Just received IPC_5449T1P-ASE-D-3.2mm dual lens from Andy Most Impressed with the prompt service and the camera

I only turned down the IR on T5442T as the picture was noisy after I set up the B5449T under the T5442T .
Question If two cameras are setup close do you get double the IR, as in attachment on post #16

Yes you will

Can you share a picture of the Night street from T5442T , while forcing it to be in color? Is your D2 with matching sensor sizes (older model had 1/1.8" + 1/2 " sensors ) ?

The D2 is the new model two equal sensors.
I will try the T5442T in colour tonight.

Here is a comparison of the two cameras on colour setting.

The D2 is clearly better at the below settings

WOW pretty big difference. I have a few T5442T running in color at night (they are LED version but i think sensor is the same), and thought they were pretty good. But D2 is just so much brighter.

The normal 5442-LED-S2 compares similarly to the 5442-ZE, while being cheaper. I dare say that 3x the light is what makes the difference here.

Hi Perimeter,
Could you please explain what you mean by 3X the light.

 

[Perimeter]

The 1/f=1.0 lens gathers about 3 times as much light as that 1/f=1.8 lens. (1.8² is 3.24)
That is because the lens area is ~3 times bigger but focuses the light on the same sensor size.

Thanks for that explanation, looks like the D2 is the way to go for any lit areas. As long as the extra tech in this camera is reliable.

 

[Perimeter]

If the area is reliably lit, I would probably settle for the 5442-LED-S2, as it seems to be the above camera without IR support. I would only consider the D2 if the light isn't reliable or if there are unlit regions within IR range too. (or if I had emergency power in case of blackout).

@Cooltiger which firmware is running, on your camera ?
