heres another suggestion that you may not think of
use surround sound speakers that you can fasten high up but on one speaker take out the speaker drill a hole the size of the camera been used and insert it into the hole
with black fronted speakers it looks like a tweeter speaker so most ignore it
the house is marked as an easy target the fact its been done twice is more like the robbers comming back for replaced items from the insurance claim
also anyone entering from the street will not cover up as it causes too much interest it may be worth considering some street path way cameras to catch the faces of the intruders
