CCD vs. CMOS

The Dallmeier video clip demonstrates the two techniques using diagrams.CCD sensors capture the charges produced by light, and are converted to an analogue signal. With CMOS sensors however, each pixel is assigned a digital value. Learn more about Dallmeier IP network cameras at: www.dallmeier.com/products/si...

Thanks for this great video ... this is make it easier to understand how the CCD have only unique electrical node that convert each pixel photons into electrical analouge signal .. and why the CMOS ( Complimentary Metal Oxide Semi Conductor) is more speedy. Thanks again and am wondering how people comment without having the right background ... :)

Generally speaking, CCD sensors were seen to be better, unless their use in expensive, high end cameras by premier companies was just belligerence. CMOS sensors were cheaper, and that's where the issue lays. The difference in speed is academic with contemporary technology being so fast. Cost is paramount. CMOS sensors are cheap and require less processing capacity, and that is where their popularity, preference and future development is determined.

Power consumption is an issue too, apparently - CMOS requires far less power than CCD. (or has that situation also changed?)

WHICH IS GOOD CCD OR CMOS??

[@Dallmeier-video-security]

+jeanie Dear Jeanie, thank you for your comment. The comparison is a very comprehensive topic. In our video “What is the Blooming effect in CCD chips?” we describe one significant disadvantage of CCD sensors, the so-called blooming effect: kzbin.info/www/bejne/Y3XShZqHl6Z_i5KIhis is where, in strong light exposure, the excess charge is emitted from a pixel to those surrounding it, creating overexposed picture areas. This is one reason why we use CMOS sensors in our cameras.

CMOS has its own problems as well, namely that of the rolling shutter. One gives you spatial distortion, and another gives you temporal distortion. You have to decide for yourself which you'd rather not have.

CCD has a big sensitive to a high temperature,so due to the fact of that, you need to take care to expose the camera to the sun, so It´s used as cameras in telescopes,more quality although more slow. And CMOS,faster, can expose to the sun and high temperatures but have less quality,cheaper and very easy to implement

You have the wrong labels on them. They should be the other way around (CCD on the right and vise versa). Good video otherwise ;)

[@gregsullivan7408]

Nonsense - the labelling is correct.
