Development Treads of Video Recorder

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.
