octavia vrs tfsi 2012 alarm questions

Hi guys I've just upgraded from a mk1 AUQ Octy 1.8 to the above. It has a factory alarm. I know according to the manual it works on volt drop and interior sensors near the interior light. Does anyone know if it has a shock sensor and is the sensitivity adjustable? The only reason I ask is where I live my @#$*€¥ neighbours hit my old car 8 times and didn't own up. Once they completely smashed the drivers door in resulting in me replacing the whole door. There was no alarm on the mk1 and I'm not worried about theft as such. I want to know if someone reverses into my car again. I'm an electronic engineer so I can retro fit a shock sensor easily with adjustable sensitivity but do I need it? I haven't resorted to kicking the tyres as yet. Any help would be much appreciated cheers

Sorry forgot to add it's still under manufacturer original warranty so I cannot invalidate it by messing with the alarm. Anything I add will be removable and probably plug in to the cigar lighter.
