Across April and May, Devon and Cornwall Police issued 989 fixed penalty notices relating to breaches of coronavirus rules.
A quarter of the fines issued between 1 April and 28 May were given to people outside of Devon and Cornwall.
Over the bank holiday weekend, 50 fines were issued and of those, 38% were for overnight stays including in campervans and second homes.
During the bank holiday, officers carried out high visibility patrols at over 900 locations.
ACC Glen Mayhew said: “Officers have used discretion in each and every situation to engage, educate and encourage before using enforcement as a last resort where necessary."
He said working with the community to shape the force's approach has been "a crucial part of this process".
“Many of you told us that you were concerned about second homes and overnight stays so that was an area we focussed on, particularly since the changes to lockdown earlier this month."
ACC Mayhew thanked the "majority of people" who continue to follow the rules.
