What is a DVR and What is an NVR?

NVR stands for Network Video Recorder. Just as you would guess by the name, NVRs record and retain HD video direcly from the network. They do this by using Cat5 or Cat6 Ethernet cables. NVR security camera systems support IP camera.

From there, NVRs can be broken down in 2 further sub-categories. The PoE NVR uses the aforementioned technology to connect IP cameras with Ethernet ports. The other type is a WiFi NVR, which connects cameras wirelessly via your existing WiFi network. As a result, WiFi NVRs have no camera ports.

Conversely, DVR is short for Digital Video Recorder. DVRs are typically used in HD analog security camera systems. They represent a more time-tested, traditional form of security. They process uncompressed videos via coaxial cables and then proceed to compress the HD footage to a digital signal before transmission. DVR systems support HD analog security cameras.

Important: NVR and DVR security systems typically come with a few standard options for size as well as capacity. They come in 4-channel, 8-channel and 16-channel options, which shows how many cameras can be connected within the system at the same time. If you have large-scale needs, you can also find 32-channel NVRs, though they are not as common as the types mentioned here.

How Do NVRs and DVRs Work?

An NVR records and saves encoded videos that are transmitted to it directly from IP camera via the network. That means these network video recorder systems do not require specific video processing hardware.

On the other hand, a DVR has a small piece of hardware that encodes and processes the HD video sent to it by analog cameras. This converts the raw footage into a digital format before the user is able to view live footage or recordings.

NVRs and DVRs are both used for recording HD video as well as storing important video data. After connected to a PC, tablet, smartphone or other viewing device, your NVR and DVR security cameras are easy to access, view and manage as needed.

DVR and NVR – Key Differences

The biggest differences for DVRs vs NVRs are the cameras and cables they use. A network video recorder  records footage from HD IP camera either via Ethernet cables (PoE) or wirelessly (for WiFi IP cameras). Conversely, digital video recorders gain their video feed from HD analog cameras with coaxial cables.

You need an NVR for HD IP security cameras, while you need a DVR for HD analog security cameras.

Recorders	Full Name	Types of Cameras	Cabling
NVR	Network Video Recorder	HD IP Cameras	Ethernet (PoE)
DVR	Digital Video Recorder	HD Analog Cameras	Coaxial Cables (BNC)

Using Video Recorders Without Internet Access

One key factor that may be relevant to many users is that both DVR and NVR security systems can be used without internet access. This is particularly useful for those who live in remote areas where internet connections are difficult to obtain. Along with that, some people prefer to keep their security solutions away from internet access.

If you simply want to record with your NVR or DVR camera system, you don’t have to connect it to the internet. You can have the cameras work on their own proprietary network.

You only need an internet connection for your NVR or DVR system if you want to view your HD video feed remotely or receive mobile push notifications.

DVR vs NVR – Choosing Between Them

Now a that you have a better idea of the difference between the two recorder types, we can compare and contrast the pros and cons of both. This will help you make an informed decision if you are looking for a new HD security camera system.
The chart will give you a quick breakdown of the 2 types head-to-head. Keep reading for more details!

NVR Security Camera Systems

With the overwhelming popularity as well as utility that comes along with the internet, NVR systems have become extremely popular. From the installer/integrator level, all the way up to the manufacturer level, NVR systems have become more of the industry standard. This is due to their easy remote accessibility as well as their ease of setup.

Here’s a list of the other important reasons that the market is shifting to NVRs in many cases. Let’s explore:

1. NVR Recording Quality is Unmatched

NVRs can be paired with HD IP cameras that boast the finest viewing quality in the industry. These high definition security cameras and systems typically feature anywhere from HD 1080P to Ultra HD 4K resolution. Some HD analog systems can achieve the same, but the overall detail and fluidity always goes to an NVR system over a DVR system.

As a result, most tech aficionados would site HD IP security camera systems as the obvious winner between the two. At the end of the day, a clear image, with enough detail to see people’s faces or the license plate numbers on a car, tends to be the top priority!

