2-megapixel ip camera is the mainstream in surveillance industry

The mainstream IP surveillance camera is 2.0 megapixels,view from the monitor display device,even if a surveillance camera is able to capture higher quality than 2 million pixels, the entire image can not be reflected on the display,200 million pixels is top-level configuration of the monitoring

According to IMS Research forecasts about surveillance market this year, the output value of the global network-based video surveillance market will be more than 2012, accounting for nearly 40% of the entire video surveillance market. With the increasing competition in the surveillance market, video surveillance equipment vendors on the one hand to explore what the mainstream HD ip camera, on the other hand, they also strengthen the functional changes and good after-sales warranty and service projects in accordance with the promotion different. But when pixels of surveillance cameras in increasing these pixels are not used to improve quality, but turned to other functions. The higher the resolution of the image in fact lower the sensitivity in security applications, it is easy to lose sight of this, especially in low-light environments. To obtain higher resolution images, the image data space occupied by the greater, thus creating excessive network bandwidth and storage difficulties, eventually leading integrated construction and implementation of the higher cost. The image sensor determines the quality of megapixel ip camera, the majority of the sensor is an aspect ratio of 4:3, but in order to accommodate more pixels, Sony uses a 16:9 image sensor, the size of each pixel is greater directly improve the image resolution, and sensitivity are increasing. Quality generated by the ip camera, network bandwidth is also very important in addition to relying on sensors. In a monitoring system, how to more effectively control bandwidth allocation can not only save storage space, the image quality will not be affected. In a variety of network monitoring solution, it was suggested to use the SVC video data into different levels of resolution, effectively alleviate the pressure on bandwidth and processor resources, you can adjust the image size and frame rate response to this demand, to meet the affordability of devices of different customers in different network environments.

Multi-stream means that the monitoring system allows different types of video compression formats, such as H.264 and M-JPEG data stream transmitted through the network bandwidth. Stream processor depends on the camera, some manufacturers use the core stream control opened the gap with other enterprises, the codec also may cause the front-end and back-end product is not compatible. Most manufacturers of surveillance cameras to provide at least two stream, the stream is divided into the main stream and the sub-stream, and select the type of the code stream according to the type of monitoring purposes. General computer monitor requires the ip camera main stream, according to the resolution of the display to provide a sufficiently clear video images; mobile phone monitoring select sub-stream, so that can save bandwidth of other mobile remote monitoring do not need to provide too high image clarity . HD stream control and management functions allows users to transfer and storage stage-managed images without losing any signal affecting the image quality. Another big advantage of this function is to control terminal can be an important quality Return to the command center, thus easing the pressure of the bandwidth and greatly reduce the processing load of the remote client.
In order to broaden the field of video surveillance applications, businesses have been offering for the industry's products, such as commercial buildings, education, traffic monitoring, safe city, the airport and the financial HD images require a higher monitoring equipment. For different applications, the ip camera must also designed to meet the stringent conditions. Some surveillance cameras are used for oil and gas, coal mining or pipeline construction, they must be subjected to high temperature and harsh environment test, which requires surveillance cameras have sufficient temperature capability, while ensuring the reliability of the monitoring performance. The normal working hours of surveillance cameras directly exposed to the sun, the temperature increases to 15 ° C, work in normal outdoor temperatures under 45 ° C inside the camera is likely to reach 60 ° C. Surveillance cameras used in desert areas, the interior must be equipped with a temperature condensation system, in order to protect the normal working of the device in the non-high temperatures. With the rapid development of urban transport, domestic security companies vision aimed traffic monitoring, road monitoring offers a variety of identification module and fast image capture technology, in order to monitor the traffic situation and the ease urban congestion pressure.
Megapixel ip camera industry opportunities, or the manufacturer changes of service and solutions, its purpose is to reduce labor costs through the use of a monitoring system to solve the various problems encountered in life. Domestic surveillance market has not yet fully expanded for security companies, there are also a lot of pressure, but now IP-definition monitor market in addition to changing the image quality, network cameras supporting functions also will upgrade, multi-stream control effectively reduce the bandwidth pressure the 16:9 sensor for megapixel ip camera effective pixels exceeded 2 million, in the harsh environment monitoring inside the ip camera can also install air condensing unit ... all this change have proven network monitoring powerful scalability and the pursuit of high-definition images.
