If I were to guess, I'd say that Avigilon is just getting out in front of all terms that can be used for comparison because that's how executives and other non-technical people usually determine value.
I'm seeing it as a smart blanket strategy. Whatever unit you are using, whether it be megapixels, HD-style (720p / 1080i / 1080p), or "K", Avigilon always has a higher level of capability.
So an executive talks to two potential providers. One goes in and says "and we can even give you 4K quality just like you're seeing in home theater", and the next says "we can give you 7K, which you've probably never even seen before".
You're not wrong that it's a more impressive comparison - since reducing it to MP gives you the chance to say "nearly 4 times the competition".
I think they just want to know that even an unattended prospect can read the specs and know that their product will win the contest, and to do that, you have to define your product in the terms that the competitor uses.
I agree. They may be thinking everyone will release or announce forthcoming 4K cameras at ISC and this slight change in nomenclature will help them one-up everyone. There will undoubtedly be quite a few people at the show who do not realize 4K=8MP and 7K=30MP... they're just hearing buzzwords. For those people this may be effective if "3K" in additional resolution is worth an extra 7K in dollars.
the reason 4k is not flying of the shelves is becouse their performance is rubbish, the Sensor and Lens are not keeping up with the clarity they SHOULD be capable of.
the reason the Avigilon is SO good is they go with a decent sensor and decent lens, the reason they are NOT selling is they are asking your left kidney for them, which is 1, a bad sales move and 2, why Hikvision need to duplicate it for 1/10th the cost.
I agree that it's not going to be 10x better, but it's the price point that folks are going to be looking at, and at this point it makes no sense, the Axis has a nice lens, the Dahua your stuck with 70 degrees unless you buy another lens (there goes the $$$)
when Hik makes one with a 90 degree lens (in THEORY you have the additional detail, why not make use of it for a wider area) still, the low light is so bad on anything recent... would love to see a comparison of whatever top of the line Avigilon with a Large sensor + great Lens to see how it stacks up.
Love that the Dahua is actually a 12mp native, gimmie 12mp@15fps over 4k anyday
One thing that comes to mind with these _K cameras: are they going to be 16:9, like 4K or 8K (actual standard resolutions), or will they still be 4:3? Might not matter to many, but especially in very wide areas, it would seem that taller fields of view are more useful.
I don't see any implicit or explicit reference to increased frame rates anywhere in the literature. As I mentioned earlier h.264 is limited to a max bit rate, so I am not sure how much faster it can really get...
Most manufacturers in 2015 are high profile, even on low cost gear, and I see Level 4, at least, usually 4.1 or 4.2. I'm not sure I've seen anyone at Level 5. So a theoretical max limit of 62.5 Mb/s. Honestly, anything much more than that and you should probably be on a GbE link, anyway.
The 16MP H.264 has a max bitrate of 36000kbs
the 30mp will probably be a reduced framerate and a similar max bitrate of 36000kbs
HDSM2.0 is novel and proprietary and will not work with ONVIF as it splits the image out into mulitple images/sections with various quality for transmission depending on what portion of the image the client is viewing
Thanks for sharing! We had not seen Spark before. For those interested, here is Spark's website / camera page. Ethan is going to reach out to them to learn more. One confusing thing with their website is that says up to 36MP but then under highlights it says 12MP CMOS.
a higher amount of Megapixels only matters if the Imager/Lens allows you to see benefit of it...
there are 10mp cam's out there that don't look as good as 3mp, the 30mp Avigilon looks amazing becouse it's a full frame sensor and full size Lens, simple as that.
I'd love to see a 4k cam (real 4k, 4000/2160res) built by Hik with a 1 or 2 inch sensor, nice lens (make it compatible with some widely available DSLR Lens) and actually enjoy the quality without the off the planet price tag (so something like $3-600)
