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.
Add
Web monitoring and control to an
existing dial-up controller
Not only are the SiteSentry series of
remote controls great little stand-alone
remote controls, they can also be used as
a convenient way to add Web/network
capabilities to your existing dial-up only
remote control. If you have a
dial-up remote control or a product where
the Webserver is no longer supported, you
don't have to get rid of your old
hardware. Simply parallel the
SiteSentry's metering inputs across the
desired metering channels of your old
remote control and also wire in the relay
outputs in parallel, too. The
SiteSentry will work in parallel with most
older remote controls to provide a rich
Web experience complete with independent
alarm handler, NTP corrected real time
clock and event scheduler, logging with
emailing, and email/text message alarm
notifications. Now you can upgrade
your old remote control's capabilities for
a fraction of the cost of replacing
it. The SiteSentry series of
controls do not use Java, ActiveX
or any other proprietary software.
Your SiteSentry unit will work on nearly
every browser and across all major
operating systems including Windows,
Apple, Android and many others. Only one
port is needed to access the Webserver.
Multi-purpose
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. Action
sequences can also be run manually.
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.
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.
Onboard Clock
with DST Aware Event
Scheduler
The
SiteSentry4 can track time using an NST
time sync but will continue to keep time
even if no NST server is
available. Manual time sync is
also permitted. In addition,
a 50 event scheduler is
included. The scheduler has
a resolution of better than 1 second, so
events can be scheduled at any second of
any hour. Events can be set to
repeat every day at a specific time for
a month, then stop but to repeat again
the next year (for AM station
pattern/power changes).
Automatic
Logging
Onboard
logs are kept at a user specified
interval. Logs can be e-mailed at
regular intervals. Logs can also be
included with alarm e-mails, if
desired. The log format is
user-defined via a two-part template.
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 Webserver.
Streaming Audio
Option (In or Out)
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 bitrates up to 192kbs (no
more than 128k is recommended due to an
onboard 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 deplugabble screw terminals.
