How Security Camera Recorders Work

NVRs and DVRs by CCTV Security Pros both allow for managing, viewing, recording, and storing live or archived surveillance footage from connected cameras. You can access all these functions from any device.

  • DVRs - Connect to their cameras with a coaxial cable (RG59) and have a separate cord for power. Many older buildings are pre-wired for these types of systems.
  • NVRs - Connect to their cameras with Ethernet Cable (CAT5/6). They only use one cable for power and video. This is called Power Over Ethernet technology (PoE)

Each of these video recording systems comes with pros and cons, including the video quality of the cameras they support. Before directly comparing NVRs vs DVRs, ask these questions to help determine your monitoring needs.

Determining the Right System

  • What do I want to protect or monitor?
  • How do I want to install my security cameras or system?
  • What hardware am I dealing with?
  • Who will be maintaining my surveillance network?
  • Who needs to access my security system?
  • How big is my property?
  • How many security cameras do I need?
  • How best can I monitor the security cameras?
  • What is my budget?

The answers to these questions can help you understand the benefits of NVR vs DVR systems, what security surveillance features you want, the best way to install your security cameras, and how big of a system you need. From there, you can determine which is best for your needs based on the differences between DVR and NVR systems.

HVR Recorder Systems

You may have heard the term HVR in your research for the best security camera recorder. These are Hybrid Video Recorders that can accept video from cameras of multiple types, though these system types are not recommended.

DVR & NVR Power Consumption

Both DVR and NVR systems consume a similar amount of power, typically less than 10 watts per camera. The difference in power consumption comes with the features. Infrared night vision and higher quality (4K) video will demand more power. In comparing NVR vs DVR surveillance systems, both support these capabilities, but NVR systems more readily feature them.

NVR vs DVR Differences Outlined

NVR Basics

NVRs are the heart of today’s advanced IP security camera systems. Surveillance technology has greatly improved in just a few short years, with NVRs now a mainstay in home and business surveillance. These recorders are designed to be used with IP security cameras. They rely on Power-over-Ethernet technology and transmit power and video over CAT5/6 Ethernet cables. When it comes to NVR vs DVR, NVR is the more streamlined of the two.

NVR Technology

To really understand if NVR is better than DVR, you have to understand its underlying video technology. NVRs use PoE technology to encode and process video data in IP security cameras, which then stream the data to the video recorder, which saves the video footage. One major difference between DVRs and NVRs is how the video footage is transmitted. Unlike DVRs, video footage is transmitted to the NVR via the same network infrastructure as your internet access. 

NVR Picture Quality

In the battle of NVR vs DVR, NVR wins out in its picture quality support. NVRs support extremely high-resolution security cameras - up to 4K Ultra HD. If you’re looking to upgrade from analog systems or want a new security system with IP security cameras, you’ll need a professional-grade NVR so you can enjoy the full functionality and use of a complete surveillance system. These recorders are ideal for use where enhanced security is needed.

NVR Key Features

As we continue analyzing the difference between DVR and NVR security camera recorders and look at NVR vs DVR systems, here are some key features of network video recorders and their cameras: 

  • Crystal clear surveillance video up to 4K Ultra HD picture quality
  • Remote viewing of live or recorded video via PC, smartphones, and tablets with no monthly fees
  • Easy-to-use and fully-functional web interface
  • Options for recording video footage 24/7, on schedule, or on motion detection
  • Easily view, record, playback, and retrieve time and date-stamped video footage
  • Compatible with different types of security cameras
  • More advanced H.265 video compression technology that produces better video quality at the use of less storage and bandwidth
  • Surveillance-grade hard drives for storing recorded video footage
  • Multiple Hard Drive Bays to support your storage needs
  • External POE Switch that supports multiple cameras (Up to 64 security cameras)
  • 200 Mbps Incoming Bandwidth
  • HDMI and VGA Display Output for increased functionality

There are a few more benefits to NVRs in the comparison between NVR vs DVR systems.

DVR Basics

DVRs record both analog security cameras and HD-over-Coax security cameras. A key difference between DVR and NVR security camera recorders is that with DVRs, each camera requires two cables, one for power and another for transmission of audio and video footage. DVRs support security cameras with a resolution of 1080p and are hardwired. These recorders are tried-and-true security systems and are still used by millions of businesses.

Many buildings come pre-wired for DVRs. They’re considered the “old standard” for video surveillance, although they lack some of the extra features that IP systems and NVRs offer. They’re perfect for enhancing an analog system with better cameras and more modern features without changing the wiring.

DVR Key Features

To fully grasp the difference between DVR and NVR security camera recorders, here are the key features of digital video recorders:

  • HD security camera DVRs deliver up to 1080p video recording, with some models allowing higher resolution recordings
  • Live remote viewing via PC, smartphones, and tablets
  • Multiplex surveillance with live footage viewing, video footage playback, 24/7 recording and storage of surveillance video, simultaneously
  • Reliable surveillance monitoring and motion detection capabilities
  • Easy retrieval of the recorded surveillance footage - date & time stamped
  • Pre-installed surveillance-grade hard drives for reliable video storage
  • User-friendly surveillance monitoring interface for streamlined and simplified setup, installation, and management of your DVR security system
