ini 0 Posted April 13, 2009 hello to all. I'm a complete nube so please forgive me for posting this question. I've rummaged through the threads here regarding similar questions but haven't been able to find what I'm looking for. Does anyone have, or know where one might find a demo, screenshot, etc of a 480TVL vs a 550/560TVL color camera? Is there any noticeable difference at all? Many thanks in advance for your reply!

ini 0 Posted April 16, 2009 [vietsymbian ]-- as stated before, I'm a complete nube. I'm speaking of advertised camera specs..you know as in 480TVL, a 550TVL, etc. And I also undertand the variables in the orig. question..so let me re-phrase....all else being equal (DVR's, cable, lenses, and anything else... are there human-recognizeable differences between 480TVL (advertised camera specs) vs 550TVL? Just curious as to if I should invest the extra money (I'll refrain from mentioning model numbers as it's irrelivant to the question). Share this post Link to post Share on other sites
vin2install 0 Posted April 16, 2009 It's not the TVL where you can tell the difference by eye, its the effective pixels. Share this post Link to post Share on other sites

While the top 6 resolutions in your chart are horizontal TVL resolutions (Umatic... (250 lines) to Widescreen DVD (400 lines)), the figures for 720 and 1080 are not the horizontal resolution, they are the vertical pixel count. Share this post Link to post Share on other sites

ini 0 Posted May 3, 2009 Thanks Dopal...I guess I did learn something from it. Since few mfg's seem to list effective pixels, is there a formula for calculating effective pixels or does it depend on the lens type, quality, etc that the mfg uses? In other words is there a way to know what you're getting? Thanks, Share this post Link to post Share on other sites
