Difference between CNB BBM-20 & CNB BBM-24F???

[Bmonaweck02 0]

I am looking at getting CNB BBM-20 Cameras. But I see the CNB BBM-24F and the only difference I see is that is had 2 ICR(which IDK what it is, I assume it is 2 IRs) and that it has a min lux of .005 not .05.

 

I would like to get the CNB BBM-20 because it is cheaper, but would also like to know the difference.

BBM-24F is True Day Night (Mechanical IR Cut Filter AKA ICR).

Neither have IR, they are just Day Night box cameras.

Add your infrared separately.

So basically they are the same camera?

 

They are both "True Day Night" Cameras correct?

Yes he is correct, spec sheets shows it as TDN

Seems it is just not as sensitive in low light as the 24F, an its only 12VDC where the 24F is dual voltage.
