What is DVR and How Does it Work in CCTV Systems?

DVR systems have been the backbone of traditional CCTV setups for years. A DVR records footage from analog cameras and stores it locally on a hard drive. The cameras are connected via coaxial cables, and the DVR acts as the central hub that records and stores video footage.

Key Features of DVR:

  • Analog Technology: DVR works with analog CCTV cameras, which are connected to the recorder via coaxial cables.
  • Cost-effective: DVR systems are generally more affordable than NVR systems, making them a popular choice for budget-conscious buyers.
  • Video Quality: While DVR systems provide adequate video quality for basic surveillance needs, they have limitations in terms of resolution.

Pros:

  • Budget-friendly solution.
  • Simple and reliable for basic monitoring.

Cons:

  • Lower resolution compared to NVR.
  • Requires more physical wiring, making installation a bit cumbersome.
