The thing is MM, top-quality 1080p will be better than cheap 4K (and by cheap I mean sub $1000). None of our 2MP/3MP/4MP stuff is anywhere near as good as SD TV.
I don't want people getting sucked into that more megapixels is better marketing stupidity.
One thing I forgot to mention is price. Obviously 4K stuff cost more than the typical 3MP and 2MP stuff.
That argument works for everything really. I do get where you are coming from. Its the typical thing with cameras on phones and when point and shoots were popular. The megapixel war was what I call it, where manufacturers were trying to release cameras with a higher number. Because everyone as you know believes bigger is better. I have a Sony W50 camera that's 6mp it takes heaps better pictures than cameras with 13mp and etc, in some cases the 6mp sensor was larger than the ones with 13mp.
The other thing with that is some manufacturers don't even use a real 1:1 sensor as in 13mp camera has a 13mp sensor. They would use a smaller sensor and interpolate the image to make it larger.
For the stuff about our cameras are not as good as SD television or even HD television I never said it was. The commercial grade cameras they use for broadcasting cost easily $15k or so. I'm not into broadcasting equipment or even video cameras as I mainly do photos. Also the lenses on those cameras can cost more than the camera alone. Same goes for SLRs/DSLRs optics play a huge role, you could whack an expensive lens on the cheapest DSLR canon make and turn out great photos compared to an expensive 1D for example with a cheaper lens (although you can't really get too cheap on a EF mount).
Video that was recorded on 'high quality' equipment that is then re-encoded and resized into a stream into our television still looks heaps better than one shot at that lower resolution. Reason being is that quality was never captured in the first place. In the ones where it's been re-sized and etc the detail was there, it has just been distorted.
Another thing is resolution doesn't exactly equal image quality. Many people don't know what. It just allows you to blow up the image more eg when printing a photo. With a high quality image you could blow it up quite large without much distortion. Perfect example is those large LCD screens that still run only at 1920x1080p the pixels are bloody huge. If you get that same 1920x1080p signal and put it into a smaller screen with a higher PPI the image would seem soo much clearer.
Pixel size, density, noise, low light performance and etc all come into play as well.
Now at the end of the day. We can't bag the 4k stuff yet, for one we have not seen what it is like. It could be good it could be crap. Could even be a 3MP sensor that has been 'digitally' enlarged to give us a 4K output (although that'd look pretty shit). 4K stuff is in-progress at the moment especially for 'cheap' IP cameras, so I'll take progress over staying the same.
Anyways just my 2 cents. (can't get you much these days)
