Trying to destroy my security camera

I have installed CCTV for my security purpose . Before installing i had informed the same to my society. The woman staying in next flat has tried to hit my camera couple of times. when I asked her why did you do? She denied it. Then i said it has been recorded. Her husband said it might have happen bymistakely. I Politely asked them to be careful next time bcz all the dust particles got stuck to it and it was also shaken from the side where she had hitted. Even after that she repeated the same thing again. When I asked her again She said "I was cleaning, what if the broom stick hits it does it mean I should not clean". They are the tenant and the owner of the flat lives in Thane. Our society is in Mumbai. Her intention is to harm my security camera. Her husband has political support of shiv sena and thinks she can get away with this. What should I do please guide. Should I complaint in society ? What are the other remedies.
