WHY YOU NEED AN NVR (NETWORK VIDEO RECORDER) FOR YOUR BUSINESS IN 2021

At the beginning of a business calendar year, the organizational need for a video surveillance system is afoot, you will need to choose between the following

1) NVR (NETWORK VIDEO(VIRTUAL) RECORDER) SYSTEMS
2) DVR (DIGITAL VIDEO RECORDER) SYSTEMS

our technical team would advise:  If you’re building your security camera system from scratch, choose an NVR system. NVR systems rely on newer, more advanced technology and therefore offer higher image/video quality (among other benefits). They both share similar functions executing their primary functions of recording videos, what differentiates them is how they record videos.

1.  NVR SYSTEMS – This system records and stores virtual data directly from the network it lives on. this system works with a more advanced surveillance camera. e.g IP CAMERA – INTERNET PROTOCOL. an IP is an identifying CODE that is associated with a specific computer system or computer network. when connected to a computer system, the i.p allows the system or network to send and receive information.
note: An NVR can serve as a HUB in the above description.

DVR SYSTEMS

DVR stands for Digital Video Recorder. These systems are considered the older “legacy” option. Unlike an NVR system, DVR systems work with analog cameras, which can’t process video footage. Instead, the analog cameras stream raw video footage to recorders via coaxial cables. From there, the recorder processes the video footage. Once the video is processed, both DVR and NVR systems work the same. After connecting to a smartphone or any other viewing device, you can easily access and view your video footage as needed.

Now that we know the difference between how NVR and DVR systems works, let’s look at what those differences mean in terms of the pros and cons of each system.

NVR Surveillance System: Pros & cons

Pros Cons
Can record video and audio; DVR only records video Cost, typically NVR systems are more expensive
Better image quality The software can be harder to use
More system flexibility
Better coverage, 1 camera has multiple lenses
Can be wired or wireless; DVR cannot be wireless
Only needs 1 cable for video, audio, and power
Can be used to identify faces, license plates, etc. due to higher image quality

DVR Surveillance System: Pros & Cons

Pros Cons
Less expensive than NVR systems Lower frame rates and lower image quality than NVR systems
Simplicity, easier to set up and operate than NVR systems Requires extra cables and wires, more complex installation process
Image quality is improving (for systems using HD over Coaxial technology) Separate power source required
Less coverage, it takes multiple analog cameras to cover the same area as 1 IP camera
Only good for observing, can’t record audio
