Difference Between DVR and NVR
What is Difference Between DVR and NVR
Digital video recorders (DVR) and network video recorders (NVR) are types of video recording systems used for security cameras. NVR systems record and store video footage directly from the network it lives on.
Digital Video Recorder (DVR): Digital Video Recorder (DVR) is mainly used for recording data from analog cameras or coaxial based cameras. It is paired with analog coax based cameras with resolution 2MP maximum. In this system both power cable and audio/video cable needed. It provides limited range service as it is coax cabled. In this signal stability is independent upon the internet working.
Advantage of DVR
- Less expensive as compared to NVR
- Provides good image quality over HD
- Easy to operate
Disadvantage of DVR
- Requires separate power source
- Generally low quality video
- Less coverage area
- Can not record audio
- Complex installation process
Network Video Recorder (NVR): Network Video Recorder (NVR) is mainly used for recording data from IP cameras wirelessly over a network. It is paired with IP cameras with resolution ranging from 2MP to 12MP or higher. In this system wireless or single Ethernet cable is used for power & data. It provides long range service upto which network access is available. In this signal stability depends upon the internet working.
Advantage of NVR
- Can record both video and audio
- Provides better image quality
- Provides more system flexibility
- Provides coverage area
- Can be wired or wireless
- Requires one cable for power and video
Disadvantage of NVR
- More expensive
- Software may be difficult to use
- Requires networking knowledge to operate and troubleshoot
