The AES Audio Sentinel®+» Web is a web-enabled two channel AES/EBU silence monitor combined with an integrated 2×1 switcher. It is designed to monitor two AES audio sources, one primary, the other back-up. When silence is detected on the primary input it can automatically switch to the back-up input via mechanical latching relays. It features a browser-based HTML5 web interface and supports SSL/TLS email (Gmail, etc.), SMS-email notification, as well as SNMP.
