What is the difference between nvr and hvr?

If you ask if there is any difference between nvr and hvr, can you answer it? This article will focus on introducing you. In the monitoring system, we use DVR, NVR and HVR three kinds of DVRs when storing videos. However, what are the three DVRs? What are the differences? Let's briefly introduce them:

What is the difference between nvr and hvr?

DVR is a hard disk recorder. Compared with the traditional analog video recorder, it uses hard disk video recording, so it is often called DVR, also known as DVR. It is a computer system for image storage processing, with long-term recording, recording, remote monitoring and control of images/voices.

The NVR is a network hard disk recorder. The main function of the NVR is to receive the digital video code stream transmitted by the IPC (network camera) device through the network, and store and manage it, thereby realizing the distributed architecture advantage brought by the network. Simply put, with NVR, you can simultaneously view, browse, play back, manage, and store multiple webcams. Get rid of the computer hardware, no longer need to face the tedious installation software. If all cameras are networked, then the only way to do this is to have a centralized management core.

HVR is a high-definition hybrid digital hard disk recorder, embedded Linux operating system software architecture, and uses a high-performance DSP processor as a hardware platform. It is a high-definition network hard disk video surveillance device that simultaneously simulates BNC and digital network RJ45 standard interface, and supports analog front-end video capture and encoding, network front-end HD access, and decoding storage.

The difference between DVR, NVR and HVR is that the front end of the DVR product is an analog camera, which can be regarded as a digital coded storage device for analog video, and the front end of the NVR product can be a network camera (IPCamera) and a video server (video encoder). ), DVR (code storage), the device type is more abundant. The HVR front-end device is a hybrid of a network hard disk camera and an analog camera, and has the functions of a DVR and an NVR.
