What is the difference between industrial control DVR and embedded DVR, looking forward to professio

The current video recorder is generally divided into two categories, one is the industrial control DVR, and the other is the embedded DVR.

Their composition: Now the so-called industrial control DVR is composed of PC machine plus ** capture card, and the software that matches the ** capture card is installed under Windows, if you need to have a moving point, plus a doctor card can be, now the real industrial control DVR is gone, because his cost is too expensive. Today's industrial computers are PC+ capture cards.

Now the mainstream is the embedded DVR: it is composed of a motherboard built-in capture card chip, a set of hard disk, using Linux system or UNIX system, which can be controlled by the body keyboard, remote control, and mouse. As far as I know now, the industrial control DVR can have up to 36 channels per machine, and the embedded DVR can have up to 16 channels**.

The industrial control DVR can be used like an ordinary computer when recording at the same time.

The embedded DVR can only be used for recording.

To be precise, the industrial control DVR is based on our Windows operating system, adding the most advanced cards, disks and other hardware with professional software to provide the most advanced monitoring of the back-end storage solution. The most common embedded is DVR, which is a device developed for the best business, eliminating the problems of long-term operation and crash of the Windows operating system itself. It is recommended to use an embedded DVR.

The school's surveillance system can use embedded DVR. 1. The difference between embedded and industrial control: (1) Embedded 2) The advantage of industrial control DVR is that it is easy to expand, if you need to add a camera, you only need to add it to the host.

The reason for the high performance of the embedded DVR: from the hardware is mainly reflected in its internal boards are integrated on one or two motherboards, after the integration of the manufacturer in technology, its configuration is lower than that of the PC, and the performance of the operation can be not inferior to the high hardware configuration of the PC; From the software, it is mainly reflected that its system is perfectly combined with the operating system of the DVR, which is a direct call to the hardware, which speeds up the reaction time, improves the running speed, and reduces a lot of unnecessary extra functions to run, and is based on Linux

windows

A DVR on top of the operating system is absolutely impossible.

Stability: The reason for the high stability of the embedded DVR: from the hardware point of view, it is mainly reflected in the fact that all parts are integrated on a motherboard, and the adaptability to harsh environments such as earthquake and dust is good; From the software, it is mainly reflected in the complete combination of its system and the monitoring system of the hard disk video recorder (DVR), which is not easy to be affected by some additional factors, such as the instability of the operating system itself and the undesirable factors caused by the redundant incidental functions. However, there are also some inferior embedded DVRs that have poor stability.

Maintainability: The reason for the low easy maintenance of embedded DVR: mainly reflected in the hardware, embedded due to the high integration, the professional quality of the maintenance personnel is quite high, which is the current national conditions of China, such a talent is too small, a problem basically has to be sent back to the manufacturer for maintenance, the maintenance cost can be imagined, especially after the warranty period. And this process is less than a week, more than a month or two, which causes serious inner disgust to customers to use and buy next time, and also brings a lot of trouble to many engineering companies, and even customer loss; In terms of software, embedded software basically does not require maintenance, and its software maintenance cost is much lower than that of monitoring systems based on Windows and Linux operating systems.

Antiviral. The reason for the high anti-virus performance of the embedded DVR: mainly because its hardware and software are dedicated, the data stored by the chip is read-only, not writable, and the incidental functions of the software are very few, therefore, the virus has no way to start.

Monitoring: monitoring function is one of the most important functions of embedded hard disk recorder, whether real-time, clear monitoring camera picture, this is a core problem of the monitoring system, most of the embedded hard disk recorder can do real-time, clear monitoring;

Video: the video effect is the core and vitality of the digital host, in the monitor to see the real-time and clear image, the recording and playback effect is not necessarily good, and the most important thing to see the forensic effect is to see the video effect, in general, the video effect is more important than the surveillance effect. Most DVR recordings can achieve real-time 25 frames of second recording, some of the total resources of video recorders are less than 5 frames of seconds, usually the resolution is CIF or 4CIF, 1 channel camera recording 1 hour about 180MB 1GB hard disk space;

Alarm function: mainly refers to the input alarm of the detector and the alarm of the image ** frame measurement, after the alarm, the system will automatically turn on the video function, and turn on the corresponding spotlight, alarm and network output signal through the alarm output function. Image motion detection is the main alarm function of DVR;

Control function: It mainly refers to the control of the all-round camera PTZ and lens through the host, which is generally completed through a special decoder and keyboard;

Network function: through the LAN or WAN through simple identification, the host can carry out various monitoring and recording control operations, which is equivalent to local operation;

Password authorization function: In order to reduce the failure rate of the system and illegal access, password passwords are required for programs such as stopping recording, arming and disarming the system and entering programming, so that unauthorized persons are not allowed to operate, and are generally divided into multi-level password authorization systems;

Work schedule: can be programmed to a certain period of time of a camera, which is also a unique function of the digital host, it can pre-arrange all the changes in the holidays and work and rest schedule into the program, and can realize unattended in a certain sense.

The main difference between industrial control and embedded video recorders.

1. The industrial computer uses the x86 architecture, and the embedded computer uses the RISC architecture. Mammoth liquid.

2. The industrial computer uses the Windows system, and the embedded computer uses the Linux system.

Industrial control DVR (PC-based

DVR) is based on the industrial computer as the hardware, the Windows operating system as the basic software, equipped with the video and audio compression board, with the help of professional compression algorithms and PC software and hardware capabilities to record and play back the video and audio signals of the monitoring ruler material control system. The core device of industrial control DVR is the video and audio compression card.

Embedded video recorders are hardware platforms such as ARM and DSP and dedicated embedded operating systems such as VXWORK, PSOS

It's just that one is a widely used solution designed by Intel, and the other is a dedicated solution designed by itself.

DVR, which can be said to be a computer for a day. Server + capture card + capture software, generally industrial computer chassis + server motherboard + disk array, embedded only embedded system The current popular embedded system kernel is generally Linux.

Hello! DVR is roughly divided into two categories, DVR (computer + capture card) 2Embedded DVR.
