Both will work nicely in an indoor environment. Not sure if IR reflections on the dome have much effect inside as the IR usually is able to reach the far end of a room.
The other thing is the aesthetics. A dome sorta looks more appropriate inside, then a turret, IMO anyways.
If you want something that slimmer than a 2132 for indoor you can get the mini dome the 2532. Just keep i mind IR is lacking in distance (they only have 10 leds and I think a few of them are covered). Network Camera Critic has a review on this model as well.
