subject: Monitoring Display Selling Well?? Video Hd Technology Becoming Mature - Video Surveillance, [print this page] All network monitoring systems are good, focus on customers in the eyes of the images turn out good, HD is always in pursuit of the user. At present, many users do not know what the network is like high-definition in the end and effect, so they have no real definition of the concept. Once the effect of high-definition system was user perception and recognition, the user Policy City, under the influence of application will rapidly expand, security monitoring devices may be formed in a large replacement market opportunity.
Based HD monitor High definition Network Camera Video surveillance source, it has high-definition video encoding and IP encapsulation, through the IP network to carry high-definition images, enabling high-definition Monitoring , Video and other monitoring functions.
In the transmitter, network camera with integrated image capture, video compression encoding, Communicate Control and transmission interfaces, video data through the IP network output.
Part of the image acquisition, CCD and CMOS sensors are two types designed for different needs, CMOS high pixel has a certain advantage, while the CCD better adaptability of the control scene. In the video coding part, different compression algorithms and algorithm program determines the quality and high-definition image coding efficiency. In the communication control section, network adaptability, Security Nature of the package stream format and transfer functions, depending on the monitoring system of planning and design. In the transmission interface section, different network access methods, such as wireless, cable, etc., can be well supported; In addition, some network cameras also integrate the necessary monitoring of other interfaces, such as Alarm , Control, intercom and other interfaces.
At the receiving end, by decoding the output to high definition display devices, such as LCD, through the Recording equipment For high-definition video images.
High-definition image streams as large, generally more than 3Mbps, so the image of the record is an important part of achieving high-definition video. To record high-definition network camera images, we can use the following ways:
PC-NVR Embedded NVR Hybrid DVR Either way, should meet the following requirements, such as:
Ensure that video stored cycle, need enough storage space;
To ensure the effectiveness of multiple concurrent record, that record should not be a bottleneck in the process;
Convenient, fast retrieval and playback efficiency;
Covered with loop mode, multiple coverage should be guaranteed after the recording and retrieval efficiency;
Reliability, cost-effective monitoring should be consistent with operational requirements.
PC-NVR developed using PC-DVR technology, high-definition network camera through the SDK can be provided by the secondary development of storage technology can be used DAS, NAS, IPSAN so.
HD technology maturing
As the end user, be sure, which trades on the urgent demand for high-definition video, which the industry could become the market leader in high-definition monitor, users in these industries will be the first to experience high-definition network monitoring object. Now there are banks, transportation, hospitals and other users in the construction industry or have completed various sizes of high-definition network monitoring system. These applications, indicating high-definition network monitoring has been launched in the market.
