For video surveillance setups, the types of cables and connectors required depend on the type of system being used, such as analog, digital, or IP-based systems. 1. **Analog Systems:** - **Coaxial Cable (RG59/RG6):** Used to transmit video signals from analog cameras to DVRs. RG59 is common for short distances, while RG6 is used for longer runs. - **BNC Connectors:** These are used to connect coaxial cables to cameras and DVRs. They provide a secure connection for video signals. - **Power Cables:** Separate cables are often needed to supply power to the cameras, typically using 18/2 gauge wire. 2. **Digital Systems (HD over Coax):** - **Coaxial Cable (RG59/RG6):** Similar to analog systems but used for transmitting HD video signals. - **BNC Connectors:** Used for connecting HD cameras to DVRs. - **Power Cables:** As with analog systems, separate power cables are required. 3. **IP-Based Systems:** - **Ethernet Cable (Cat5e/Cat6):** Used for transmitting video, audio, and power (via PoE) from IP cameras to NVRs or network switches. Cat6 is preferred for higher data rates and longer distances. - **RJ45 Connectors:** These are used to terminate Ethernet cables and connect them to cameras, NVRs, and network equipment. - **PoE (Power over Ethernet) Switches/Injectors:** These provide power to IP cameras over Ethernet cables, eliminating the need for separate power cables. 4. **Fiber Optic Systems:** - **Fiber Optic Cable:** Used for long-distance transmission of video signals, especially in large-scale installations. - **Fiber Optic Connectors (SC/LC):** These are used to connect fiber optic cables to network equipment. 5. **Additional Components:** - **Baluns:** Used to convert video signals for transmission over twisted pair cables like Cat5e/Cat6 in analog systems. - **Adapters and Splitters:** Used for connecting multiple devices or converting between different types of connectors.
