The four crimes took place overnight between February 4 and 5.
One property was entered by an insecure downstairs window. Nothing is believed to have been stolen.
A about 3.15am a second property was entered through an insecure door. One of the occupants heard the door open and challenged the intruder who fled out of the rear door and round the side of the house.
