Introduction

Effective power supply methods are crucial considerations in video surveillance projects. Selecting the right power supply approach ensures optimal monitoring outcomes and cost-efficiency. In the realm of video surveillance, various power supply methods exist, each with its unique advantages and considerations. OHWOAI, a leader in surveillance solutions, sheds light on these methods and their implications for achieving enhanced monitoring efficiency.

Understanding Power Supply Methods

1. **Centralized Power Supply:**

   Centralized power supply involves installing power source equipment in power and battery rooms, distributing power to communication devices through unified transformation.

   Advantages: Simplified control, reduced cable usage, and improved aesthetics.

   Considerations: The total capacity of centralized power supply equipment must exceed the combined capacity of downstream loads. Cable diameters should also fulfill the current requirements of downstream loads.

2. **Point-to-Point Power Supply:**

   Point-to-point power supply entails running 220V AC power directly from the control room to individual cameras, connecting each camera with a dedicated DC 12V power supply.

   Advantages: Low voltage loss during AC power transmission and strong resistance to interference.

   Considerations: This approach demands installing a power supply for each camera, potentially adding complexity to installation.

3. **Power over Ethernet (PoE):**

   PoE technology delivers DC power over existing Cat.5 Ethernet cabling, providing power to devices without altering the cabling infrastructure. Widely used in high-definition digital surveillance systems.

   Advantages: Cost-effective, flexible deployment, and a single port can deliver up to 30W of power.

   Considerations: Requires high-quality network cables and has distance limitations.

4. **Important Considerations:**

   For infrared cameras, centralized power supply might not be suitable as the high current draw during infrared operation can affect all cameras' infrared performance.

   Point-to-point power supply can lead to efficient cable usage but may pose challenges in maintenance and repair.

   Centralized power supply simplifies maintenance and reduces the likelihood of problems arising, but it may not be as cost-effective in terms of cable usage.

   When numerous cameras are involved within a 100-meter distance, PoE is recommended. It's convenient, efficient, and requires minimal special construction, although proper PoE equipment selection is essential.
