What type of lockset for a shared entry door in a multi unit

[Ames Foley]

I have an 8 unit apartment building that has two separate entrances (one for each 4 units) and each side has an internal door to the basement where there is laundry and extra storage.  This past week I had the laundry units vandalized and destroyed for the change boxes.  Some of the tenants are concerned about their safety.   I will be installing new security cameras around the area but that will only capture what has happened.  i am researching what I should do about lock sets for the shared doors.  Can I get some feedback about what others have done.  I am looking at storeroom locket on the front doors and basic two sided key lock for the basement door.  that way each side is secure.  Is there another, better way so that tenants don't get accidentally stuck in the basement?
