When you’re looking to upgrade your security camera system, it’s important to get familiar with the available technology and how to use it. This includes CCTV surveillance system basics, as well as whether you want an NVR or DVR system.

The Basics

Network Video Recorders (NVR) are the heart of modern surveillance. They connect to their cameras or your building’s network through CAT 5 Ethernet cable, the same cable used for internet access. Advances in NVR recording and systems have resulted in many advantages over traditional Digital Video Recorders (DVRs), which connect with coaxial cable. Many of these advantages are now defining business and home security. NVRs are designed for optimal security through IP cameras and monitoring. They also install more easily, delivering power and video footage through a single Ethernet cable.

The Best Around

So, what is NVR? It’s the gold standard for modern security systems, with many key benefits. If you’re looking to buy a new security camera system for your property or want to upgrade from analog or HD-over-Coax security cameras to IP security cameras, you’ll need a commercial-grade NVR so you can enjoy the full functionality and use of a complete security system.

How it Integrates with Your System

You may be asking, what is an NVR in a CCTV system exactly? It’s a type of recorder that uses Power-over-Ethernet technology to encode and process video data in IP security cameras. That same cable streams the data from the NVR to the database for storage and viewing. The best NVR systems also allow remote viewing on your phone, tablet, or computer.

IP security cameras are connected to the NVR using a single CAT5/6 ethernet cable. Each of the connected IP security cameras in the network is assigned a specific IP address, which the NVR recognizes and accepts. Unlike DVRs, the video feeds from IP security cameras to an NVR are transmitted via the internet. This internet connection allows for cloud-based viewing.

Real-time, Crystal-Clear Video

If you’re still wondering “what is an NVR” and how it works, you should know that it features multiple high-quality feeds from IP security cameras that are strategically mounted around a business or property. Most of the IP video recorders allow you to view in real-time, store, retrieve, and search for videos. The videos from these cameras are all in high-resolution, with crystal clear pictures.

Most NVRs support real-time 30fps video recording and 1080p to 4K Ultra HD resolution. Many also support Wide Dynamic Range, which allows for better low-light video. An NVR is ideal for businesses or properties where security is paramount. This is especially true if there are various sensitive or vulnerable areas, such as entry and exit points, that need constant surveillance to ensure security, prevent theft, monitor workers, or ensure the safety of loved ones. 

Benefits of a Network Video Recorder

Now that we’ve answered what an NVR system is, let’s have a look at some of the benefits of network video recorders.


Network video recorders can operate 24/7 and carry a wide range of features that ensure maximum surveillance system functionality. In a world where more businesses and homes are turning to new IP security systems, NVRs provide a reliable video recording and remote viewing solution from anywhere, anytime.

High Resolution

NVRs provide much higher quality video footage and images from IP security cameras. They easily support 1080p security cameras and even work with the latest surveillance 4K Ultra HD security cameras. Once you know what an NVR is, move on to learn more about the latest 4K security systems that include a commercial-grade NVR.

The latest NVRs come with user-friendly software interfaces that make it easy to configure each camera and control surveillance monitoring via PC, smartphone, or tablet over the internet. Look for a system that comes with free software and mobile apps, and avoid any that charge a monthly fee. You can easily configure settings for motion detection, event detection, recording schedules, and more. What’s an NVR camera? It’s one that’s incredibly user-friendly.

Plug-and-Play Installation

Installing an NVR and connecting the IP cameras is as easy as plug-and-play. Plug in the wired security cameras via an ethernet cable or connect your wireless cameras, and your NVR should automatically detect the security cameras and provide video footage from each of them. NVR is what the gold standard for connection should be.

Flexible and Scalable

One thing that defines what an NVR in CCTV system is, is flexibility. Because NVRs rely on a network, they’re much more flexible and scalable when it comes to installation. IP security cameras can be installed anywhere on a property so long as there is an internet connection. This type of flexibility is beneficial when you want to upgrade your security system.

NVRs can support multiple security cameras to suit your needs. Scalability is always vital when buying a complete professional-grade security system.
