IP camera or web camera, network video camera from
concept to video network, network, server + camera now mainly divided into civil
and industrial use (used) monitoring project of two main is adopted, civil and
industrial cmos sensor with the main using CCD camera. We mainly discussed here
at the camera, network popularity than network video server, the main reason is
that it is no single camera, video server as wide + all kinds of common video
camera, and far more network from the perspective of the maintenance and
stability than video camera + server, and its share price is one of important
factors, of course, network integration camera, simple interface, easy
installation and construction of network video camera is unique advantage.
A network video camera and can be regarded as a combination of a
computer. It can capture video and directly through the IP network for
transmission, thereby authorized users can through standard based on IP network
infrastructures in local or remote sites achieve, video data storage and
management.
Network cameras have their own independent IP address can be
connected directly to the network and built-in Web server, email client, alarm
management and programmable ability and other many intelligent function. Network
cameras with PC connection without, it can operate independently, and can be
placed in any one place with IP network interface. Video camera with the
simulation, the network server + compared with higher integration camera,
installation is more flexible, and some even need only a piece of string can
use, and video server or analog camera + need a certain distance from the video
transmission, simulation environment influence more than the network video
camera.
Besides video information, network cameras can achieve the same
network connection through other functions, and some other useful information
transmission, such as video, audio, digital mobile detection, input and output
(can be used to achieve alarm linkage, such as trigger alarm or activate spot
lighting, etc.), for PTZ or serial data transmission device driver serial port,
etc. The image cache network camera can save and sent alarming and video images.
In recent years, the network technology has caught the analog video camera, and
can also satisfy the video monitoring the actual requirements and
specifications. In addition, still can offer a series of network video features,
so high in some respects, even more than analog camera.
In short, the
camera can only transmit analog video signal, the one by the operator and
performance level, DVR network video transmission, however, can be a full-duplex
digital information, and with other systems can be effectively integrated
equipments, so that they can be in a scalable distributed, the environment to
achieve higher performance level. Network cameras can with multiple applications
system parallel communication, so as to realize the various functions, such as
the motion picture detection, or send different format video etc. But we should
notice a problem, at present the development of simulation camera relatively
mature, a variety of types, network video camera is seldom, it also limit its
application, and video camera + simulate the network video monitoring of the
server will be more easily combination of traditional analog video camera for
network upgrades the function, and can be easily combination of network,
network, and network QiangJi hemisphere seek, network, and network infrared
waterproof high-speed ball of network monitoring equipment, and will make one of
these devices are directly to the network, the high cost of camera traditional
camera manufacturer in the aspects of so much, but we believe that once the
market mature, these products will be in a very short period of time.
Network camera prices and offer the same video quality than current
simulation is much higher, video camera than video server + simulate the price,
but also because of its high integration and flexibility, the higher the
convenience, the installation of future will be a bigger share of the market.
Of course, from the current situation of the application of the market,
because its price factor network video network infrastructure and the number of
issues, not much, but we believe that with the popularity of Internet technology
hardware, network bandwidth, improve the service quality of the camera, network
application prospect in the market is very wide.
