A DVR or NVR security system is a choice you have to make before setting up a video surveillance system. It matters a lot since it decides the cost, the installation, the best video quality you could expect.
Now scroll down to find all you need to know about the DVR and NVR, including what does the NVR or DVR stand for, the differences between NVR and DVR, the top digital or network video recorders, and the DVR or NVR system that works best for you.
Comparison | Full Form | NVR/DVR Cameras | Transmission Cables |
NVR | Network Video Recorder | IP (Internet Protocol) Cameras | Ethernet Cables |
DVR | Digital Video Recorder | Analog & Coax Based Cameras | Coax Cables |
NVR vs DVR sum-up: The biggest difference between NVR and DVR is the cameras and cabling they use. A network video recorder (NVR) records IP cameras wirelessly (WiFi NVR) or via Ethernet cables (PoE NVR), while a digital video recorder (DVR) records analog cameras via coaxial cables.
That’s to say, the NVR is for IP camera recording and the DVR is for analog or coax-based camera recording.
After learning what the NVR and DVR system is and their differences, let’s explore the advantages and disadvantages of NVR and DVR, and you will then know which one suits you better.
Check the table below for a quick comparison between the NVR recorder and DVR recorder:
Comparison | NVR (Network Video Recorder) | DVR (Digital Video Recorder) |
NVR/DVR cameras | IP cameras | Analog or coax based cameras |
Recording quality | Higher | Lower |
NVR/DVR system setup | Easier | Tougher |
NVR/DVR camera cost | Higher | Lower |
NVR Systems
The network video recorders has already become the mainstream at this age of Internet, with more and more camera manufacturers and homeowners swap from producing and using DVRs to NVRS.
And all these happened for big reasons. Check the following advantages of NVR systems:
#1. NVR CCTV records higher quality videos
The network video recorders or NVRs are paired up with IP cameras, with a resolution starting from 2MP to 12MP (or higher), which is out of the question for analog cameras in a DVR security system.
And that’s why so many users and tech experts suggest that the NVR systems should be a clear winner, considering that you need enough resolution to identify the intruders’ face and plate number.
NVR System | 2MP, 4MP, 5MP, and 12MP (4K) systems are commonly seen |
DVR System | 720p, 2MP (1080p) are most popular |
* Some security brands have produced 4K DVR security camera systems. However, with improved clarity, the DVR system will lose its price edge, since they need highly priced video processor chips to produce high quality images.
#2. NVR security system is easy to wire
The cabling work is definitely a headache in setting up an NVR or DVR system. Good news is that the NVR security system makes the cable work easy enough even for a beginner:
The WiFi NVR visits cameras through the network wirelessly, so you don’t need to worry about how to run wires to the network video recorder. The PoE (Power over Ethernet) NVR provides both power and network to the cameras via a single Ethernet cable. You may also use an PoE switch to make the long-distance wiring even easier.
Compared with NVR systems, the DVR system needs exact point-to-point connection between the cameras and the digital network recorder, and the analog cameras require both wires for power and data transmission.
NVR System | Wireless or via single Ethernet cable for power & data |
DVR System | Both power cable and audio/video cable needed |
#3. NVR recorder is flexible in placement
As mentioned before, the NVR uses IP network cameras. That’s to say, you can place the NVR virtually anywhere as long as the network is available. By contrast, the DVR CCTVs are rather limited by the coax cable, with a max transmission distance of about 300 ft.
So you are free to place the network video recorder to record anywhere you want, like the front door, backyard, garage, or even the remote shed. And it’s easier to hide the NVR in some hard-to-access spots like the attic, ceiling, inside walls, closet, or even crawlspace if you worry about your NVR gets stolen.

DVR Cameras | Limited by the coax cables |
