Hi Jeff,
Firstly, I'm sorry to hear that you've suffered a break-in
It's virtually impossible to make anything completely vandal proof.
Where possible, it's good to arrange your cameras so that they cover each other.
'Safe by position' is another option that we talk about e.g. place your cameras high up / out of reach.
But of course you need to exercise some balance in this respect, as if they are fixed too high you may not gain useful video evidence anyway, tops of heads aren't usually very useful.
The cabling then tends to be the weakest point, so if you can keep that enclosed and protected that's probably as much as you can do.
You can use conduit to protect the cabling.
Where possible, a rear cable entry through the camera's base or a mounting arm tends to be most effective, as there is literally no cable evident to see and attack.
If there's a history of vandalism, then the vandal-resistant domes are probably the best solution.
They are THE toughest camera type.
However, domes can be problematic with dust and rain build-up, and generally we'd prefer to use a turret-type camera for its better performance.
Turret cameras are almost as tough as domes; they tend to have a metal body, but the glass windows over the lens and IR may not be tough.
Unfortunately, it remains a fact that whatever you do almost any camera can be disabled by spray paint, so there's a limit to the lengths it's worth going to I'm afraid.
