How to choose fiber optic lines for surveillance cameras

The most common options are Cat5, Cat5e, Cat6, Cat6a, and fiber optic cables. Each has distinct characteristics, making them suitable for different applications. This blog post compares these cabling options to help you decide which is best for your security camera system. High Bandwidth: Fiber optic cables are capable of supporting data speeds up to 10Gbps or beyond and they carry large amounts of data over extended distances without compromising on video. This type is commonly used for analog CCTV cameras that require both 12V DC power and video transmission. Network (Ethernet) Cable For IP-based surveillance, an Ethernet cable for IP cameras, like Cat5e or Cat6, enables Power over Ethernet (PoE). This simplifies cabling by transmitting both data. Depending on the type of installation, type of cameras and transmission distance, different types of cables are used, such as coaxial cables, UTP/FTP twisted pairs, or fiber optic cables.
