On 10 February 1938 he was named prefect of Argeș County. After the assassination of Prime Minister Armand Călinescu on 21 September 1939, he ordered the execution of three members of the Iron Guard from Pitești, whose bodies remained exposed in the Public Garden for two days. Subsequently, he sought to have a bust of Călinescu erected in Pitești, and donated 5,000 lei towards the fund established for this purpose, but the plans were abandoned once the National Legionary State came to power. On 10 September 1940, Cameniță was appointed to lead the General Directorate of Police and State Security by the government of Ion Antonescu. On 10 May 1941, in recognition of the role he played in defeating the Legionnaires' rebellion, Cameniță was promoted to the rank of brigadier general.
