China is currently in the development of security products continue to progress, but there is a problem is still not universal network camera , which is also the case with our country has a relationship so specifically what causes this problem arises it Here we give detailed introduction:
First, the technology is very mature with respect to traditional analog surveillance system already familiar with networking and commissioning for analog systems engineering personnel, it is relatively unfamiliar , or a little more difficult . As we all know , the network camera is relying on the existence of the network , the network itself and the status of the application effect is closely related to network cameras .
Throughout the network environment based on the application of effects, such as network monitoring system is based on a network has been built , the original network infrastructure can meet monitoring requirements , needs to be considered ; while the new network -based network monitoring system, Construction of the new network will be faced with greater investment environment , users may make large investments unbearable .
In addition, access to the IP camera will be domain names, IP addresses and other problems , and network security issues are also the focus of the user , so that the joint effect of many problems have hampered the widespread application of network cameras . But in network security , now Megapixel IP camera have built-in VPN protocols of international norms , enabling seamless connectivity and network security devices can be safely connected to the internal LAN from the Internet , which greatly improves the audio and video security , to prevent the camera through the network cable intrusion internal network. In addition, the generally high-definition network camera also has a built-in UPNP protocol , plug and play , no need to change the firewall settings and other network security devices , but also reduces debugging difficult.
Second, some standard definition network camera image effects might as analog surveillance cameras and IP Cameraalso vexing non- real-time , are also boosting the still massive selection of analog surveillance cameras and firmly occupy the mainstream market surveillance position. However, with improvements in technology and user needs improvement, high definition has become security vendors continue to pursue the goal , 720P/1080P HD surveillance cameras more and more favored by the users .
In some mainstream manufacturers , for example, last year the grand launch of a full range of one million high-definition surveillance cameras are to follow the standard H.264 algorithm , can achieve 1920 × 1080,1600 × 1200,1280 × 720 full real- million HD, 1600 × 1200 video multi-stream video output, can easily achieve high-definition monitor , can truly capture clear image detail , the picture quality than conventional D1 promoted four times , so that the high-definition surveillance cameras has become more widespread application areas can be optimistic forecast , the HD , network video surveillance trend, high-definition network surveillance cameras will be showing a rapid development trend.
Finally, the network camera costs are still high. Compared with analog surveillance cameras , because the network camera market is not mature, their prices are high , so many industry users prohibitive. With China's domestic enterprises bigger security surveillance cameras gradually mastered the core technology , domestic compression chip large-scale application , many domestic security companies introduced a wide variety of IP Camera. Some manufacturers even have a full line of high-definition network cameras, to provide users with more choice . This means that prices will inevitably have a more substantial downward adjustment , the current price of high-definition network surveillance cameras has become increasingly close to traditional analog surveillance cameras, so that more users can afford network cameras.
