Thanks for your opinions.
The linked site misleads people. Wicked, all I have to say. There is no specific reason, technically, for HD-TVI to perform better than HD-CVI or HD-AHD. Let them compete each other so that end users can enjoy better quality and better price. HD-SDI, carrying video in form of raw digital, no compression, is still expensive when compared to those HD-Analogs, listed above. And CCTV is becomng Cost driven market, not tech driven any longer. So HD_SDI seems to be losing its ground.
I'm wondering if that site only trades with particular manufacturers and thus are excluding the other technologies solely for that reason.
TVI and CVI are readily available, cheap and have lots of camera choices...new installs should be IP (for most applications, that the very least run ethernet and use baluns so the system can be easily upgraded in the future)..these are transitional technologies.
I'm including analogue HD because despite a flood of no name IP cameras at very reasonable prices recently, the price difference is still very clear. For example, the linked site is pushing an 8CH TVI with cams for just under $1k, but the IP equivalent is just over $2k.
CCTV is becomng Cost driven market, not tech driven any longer.
So am I being unrealistic to rule out the cheaper brands? I posted a question where I said I thought all the DVRs now looked like generic black boxes, with poorly designed front panels.
