Abstract: Systems and methods are described for protecting a device from a denial of service (DOS) attack. The method comprises receiving, by the device, a connection request from a third-party device, determining, by the device, that the third-party device is malicious. Switching a mode of operation of the device from a first mode to a second mode, in response to determining that the third-party device is malicious, and broadcasting in the second mode, a message configured to be decoded only by a credentialed device.

Abstract: Disclosed systems and methods relate to a smart access control reader for an access control system. According to embodiments, a method can include installing the smart access control reader to the access control system by connecting the smart access control reader to the access control system via wiring of the access control system. The method can also include receiving, by the smart access control reader, one or more first credentials for authenticating one or more users by the access control system. The method can further include determining, by the smart access control reader, that the one or more first credentials are authorized. Moreover, the method can include transmitting, by the smart access control reader, a second credential to an access control panel of the access control system, in response to a request by a first user to access an area monitored by the access control system.

Abstract: Systems and methods for occupant and guest interaction with a virtual environment are provided. Disclosed systems and methods enable occupants to create an event associated with a particular location in an area within a virtual environment. Graphical interfaces and display methods can display interactive event markers overlaying images of the area within the virtual environment.

Abstract: Disclosed systems and methods relate to a smart access control device in a security system for monitoring an area. According to embodiments, a method can include receiving, by the smart access control device, from one or more sensors in the area, sensor data about the area. The method can also include analyzing the received sensor data and generating an alert for a user about the area based on the analyzed sensor data. The method can further include transmitting, by the smart access control device, a first signal comprising the alert to a monitoring server of the security system. Moreover, the method can include enabling, by the smart access control device, a person requesting access to the area to enter identification information and granting access to the area to the person based on the received identification information that is evaluated by the user.
