DVR vs NVR: Which One Is A Better Option For Footage Storage?

When it comes to security, many people decide on a DIY approach, which is excellent if you have the knowledge or resources to hire someone to help. However, it is better to go with a proven solution when it comes to something as crucial as enterprise-level security, even if it means shelling out a bit more.

A DVR and NVR, better for enterprise security, is not a trivial decision. You will most likely be making a decision for an extended period. After all, it will ultimately define the landscape of enterprise security and everything it will be held responsible for.

This blog will look at the different aspects of these DVR and NVR solutions and how you can decide which one is the best for your needs.

What is a Digital Video Recorder (DVR) Camera System?

Digital Video Recorders (DVRs) are a type of surveillance technology that records video and stores it digitally on a hard drive. DVR systems are often used in CCTV installations and can process data at the recorder level.

Most DVRs work with analog cameras, meaning they take raw video input from analog cameras and then process it. DVR-based surveillance systems are typically wired, meaning all the components are connected via wires.

What is a Network Video Recorder (NVR) Camera System?

NVR or Network video recorder is the camera system that processes data at the camera level before sending it to the recorder for storage and viewing. It receives IP camera streams via a local network. It can be a wired or wireless system.

The NVR system doesn’t have video input connectors because it’s not receiving raw video inputs; it’s getting video streams from the network instead.

To connect to the network, you can plug the NVR directly into the local network via the LAN port on the NVR. Alternatively, you can plug the cameras into the PoE switch at the back of the NVR with a single Ethernet cable.

DVR vs NVR: The Complete Comparison Between The Both

While DVR vs NVR difference depends on many factors, while both serve the purpose of recording your video feed, there are many differences between them. However, here are the main differences between these two. Let’s first figure out what they are.

•  Cable and Wiring

The most noticeable difference in DVRs is the type of cable it uses: Coaxial cables. It records video in a digital format but does not support the power supply on the same line. So it needs another thread to carry electrical signals. The other cable transmits video through data signals. Also, these cables are stiffer and broader, so it makes installation a big challenge.

In NVRs, video recording software programs store digital video onto storage devices like a USB flash drive, SD memory card, and many more. They use regular Ethernet cables.

• Camera

DVRs use analog cameras that are connected with a wire. The analog camera transmits the footage in analog signals to the DVR to process it further. Then it is stored externally on some local storage in a hard drive.

NVR systems use IP CCTV cameras, which are standalone image-capturing devices that use standard Ethernet cables. Unlike analog cameras, IP cameras do not require a local recording device, only a local network.

• Audio Transmission

In DVRs, the analog video signal does not support audio transmission. So to have the audio as well, you need to add an audio RCA connector to the DVR, which requires additional installation.

NVRs supported by IP cameras are an excellent choice for those needing a robust, reliable camera as it supports recording and transmitting audio and video.

• Distance Covering

The distance covered by DVR and NVR can depend upon the length of the cables. In the case of DVR security systems, the space you may want to cover will be limited as wires have a specific size they can expand to.

However, on the other hand, NVRs can or cannot be wired so that the case can be a little flexible. So, It can encompass long-distance data transfer and remote viewing. You can spread it across any distance as long as the network is available

• Support of Cloud Storage Services

DVR systems do not have cloud video storage services as it is a very traditional form of the recording system.

So most NVRs can certainly use cloud storage for surveillance video information storage as it is supported by power over the internet. With some extensions, NVRs can also store your footage directly into cloud storage.

• Cost benefits

DVRs are priced lower and are suitable for domestic use. However, with more add-ons and installation for advanced features, the cost of DVR-based security systems keeps increasing. 

NVRs, in comparison to DVRs have a better price edge as they come with in-built advanced features. 

DVR vs NVR: Pros and Cons and what you can keep in check

Here is a brief comparison of the pros and cons of DVR vs. NVR systems. 

Wrapping Up

All in all, DVR vs NVR systems record video onto a hard drive. What differentiates them is their design and implementation, setup, processing of raw data, and more.
