The "Di CCTV Cable Outdoor 3+1" typically refers to an outdoor-rated CCTV cable that includes three video channels and one power channel. Here's a breakdown of what this cable is commonly used for:

• 3: These represent the video channels that transmit the video signal from the cameras to the DVR or monitoring system. Typically, the cables are color-coded (usually for BNC connections).
• 1: This is the power cable, which supplies power to the CCTV cameras. This is especially useful for cameras that require external power sources, instead of being powered through Ethernet.

The "Outdoor" designation suggests that the cable is designed to withstand the elements, such as UV exposure, moisture, and varying temperatures. It's typically made with a durable outer jacket (like PVC or PE) to protect the cables from weathering.
