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

All the cameras in the field of security and surveillance require centralised video recorder for ordering transmit and archiving footage as captured. DVR or Digital Video Recorders evolved right from older VCR models. Then you have the NVRs which represents the next steps in the evolution of the current video recording technology. If you can check the DVR and NVRs side by side, you can compare the differences and then opt for the right response now.

Resolution based on the recordings:

  • DVRs are offering what is known as D1 resolution. It is also termed as the traditional video quality, as used in closed-circuit TV systems. 
  • D1 mainly equates to a resolution of around 720 x 480, which is also termed to be the standard resolution over here. 
  • On the other hand, you have the NVRs, which can record at the highest resolution of 1080p, known for its most top definition results. This system helps in offering significant improvement in the field of video quality over DVR systems. 
Regarding comparison, 1080 p equates to a promising resolution of 1920 x 1080. This helps in resulting in a much brighter image in the end.
Make sure to get this point straight before you finally head for the right surveillance system Philadelphia in town.

Connections established for the cameras:

  • Connecting some of the analogue cameras with a current DVR system is done by directly plugging BNC cable from DVR into the camera. For connecting to some more cameras to DVR systems, you have to work on some of the added wires. 
  • DVR systems are somewhat difficult to scale up mainly because once every BNC connection is primarily occupied by the camera. For that, you have to purchase an entirely new form of DVR before adding another one to the system.
  • DVR also helps in connecting cameras near the recorder. In that case, the quality of the video will start to degrade quite a bit.
  • NVR helps in eliminating these issues as it is connected directly to the network. IP cameras are connected to the same system, usually by way of the PoE switch. After that, the footage is transmitted to NVR.
  • Systems around NVR are more natural to scale up when compared to DVR systems as it can accept new camera once added to the network. In worst cases, all you need is an added POE switch.
  • Some of the IP cameras are also termed to be wireless and can always transmit footage to NVR over Wi-Fi. You won’t find any proximity limit as long as the camera is well-connected to the same networks as NVR.
  • The downside of NVR is that not every IP camera can work with this system. So, you have to be sure of the compatible ones with video recorder before making a purchase.
Always be sure to get these points straight before you finalise on the perfect system for your surveillance cameras. The market has so many options. So, choosing the right one among the lot is not that tough.
