When installing a video surveillance system, familiarity with various wiring methods is crucial. Here are several key wiring methods:

**Centralized Power Supply Method:** The centralized power supply method is commonly used in the surveillance industry. Common specifications for power cables include RVV2*0.5, RVV2*0.75, RVV2*1.0, and RVV2*1.5. The “2” represents two wire cores, and “1.5” signifies the nominal cross-sectional area of each wire core. In the centralized power supply method, different specifications of power cables may be required based on the number of loads and voltage drop considerations.

**POE (Power over Ethernet) Power Supply Method:** POE power supply has two primary methods: – **Full POE Support:** POE switches directly connect to end devices that support POE via Ethernet cables. – **Partial POE Support:** If the end device doesn’t support POE, you can use a POE injector or splitter.

**Independent Power Supply Method:** This is a basic method where devices are powered using 12V power adapters, commonly known.
**Ethernet Cable Wiring:** Ethernet cable wiring is a commonly used method. Common types include Cat5e, Cat6, and Cat6a cables, each with different electrical characteristics suitable for various environments and requirements.

**Fiber Optic Wiring Method:** For longer transmission distances, consider using fiber optic cabling. Fiber optics transmit signals using light pulses and can achieve stable long-distance transmission.

**Wiring Tips:** Whether indoors or outdoors, using conduit or cable trays can protect the cables. In special environments, such as those with high interference, consider shielded cables. For elevator wiring, use cables designed for elevator use. **In Summary:** Understanding and mastering different wiring methods can help you efficiently install and maintain a video surveillance system. We hope this information is helpful to you.
