Best One to Choose Between Digital Video Recorders and Network Video Recorders

All cameras in security and surveillance need a central video recorder to order transfer and archive photos as captured. DVR or Digital Video Recorders evolved right from older VCR models. Then you have the NVRs that represent the next steps in the evolution of current video recording technology. If you can check the DVR and NVRs side by side, you can compare the differences and then select the correct response now.

Decision based on the recordings:

  • DVRs offer what is called a D1 solution. Also known as traditional video quality, as used in CCTV systems.
  • D1 corresponds mainly to a resolution of approximately 720 x 480, also known as the standard resolution here.
  • On the other hand, you have the NVRs, which can record at the highest resolution of 1080c, known for its highest definition results. This system helps to offer significant improvement in video quality over DVR systems.

For comparison, 1080 p equals a promising resolution of 1920 x 1080. This helps to result in a much brighter image in the end.
Make sure you get this point right before you finally aim for the right Philadelphia surveillance system in town.

Contacts set up for the cameras:

  • Connecting some of the analog cameras to an existing DVR system is done by plugging a BNC cable directly from DVR into the camera. For connecting to some more cameras with DVR systems, you have to work on some of the extra wires.
  • DVR systems are a little difficult to scale up mainly because once the camera occupies mostly all BNC connections. For that, you have to buy a completely new form of DVR before adding another to the system.
  • DVR also helps connect cameras near the recorder. In that case, the video quality will start to degrade quite a bit.
  • NVR helps eliminate these issues as it is directly connected to the network. IP cameras are connected to the same system, usually via the PoE switch. After that, the photos are transferred to NVR.
  • Systems around NVR are more natural to increase compared to DVR systems because it can receive a new camera when added to the network. In the worst cases, all you need is an extra POE switch.
  • Some of the IP cameras are also known to be wireless and can always transfer photos to NVR over Wi-Fi. You didn’t find any proximity limit as long as the camera is well connected to the same networks as NVR.
  • The disadvantage of NVR is that not all IP cameras can work with this system. Therefore, you must be sure of the video recorder compatible ones before buying.
