Global IP Camera surveillance market to the development of high-definition
According IMSResearch security monitoring market forecast, this year's global IP Camera video surveillance market value will exceed 2012 $ 5.4 billion, accounting for nearly 40% of the entire video surveillance market. With the increasing competition in the surveillance market, the manufacturers on the one hand to explore what is the mainstream HD IP Camera, on the other hand, in accordance with the difference in the field of promotion, strengthening functional changes, good after-sales and warranty services.
  This year, the the mainstream network control camera 2 million pixels. Judging from the monitor display device, even a surveillance camera is able to capture higher quality than 2 million pixels, the entire image can not be reflected on the display, so 2 million is the top for control and display technology with.
  Network monitoring fully upgraded 2-megapixel camera pursuit
  When high pixel aimless, the manufacturers do not seem as. These pixels are not used to improve the quality, but turned to other functions. In fact, the higher the image resolution is lower sensitivity. Security applications, it is easy to lose sight of this, especially in low-light environments. The same time, in order to obtain higher resolution images, the image data space occupied by the greater, thus creating the problem of network bandwidth and storage, the final integrated construction and implementation of the higher costs.
  Sensitivity and network bandwidth
  The image sensor determines the megapixels quality of the monitoring camera, most sensors an aspect ratio of 4:3, but in order to accommodate more pixels, Sony uses a 16:9 image sensor, each pixel is larger, directly improve the image resolution, and sensitivity are increasing.
  Surveillance cameras internal structure
  Quality generated for the front of the Network Camera addition to rely sensor, the network bandwidth is also very important. In a monitoring system, how to more effectively control the 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, which effectively alleviate the pressure on bandwidth and processor resources; In response to this demand, you can adjust the image size and frame rate, to meet the affordability of the equipment of different customers under different network environments.
  Multi-stream video compression
  Multi-stream means that the monitoring system to allow the different types of video compression formats, such as H.264 or M-JPEG data stream transmitted through the network bandwidth. Stream depends on the infrared IP Camera processor, some manufacturers use the core stream to control the gap between La and 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. Under normal circumstances, the computer monitor needs camera main stream, according to the resolution of the display to provide a sufficiently clear video images; mobile phone monitoring select sub-stream, one save bandwidth is mobile remote monitoring does not require too high a clear image degrees.
  The Network Camera stream size of the impact on the quality
  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.
  Surveillance cameras in special circumstances
  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 camera must also designed to meet the stringent conditions.
  Some surveillance cameras used for oil and gas, coal mining or pipeline construction, can withstand high temperatures and harsh environmental challenges. This requires that surveillance cameras have sufficient temperature capability, while ensuring reliable monitoring performance. Surveillance cameras directly exposed to sunlight, the temperature in the normal working hours to improve 15 ° C, so when working at normal outdoor temperature 45 ° C, inside the Network 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. Identity Module offers a variety of road monitoring and fast image capture technology, in order to monitor the traffic situation to ease urban congestion pressure.
  Monitoring applications in extreme environments
  Megapixels surveillance cameras industry opportunities, or the manufacturer changes of service and solutions, its purpose is to reduce labor costs, monitoring solve the various problems encountered in life. Domestic surveillance market has not yet fully expanded, there are also a lot of pressure for security companies. -Definition IP Camera surveillance market in addition to changing the image quality, supporting the function of the camera also will be upgraded. Multi-stream control effectively reduce the bandwidth pressure; 16:9 sensors for megapixel cameras exceeded 2 million effective pixels; monitoring inside the Network Camera can also install air condensing unit in harsh environments, ... all this change that this network monitoring powerful expansion and the pursuit of high-definition images
