Abstract.Here, we describe an implementation of an electron-multiplying charge-coupled device camera to search for seismological activity in white dwarfs (WD). The equipment was installed on the 2.12-m telescope at the Observatorio Astronómico Nacional San Pedro Mártir, Baja California, México. We have determined the proper operational regime to keep a very low noise while maintaining a high gain. We have also developed software for the instrument control system and data processing. Finally, we report the first results on the seismological activity of WD, obtained using photometry with one-second exposure. The results were compared to the known variables LAMOST J004628.31 + 343319.90 and GD 66. The WD 2255-001 showed very weak periodic activity with a dominant frequency of 67 mHz.
