A system and method for remotely monitoring and controlling building security are provided. A controller is communicatively coupled to security devices of a building and can communicate an activity event detected by one of the security devices to a remote user device. The controller can then establish a communication session between the remote device and a security device via the controller, thereby allowing the user to communicate with any visitors. Video from a security device can be transmitted by the controller to the user device or an alternative user-device. Access instructions can be provided by the user, in response to which the controller can deactivate various building security measures. Security measures can be reactivated by the controller automatically or in response to a user command. Additionally, the controller can monitor visitor compliance with the deactivated security measures and activate alarms or notify security agencies if necessary.
