The present disclosure improves security in a technology for unlocking an electronic lock using a door phone slave unit. A business phone main unit (2) includes: a PB signal reception unit (22) that receives a PB signal input through a door phone slave unit (5); an authentication information decoding unit (23) that decodes authentication information from a PB signal; and an electronic lock control unit (25) that controls an electronic lock (4) based on the decoded authentication information.

A programmable signal generator and radio controller for providing dispatch paging tone out frequencies to first responders and other selected areas. The signal generator is capable of performing tone-outs to various first responders and being cross compatible with prior and future evolutionary systems. The signal generator uses plain-text console interface and plain-text tone-out parameter definitions allowing programming without special software, apps, or Internet connectivity. The signal generator is capable of controlling operational functions of connected radio transceiver equipment including initiating and terminating RF transmission, selecting radio channel or frequency, and monitoring operational status of the transceiver. The signal generator is also capable of interactive communication with external third-party digital radio dispatch console systems via Ethernet network and TCP/IP protocol via an isolated network interoperability interface that implements a simple Application Program Interface (API).

An audio/video (A/V) recording and communication doorbell, including a camera, a speaker, a microphone, a power manager, a battery, an AC/DC rectifier, and a DC/DC converter. The doorbell is configured for connection to an external AC power source through the AC/DC rectifier and the DC/DC converter. The power manager is configured to draw power, up to a threshold power, from the AC power source and to draw supplemental power from the battery such that the power drawn from the AC power source never exceeds the threshold power. The present A/V recording and communication doorbell can thus be connected to an existing household AC power supply and an existing doorbell signaling device without causing inadvertent sounding of the signaling device.

A method is presented. The method includes receiving a trigger for establishing an emergency call at a first vehicle and determining, in response to the trigger, whether a communication system associated with the first vehicle currently has access to a first wireless communications network. The method also includes searching for a second wireless communications network when the communication system currently does not have access. The method further includes searching for a second vehicle with peer-to-peer wireless access capability when the second wireless communications network is not found. The method still further includes transmitting vehicle related data to the second vehicle via the peer-to-peer wireless access capability when the second vehicle is found.

In some embodiments, the present invention provides for a computer-implemented method, including: causing, by a specifically programmed computer call management communication system, to transform, over a computer network, computing devices of users, into corresponding specialized call management devices, by having each computing device to execute a specialized call management client software application being in electronic communication with the specifically programmed computer call management communication system over the computer network by utilizing SIP; where the specialized call management client software application generates specialized graphical user interfaces configured to allow each user to concurrently initiate and maintain, over the computer network, a plurality of voice communications of distinct types with other users, by, for example, allowing each user to independently and dynamically divert, in real-time, any voice communication of any type to any audio device associated with a corresponding specialized call management device of such user.
