Broadcast Tools Audio Sentinel Web-Based Stereo Silence Monitor

Product Description

The Audio Sentinel™ is a web based dual channel stereo silence monitor combined with a transparent, integrated audio switcher. Audio Sentinel™ is designed to monitor two balanced or unbalanced independent stereo analog audio sources and switch to a back-up analog audio source when silence is detected. The Audio Sentinel™ can be controlled and monitored locally and/or remotely over any IP network, including private networks, IP-based industrial control networks, and the Internet. Users can operate the product using a web browser or web-enabled mobile device. Email notification may be configured to alert up to four recipients when alarms are detected. The user may also enable a sound effect to play on their PC speaker when an alarm is generated. Logging of system status, along with the site ID may be emailed in time spans from once an hour to once a day. One SPDT relay is supplied to indicate which input channel is feeding the output, while two additional independent SPDT relays may be configured to perform user defined logic functions. SNMP and SMTP username and passwords are also supported.
