Zenmuse XT Is a FLIR camera that's mountable on the Inspire 1 (not I2) and Matrice 100 . The new Matrice 200 msinger linked (dual gimbal version) is apparently campatible with the XT camera as well, but I haven't seen the adaptor they're using in the promo materials so who knows -- maybe it's a whole new FLIR camera also campatible with the Inspire 2 mount.
Camera (XT 640 30hz 13mm) will be around $11K. You can get a slightly cheaper version but you are getting less resolution and performance too.
The M210 aircraft is $8K - $14K depending on which model you get. That's before multiple batteries, high end chargers, carrying case and other "needed" goodies.
Our County is putting the proposal together right now to get the M210(nonRTK) and dual camera setup. We're sitting at $25K with no bells & whistles.
