Oh poo.
Get laminated glass put into all outside doors and windows, not safety glass like you have had broken.
They can break the glass but cant get a hand in and its better for you to if you accidentally break the glass, no glass bits spread everywhere,
but now you will be finding it for years in odd places.
The builder chose safety glass because it is so much cheaper than laminated but fits 'Standards'.
Some security cameras up around the outside and in at entry's, facing the doorway, and security lighting, signs for security installed even if you dont have it
and signs for 'dog enter at your own risk' on the outside fence.
Stereo or TV playing also worries them - sounds like someone is home.
Alarm system too if you need it, people forget you have an SOS facility with them, press a button, alarm noise and '000' call, usually they piss off quick if it's
just a home tossing and not a personal attack.
There are wireless alarm types if you are renting.

I have their 4 camera system it is the same and is easy to install and connect up, worked perfectly 1st time, not top end but at $299 it is not bad at all
In SA you can defend yourself if 'you are in fear for your life or protecting someone elses'.
In the dark you may have thought you saw a weapon.
This stuff leaves you feeling 'invaded' and angry.
Sorry it happened to you and as you said, better you were home than just your missus.
Best of dude.
