Is CMOS cam better or CCD cam better?

depends on your application.
CCD's are widely used and are available in different flavours and prices on the market. Still CCD is the best choice for low light environments.
What they mostly lack is Wide dynamic range possibilities.

Therefore CMOS chips are being used to have pixel per pixel analysis, and able to cope with WDR situtations.

For analogue cctv, the bottom end of the market tends to be CMOS with almost everything else above being CCD.
This has led to the mistaken belief that cmos is an inferior technology.

The two technologies are just different and there are advantages and
disadvantages in both.
Some of the highest quality imagers in the world are cmos.

Cmos is widely used now for IP cameras - the highly respected Arecont
megapixel cameras, for example, are cmos.

If you want to see something interesting, compare the design of the Arecont cameras to the Ganz IP cameras from cbcamerica.

is it interesting to look at the same camera ?
survtech - 26 Mar 2007, 12:32 pm
That's my point. Read the post above mine.

Thanks, that is interesting. So who is the manu?

CBC I assume

guess it ain't CBC, as the also OEM their other cameras.
They just seem to manufactur only the lenses, not cameras.

That is the question of the day. Does anyone know? The reason I ask is that we are supposed to get a demo of an Arecont in June and I'd like to see what compatible competing cameras are out there.

We can't use just any IP camera because our DVR system only has "transcoders" for certain ones (Axis and Arecont are the only ones as far as I know).

It is getting much harder to define what 'Manufactured By ' means these days.


Would be interested to know if the Ganz is identical.
