What Is an NVR Security Camera System?

An NVR security camera system is a type of video surveillance equipment that incorporates multiple IP cameras and a network video recorder (NVR). The cameras capture footage and send it to the NVR for storage. As a user, you can view live or recorded footage from different sites simultaneously using your phone, tablet, or computer. 

You will find two types of NVR security camera systems: wireless and PoE (Power over Ethernet). Wireless systems share data through Wi-Fi networks, while PoE sends data through Ethernet cables. The channel number also serves as a classification for these systems. The number of channels in an NVR system determines how many cameras can be added to the surveillance network; some popular options include 4-channel, 8-channel, or 16-channel variants.

According to recent statistics from Grand View Research Inc., the global market size for Network Video Recorders was valued at USD $3 billion in 2020, with expected growth predictions reaching up to USD $5 billion by year-end 2027. Businesses are increasingly opting for smarter video monitoring solutions that guarantee safety and efficiency against intrusion and theft while assisting remote access and control operations seamlessly, irrespective of location constraints.

NVR vs DVR Security Camera Systems: Which One is Better?

When it comes to choosing a surveillance system for your business or home, one of the biggest decisions you'll have to make is choosing between NVR and DVR systems. Both types of systems have their benefits and drawbacks, so it's important to understand what sets them apart.

  • Differences Between NVR and DVR Systems

One key difference between the two systems lies in how they process video data. In a traditional digital video recorder (DVR) system, cameras are connected directly to the recorder using coaxial cables. These recorders then compress and store footage on an internal hard drive.

In contrast, network video recorders (NVRs) use internet protocol (IP) cameras that transmit encrypted, high-quality digital feeds over Ethernet networks. This eliminates the need for complicated wiring setups required by traditional analog surveillance camera solutions.

Another distinguishing feature favoring NVRs over their conventional counterparts involves Power-Over-Ethernet-enabled devices that encourage both power and data transmission through one cable. Older models would require separate cables, in comparison.

Recent reports from MarketsandMarkets@1 entail growth predictions of $16 billion up until 2025 in the IP-based video surveillance market. It’s fueled by rising infrastructure developments like smart cities and transportation initiatives worldwide, among others.

  • Reasons Why NVR Systems Are Better

While both types of systems can be effective tools for securing your property, many experts consider networked recording technology superior due to better scalability possibilities, ease-of-installation convenience via Wi-Fi connectivity, and additional features like remote monitoring capabilities offered seamlessly via intelligent apps.

The choice ultimately depends on your business needs—whether you need excellent image quality or prefer cost savings while ensuring precision surveillance operations.

NVR Buying Guide: Choosing the Right NVR Security Camera System

An NVR is an excellent choice for a security camera system. It provides advanced features like remote access and control operations seamlessly, irrespective of location limitations, while guaranteeing safety and efficiency against intruders and larcenies. However, with so many options out there in the market for you to choose from, picking the perfect one can be overwhelming.

  • Factors to Consider When Choosing an NVR System

When selecting an NVR system, considering these factors will allow you to make the best choices for your security needs. To ensure thorough surveillance coverage, 

-look for the quantity and specifications of cameras needed, 

-secure storage capacity for a minimum of two weeks of footage, 

-explore camera sensor pixels-per-inch and the viewing angle of the lens for optimal resolution quality.

-inspect connectivity features, including remote access controls and video loss prevention such as ANR (automatic network replenishment).

Based on statistics from Financeonline, it appears that small businesses suffer an average of $100K in inventory loss annually due to burglary. You can guess how important it is that businesses prioritize implementing strong security measures to prevent such losses and to have tangible proof for insurance claims.

  • Types of NVR Security Camera Systems

There are diverse models available for both commercial and residential customers, with different shapes that allow for discrete camera placement without compromising visibility. Check these out-

  • Dome Cameras- These surveillance devices are typically equipped with a dome-shaped housing that provides greater security against tampering. The semi-vandal-proof designs of these security measures can secure critical infrastructure, such as public transportation services like airports and bus and train stations, as well as other similar conditions.
  • Turret Cameras- Similar to dome cameras, these cameras have a round housing but they do not use a polycarbonate dome rather they are made from either metal or plastic with a glass lens cover.  They are sealed against the elements and have higher powered LEDs and can even incorporate visible light without causing any video interference. 
  • Bullet Cameras- Named after their tube-like shape, resembling bullets, these cameras are frequently mounted on walls, poles, or fences where exterior monitoring is needed. As bullet cameras show weather-resistant capabilities, they prove to be workable even under harsh weather conditions.
  • PTZ Cameras – The PTZ (Pan Tilt Zoom) feature is commonly utilized in expansive areas like commercial spaces, warehouses, and harbor fronts. These are the places that ask for wider coverage. This equipment is highly versatile and provides a more comprehensive view if you compare it to traditional cameras with narrow viewing angles.
  • Wireless Cameras- These are Wi-Fi-enabled models that can be remotely connected via wireless network setups. They certainly eliminate the need for complex wiring and cable options. This solution is ideal for locations that have limited or no access path for installing cables.  IP cameras by design can even be transmitted over wireless PtP antennas allowing 1 or more wired cameras to employ a wireless transmission.

Features to Look for in an NVR Security Camera System

Buying an NVR security camera system can be overwhelming due to the different technical terms and endless features available. With that said, it is essential to know the features that matter to you and will enhance your purchasing decision. 

  • Camera Resolution and Quality

It is crucial to consider the image quality of your camera, as it determines how clear recordings are captured. The camera's resolution has a direct correlation with its video quality. Therefore, choosing a higher resolution results in better picture clarity. Typically we expect most high quality cameras to have resolutions of 4MP or greater to deliver exceptional picture quality.

  • Number of Channels Supported

A channel on a NVR or DVR is meant to display a connected camera. Selecting one with additional ports ensures scalability if required later on down the line—the numbers range from 4 channels to 256 channels depending on the selected recorder. 

  • Storage Capacity and Expandability

Storage capacity options are key when buying the best NVR security system because recorded images or footage consume a lot of space. Modern recorders support large capacity security hard drives, these hard drives are now available in sizes over 12TB which greatly increase your video retention capability.  Make sure to take note of how many hard drives your recorder supports to have a better understanding of the future expandability. 

  • Remote Viewing and Mobile App Support 

Stay connected while away from home by choosing systems that offer access to view footage or live streams remotely. You can manage it via mobile devices such as phones, tablets, and computers. The online software can be accessed through internet network devices and managed portal application platforms. This allows owners to review live shots, making it an ideal means of centrally managing multiple locations, employees, and teams. You also receive increasingly efficient management solutions with remote control capabilities.

  • Motion Detection and Alerts

One feature worth considering before buying is if the cameras have intelligent motion detection. These alert users of the human or vehicle activity immediately, identifying potential dangers, threats, and possible intruders—the reduction of false alarms greatly improves the effectiveness of the alerts! Certain models feature customized settings to flash lights, play pre-recorded messages, or even allow for 2-way communication.

  • Night Vision and Low-Light Performance

For those looking to secure their property during night-time and low-light conditions, night vision is a key consideration. There is an infrared feature equipped with most systems – enabling cameras to capture footage even in pitch-black environments.  A modern invention is the full-time color cameras that can retain color images in low light or even no light using the supplementary white LEDs.  Either of these methods ensure that you can capture relevant footage in all lighting conditions.
