Cables

CCTV cameras are typically connected to monitoring or recording equipment using coaxial cables or Ethernet cables, depending on the camera type and the system's setup. Here are the two most common types of cables used for CCTV cameras:

• Coaxial Cable (RG59 or RG6): Traditional analog CCTV cameras often use coaxial cables, such as RG59 or RG6, for both video and power transmission. These cables are known for their durability and reliability in transmitting video signals over longer distances. Coaxial cables may require separate power cables or use a Siamese cable, which combines both video and power wires within a single jacket.
• Ethernet Cable (Cat5e, Cat6, or Cat6a): IP-based CCTV cameras, which are becoming more common due to their higher resolution and advanced features, use Ethernet cables for data transmission. Cat5e, Cat6, or Cat6a cables are commonly used to connect IP cameras to network switches or recorders. Power over Ethernet (PoE) technology allows these cables to provide both data and power to the cameras, simplifying installation and reducing the need for separate power cables.

The size of cable used for CCTV cameras depends on the camera type and installation requirements. Coaxial cables like RG59 or RG6 are often used for analog cameras, with diameters ranging from 0.25 to 0.33 inches (6.4 to 8.4 mm). Ethernet cables like Cat5e, Cat6, or Cat6a are common for IP cameras and have smaller diameters, typically ranging from 0.19 to 0.25 inches (4.8 to 6.4 mm). The choice depends on factors like camera technology, transmission distance, and power requirements.

The type of cable commonly used for CCTV (Closed Circuit Television) installations is coaxial cable. RG59 and RG6 are two common types of coaxial cables used for this purpose. These cables are capable of transmitting video signals over long distances without significant signal loss or degradation.

In addition to coaxial cables, twisted pair cables (such as Category 5e or Category 6 cables) are also used for CCTV installations, especially for transmitting data signals in IP-based CCTV systems. These cables are commonly used in conjunction with baluns, which are devices that convert the signals from coaxial to twisted pair and vice versa.

It's worth noting that the specific type of cable used can depend on the requirements of the CCTV system, the distance over which the signals need to be transmitted, and whether the system is analog or digital. Always refer to the manufacturer's specifications and recommendations for the CCTV equipment being used to ensure the proper type of cable is selected for the installation.
