12 Volt 2 Amp Switchmode CCTV Power Supply

Ideal replacement power supply for Swann analogue CCTV cameras

Model: SR-PSU-12V2A-4S

If your CCTV cameras have stopped working, are flickering, dropping out, or your system is having intermittent issues, the power supply may be the cause. This 12V 2A switchmode CCTV power supply is designed for analogue CCTV cameras and includes a 4-way splitter, making it a convenient option for replacing a faulty adapter or powering multiple compatible cameras from one supply.

Key Features

12V DC Output

Provides stable 12V DC power for compatible analogue CCTV cameras.

2 Amp Capacity

Supplies up to 2000mA / 2A total output across connected cameras.

4-Way Splitter Included

Power up to 4 compatible analogue cameras, provided the total current draw stays within 2A.

2.1mm Centre Positive Plug

Common CCTV power connector used on many analogue security camera systems.

Understanding Power Requirements

This power supply provides 12V DC at 2 Amps, which means it can safely supply up to 2000mA in total. Each camera may use a different amount of power, commonly around 200mA to 500mA, depending on the model, infrared night vision and camera type.

For example, if you connect 4 cameras that each use around 400mA, the total draw is 1600mA / 1.6A, which is within the 2A limit. If too many cameras are connected, or if the cameras require more current than expected, the power supply may become overloaded and cause camera dropouts, flickering, shutdowns or unstable video.

How to Check Your System: DVR or NVR?

This power supply is designed for analogue CCTV systems that use a DVR. It is not normally used for IP camera systems that run through an NVR.

System Type	How to Identify It
DVR / Analogue CCTV	Uses coaxial camera cables, often with a separate power connector. This is the type of system this power supply is intended for.
NVR / IP CCTV	Uses Ethernet/network cables for IP cameras. These systems often use PoE and may not be compatible with this 12V power supply.

Keep Your CCTV System Running Smoothly

A failing or underpowered CCTV power adapter can cause frustrating problems such as camera flickering, black screens, unstable video, random dropouts or cameras only working during the day. Replacing the adapter with a suitable 12V 2A CCTV power supply can help restore stable operation to compatible analogue camera systems.

Before connecting multiple cameras, always check the total power draw and make sure it does not exceed 2000mA / 2A. Staying within the safe operating limit helps prevent overloads and keeps your cameras running reliably.

Need a replacement CCTV power supply? This 12V 2A adapter with 4-way splitter is a simple solution for many Swann analogue CCTV camera systems and compatible 12V analogue cameras.
