Megapixels purchase points
Megapixels current market point of view, the compression is still RWR/MJPEG/MPEG4 quantitative data in terms of bandwidth, the transmission rate is not more explicit, so that users understand its ultra-high the image quality, but is still under such a high image quality image continuity and transmission bandwidth required to be puzzled. So these products in the choice need to pay attention to the following points:
1, the exact understanding of high-quality images of the actual bandwidth, the transmission rate and quantitative indicators, and scientific assessment of network resources for project construction;
2, using the CCD or COMS photosensitive chip? CCD chip solution, which (single / multi-channel) output balance "technology, the frame rate to meet the actual demand;
3, with the problem of the optical lens, must be supporting the use of millions of industrial-grade lens or can not reflect the high quality of the camera advantages;
Fully examine the actual performance of such products in low-light environments, especially manufacturers what technology is used to compensate for low-light imaging;
Inspection of such products software features and SDK technical support in order to be compatible with other systems or other devices.
With the international market and domestic market for popularity and extensive use of the monitoring system, people have become increasingly demanding image: from the beginning to see the image to clear image processing and analysis to future energy the high definition image. The entire market high-definition, network-based, intelligent atmosphere, consumer demand is undoubtedly stimulate the rapid spread of the megapixels technology and products.
