In the first round of the count, he received the most support with 55,257 votes, 28.05 per cent, followed in second by Brian Greenslade, who gained 24,719, 12.54 of the votes.
After the second round of the supplementary voting system, where second choices are taken into account, Mr Hogg received a total of 69,419 votes, ahead of Mr Greenslade who had 37,243.
Mr Hogg, who spent 30 years in the Navy, described himself as "greatly honoured" to have won the poll despite the turnout of just 15 per cent across the region.
He said: "I genuinely believe in this pioneering role and look forward to the challenge. This position has been established to give people a voice in deciding their policing priorities, and I will be listening. For the first time residents can hold someone directly to account at the ballot box for the way in which their community is policed.
"Whatever your views on the election or turnout, I am committed to serving everyone in Devon, Cornwall and the Isles of Scilly. This is an exciting opportunity for everyone to get behind this new role, to get involved to help shape future priorities and work together to make a real difference. I'm here to get on with business and work hard. People will expect me to work closely with the chief constable to get things done and that's exactly what I plan to do by helping people feel more connected and engaged with the Police and Crime Plan. People want value for money while maintaining safety and I will do everything within the powers I have been given to ensure the resources are there to do the job and meet priorities. "The task in hand is not something that can be achieved overnight. It will take time to review areas for improvement and I will be listening carefully to ensure that the issues that matter most to people are dealt with."
Mr Hogg, who was formerly the commanding officer at Culdrose Royal Naval Air Station and served in the Falklands and Gulf, will have to appoint a permanent chief constable and publish a Crime and Police Plan by March 2013.
