The CircuitWerkes SiteSentry4 ushers in a new era of remote site monitoring. An internal Web server lets you monitor your site from any Web browser, anywhere in the world. Automatically detects both meter low and meter overload conditions on each channel. Combine channels to create IF/OR/AND alarm conditions. An internal temperature sensor can respond to high or low temperature conditions. Temperatures can be scaled and are displayed in Fahrenheit or Celsius. The external audio monitor meters two channels of audio and can respond if either silence or overload are detected.
Multipurpose control functions: The SiteSentry4 gives you Web control of six relays (two are DPDT) that can be latching or momentary. Two status inputs give a visual indication, via the Web server, whenever triggered & can also activate automated relay actions. Use the SiteSentry4 anywhere that you need an inexpensive, network addressable, controller with status capabilities. Three levels of user control are available ranging from reader up to administrator.
Automatic (user programmable) functions: When meter-low, overload, or external status change, is detected, the SiteSentry4 can perform user-programmed, automated, sequences of actions and can also respond to user control via the network or via external contact closure inputs. Actions can be programmed to run once or to repeat while the condition exists. Alternate actions (or cancellation of previous actions) can be set to run when the conditions return to normal.
E-mailing/SMS Texting: The SiteSentry4 supports SMTP and can send both e-mails and SMS text (to your phone) messages that alert you of alarm conditions. E-mailing is accomplished directly from the SiteSentry4 hardware. Additionally, the free software that is coming soon for the SiteSentry4 is also capable of sending e-mail or SMS messages. The software can also launch your default e-mail client (like Outlook Express) and send e-mails using that.
Dynamic DNS (DDNS): The SiteSentry4 supports dynamic IP redirect services like dyndns.org and no-ip.org. This allows you to use the SiteSentry4 on a dynamic IP instead of paying for a static IP. With DDNS, you can find your unit by name instead of by typing an IP number.
Free Upgrades: The SiteSentry4 is field upgradable. When new features are added or when a bug is found, you can easily and safely upgrade the units in the field with the latest firmware through the webserver. With free upgrades, you can always keep your SiteSentry4 up-to-date.
Up to two SiteSentry4s can be optionally rack mounted in a single sized rack shelf. Administrators can perform all setup through the web server.
The SiteSentry4 includes free multi-site monitoring monitoring software. User settings & labels can be saved to the host computer and uploaded to the original SiteSentry4, or to others for mass programming.
The “S” version of the SiteSentry4 (SiteSentry4s) includes the ability to decode Shoutcast/Icecast MP3 or Ogg-Vorbis audio streams. Stereo or mono streams are supported at bit rates up to 192kbs (no more than 128k is recommended due to an on board buffer limit of 64k). Received audio streams may be routed through the DPDT relays for putting on the air as backup sources when a main audio failure is detected. The decoder mode includes station & song name decoding for Shoutcast as well as general stream information.
The SiteSentry4 also includes the ability to encode Shoutcast/Icecast compatible audio streams using the open-source Ogg-Vorbis format. 10 different streaming profiles are included. Ogg-Vorbis can be decoded by virtually all media players and is a very robust and high quality alternative to mp3 encoding. The SiteSentry4 can be used to either encode or to decode audio streams. Because it is half duplex, the SiteSentry4 can not encode and decode at the same time. Switching between transmit and receive is a one-button click.
The SiteSentry4 can be used as a stand alone streaming audio encoder or decoder with auxiliary relay outputs, however, the SiteSentry4 relays are not synchronized with the encoded audio. Audio in and out of the SiteSentry4 is balanced, stereo, on unplug-able screw terminals.
