Abstract: A lock box including a main body, a lid, an electronic locking mechanism, a lid sensor, and a processing circuit. The main body defines a compartment. The main body is structured to be secured within or secured to a substantially permanent structure. The lid is positioned to selectively enclose the compartment. The electronic locking mechanism is positioned to selectively lock the lid to the main body. The lid sensor is configured to detect at least one of an attempt to open the lid or opening of the lid. The processing circuit is configured to generate an alert in response to the lid sensor detecting the at least one of the attempt to open the lid or the opening of the lid.

Abstract: A system includes a remote server and a device having a wireless transceiver, microphone, and processing circuit. The processing circuit is configured to monitor the microphone for a siren signature. The processing circuit is configured to use the wireless transceiver to send information to the remote server in response to a detection of the siren signature. The remote server causes wireless cameras located near the device to capture a current image and to send the captured image to the remote server for further distribution.

Abstract: A method of communicating between a wireless security device and a security server through an access point includes estimating a link latency between a time of transmission of a message from the wireless security device and a time at which a response is received from the security server. A polling mode is enabled in which the access point will hold messages received by the access point that are directed to the wireless security device while the device is in a sleep state, without discarding the messages for a threshold period of time. The wireless security device may be placed in a sleep state and woken after a wake time determined based on the estimated link latency, and receives any messages received by the access point during the sleep state.

Abstract: A method of securing communications between a security device and a security server include receiving, at the security server, a registration request from the security device, the registration request being encrypted using an initial registration key. A device identifier and rotation key unique to the security device are transmitted to the security device. A first session key request is received at the security server from the security device, the request being encrypted using the rotation key. A first session key is transmitted to the security device in response. One or more communications, encrypted using the first session key, is received at the security server from the security device. A second session key request is received at the security server from the security device after the first session key has expired, the request encrypted using the rotation key. A second session key is transmitted to the security device in response.
