How to Choose the Correct Power Supply for Your Cctv Camera?

The importance of a power supply for your video security cameras cannot be overstated. Installers and users should use a high-quality CCTV power supply box to ensure the stability and reliability of their video surveillance system. Image distortion, flickering, and even security camera hardware damage can all be caused by a poor power supply. Outdoor security cameras typically use a 12V DC power source, while PTZ cameras use a 24V AC power supply. Some security cameras may use 220V AC power, and inside security cameras commonly use a 5V DC power supply. You’ll learn how to choose the right power source for your security camera in this post.

The most common power supply voltage for security cameras is 12V DC. It isn’t, however, the sole option. Wireless security cameras that are powered by batteries or solar energy are also available.

Inexperienced installers discover that the power capacity is insufficient in real-world installations, necessitating the inclusion of extra power supplies. Because the security camera requires a substantial amount of electricity when it initially turns on, as well as for transmission, calculating the total required power supply does not entail simply adding the rated power of each camera together. The correct way is to multiply the rated power by 1.3 to get the real required power supply for security cameras. You must also account for cable power usage and power budget.

The AC24V power source was chosen since the greater the voltage, the lower the consumption over the same transmission distance. High voltage can provide enough power to the camera. Meanwhile, while debugging security cameras with AC 24V, you can use a sync power supply to sync image vertical frequency across several devices.
