Anyone use this q-see camera....

Yeah some of the ones without IR filters still look pretty good. Some of the processors today can process the colors really good even without a IR filter, The Effio for example is one of them. But whenever you compare the Effio with no TDN, to an Effio with TDN, the difference is noticeable (the one with IR cut is a TDN:

The thing for me is though, true TDN compared to a digital menu item for day/night settings. In auto, where I suppose the camera goes from color to BW at night, is there is huge difference between TDN or digital auto day/night setting. And where would the biggest difference be- at night in BW or during the day in color, where the absence of TDN could distort good accuracy. I guess there's no way to tell except to see for myself with the cameras in question. But I'm not looking for beautiful still images. I'm looking for accurate color and BW at night so as to deliver really good ID shots. If digital day/night isn't as good as TDN but not by an appreciable difference, it would mean the difference of a better chip and larger varifocal selection in cameras. Long and short, if it's not a huge diff, I'd go for the better camera overall. Right thinking?

I think you misunderstand.

 

Color IR or Digital Day Night = NO IR CUT FILTER is ever placed over the chip, therefore colors are washed out when exposed to Infrared, eg outdoors under sunlight, some also look terrible under indoor lighting. These are the cheaper of the day night cameras, and hence are not considered a True Day Night camera.

 

TDN = Mechanical IR Cut filter, removable during the night, it goes back over the chip in the day. Therefor you get rich colors as the infrared is blocked from entering the chip, and in most cases TDN cameras are generally a much better camera with a more expensive chip and also more sensitive under low light.

 

TDN is normally always a better camera overall, than a comparible model that is only digital day night.

 

BTW both switch over automatically.

Guys- thanks a ton for the pics and clarification. Even though I'm considering an effio chip, I don't wish to run without TDN. So I'll go for a super HAD2 with TDN with an acceptable varifocal offering as opposed to an effio without TDN. I currently have one TDN camera and I really like it a ton, so all cameras going forward will have it. I knew this, but there were some features that side tracked me from remembering how important it is, bottom line. Thanks again.

cheap cheap color IR > cheap color IR > TDN IR > No IR

Great posts guys

I see cameras now that offer WDR,3DNR and Sense-up but don't mention ICR.Are these three features a spin off of the original IR Cut filter feature?

No, IR cut is a filter that physically goes over the chip.

So what is the true purpose of these extra features? How much do they really help? Or are they just to artificially improve the budget cams to make them more marketable?

WDR in these cases are typically digital WDR so its not to compare with TRUE WDR such as Double Scan cameras which can cost ALOT more.

 

Sense up is just slow shutter in most cases AFAIK - AKA DSS.

 

3DNR works to a degree but if you adjust it too high the video can look worse.
