We are in an era where security has become highly affordable and reasonable. With home surveillance systems, you can easily monitor your home and office remotely and take action at the slightest sign of breaking. A wide range of home security surveillance systems includes IP cameras, Fire and smoke detectors and Network Video recorders (NVR)

Most of us already know what IP Camera systems and smoke detectors systems are - one is a surveillance camera system, and another is used to detect smoke. But what is NVR, and how to choose a network video recorder? 

Here we will be talking about what Network Video Recorders are and how do we choose them. 

What is Network Video Recorder?

Source: Dahua Network Video Recorder is a specialized video surveillance system device that records videos within a network on a hard disk drive. Network video recorders do not capture devices; rather, the NVR monitors, processes, and stores the videos from IP Camera systems and CCTV Cameras. 

This is a simple definition, and from this simple definition, you can already guess why Network Video Recorders (NVR) are an essential aspect of any Video surveillance system. Without NVR, you cannot store video and watch it at a later date. 

The storage capacity and the storage quality of video stored in a Network Video Recorder (NVR) will vary a lot depending on the brand and model of the device. 

With this, we have covered a general gist of what the NVR system is. And now, let's jump to the main topic  -

How to choose the best Network Video Recorder for you?

There are a ton of Network video recorders in the market. Firstly you have a decent number of brands that you need to filter out. Then, from the brands that you have selected, you will need to filter out the specific products from within the brands. This can undoubtedly make the process of selecting the perfect NVR tedious. 

However, there are a few criteria that you can use to make this process easier. The criteria are as follows.

1) Number of Channels

With the exception of a few ultra-specific NVRs with only single input, these devices generally have multiple input channels. These channels send video signals from IP cameras and or Network CCTV camera systems. The number of input channels you require may vary depending on where you install the security video surveillance. At Nirvana Mala, one of the best wholesalers and distributors of beaded wrist mala bracelets in Nepal, you can buy the best Inlaid Brass Lotus Seed Wrist Mala Bracelets at the best price and at your convenience.

The recommended number of input channels is eight channels for general household and small organizational use, 16 to 32 channel NVR for mid to large organizations, and above 32 channels for large organizations.

Now, some may be wondering, "why does video resolution matter if the video recorder cannot record videos?" You will be justified to think so. But although a video recorder does not record videos, it needs to have the capacity to support videos from IP and CCTV cameras. If your NVR system does not support high-resolution videos, but your surveillance camera is HD videos, your overall security and surveillance will fail. 

2) Video Resolutions

Choosing Network Video Recorder based on Video resolution will depend on your video surveillance camera. The generally accepted resolutions for IP cameras and CCTV cameras are 5MP to 8MP for regular usage and 8MP to above 4K display for organizational use. As such, your network video recorders must also correspond with these video resolutions for the overall security system to run smoothly. 

Side note: If you want the best TP CCTV cameras then Dahua and Hikvision are among the best choices for you. To make things clearer, we have an article that can aid you in choosing the best CCTV camera between Dahua and Hikvison .

3) Storage Capacity

This feature is undoubtedly one of the most important aspects of choosing the best Network Video Recorder for you. The storage capacity of this device indirectly affects the video resolution. This is because if you choose a Vide Recorder with less storage capacity and then opt for 4K video resolution, then you will constantly need to review and refresh the storage for additional video recording. 

The storage of NVR ranges from 6GB of storage that is compatible only with Low Resolution to 10TB that supports 4K ultra HD video formats. Depending on storage capacity, the refresh duration can range from weekly to monthly.

Therefore, if you are thinking about "How to choose the best Network Video Recorder?" then checking the storage capacity of NVR system is a good way to determine the perfect one for you. 

4) Management and Playback Options

With advancing technology, device management should be easy and intuitive. Therefore you can filter the Network Video Recorders by looking at their management and playback options. The best NVR comes with easy and intuitive management systems along with easy playbacks. 

The management systems can include features such as alarm and notification manager, e-mail notifications, smartphone connectivity, etc. Although secondary, these features can make your life a lot easier.

5) Connectivity

As Network Video Recorders are connected to IP cameras and Network Cameras, having good connectivity is undoubtedly one of the most important aspects when choosing an NVR. You should always choose the video recorder with multiple forms of connection ports and a video management system along with versatile connection ports. 

In addition to the ports, there are also Network Video Recorders with WiFi connectivity. So if you can, always choose the one with multiple connection ports and wireless connectivities. 

6) Price

This goes without saying that you should stay within your budget when purchasing network video recorders. Although installing one will provide you with enhanced security, it will all be for nought if you exceed your budget. NVR system cannot protect you from overspending. And let us remind you that you can always upgrade the device later. 

So always keep your budget in your mind before you choose the Network Video Recorders.
