Doorbell cameras can be used in apartments as long as the building management allows them. Most doorbell cameras are designed to work with traditional doorbell wiring, which may not be available in some apartment buildings. However, some doorbell cameras come with a battery-powered option that allows for easier installation without the need for wiring. It’s important to note that tenants should check with their building management before installing a doorbell camera to ensure that it’s allowed and doesn’t violate any rules or regulations. Additionally, since apartment buildings often have shared entrances, it may be necessary to coordinate with other residents to ensure that everyone has access to the footage.
