Wireless communication security system

摘要

An event venue, such as a sports stadium, can use a security system to wireless communicate about security issues. The event venue may have one or more wireless transmitters with transmission zones within the event venue. When a central security office system receives a security alert from a device belonging to a security guard or an eventgoer, or from a law enforcement or first responder network, or from security cameras or emergency beacons (e.g., a fire alarms), information detailing the security issue can be composed into an electronic message, which may include camera footage. The electronic message can then be sent out to at least a subset of the devices in the event venue using the wireless transmitters, for example to summon security guards to deal with a brawl, or to warn eventgoers of a fire.

1. A method for event venue security, the method comprising:
receiving a security alert identifying a security issue at an event venue; identifying an issue region of the event venue associated with the security issue, the issue region being one of a plurality of distinct regions of the event venue; identifying a transmission region of a first wireless transmitter, the transmission region including at least a subset of the issue region of the event venue and including a plurality of mobile receiver devices and a camera device, wherein the first wireless transmitter is a visual light communication (VLC) transmitter that is distinct from the plurality of mobile receiver devices and the camera device, and wherein the plurality of mobile devices is distinct from the camera device; transmitting a camera trigger from the first wireless transmitter to the camera device, thereby triggering the camera device to start recording a camera feed; generating an electronic message identifying the security issue, the electronic message including the camera feed; identifying a set of authorized mobile receiver devices that includes a subset of the plurality of mobile receiver devices; securing the electronic message, thereby allowing the set of authorized mobile receiver devices to read the electronic message and prohibiting a remainder of the plurality of mobile receiver devices other than the set of authorized mobile receiver devices from reading the electronic message; and transmitting the electronic message from the first wireless transmitter to the transmission region, thereby outputting the electronic message at the set of authorized mobile receiver devices but not at the remainder of the plurality of mobile receiver devices.
