I think there is a problem in this test, the TVT model is 2mp IPC and Hikvision is 4mp IPC, comparing images doesn't make sense I would advice comparing the same image sensor to make the comparison fair.
I understand where you are coming from with regards to a 1:1 comparison with resolution. However, do take in to account the fact that the Hikvision ColorVu tested stronger than the InVid here in multiple facets, namely:
Low light, where the Hikvision ColorVu is overall brighter than the InVid, producing clearer details.
Dark, with less gain/noise than the InVid, producing clearer details.
White Light Illumination evenness.
WDR, as the Hik. ColorVu is true WDR vs. InVid's digital WDR.
Price, as the Hikvision ColorVu is cheaper than the InVid camera tested here.
Have you read our other bigger shootouts, such as the Color Low Light, WDR, and IR Shootouts? We make a variety of comparisons between resolutions, with higher megapixel cameras falling below low megapixel cameras routinely. The ColorVu has (so far) been the strongest white-light LED performer we have tested, so wouldn't you prefer seeing how a newly tested white-light entrant compares? Please comment with any additional questions you may have, and I'd be happy to assist.
I would love for you guys to test the Bolide BN8035F (Raysharp OEM). That camera is one of my favorites...it has white LEDs, IR LEDs, a mic, speaker, siren, and a PIR all built in...it is truly a great "bang for the buck"!
I would agree with UD#2 that this report is slightly unfair to the Invid based on resolution. Since there is a 2MP ColorVu available it would be nice if the test were re-run with it to see if the Hikvision unit is as capable at half the pixel count (I suspect it is) and provide a bit more accurate comparison to the Invid.
Thank you for the feedback. For cameras with white light illumination, we usually will let the camera to do all the lightning in the room, and there we can test strength, coverage, color fidelity and relative noise.
Depending on what we test next, we can certainly try testing with a subject shining a light back at the cameras to see how cameras react / how well HLC performs. However, we have not done so for this test. Perhaps we can look at Invid again once the thermal fever camera/device rush is behind us.
