In today's security-conscious world, closed-circuit television (CCTV) systems have become essential for homes, businesses, and public spaces. However, the functionality of these surveillance systems heavily depends on a stable and reliable power supply. One of the most efficient ways to power multiple CCTV cameras simultaneously is through a 4 Channel Switched-Mode Power Supply (SMPS). In this guide, we delve into everything you need to know about 4 channel SMPS units, with a focus on their performance, advantages, disadvantages, and the best online platforms to purchase them.
What is a 4 Channel SMPS for CCTV?
A 4 Channel SMPS (Switched-Mode Power Supply) is a compact and efficient device designed to power up to four CCTV cameras simultaneously. It converts high-voltage AC input into regulated low-voltage DC output, typically 12V, which is ideal for most surveillance cameras, including dome, bullet, and infrared models. The "4 channel" term indicates that it can independently supply power to four cameras, reducing the need for multiple adapters and minimizing clutter in your setup.
Key Features of 4 Channel SMPS
- Output Voltage: Generally 12V DC, suitable for most CCTV cameras.
- Current Output: Typically ranges from 4A to 5A, evenly distributed across four outputs.
- Protection Mechanisms: Includes over-voltage, over-current, short-circuit, and surge protection.
