Analog vs. Digital CCTV Systems

Understanding the difference between analogue and digital CCTV systems is crucial for making an informed decision.

Analog CCTV Systems

  • Definition: Analog systems transmit video signals in the traditional format, which is then converted to a digital format for storage or viewing.
  • Advantages:
    • Cost-effective
    • Suitable for smaller setups with fewer cameras
  • Disadvantages:
    • Limited resolution
    • Requires a direct connection to the recording device

Digital CCTV Systems

  • Definition: Digital systems, also known as IP cameras, transmit video signals in a digital format without the need for conversion.
  • Advantages:
    • High resolution and image quality
    • Scalable and flexible
    • Remote access and monitoring
  • Disadvantages:
    • Typically more expensive than analogue systems
