Web cameras are to be installed at all polling booths during the by-election to the Tiruchi West constituency.
Collector and district election officer Jayashree Muralidharan said on Monday that monitoring of all the 240 polling booths would be carried out through the cameras.
The Collector initiated the second phase of training for college students roped in for recording the poll proceedings.
Though web cameras were hitherto installed only in sensitive booths, intensive monitoring has been extended to all the booths at the insistence of the Election Commission, she said.
Services of 285 MCA, M.S. IT, and M.Sc. computer science students from Jamal Mohamed College, Bishop Heber College, Holy Cross College and Kurinji College would be utilised.
Poll proceedings would be monitored simultaneously by the district election officer, Chief Electoral Officer and the Election Commission of India.
