Any time a problem exists where we need coverage in Low Light situation we have turned to the Hikvision "Dark fighter" and problem is solved. Have used these in LPC situation also with great success.

With the cost being so prohibitive, you might as well buy a couple of extra Hikua adaptive IR cameras just to use as external illuminators. 50M ~ $100

It's too bad nobody makes a camera with built-in IR that takes full advantage of the 15.4 watts available over PoE (or the 30 watts on PoE+). Most of the cameras I see use approx 5 watts in day or 7 watts at night with IR on. So I take this to mean that IR consumes 2 watts. What about taking the 7-8 extra watts available on PoE and adding more IR or more powerful IR? Has any manufacturer taken this approach that you know of?

With IR both dahua and hik have long range ir models of 150-200ft in stanard cam and up to 2400ft in ptz. I think that is enough for most requirements.
With low light i believe dahua starlight is superior to hik darkfighter. I do work for dahua though. :)
