Bold maybe but poor track record of delivering on such claims, e.g. Testing Lowest Bandwidth Camera? (DVTel Quasar)
And with so many 4K cameras being announced by so many open manufacurers who are not oeming dynacolor, what's interesting?
I think dvtel's analytic cameras are interesting becuase there are few options and ioimage has a good track record, but i don't get the 4K ones
DVTel answered a few questions:
- Low light performance: "The low light is better than most 1080p’s and 45% more sensitive than the other 4K’s being introduced to the market. Also, our lens is F1.2 vs. the other 4K’s we’ve seen are F1.6 and F2.0. We are in the process of finalizing our LUX rating but attached are the datasheets for now.
- Price: "MSRP is $1680. Another key affordability factor is bandwidth/storage and our preliminary testing shows that our 4K’s with its enhancement to our advanced motion processing implementations allows it to achieve lower bit rate at 4K 30FPS then the common competitors 1080p’s at 30FPS. Another example is that our 4K’s support four simultaneous streams of 4K+1080P+720P+D1 and the VMS will choose the most optimal stream to match the client viewing surface so that it most efficiently utilizes the processing resources and doesn’t require costly PC’s.
- ONVIF S immediately and G (on board storage) later this year.
Low light and bandwidth needs to be tested. That said, We are generally sketpical of super bandwidth claims, especially because of the previous DVTel camera having the same claim that we refuted in our testing.
The camera pricing looks to be about average, but certainly not on the low end.
They are bashing 'legacy megapixel' cameras but... doesn't DVTel offer megapixel cameras too? I was almost expecting to hear them state, "and just one 4K DVTel camera can replace 29 analog cameras!"
By the way, is there any possibility you'll be testing the Quasar cameras again in 2015? Your 2012 report was really helpful. It would be nice to know if they have improved over the last couple years. The local DVTel reps claim, "Quasar cameras are best in class and offer tremendous bandwidth/storage savings while delivering arguably the best picture in the industry." Arguably? I'm not sure they're prepared to win that argument.
Although others have come out with 4K offers (Axis, Bosch, IQEye, etc.) have you come across any in dome form factor?
