The traditional difference between digital DVRs

Hard disk video recorder (digitalvideorecorder, DVR), that is, digital video recorder, compared with the traditional analog video recorder, uses hard disk recording, so it is often called hard disk recorder, also known as DVR. It is a set of computer systems for image storage processing, with the function of long-term video recording, recording, remote monitoring and control of image voice, DVR integrates five functions such as video recorder, screen splitter, PTZ lens control, alarm control, network transmission, etc., with a device can replace the function of a large number of equipment in the analog monitoring system, and gradually occupies an advantage in the first place.

DVR uses digital recording technology, in image processing, image storage, retrieval, backup, as well as network transmission, remote control, etc., it is far superior to analog monitoring equipment, DVR represents the development direction of TV monitoring system, M-JPEG, and MPEG-4, is the most common compression method in China; There are two kinds of soft compression and hard compression from the compression card, and the soft pressure is greatly affected by the CPU, and most of them cannot do full real-time display and recording, so it is gradually compressed and eliminated; From the number of camera input channels, it is divided into 1 channel, 2 channels, 4 channels, 6 channels, 9 channels, 12 channels, 16 channels, 32 channels, and even more channels;

In general, according to the system structure, it can be divided into two categories: PC-based DVR based on PC architecture and embedded DVR independent of PC architecture. Here we will mainly talk about PC DVR and embedded DVR.

Embedded system generally refers to a non-PC system, a device or equipment that has computer functions but is not called a computer. It is an application-centric, software and hardware can be reduced, and has strict requirements for function, reliability, cost, volume, power consumption, etc.

To put it simply, the embedded system integrates the application software and hardware of the system, similar to the working mode of BIOS in the PC, with the characteristics of small software, high automation, fast response speed, etc., especially suitable for applications that require real-time and multi-tasking. Embedded DVR is an embedded system based on embedded processor and embedded real-time operating system, which uses a special chip to compress and decompress the image, and the embedded operating system is mainly to complete the control and management of the whole machine. This kind of product does not have as many modules and redundant software functions as PCDVR, and the stability of software and hardware has been planned in the design and manufacturing, so the quality of such products is stable, there will be no crash problem, and the storage speed, resolution and image quality of the video and audio compression stream have been greatly improved, and the function is not inferior to PCDVR.

The embedded DVR system is built on an integrated hardware structure, and the entire video and audio compression, display, network and other functions can be realized through a single board, which greatly improves the reliability and stability of the entire system hardware. The main functions of DVR include: monitoring function, recording function, playback function, alarm function, control function, network function, password authorization function and work schedule function, etc.

The most essential difference is that one is a digital signal and the other is an analog signal.

They can both provide high-quality recording and storage, and can provide higher recording quality and longer recording time. When a problem occurs, the following steps can be taken to fix it:1

First of all, check if the power supply of the recorder is normal and make sure the power supply is normal. 2.Check whether the cable of the recorder is normal and make sure that the cable is normal.

3.Check if the settings of the recorder are correct and make sure the settings are correct. 4.

Check whether the hardware of the recorder is normal and make sure the hardware is normal. 5.If the above steps don't solve the problem, you can try to reinstall the software of the video recorder to make sure the software is working properly.

The above are the steps to solve the problem of analog DVR and digital DVR. A personal tip is that before using the recorder, you should check the power supply, cables, settings and hardware of the recorder to make sure that the recorder is working properly.

Analog DVR? Sounds weird! All you store on your hard drive is digital information!

As far as I know, analog video recorders use cassette as the storage medium, and digital video recorders use hard disks as storage media. If you compare it, it's like comparing *** with a cassette machine! Analog video recorders are few and far between!

One is video recording, the other is storage computing, and that's the fundamental difference, not a thing.
