10V at the end of the cable, causing the camera's IR night vision to fail or flicker. For long cable runs, you must use a centralized power distribution box with an adjustable voltage output (tuning up to 13.5V) or switch to a PoE (Power over Ethernet) architecture.

Frequently Asked Questions (FAQ)

Q: Can I use a spare 12V 1A router adapter for my outdoor CCTV camera?
A: While it may power the camera during the day, it will likely fail at night. When a CCTV camera's Infrared (IR) LEDs turn on for night vision, the power draw spikes significantly. If the adapter lacks sufficient amperage, the camera will enter a continuous reboot loop. We strongly recommend using at least a 12V 2A adapter for any IR-equipped security camera.

Q: Why does my magnetic door lock get extremely hot?
A: Magnetic locks (Maglocks) draw continuous current to stay locked (Fail-Safe design). If you are using a cheap, unregulated power adapter, voltage fluctuations will cause the lock's internal copper coils to overheat, significantly reducing its lifespan. Always use a high-quality, regulated industrial power supply for access control systems.
