They are Ultra's not cheap, IPC-HFW8630E-Z | Dahua Technology
but they have a 1/1.8" sensor, much bigger than a 4MP 1/3" sensor and they are backlit Starvis using same tech as these Starlights..
A big problem with all the UHD Sensors right now is none have real WDR, I've found DWDR is rarely adequate for many outdoor environments with alot of shade and bright light in same scene.. at least for security needs where getting detail on shaded faces is more important than true blacks and ideal color reproduction.
