Hi Chris,
By all means install video.
However, tracing the felons after the event is often difficult and it won't help
if they've already trashed your car/stolen stuff.
My view is to beef up your already strong doors/fencing etc. especially if
they've breached already.
Hard steel, boxed-in quality padlocks together with thick steel doors,
maybe a roller shutter with no fixings visible.
An alarm system, via your mobile, to give instant notification may also
work well, depending on distance and willingness/promptness of the local police force.
It's always traumatic, I sympathise. In many cases, if they want in, they will achieve regardless.
Hope this helps.
Best regards, Nigel
