If it's a mirrorless camera with interchangeable lenses, an infrared filter is sometimes part of the glass stack in front of the sensor. In some types with integrated lens, these filters can move aside. All Sonys of this line (DSC 515, 717 and 828) could go to an infrared nightshot mode. But using slow glass and the complaining "oh, doesn't work well in dark situations" is kind of stupid.
