Does the TRV900 have “nightshot”?
No. The TRV900 is a 3-CCD camera which is optimized for the best color video. The CCDs are permanently bonded to the dichroic beamsplitter which determines the color response (and blocks most infrared). There are no 3-CCD type cameras yet available with “nightshot” capability. Most Sony single-CCD cameras have a “nightshot” mode, which gives better performance in dark conditions by physically removing the IR-cut filter in front of the CCD (used to improve color imaging in normal light), along with a built-in infrared LED to illuminate nearby objects. It is a monochromatic mode, and somewhat unnatural-looking due to the differing reflectivities of objects in the near-IR (700-900 nm wavelengths). If you want to take images of nocturnal animals, do surveillance, or any other video in very dark conditions, you need one of the single-CCD cameras that does have nightshot.
