A new generation of cost-competitive HD webcam H.265+, which is low in price (not because of poor workmanship, but because of low cost of hardware solutions) and supports intelligent video analysis.This series of products mainly adopts the HD camera chip produced by MStar company, which is the spoiler of HD camera chip. Everyone is not familiar with this company, because THE MStar program was launched this year, which is another step to expand the application of chip products after MStar launched the dashcam program.By the way, it's worth noting that MSTAR chips, or processors, are widely used in cheap, internet-enabled HIGH-DEFINITION televisions, and are the industry's leading provider of TV chip solutions.

 

At present, in the field of security video surveillance, MStar has launched a total of two chips, namely MC313E and MC316DM.It is very surprising that both chips use TSOP packaging technology instead of the current standard BGA packaging technology, which is why the MStar solution costs less than the Hayes solution.Unfortunately, we cannot find any information about these two chips on the official website of MSTAR.However, according to the data of the camera module manufacturer, we can find some basic information of the chip. For example, MSC313E supports a maximum resolution of 1920x1080p, that is, a resolution of 2 megapixels, and a maximum video frame number of 25Fps. MSC316DM supports a maximum resolution of 1944x1520, that is, a maximum resolution of 5 megapixels CMOS source data input, and a maximum encoding frame number of 18fps.

 

Both MSC313E and MSC316DM support the latest H.265+ video encoding technology and downward support h. 264/AVI video compression.Compared with the common H.264 video compression technology, H.265+ video coding technology can theoretically reduce the file size by 70%, thus saving network bandwidth and reducing the video storage capacity requirements.Of course, the smaller video file is conducive to the smooth transmission of HD video by the camera under the condition of low network speed, so as to solve the problem of video lag and serious delay.The H.265 technology is great, but because it's a new generation standard, H.265 video is not widely supported.For example, most multimedia players do not support playing H.265 videos, and most video websites such as YouTube, Tencent video and Youku do not support uploading H.265 format files. Currently, h. 265 to H.264 video converter is very rare.Therefore, the h. 265 video return visit/playback needs to be coordinated with the H.265 network video recorder.

 

As for image processing, it is mainly decided by the CMOS image sensor.Through comparison experiments, under the condition of using the same CMOS image sensor, the video resolution and image quality output by the CAMERA products of MStar scheme and Haisi scheme are not significantly different.MStar camera also supports 2D+3D noise reduction and digital wide dynamic.However, the new MStar H.265+ solution of Linnet has built-in intelligent video analysis algorithm, which can support cross-line detection, item retention/loss detection, area detection, explosion-proof detection, and flow count.In addition, we provide H.265 NVR products that can be seamlessly connected with the new IPC to avoid the need for users to purchase third-party NVR products and worry about compatibility issues.
