This report describes technical results obtained with   the Arcetri near-infrared camera, ARNICA, mounted at three   different telescopes from 1995 to 1998:   TIRGO, the Nordic Optical Telescope, and the Vatican Advanced   Technology Telescope.

For each telescope,   we present estimates of the camera + atmosphere efficiency,    point- and extended-source sensitivity,   telescope emissivity, and mean atmospheric extinction coefficients.   We also use data from January, 1995 to January, 1998   to analyze ARNICA's bad pixels and their change with time.
