NVR – Network Video Recorder

A network video recorder is a complete Internet Protocol camera recording system and is mostly used in Internet Protocol video surveillance systems. It records security video surveillance footage in digital format to a hard drive. It does not use any dedicated hardware for video capture but makes use of special software on a dedicated device. Also, can record as well as access recorder images and live views. Typically, video is processed and encoded from the surveillance IP or CCTV camera and then moved to the NVR for storage through an Ethernet or Wi-Fi network.

Some of the NVR features include:

• Video analytics
• Recording mode options
• Power-over-Ethernet (PoE) network ports
• PTZ camera controls
• Remote configuration
• Recording triggers
• Video compression schemas

Types of NVR Available

• 4 Channel

A four-channel Network Video Recorder will have four different video inputs and will support the connection of up to four security cameras and have the functionality to be able to display all the images on one screen. They are ideally suitable for small business applications and residential settings with a limited number of cameras and reliable local storage for backup and evidence purposes.

• 8 channel

The eight-channel NVRs support recording of up to 8 network cameras simultaneously, with resolutions up to 5 megapixels. This is a flexible option to suit your various monitoring needs.

• 16 channel

A 16-channel NVR will allow you to have 16 cameras on one system and can record 16 cameras on one system. The number of cameras has to be equal to or less than that supported by NVR.

Frequently Asked Questions

1. 1. What Does NVR Stand for?
      The term NVR stands for Network Video Recorder. In an NVR system, video is captured with digital, or Internet Protocol cameras. It directly processes video from the camera itself. The processed stream is then transferred to the recorder through an Ethernet cable.
   2. How do I set up a network video recorder?
      Steps to connect NVR for IP camera with a PoE port
      • Take the Ethernet cable from the router and connect it to the back of the NVR. Ensure that NVR is connected to the network.
      • Use Ethernet cables to connect the IP cameras to PoE NVR. As the NVR is enabled with the PoE technology, it can easily power the IP cameras.
      • Take an HDMI cable or a VGA cable to connect NVR and TV or monitor. Ensure that you use the right input to connect the TV or the monitor— HDMI 1, HDMI 2, or VGA etc.

      Steps to connect NVR for IP camera without a PoE switch:

      • Take an Ethernet cable to connect the LAN port on the external PoE switch and the router. Then connect the router with the non-PoE NVR.
      • Use Ethernet cables to connect all IP cameras to the PoE switch RJ45 ports. The PoE switch will deliver power as well as support data transmission.
      • Use an HDMI cable or VGA cable to connect the monitor and the NVR. Always use the right input for making the connection.
   3. Can NVR Access Remotely?
      NVRs come with a built-in network capability that can be accessed over the internet remotely or outside your home network on a computer, desktop video surveillance software, mobile apps, or web browsers.
   4. Difference between NVR and DVR?
      Essentially, both NVR and DVR systems are liable for video recording. But, they vary in how they record the footage. A DVR transforms analog footage into a digital format, while an NVR generally only works with digital footage. DVR systems process data at the recorder, while NVR systems encode and process data at the camera before transmitting it to the recorder for storage and remote viewing. Both systems manage data differently. Therefore, they need different types of cameras. Most of the DVRs are used with analog cameras, while NVRs are used with IP cameras. Most notably, a DVR-based surveillance system is a wired security system wherein an NVR system can be a wired or wireless system.
   5. Can NVR work without the internet?
      An IP camera system will work absolutely fine without an internet connection. One can view the cameras, record to a hard drive, and search through recorded footage using just a monitor and a mouse plugged directly into the NVR.
