Visitor entry phone systems provide a convenient and secure way to allow guests into a building. In a residential building typically the lobby and elevators will be locked off. A guest or delivery driver can use the entry system to speak with the resident and upon authorization with the press of a button a resident can conveniently allow them access into the building both through the lobby door and unlocking the specific elevator floors. Similarly, in an of commercial office tower visitor entry phones are most often used to allow guest access after-hours. For example, a building may have its lobby doors and elevators unlocked from 8am to 5pm. After hours tenants will use their cards or fobs for entry. Should you have a meeting with customers or contractors outside of business hours or on a holiday/weekend a visitor entry system provides a simple and convenient way for a guest to access your office floor.
