A 1  k  ×  1  k CCD camera is designed, implemented, and tested for the CSTAR2 telescope in Antarctica, including its mechanics, CCD controller, and low-noise power system. In the design of mechanics and electronics, low-temperature environment is taken into full consideration. The camera has demonstrated mechanical and electrical stability. The system readout noise is as low as 3.99  erms− when the CCD readout frequency is 100 kHz. Every part of the camera is fully tested in a cryogenic refrigerator (−86  °  C) and proved that the camera has the ability to work in Antarctica for a long term. Finally, the camera is installed on the CSTAR2 telescopes to take observations and the imaging function is well implemented.
