It seems like you're asking about a networking cable suitable for connecting an IP camera, specifically mentioning copper flat cable. Generally, for IP cameras, you'd typically use Ethernet cables, commonly known as Cat5e or Cat6 cables. These cables are designed to transmit data reliably over short to moderate distances, which is perfect for connecting IP cameras to your network.
As for the "copper flat" aspect, it's possible you're referring to flat Ethernet cables. These cables have a flattened design compared to traditional round Ethernet cables, which can make them easier to run under carpets or along walls. They offer the same performance as their round counterparts and are often used in situations where aesthetics or space constraints are a concern.
When selecting a cable, make sure to choose one that meets your specific requirements in terms of length, durability, and compatibility with your IP camera and network setup.
