Choosing the Right Network Video Recorder for Small Businesses: Key Considerations


With the increasing importance of video surveillance in small businesses, choosing the right network video recorder (NVR) has become crucial. An NVR not only allows businesses to store and manage their surveillance footage but also provides advanced features for enhanced security and monitoring capabilities. But with so many options available on the market, it can be overwhelming for small business owners to select the most suitable NVR for their specific needs. In this article, we will explore the key considerations that small businesses should keep in mind when choosing an NVR.

Understanding Network Video Recorders

Before diving into the considerations, let's first understand what an NVR is and how it differs from a digital video recorder (DVR). While both NVRs and DVRs are used for video surveillance, they have distinct differences in terms of technology and functionality.

An NVR is a specialized computer system that records and stores video footage from IP cameras or network cameras. It uses a network connection to receive the video streams directly from the cameras, making it highly flexible and scalable. On the other hand, a DVR is an older technology that processes and records video footage from analog cameras. It uses coaxial cables to connect to the cameras, which limits its scalability and versatility.

With a clear understanding of NVRs, let's explore the key considerations that small businesses should take into account when choosing the right one for their needs.

Evaluating Storage Requirements

One of the primary considerations for choosing an NVR is evaluating your storage requirements. The amount of storage you need will depend on factors such as the number of cameras, the desired video resolution, and the duration for which you want to retain the footage.

To calculate the required storage capacity, you can use the formula:

Storage Capacity = (Bitrate per camera x number of hours of footage per day x number of days of retention) / 8

For example, if you have four cameras with a bitrate of 4 Mbps, you want to retain footage for ten days, and each camera records 8 hours of footage per day, the required storage capacity would be:

(4 Mbps x 8 hours x 10 days) / 8 = 1600 megabytes or 1.6 terabytes

By accurately estimating your storage requirements, you can ensure that the NVR you choose can accommodate your surveillance needs without the risk of running out of storage space.

Consider the Number of Camera Inputs

Another crucial consideration is the number of camera inputs supported by the NVR. Small businesses typically have a limited number of cameras, but it's essential to choose an NVR that can support future expansion if needed.

NVRs come with a specific number of channels, indicating the maximum number of cameras they can accommodate. For example, an 8-channel NVR can support up to 8 cameras, whereas a 16-channel NVR can accommodate up to 16 cameras. It's always wise to choose an NVR with more channels than your current requirements to allow for future growth and scalability.

Ensure Compatibility with Your Cameras

Compatibility is another critical factor to consider when selecting an NVR. Not all NVRs are compatible with all types of IP cameras or network cameras. Therefore, it's crucial to ensure that the NVR you choose supports the specific camera models you have or plan to install.

To ensure compatibility, you should check the NVR manufacturer's website or consult with a security professional. They can help you determine if the NVR is compatible with your existing cameras or suggest compatible camera options if you are starting from scratch.

Look for Remote Monitoring and Mobile Access

In today's increasingly connected world, remote monitoring and mobile access have become essential features for small businesses. The ability to access live or recorded surveillance footage from anywhere at any time adds an extra layer of convenience and security.

When choosing an NVR, make sure to look for models that offer remote monitoring capabilities. This allows you to access the NVR's user interface through an internet browser or a dedicated mobile app. With remote access, you can keep an eye on your business premises even when you're away, improving the overall security and peace of mind.

The Importance of Video Analytics

Video analytics is an advanced feature that offers various tools to enhance surveillance monitoring and overall security. While not all small businesses may need video analytics, it's worth considering if you require specific capabilities such as motion detection, object tracking, or people counting.

Video analytics uses algorithms to analyze video footage in real-time, allowing for proactive alerts and automatic responses to specific events. For example, if a person enters a restricted area, the NVR can trigger an alert or send a notification to the business owner. Depending on your business requirements, video analytics can significantly improve your surveillance capabilities and reduce the need for constant manual monitoring.


Choosing the right network video recorder for your small business requires thoughtful consideration of various factors. To ensure that you make the best decision, evaluate your storage requirements, consider the number of camera inputs, ensure compatibility with your cameras, look for remote monitoring and mobile access features, and explore the advantages of video analytics. By carefully considering these key factors, you can select an NVR that meets your specific needs and provides a solid foundation for your video surveillance system. Remember, investing in the right NVR is an investment in the security and safety of your business premises.
