When setting up a CCTV or security camera system, one of the most common questions is whether to choose a DVR (Digital Video Recorder) or an NVR (Network Video Recorder). Both are used to record and manage camera footage, but they work in different ways. Understanding the difference will help you choose the right system for your home or business.
What Is a DVR?
A DVR (Digital Video Recorder) is used with analog or HD analog cameras. In a DVR system, the camera sends raw video footage to the DVR through coaxial cables. The DVR then processes, compresses, and stores the video.
Key Features of DVR:
- Works with analog / HD analog cameras
- Uses coaxial cables (RG59)
- Video processing happens inside the DVR
- Generally more affordable
- Common in traditional CCTV setups
What Is an NVR?
An NVR (Network Video Recorder) works with Internet Protocol cameras. In this system, cameras process the video themselves and send digital video data over a network (LAN or internet) to the NVR.
Key Features of NVR:
- Works with IP cameras
- Uses Ethernet cables (Cat5/Cat6)
- Video processing happens in the camera
- Supports higher resolution (2MP, 4MP, 4K)
- Ideal for modern and smart surveillance systems
