It was super humid last night. Went out anyway and grabbed some footage of a nearby park at around 10:30pm. The Sidekick640 has the most recent firmware update (I believe 7July24). The update was an improvement and the unit hasn't froze yet (only 2 nights out with it).
So I grabbed some video of each panning the same area of park. The x2 base magnification of the T2 kinda sucks for up close pics, but does okay at further distances.
Keep in mind the T2Pro is 256 and the sidekick is 640.

All in all, the T2Pro isn't bad at all for a $319 thermal camera that will fit in your pocket and plugs into your phone. I will be upgrading my son's phone very soon and will use is Samsung S2 as a dedicated host for the T2Pro. Is the Armasight Sidekick640 better? IMO, yes it is. Is it x10 cost better than the T2Pro? No, it isn't. I hope that US companies can advance their thermal tech to get the same bang to buck as the Chinese thermals.
