Cameras for Cube Orange

I am currently using a MapIR camera for search and rescue operations but I’m always on the lookout for something better. I have found that its hard to beat, does anyone know of a camera that has a higher mega pixel rating but has all the bells and whistles that a Survey 3 MapIR camera has? I’d like it to be affordable, say less than $700 USD.

A close second would be this ADTi camera but they are pricey, I think the 20MP version is 800-ish.
