At the end of voting, the electronic voting machines (along with VVPATs) are kept in designated strongrooms, which are sealed with double locks. This process is done in the presence of candidates and observers of the Election Commission of India. CCTVs are installed in the strongrooms and they are also guarded with security provided by the Central armed police forces round the clock. Candidates can send designated agents or present themselves at the strongroom for vigil as well.
