The difference between embedded DVR and industrial DVR
Currently on the market from the combination of DVR (including hardware architecture and software types) points, there are three main products, 1 is a pure embedded hard disk recorder (hardware, software integrated together); 2 is an industrial hard disk video recorder type hard disk recorder (Hardware and software are completely separate, and the monitoring system is still based on a certain operating system (eg: Windows 98/2000/XP Linux)); 3 industrial hard disk recorders embedded hard disk recorders (hardware, software is separate, but monitoring The system is not based on a certain operating system, but the kernel of an operating system is extracted and integrated perfectly with the monitoring system and run as embedded software.) This article compares these three DVRs in terms of price, performance, stability, ease of maintenance, incidental functions, and anti-virus.
Analysis of comparative results:
The reason for the high price of embedded hard disk recorders is mainly reflected in the fact that their technical content will be higher than that of industrial-control hard disk recorders, and the cost of the investment in the early stage is high, and the companies that can intervene are harder and less effective than the industrial hard disk recorders. The reason that this also causes another high price is that because of the small number of companies involved, the transparency and competition of the hardware prices used by them are not high enough.
The reason for the low price of industrial control DVRs is mainly due to the fierce competition and high transparency of their hardware devices. Many of them are assembled by system integrators or engineering companies themselves, which saves a lot of brand costs and other additional expenses. Another very important reason is because Windows (except for the Linux operating system, which is generally available at 50 yuan for genuine and free versions) is pirating, but the advantages of this Windows version of DVR are now being hit with Microsoft in China. Piracy is slowly deteriorating.
The reason for the high price of the embedded hard disk video recorders for industrial control hard disk video recorders is mainly reflected in the fierce competition and high transparency of their hardware equipment. Many of them are system integrators or engineering companies to assemble themselves, which saves a lot of brand costs and other additional expenses ( This is the same as that of industrial-control hard disk recorder-type hard disk recorders, and the embedded monitoring software requires less hardware than the monitoring software based on the operating system. Software, because its technical content is higher than the monitoring system based on a certain operating system, the price is relatively high. However, when the hardware (in the case of the same channel number and the same acquisition card) is combined with the software, the overall price is basically the same as the price of an industrial hard disk video recorder hard disk recorder (if the Windows DVR is not the price of the Windows operating system).
performance:
The reason for the high performance of embedded hard disk video recorders: from the hardware is mainly reflected in the internal board cards are integrated in one or two boards, after the production of the home in the technical integration, its configuration than the industrial control hard disk video recorders to Low, but the performance of the operation can be compared with its high hardware configuration industrial control hard disk recorder machine is not inferior; from the software is mainly reflected in the system and the hard disk recorder operating system perfect combination, is directly to the hardware The call speeds up the reaction time, increases the speed of operation, and reduces many unnecessary additional functions. On the other hand, hard disk video recorders based on Linux and Windows operating systems are absolutely impossible.
The reason for the low performance of industrial-control DVR-type hard disk recorders is that they are self-assembled from the hardware, and their technology integration is not high enough. There are also some system integrators and contractors who do not have much strength in this regard. They do not know enough about hardware knowledge and the combination of hardware and software, resulting in improper collocation of some high and low configurations, which is also a very important reason. . However, the current hardware performance is already very high, and the development is very rapid, which is not enough to affect the performance of the industrial hard disk video recorder DVR, but the cost is reduced; from the software is mainly reflected in its above is based on Windows and Linux operating system There are many functions that are not required for the monitoring system. This not only has many redundant functions, but also affects the operating speed or causes the instability of the monitoring system.
The reasons for the performance of the industrial hard disk video recorder embedded hard disk video recorder are centered: the hardware embodiment is basically the same as that of the industrial hard disk video recorder type hard disk video recorder. But in software it is a direct call to some hardware and removes most of the operating system's redundancy (for monitoring systems) functionality. Solid industrial control DVR embedded hard disk video recorder to industrial hard disk video recorder type hard disk video recorder performance is higher.
stability:
The reason for the high stability of the embedded DVR is that the hardware is mainly embodied in that all parts are integrated on one main board, and the adaptability to the harsh environment such as shock and dust is better; the software is mainly embodied in the system and the DVR. The monitoring system of the (DVR) is completely integrated and is not easily affected by some additional factors, such as the inherent instability of the operating system and the adverse factors caused by the redundant incidental functions. However, there are some poor quality embedded DVRs that have poor stability.
The reason for the low stability of the industrial DVR DVR is that it is mainly embodied in the hardware that all parts are linked together by a card, and the adaptability to the harsh environment is not good enough. This is an industrial control DVR since the machine Common problems, but with the development of the current hardware technology, this has greatly improved compared to previous years. In this regard, the gap between embedded hard disk recorders has become less and less; from the software is mainly reflected in the operating system (Windows, In terms of the stability of Linux itself, Linux is more stable than Windows.
The reason for the stability of the embedded hard disk video recorder of the industrial control DVR is that the hardware is the same as the hardware of the industrial DVR DVR. However, the software is not based on an operating system, so it can eliminate the operation itself. The effect of instability. With high technical content, the general enterprise does not have this ability to enter, and it also provides another guarantee for the stability of the industrial hard disk video recorder embedded hard disk recorder monitoring system.
Easy to maintain:
The reason for the low ease of maintenance of embedded DVRs is that they are mainly embodied in the hardware. Because of the high integration level of embedded users, the professional quality of maintenance personnel is very high. This is too much for China’s national conditions. Small, a problem basically has to be sent back to the manufacturer for repairs. The cost of maintenance can be imagined, especially the warranty period. This process lasts for a week or as long as a month or two. This creates serious feelings of dissatisfaction for the customer and the next purchase. It also brings a lot of trouble to the engineering company and even the loss of customers. In terms of the above, 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.
The reason for the ease of maintenance of industrial DVR DVRs is that they are mainly embodied in hardware. Because industrial DVRs can be self-assembled, their hardware can be purchased everywhere, and the contractor will have some backup. In addition, the professional quality requirements of maintenance personnel are also high, so that even if the industrial hard disk recorder hardware problems can be solved quickly; from the software is mainly reflected in the Windows and Linux systems are too complex, more redundant functions to maintain efficiency, But the most important thing is that reinstalling a system can completely solve it, which is much faster and more convenient than sending an embedded hard disk recorder back to the manufacturer.
The reason for the high maintainability of the industrial hard disk video recorder embedded hard disk video recorder is the same as that of the industrial hard disk video recorder type hard disk video recorder, and the embedded software is basically the same as the software of the embedded hard disk video recorder and can be considered as not requiring maintenance. Its easy maintenance is the highest, most convenient, and the lowest cost.
Antiviral:
The reason for the high anti-virus performance of the embedded hard disk recorder is mainly because its hardware and software are all dedicated. The data stored on the chip is read-only and cannot be written, and the software has very few incidental functions. Therefore, the virus has no way to start.
