Abstract
A gunshot detection system includes gunshot sensor units and a control panel. The gunshot sensor units generate audio data and encrypt the audio data using an encryption key before storing the audio data and/or sending it to the control panel. The control panel decrypts received encrypted audio data using a decryption key. The encryption keys might be programmed at the control panel and distributed to the gunshot sensor units. The control panel would also store decryption keys for decrypting the audio data from each of the different gunshot sensor units. An additional layer of end-to-end encryption is provided for messages exchanged between the devices. The gunshot sensor units can also be equipped with wireless interfaces for communicating with the control panel over a communication network. To address potential bandwidth issues, the gunshot sensor units determine current network conditions and compress the audio data based on the current network conditions.