*There are options on the market that go up to Ultra HD 4K resolution in HD analog. This does eliminate some of the advantage for HD analog overall (in reference to the economical advantage, discussed later in this post), but we do highly suggest these ultra HD 4k analog options for those who are either more comfortable/familiar with the technology. Also, those who already have coaxial or BNC cabling already wired for an analog system, but are looking to upgrade will find value in this product line as well!

2. NVR Security Camera Systems are Easy to Set Up

One part of setting up a fully-wired security camera system is that running cables can be a little bit of a hassle. Luckily, NVR systems have employed the power of PoE to help remedy this issue. This makes HD IP security systems truly DIY.

If you choose to go the WiFi route, you wont even need to worry about running network cables. Our HD IP WiFi camera and systems connect via your wireless router to simplify things even further!

Back to the PoE side of things, wiring is made easy by the Ethernet cable which provide both power and video to the cameras. This makes most installation a breeze. Plus, with the help of PoE switches, extended networking for long-distance coverage is made easy.

3. NVRs Are Easy to Place Anywhere

As this section has covered, NVR security camera systems are all about easy set up as well as installation. You can place the recorder almost anywhere on your property as long as it can successfully connect to your network. On the other hand, DVR analog systems are more limited with their set up options, with coaxial cables maxing out at just a few hundred feet.

Along with that, the NVR is much easier to place in hidden locations around your home or business. Since you’ll experience much more ease with networking and wiring, small attic spaces, closets and other hidden areas are much easier for you to work with.

4. PoE and WiFi Systems Are Hassle-Free and User-Friendly

If you were under the impression that NVR security camera systems require complex configuration and networking, you are wrong!

With the magic of P2P camera technology, you can set up your system with zero configuration.

After  powering on the system and downloading the software, you cameras should automatically pop up on the network device list. It’s that simple!

See how our HD IP cameras dominate the list of  best surveillance cameras!

DVR Security Camera Systems

If you are looking for economical security solutions, you are in the right place. Though these analog systems have a few disadvantages, they are good for those who already have familiarity with the technology or just need an upgrade. These are more than sufficient for the average household, especially if your home is already wired an older analog security system.

1. Running Wires Can be Difficult

The trickiness of the wiring can be a disadvantage here.

Needing separate wires means needing to run two separate cables as opposed to the PoE counterparts. Furthermore, if you need long-distance access, coaxial cables may fall short.

* An important note here, our newest HD analog security systems come with consolidated BNC cables that run the data and power cables in tandem like a single cable. The cost goes up, but this is a comparable solutions to PoE!

2. Image Quality Suffers

There’s no way around it. DVR systems don’t offer the sharpness of details nor the fluidity of their PoE counterparts. When you save for your budget, you sacrifice a little bit of image quality. Keep that in mind as you shop!

It is important to mention again, that HD analog solutions can go all the way up to Ultra HD 4K. Keep in mind, these enhanced options are often more expensive.

3. Distance Limitations

As we mentioned earlier, you may experience some distance limitations with coaxial. We’ll keep this section short (see what we did there?).

4. Potential Maintenance Cost

Coaxial cables are analog systems’ conduits for data transmission. Unfortunately, these types of cables are often vulnerable to inclement weather and precipitation. Cable damage means the need for repair or replacement. As a result, you could experience more cost and down time for the affected cameras.

It is important to note that our HD Analog systems have been vastly improved compared to the traditional tech we are discussing here. See more below!

The Final Say – DVR vs NVR Security Camera System

The choice between the two types of recorders really depends on your comfort level with wiring.

If you are a newbie and don’t consider yourself tech savvy, you need to go with an NVR system. PoE or wireless network connections are the way to go here.

Choose analog if you are trying to save money and have some level of comfort with wiring.

In general, HD IP camera technology is going to make a much better user experience.
