It looks like you're asking about a "CCTV Cable INDOOR 3+1." This typically refers to a type of cable used for CCTV (closed-circuit television) systems. Here's a breakdown of the term:

• CCTV Cable: Used to connect the cameras to the DVR or NVR (recording system). It carries video signals and sometimes power.
• INDOOR: Indicates that the cable is meant for indoor installations. These cables may not have the weatherproofing or UV resistance necessary for outdoor use.
• 3+1: This typically refers to the structure of the cable. The "3" usually indicates 3 separate wires or conductors (for video, power, and ground), and the "1" is a fourth wire, typically used for either additional power or audio (if the camera supports that).

This type of cable setup is common for CCTV installations in homes or businesses where the cameras are used indoors, such as in offices, homes, or stores.
