Siren is Unidens long awaited scanner control app for the BCD536HP. The app allows you to listen to and control your scanner over a wifi link -- either a direct link to the scanner (useful for mobile applications) or over a local intranet connection.
V1 allows monitoring and control in scan mode. Future updates will continue to add more capabilities to the app.
Your scanner must be running the latest firmware to use this app. For information about the latest firmware, see http://info.uniden.com/UnidenMan4/BCD536HPFirmwareUpdate.
