Rapid Development of Video Recorder
Video recorder gets increasingly wide applications, video coding technology develops rapidly and the features of product tend to be more diverse. The rapid development of embedded real-time operating system and the software is embedded in flash which cannot be modified with characteristics of simple and compact structure, small size and others and it pursues a more professional and practical mobile digital video recorder. With the matures of video and audio encoding technology, the constant improvement of the product features and application fields are continue to broadened, the market demand for embedded DVR is growing at high speed. And with the entrance of enterprises with a strong technical and financial strength, it is bound to further promote the development of embedded DVR market.
Current Situation of DVR
The number of company who has its own R & D capability on embedded DVR is rare. Technical threshold: the development of DSP, embedded real-time operating system and network development. Generally dvr manufacturer has not capabilities on low-rise development, while the application of foreign programs is limited by the original proposal resulting in the shortage of flexibility which is unable to meet the diverse needs of customers. And the other is capital threshold: the purchase of the development environment, the establishment of the development team, the investment of development capital and the shortage of developing talent. Furthermore, some are lack of network functions, and some network functions are not strong.
Routine Maintenance of DVR
First, Place the recorders in the cooling ventilation occasions with good air circulation and heat dissipation while it should not be placed in direct sunlight or near heating appliances. Because the life of electronic devices in recorders will be greatly reduced at high temperatures, or even damaged, recorder's shell vents should not be blocked, the cover must be removed when it is started. Second, the environment with damp or wet corrosive gas is taboo for the use of the DVR, moist environment causes inside metal parts corrosion, and even worse, it may block the machine transmission parts, or causes electronic device leakage, short circuit, and even electrical breakdown. Latest recorders with condensation protection device will automatically shut down when the interior is too wet. And do not make it work in a gas, smoke environment. Third, the case of DVR should be wiped by clean soft cloth. Recorders should stay away from the magnetic field, or it will interfere with its normal work, and the magnetization of internal parts. It is better to stay away from the speaker, induction cooker, magnet toy and electronic table.

DVR Recorder Development in China
The Rise of China Security DVR Recorder
Ever since the 1980s, the foreign analogy monitoring system grabbed a large piece of China mainland market share. During the 20 years, the monitoring system in China markets are almost foreign brands and products, although there are a number of national enterprises to participate in this competition in the industry, but they has no chance to become the mainstream of national brands. But with the rapid development of digital technology, the security field begins to have a comprehensive digital transformation, ever since the year 2000, the digital security market gets a rapid development in China, and a number of new Digital monitoring products enterprises came into brith, of which the representatives of the dvr manufacturer on behalf of the digital security products rapidly rise, which in just a few years time, digital monitoring technology is applied to all industries, and make a positive contribution to social stability and the stability and unity, but also greatly change the original monitoring market, the analogy monitoring system products gradually withdraw from the market, as a major component of digital security engineering, the DVR recorder has been widely used, and the national brand products gradually occupy a major share of the market.
Statues of Digital Video Recorder
From the industry as a whole, the market demand is the integrated digital multimedia monitoring system, in accordance with the user's security requirements, and combined with self own prevention, and form the security system to meet the actual needs of people, to achiever the video and audio monitoring, control and record storage the information. During the promotion and advertising process, some manufacturers think that DVR products is the universal digital monitoring core. But the core issue of the DVR is only the problem of digitizing video compression and storage, the contents of the "control" is relatively lacking. While in the practical application of the monitoring system, the functions of DVR recorder is more to play replace the traditional analog recorders, and currently, the DVR technology is still in the early stages of digital monitoring systems development.
Various Series of Digital Video Recorders
Till today, the development of DVR technology is relatively mature, and the technology proposed by the manufacturers for the security industry's real needs and different places for special applications improvement and solutions can be described as flourishing, from the M-JPEG, MPEG-2 to the popular MPEG-4, H.264 compression technology, from soft compression to hard-compressed, the increasing video approaches (4,9,16,32, etc.), to the system and network functions, the types is so many and almost make people dazing. With a variety of application environments, DVR products are researched and developed into different series of products. On the market a variety of brands, numerous models, the functional characteristics of different DVR and wholesale GPS Tracker and so on. But in a word, it can be divided into two categories according to the system structure: the PC DVR and embedded DVR based on the PC structure.
