If you’re shopping around for a video surveillance system, you’ll need to choose between the following 2 types of systems:
- NVR (Network Video Recorder) systems
- DVR (Digital Video Recorder) systems
Both systems above perform the same function—they record video footage. They just differ in how they record the footage.
Our professional advice? If you’re building your security camera system from scratch, choose an NVR system. NVR systems rely on newer, more advanced technology and therefore offer higher image/video quality (among other benefits).
We’ll explain how both NVR and DVR systems work then we’ll outline the pros and cons of each system below.

NVR vs DVR: How they Work
NVR stands for Network Video Recorder. NVR systems record and store video footage directly from the network it lives on. These systems work with an advanced type of camera, called IP cameras. IP cameras can actually capture and process video and audio data themselves. They do so using either an ethernet cable or wirelessly via an existing WiFi network.
DVR stands for Digital Video Recorder. These systems are considered the older “legacy” option. Unlike an NVR system, DVR systems work with analog cameras, which can’t process video footage. Instead, the analog cameras stream raw video footage to recorders via coaxial cables. From there, the recorder processes the video footage.
Once the video is processed, both DVR and NVR systems work the same. After connecting to a smartphone or any other viewing device, you can easily access and view your video footage as needed.
Now that we know the difference between how NVR and DVR systems works, let’s look at what those differences mean in terms of pros and cons of each system.
NVR Surveillance System: Pros & cons
Can record video and audio; DVR only records video
Cost, typically NVR systems are more expensive
Better image quality
Software can be harder to use
More system flexibility
Better coverage, 1 camera has multiple lenses
Can be wired or wireless; DVR cannot be wireless
Only needs 1 cable for video, audio and power
Can be used to identify faces, license plates, etc. due to higher image quality
DVR Surveillance System: Pros & Cons
Less expensive than NVR systems
Lower frame rates and lower image quality than NVR systems
Simplicity, easier to set up and operate than NVR systems
Requires extra cables and wires, more complex installation process
Image quality is improving (for systems using HD over Coaxial technology)
Separate power source required
Less coverage, it takes multiple analog cameras to cover the same area as 1 IP camera
Only good for observing, can’t record audio
