Tenant put up security cameras, how to deal with this?

[Cody F.]

We had a tenant put up security cameras and drill into the wood of our deck to install them. We don't have anything in our lease or rules about cameras. We gave them a notice to take them down but the tenant responded that they talked to a "Family attorney" stating that our lease didn't say they couldn't put them up. They then stated their cars had been keyed twice and said "are you going to pay for the damages? "

I'm not exactly sure how to deal with this. I'm a new landlord and this is a first. All help is appreciated!
