I am not familiar with infrared grills but I assume it is another version of the charcoal or gas grills for back yard BBQs, etc.
It seems to me that one of the primary reasons for grilling outdoors is to manage the smoke that is generated in the cooking process. Inside and without special exhaust vents you would fill your house with the smoke.
An indoor/outdoor grill - is there such a creature?? I've never heard of it but I may be wrong.
