A smart intercom company has offered New York City landlords a solution to help evict bad-acting tenants, allowing them to raise rents where laws and regulations would typically stand in the way.

Teman GateGuard, a company and product started by CEO Ari Teman, sent out a promotional email to landlords opening with, “You CAN raise rents in NYC!” The product is a smart intercom lock to be installed on apartment doors. A landlord would be able to see still images of people in, out, and in front of the apartment. Teman says the goal is to catch tenants acting in bad faith, such as operating illicit Airbnb’s, subletting, or having unreported roommates.
