Having a dependable CCTV system will ensure your business has a good level of security whether you own an office, retail store, warehouse, hotel or commercial property. Choosing the right video surveillance system will help you to effectively monitor your premises.

Many businesses use Network Video Recorders (NVR) and Digital Video Recorders (DVR). Whilst both systems can record and store CCTV footage there are several differences between the two.

Understanding the differences will help your business invest in the right security. Here are 7 Key Differences Between NVR and DVR systems.

1. Camera Connections

The key difference between NVR and DVR systems is how cameras connect to the system.

DVR systems typically use Analogue CCTV cameras. The cameras then send the video signal through coaxial cabling to the DVR.

NVR systems typically use IP (Internet Protocol) cameras. These cameras take the video signal and process it digitally and then send the video through a network connection. This is typically done through Ethernet cables.

This difference will help if you are installing a new CCTV system.

2. Video Quality

Having good quality video will help you identify people, monitor activity, and review any incidents.

Traditional DVR systems will use Analogue cameras. However, there are HD over Coax technologies which can provide high quality video.

NVR systems will typically have higher quality cameras available such as Full HD or 4K IP cameras.

Choosing the right camera resolution will help businesses in Dubai monitor entry points, reception areas, parking areas and larger commercial properties.

3. Installation

Depending on what system you choose can increase the overall cost of your CCTV.

DVR systems typically use coaxial cabling to connect the cameras to the recorder. You may need extra power setups.

NVR systems typically use Ethernet cabling. If you use Power over Ethernet then you can use compatible cameras to power the camera and send the data over one cable.

This makes installation easier and reduces the amount of cabling required. This is ideal for offices and commercial properties.

4. Flexibility

As a business grows they might need to add extra cameras, departments and new security requirements.

DVR systems can add extra cameras however it depends on how many channels, cabling and recorder are available.

NVR systems typically have more flexibility to add extra cameras. As it uses IP cameras it will depend on how much network space and recorder you have.

If you are a growing business in Dubai then this is an important factor to consider.

5. Remote Access

Many businesses today need to remotely monitor their premises.

Both systems can be remotely accessed using the right applications. However,

NVR systems can be easily integrated into an IP based network. If you want a flexible network based system then this is a great choice.

Always use strong passwords and ensure the system is properly secured.

6. Storage Requirements

The amount of storage needed will depend on how high quality your cameras are, how often you want to record, frame rate, compression and how many cameras you have.

DVR systems typically use internal hard drives to store the recorded footage. This will depend on how much storage the recorder has.

NVR systems can also use internal or compatible external storage. Some systems can also offer additional network based storage.

You should plan how many days you will need to store the footage and make sure you have enough storage.

7. Cost

The cost of the system can also be a key factor.

DVR systems can be a good choice if you have compatible Analogue cameras and coaxial cabling. Using what you already have can help keep costs down for installation.

NVR systems can be more costly to install as you will need IP cameras, however they can be more flexible for a growing business.

Depending on your existing infrastructure, security requirements, complexity of installation and ongoing maintenance.

Should Your Business Use NVR or DVR Systems?

There isn’t a one size fits all solution.

A DVR system could be a good choice if you already have Analogue cameras and want an easy upgrade. An NVR system could be a better choice if you want to install new cameras using IP cameras, higher quality recordings and flexible network connections.

Consider:

How large your premises are.

How many cameras you need.

What quality of video you need.

What cabling you have.

Do you need to remotely view the cameras?

How much storage do you need?

Will you be expanding?

A professional survey can help you decide on the best system for your business.
