Still my question unanswered. Will F1.0 make the image quality clearer & better in IR mode because I will force it to be in IR mode all the time (reason I'm considering this model because I assume F1.0 will give better image quality compare to normal IR cam)I'm sure having IR and white LED will cover a lot of conditions; but it likely will stay in color under darker conditions with neither IR or white LED if the sensor were larger; its 1/1/8" sensor is optimum for a 4MP cam, an 8MP cam would allow color with NO supplementary lighting under darker conditions with the larger 1/1.2" sensor (as compared to 8MP with a 1/1.8").

I confess, IGreat chart!
Some cameras can do that.I heard that white led will only come on when there is smart event triggered. I havent tested yet, just rumors
It has three modes:I heard that white led will only come on when there is smart event triggered. I havent tested yet, just rumors
For the 4MP Hybrid light vs 4MP Colorvu, I'd choose the Hybrid light version as both 4MP versions share the 1/1.8" sensor (except if strobe light/speaker were needed as the Hybrid light model doesn't have a Live Guard variant (at least not yet in the UK)So you would choose this over the regular 8mp colobus cameras with the 1.2 sensors?
I’d be curious why they didn’t use the 1/1.2 sensor. Maybe to save money or a technical reason behind the choice and the switch to IR.For the 4MP Hybrid light vs 4MP Colorvu, I'd choose the Hybrid light version as both 4MP versions share the 1/1.8" sensor (except if strobe light/speaker were needed as the Hybrid light model doesn't have a Live Guard variant (at least not yet in the UK)
A more difficult choice for the 8MP models though. The one I've installed is in the back garden and has zero supplemental light/street lighting visible on a night, totally pitch black, so the Hybrid is preferred as I don't want to see the white LED. However where there's enough supplemental light around the camera that a reasonable exposure time can be set without needing the integral LED, the ColorVu with larger sensor might be preferred. I'd have to do a side by side comparison in the same location to decide which is preferred.
My guess is that it's a current technical limitation. The Hybrid light models use a new lens design with 'super confocal' technology. The focus point for visible light and infra red light are different and the lens has been designed to counter this focus shift by reducing optical light dispersion, so that the point of focus for both visible and white light are the same. The large f1.0 aperture makes the depth of field small and perhaps combined with the larger 1/1.2" sensor, that focus shift (variation in the point of focus between white light and IR) would be too great to be dealt with using super confocal.I’d be curious why they didn’t use the 1/1.2 sensor. Maybe to save money or a technical reason behind the choice and the switch to IR.
The larger the F Stop (ie the smaller the number) the less depth of field will be in focus. Moving to a F1.0 will result in a very narrow depth of field being in focus. Also, while the F stop shouldn't theoretically change the image quality, many lenses do have image problems at the extreme ends of their aperture's range due to the quality of the actual lenses (I'd say glass, but I don't want to suggest that all lenses are made of glass) used and the lens design itself.Still my question unanswered.
