Despite only renting for two months, this tenant's aggressive behavior is creating a hostile living environment for other residents.Specific Issues:He complains about our lack of notice when entering the property during our own move, despite prior notification.He has moved items around the house without permission.His communication has been condescending and confrontational.He installed a surveillance camera in a common area, violating the lease agreement.He banged on the door because he couldn't use the smartlock code properly.Considered Actions:We plan to serve him with a notice to vacate.We are considering having a constable with us when we serve him the notice.Questions:Should we just give him warnings considering that his actions may not improve?

I agree with Laura, if this is a long term rental it would be hard to convince the tenants that they have cameras on the property that the owner controls even with all the stuff that you mentioned (does not turn, only for surveillance for crimes etc.). 

"Dusk-to-Dawn" electric eyes and timers can be helpful, but don't replace personal surveillance. 

For both tenant and landlord peace of mind, the property had an extensive video surveillance and security DVR system already installed by the prior owner, which covers outdoor areas and indoor common areas and records 24/7/365, as well as sensors for excess dB noise levels.

Quote from @Carlos Ptriawan: These are the actual surveillance asset condition from one pool of CLO from one the bridge-lender mentioned above , look at AS-IS DSCR.It's game over buddy, the status of their loan is 100% in trouble with 3 in watch list and most is at loan extension, to get loan extension the GP may ask for capital call for further reserve. 

During 2025 and 2026, construction activity under surveillance is projected to deliver a total of 21,982 units.

We will have heavy surveillance with video cameras on 30 foot poles in multiple locations.

Whether it is litigation or surveillance I would do whatever it takes to protect yourself and your investment 

During 2025 and 2026, construction activity under surveillance is projected to deliver a total of 2.8 million square feet.

During 2025 and 2026, construction activity under surveillance is projected to deliver a total of 14.6 million square feet.
