Our analysis shows that V211 is a typical Algol-type binary and NV358 is a well detached binary system. As the two binaries are definite proper motion members of omega Centauri, we estimated their physical parameters, obtaining M_1=1.13\\pm0.03M_\\odot, R_1=0.98\\pm0.01R_\\odot and M_2=0.33\\pm0.01M_\\odot, R_2=0.92\\pm0.01R_\\odot for V211; M_1=1.30\\pm0.05M_\\odot, R_1=1.03\\pm0.01R_\\odot and M_2=0.58\\pm0.02M_\\odot, R_2=0.78\\pm0.01R_\\odot for NV358.
