The type of cable used for security cameras depends on the type of camera and the installation setup. Here are the most common types:
1. Coaxial Cable (For Analog and HD Over Coax Cameras)
- RG59 Siamese Cable – This is the most common for CCTV (analog) cameras. It combines video (coax) and power (two-wire) in one cable.
- RG6 Cable – Similar to RG59 but has a thicker core, allowing for longer transmission distances.
- BNC Connectors – Used with RG59 and RG6 cables to connect to cameras and DVRs.
2. Ethernet Cable (For IP Cameras)
- Cat5e – Supports up to 100 meters (328 feet) of transmission, suitable for most IP cameras.
- Cat6 – Offers better speed and reduced interference, supports up to 100 meters but with higher bandwidth.
- PoE (Power over Ethernet) – IP cameras can receive both power and data through a single Ethernet cable using a PoE switch or injector.
3. Fiber Optic Cable (For Long-Distance and High-Resolution Cameras)
- Used for very long-distance installations or when high bandwidth is required.
- Requires special converters to work with standard IP cameras.
4. Power Cable (For Non-PoE Cameras)
- 18/2 Power Wire – Commonly used to supply power to cameras separately when power is not transmitted via the main video/data cable.
Would you like help selecting a cable for a specific setup?
Yes, security cameras can use coaxial cables, but it depends on the type of camera.
When Do Security Cameras Use Coaxial Cable?
- Analog CCTV Cameras – Traditional analog cameras (CVBS) use RG59 or RG6 coaxial cable with BNC connectors to transmit video signals.
- HD Over Coax Cameras – Modern HD security cameras, such as HD-CVI, HD-TVI, and AHD, also use coaxial cable but can transmit high-definition video (up to 4K) over longer distances.
- Siamese Coaxial Cable – A common type used for CCTV, which combines RG59 coax (for video) and 18/2 power cable (for power).
When Coaxial Cable Is Not Used
- IP Cameras use Ethernet cables (Cat5e, Cat6, etc.) instead of coax.
- Wireless Cameras do not require cabling for video but may need power cables.
