Difference between NVR and DVR


The use of NVR and DVR helps in video recording. In today’s times, it has become a prerequisite for all commercial business owners. Both of them play a key role in domestic applications to help deter and prevent crimes. Major businesses in Colorado have NVR and DVR installed. Both help businesses deter and prevent crimes.

What is NVR?

  • NVR is a network-attached computer system that has a software program for video recording typically in a digital format to storage devices like USB, disk drive, hard drive, or memory card.
  • The major difference between NVR and DVR is that NVR has no video input connectors as it receives video streams from the network. It has easy-to-connect features that allow the network to plug in the NVR directly to the LAN port or plug cameras.
  • NVR system uses an IP camera which is a stand-alone device to capture images. These IP cameras can process video and are capable of recording and transmitting audio.
  • The NVR system makes use of standard Ethernet cables which is easy to use due to their thin size, cost-effectiveness and easy-to-adapt feature.
    • Better image quality for businesses
    • More system flexibility
    • Easy to install Some of the important advantages of the NVR system include
    • Easy to adapt

What is DVR?

  • DVR systems are typically designed for recording video in a digital format.
  • They are lower-priced security systems compared to NVR therefore they are widely used by small businesses. Due to the price factor, they have large-scale applications in the domestic sector.
  • The DVR system uses analog cameras. These cameras are responsible for streaming an analog single to the recorder, which then processes the video data.
  • The coaxial cable presents functions to connect the analog camera to the DVR system.
  • DVR recorders rely heavily on AD encoders, which are primarily responsible for processing the raw data streaming from the camera into viewable footage. Therefore it requires every camera in the security system to be connected to both the recorder and a separate power source.

Some of the important advantages of the NVR system include

  • Minimal bandwidth usage
  • Stability of signal
  • Lower cost

Which is better? NVR or DVR?

If you are new to security surveillance and starting from scratch we recommend you to install a DVR system with IP cameras and use your existing data network instead.

But if you only need assistance with broadcast and to facilitate your team with monitoring from your security room, a DVR network is probably sufficient for you. If you need full off-site monitoring, cloud recording, along with other details of decentralization, an NVR is likely the way to go.
