Coaxial cables and network cables are the two most common types of cables used for camera wiring. Coaxial cables are used for analog cameras, while network cables are used for IP cameras.
| Cable Type | Description | Advantages | Disadvantages |
| — | — | — | — |
| Coaxial Cable | A coaxial cable consists of a center conductor, insulation, and a braided shield. | High-quality video signal, resistant to interference | Expensive, difficult to install |
| Network Cable | A network cable consists of four pairs of twisted wires. | Fast data transfer rates, easy to install | Prone to interference, lower video quality |
Tips and Tricks for Camera Wiring
Here are some tips and tricks for camera wiring:
- Use high-quality cables and connectors to ensure a clear video signal.
- Keep the cables away from power sources and other devices that may cause interference.
- Use a cable tester to test the cables for any damage or defects.
- Label the cables clearly to avoid confusion during installation.
- Use a drill and bits to drill holes for the cables, rather than using a hammer and nails.
