20MP Indigovision 5K Has Same Specifications As Ampleye Nox-20

Well then, it's obvious that they are not one and the same. I talked to the IV rep yesterday and he told me that Ampleye is not the manufacturer of their Ultra 5K camera. Since you yourself claim that their specs are the same, how would you jibe the differences you just pointed out?

As far as my 30fps comment, I didn't mean to say that would apply to all cameras, just <= 1080p that we require. I understand 30fps x 2 would be difficult to achieve at 20MP. That begs the question: Ampleye claims their camera can deliver 30fps @ 20MP. I'm skeptical about that claim since many manufacturers have trouble delivering 30fps at 1080p. In one area of their data sheet, they claim "20 MP at 30 fps" while in another area, they claim "up to 30 fps". I've seen many manufacturers fudge their camera specs with that "up to" phrase without providing a frame rate vs. resolution chart, which typically reveals that 30fps is only acheivable at lower than maximum resolutions.

Where did you find full specs on the IV camera? I've tried clicking on the link to its data sheet and wound up back on their products home page. I've brought that to their attention but I can't discuss this in depth without having both spec sheets side-by-side.

All I can say is that your argument that they are one-and-the same flies in the face of at least the one spec you admit is different.

One more comment and I think I will have filled my quota for the day in this discussion ;-) :

I believe that you and I agree manufacturer spec sheets often, shall we say, stretch the truth. This could very well be another case of that.

The only way to tell for sure is to test them side-by-side. Perhaps IPVM could accept that task since I will not likely do so - that high a resolution is not in our wish list plus IV's apparent requirement to use a VSM-4000 Video Stream Manager (which I take is their proxy server or camera gateway that I've discussed before) makes it that much more difficult to justify. Not to mention our regs call for 30fps on all cameras.

Carl, most importantly, they are both 5120 x 3840 20MP, 35mm sensor CMOS, global shutter cameras with the same hybrid JPEG2000 high res / H.264 low res stream combo with the same 105 / 117 / 96 dimensions. If that's a coincidence, it's a pretty amazing one.

I don't think anyone is 'stretching the truth', well, except for your rep.... IV is simply doing its best to downplay the source of this technology.

Again, I don't understand why that is such an issue. I would bet that many manufacturers don't or won't release OEM info. How does that make IndigoVision unique?

I also find the JPEG2000 spec interesting. IV has supposedly sworn off all compression types other than their version of h.264. In fact, darned near every manufacturer abandoned JPEG2000 with the sole primary holdeout being Avigilon, and even they have been downplaying it of late.

A related source of puzzlement is that Avigilon is "stepping" on many VMS manufacturers' sales due to their lower cost per channel. Since Avigilon is one of the few companies that support JPEG2000, you would think a competitor would avoid any perception of adopting their near-proprietary technology at all costs. IV requires what appears to be a form of codec convertor / stream redistributor in the VSM-4000. Why bother?

You have mentioned numerous times that JPEG2000 is a dying codec. What brings this dinosaur back out of hibernation?
