dofanoe7 0 Posted July 1, 2010 is it true that only Zoom camera using 1/4" CCD sensor?. Most of the datasheet that i've read from various vendor/producer of CCTV camera is mentioned that their Zoom camera is using 1/4" CCD sensor. why not 1/3"?, the bigger the better right?. thanks!

Soundy 1 Posted July 1, 2010 Size concerns mainly, I suspect, needing to keep things compact to fit everything within a tight form factor, and light to allow fast reaction. Cost issues, too - since PTZs inherently cost more, using the 1/4" sensor helps keep the overall cost down. A smaller sensor allows a smaller lens to provide the same zoom factor, as well. There are 1/3" PTZs out there, but they tend to be a lot more expensive (check out the Pelco Esprit line). Share this post Link to post Share on other sites
Baylab 0 Posted July 3, 2010 some cheap single board(most of the the are China made) also use 1/4 inch CCD. and some miniature camera also use 1/4"CCD. however, such kind of miniature models are quite expensive. (some of them with a diameter around 17mm, 13mm or even 7mm). Share this post Link to post Share on other sites
