Have you decided to install a surveillance system for your house but are unsure whether to use a digital video recorder DVR vs NVR?

Considering they are both data-based surveillance systems and record information digitally, we want to clarify and dispel any myths and help you comprehend the differences between DVR vs. NVR.

The two types of systems share many similarities—they both record video and can be accessed remotely—but they also have some crucial differences.

In addition, we will talk about the pros and cons of each system so that you can make an informed decision based on your own needs.

Without any further ado, let's get started!

DVR – How Does it Work?

What is DVR?

DVR stands for Digital Video Recorder and is a device that records TV programs and then allows you to watch them at your convenience.

The DVR keeps all your recordings in a storage device called a hard drive, much like your computer's hard drive. As with a hard drive in a computer, the data is stored magnetically on metal plates, which is why it's called a hard drive.

The hard drive in a DVR can hold hundreds or even thousands of hours of programming. When you record something, it gets stored as digital bits of information on these plates.

How does a DVR work?

Through their cable connections or satellite dishes, DVRs transmit bits of information to your TV set, which are converted into pictures and sounds by the TV set's decoder box (called an A/V receiver).

A typical DVR may have two tuners: one for local channels and one for cable channels (or both combined).

In the early 2000s, cable companies began offering DVRs as part of video services, first letting customers rent the device and then starting to integrate it with their receivers in 2010. 

DVR System Components

DVR systems are vital to a CCTV system setup. Recorders and storage devices help store and record video from all cameras in the system so you can view them retrospectively.

The DVR unit is connected to the cameras via coaxial BNC cables, which carry both power and video signals.

The DVR recorder has an AD (analog-to-digital) encoder built-in, which converts analog video signals into digital data that can be stored on its hard drive.

This saves space as well as offers greater flexibility when it comes to editing footage later on.

NVR – How Does it Work?

What is NVR?

NVR is a closed-circuit television system that records and stores video footage. The term stands for "network video recorder." A Network Video Recorder (NVR) combines hardware and software that allows you to record video from IP cameras.

NVRs are commonly used in surveillance systems to record footage from multiple cameras. There are many different brands, models, and types of NVRs available.

There are many other brands, models, and types of NVRs available.

How Does an NVR Work?

An NVR can be installed onsite at your home or business or offsite at a security company's office. To start recording with an NVR, connect it to your internet router using an Ethernet cable or wireless connection. 

Once connected, the NVR will automatically detect any IP cameras connected (if you have more than one).

The process for setting up an individual IP camera with an NVR varies depending on the brand of camera and software used in conjunction with your system. Generally, it involves configuring each camera's settings through its web interface or mobile app.

NVR System Components

IP cameras

Video cameras with IP technology is the most recent and considered the easiest to use. These cameras can connect directly to the internet and transmit live video over a home Wi-Fi network. You can also indirectly relate to the NVR recorder if you need additional storage space.

Ethernet cables

IP cameras are connected to NVR systems via Ethernet cables. These cables come in various lengths to choose the best suits your needs.

NVR recorders

An NVR recorder is a device that allows you to store recorded footage from all of your IP cameras on one device instead of having multiple DVRs for each camera location. 

This makes it easier to review events in case something happens in one place but not in all areas.

NVRs are used by businesses to record security events, store them and allow users to access the recordings using their mobile devices or PCs. 

Police can access video footage from anywhere in the world, and it can help them solve crimes.

NVR – Pros and Cons

Which one is Better: DVR vs NVR?

The answer to this question is not as simple as it may seem. Both DVR vs NVR have their benefits and drawbacks.

NVRs typically only work with digital footage, while DVRs convert analog footage into digital format.

NVRs or Network Video Recorders are similar devices except that they connect directly to the network instead of being physically connected to a TV or monitor.

DVR and NVR can be used interchangeably in most cases. However, there is a significant drawback associated with NVR. A hacker can use your surveillance system with NVR in order to break into your company's internal network and steal information from your servers if he gains access to your network.
