Network IP Video Recorder NVR

Main functions and purpose of network video recorders

IP video recorders (NVRs) are the central elements of a digital video surveillance system. These are video recorders for IP cameras that receive, process video signals and store information recorded by cameras. A network IP video recorder operates via a local network or the Internet, providing remote access to data. The main purpose of NVR is to coordinate video streams from several cameras to one device for viewing and recording.

First of all, a network video recorder performs several key functions:

  • recording and storing video on a hard drive;
  • displaying and playing the video stream on a monitor screen or via a web interface;
  • remote access from anywhere in the world;
  • integration with other systems and security tools.

Network IP video recorders are the “brain” of a video surveillance system, as the maximum number of cameras in the system, recording quality, and archive depth depend on their capabilities.

Benefits of using IP recorders

Modern IP video recorders (NVRs) have a number of advantages over analog video recorders (DVRs). A digital system based on a network recorder provides flexibility, high quality, and easy access to video data. Below are the main advantages that encourage more and more users of network video recorders to switch to IP solutions:

  • easy installation and connection;
  • real-time remote access;
  • high recording quality;
  • scalability and flexibility.

Each of these advantages makes IP video recorders the best choice for modern security systems.

How to choose an IP video recorder

The choice of a network recorder depends on your needs and the specifics of the facility. Before you buy an IP video recorder, you should analyze several important criteria to ensure that the device fully meets the tasks at hand. Below are the main parameters to consider when choosing an NVR:

  1. Number of channels (cameras). Recorders can be different in terms of the number of channels: from 4, 8, 16 to 32, 64 and even more.
  2. Recording resolution. If it is critical to recognize faces or license plates, choose a dash cam that supports 4K (8 megapixels) or more. If basic monitoring of the situation is enough, 2-4 megapixels will do.
  3. Capacity and number of drives. If you plan to store your archive for a long period of time (a week, a month, or more), you'll need a capacious HDD or several. For example, compact 4-channel models are usually designed for 1 disk (6-8 TB), while 16-channel models can accommodate 2 disks, and 32-channel models can accommodate 4 or more.
  4. Method of connecting cameras (PoE or not). Some IP video recorders are equipped with a built-in PoE switch, which allows you to directly connect IP cameras and power them via Ethernet. Other models require a separate PoE switch or injector to power the cameras.
  5. Additional features and interfaces. Modern NVRs can have video analytics functions: motion detection, line crossing, face or license plate recognition.
  6. Budget. Estimate how much you are willing to invest in a video surveillance system. Remember that the price of IP video recorders depends on the performance and functionality of the device.

To make your choice easier, below is a table comparing the characteristics of several popular models available on Kobi.ua. These are examples of 4-, 16-, and 32-channel network recorders from the ZetPro brand that demonstrate the difference in capabilities:

Specifications ZetPro ZIP-NVR301-04L6TB-P4 (4 channels, PoE) ZetPro ZIP-NVR302-16S (16 channels) ZetPro ZIP-NVR304-32E-B (32 channels)
Max. resolution 8 Mp per channel 8 Mp per channel 12 Mp per channel
PoE ports for cameras 4×PoE (built-in) (requires a separate PoE switch) (requires a separate PoE switch)
HDD support 1×SATA, up to 6 TB 2×SATA, up to 8 TB 4×SATA, up to 4×8 TB
Smart features Motion detection, alerts Smart VCA (intrusion, face, line, etc.) Face and license plate recognition, advanced VCA
ONVIF compatibility Profile S/G/T Profile S/G/C/Q/A/T Profile S/G/C/Q/A/T
Video outputs HDMI (4K) + VGA HDMI, VGA 2×HDMI (1–4K), 1 × VGA

The smaller 4-channel model is suitable for a small system with several cameras. The 16-channel NVR is a universal solution for a medium-sized company, with basic smart analytics functions and support for two hard disks. The flagship 32-channel NVR is designed for large professional systems.
