I'm sure we are all familiar with camera phones. They started with VGA (640x480 pixels), XGA, SXGA and UXGA and so on. These are names for the difference in resolutions which is measured by pixels. Hence the names, 1.3 mega pixels(MP), 3 MP, 5 MP and so on.
So, what does this mean?
With more pixels of capture, do we get much better picture? Yes of course. With the more pixels in capture means the more we can digitally enlarge the picture on our computer screen. Gone are the days of analogue cameras and video monitors. In this day and age, we look to the computer screen to display out favourite photos. Gone are the days of analogue CCTV also.
Stardot is one of the pioneers of manufacturing high definition CCTV and video servers. The stardard digital video recorder (DVR) that we buy for our digital surveillance captures at D1 resolution, which is basically 0.6MP. With Stardot high definition CCTV cameras, we start our image capture at 1.3MP up to 5MP. To date they are the more competitive in pricing, flooding our global market with high definition CCTV in a hope to improve digital surveillance solutions today.
A major concern with the current digital surveillance market is that people think that high definition CCTV will replace existing digital surveillance solutions like PC based DVR and standalone/embedded DVR in the market. This is far from true. As a matter effect, high definition CCTV merely fills in gap which was previously no achievable with standard digital surveillance solutions.
The high resolution of captures means more pixels of capture and also means bigger file of capture. This will lower the frame per second (fps) of capture. Therefore we still require D1 resolution if we want a catch a snatch thief on the run.
