Taiwan Meteor Detection System(TMDS) is a joint platform under a collaborative development among National Dong-Hwa University (NDHU), National Central University (NCU) and Taipei Astronomical Museum (TAM). This system is aiming to scope meteor events in the sky surrounding Taiwan and perform successive analyses of recorded events. Currently, four observing stations have been well established at Lulin observatory of NCU, Kenting observatory, Hutian Elementary school inside Yang Ming Shan National park and Fushoushan farm, respectively. From Jan 2017 to Jan 2018, the TMDS has detected 4710 events, among them 74 meteor orbits are determined. In addition, we have captured 45 events with spectra of meteor illuminations. The obtained spectra are furthermore analyzed to identify the compositions. In conseqence, several possible elements are arggested. Moreover, we have applied the Southworth-Hawkins criterion (DSH) to determine the orbital features and parent bodies of events with orbits during the 2017 Geminid meteor shower period (12/04/17-12/17/17).
