Frequently Asked Questions
















Q: What sensors does iWatchTM work with?

A: The iWatchTM sensor display and alert software is vendor neutral.  The sensor vendors we use most often are manufactured by Point Six Wireless, however iWatchTM can be configured to accept any sensor Universal Data Packets (UDP).  iWatch is an ideal sensor data collection program allowing orphan sensor data to be collected and managed.


Q: What happens if a sensor goes offline?  Can iWatchTM accept manual entries?

A: Yes, in the event of a sensor going offline for scheduled maintenance or malfunction, the iWatchTM system can accept manually entered readings until the sensor can be brought back online.


Q: What 802.11 security protocols do your sensors support?

A: Currently our sensors support WEP-128, WPA-PSK, WPA2-PSK, and WPA/WPA2-PSK mixed mode. 

        Note: WPA2-PSK AES is not supported.


Q: What networks do the sensors support?

A: The sensors can work with 802.11b and 802.11g networks.


Q: How much bandwidth do the sensors use?

A: The sensors send a 73 byte data packet every 5-10 minutes.  The bandwidth requirement is insignificant in most implementations.


Q: Can minimum and maximum temperature ranges be set?

A: The iWatchTM software  enables a user with a sufficient security level to set minimum and maximum data ranges for each sensor as well as a out of range duration in minutes.  If a sensors data reading falls outside the set range for more than the out of duration time period an alert is generated.  Alerts can be sent via SMS text message to cell phones and/or via email.  


Q: Do you provide a hosted service / Software as a Service (SaaS) for your iWatchTM software?

A: the iWatchTM software is available as a hosted solution / Software as a Service (SaaS) as well as a licensed software application.  Most of our clients opt for the hosted solution when getting started since it requires no server or software installation and clients can be up and running in 10 minutes.  For clients looking to purchase the software the iWatchTM software license is licensed based upon the number of sensors managed and includes is available with a annual software maintenance and support service that includes periodic upgrades and enhancements.


Q: If I start off with a hosted system can I later choose to purchase the iWatchTM software and move the existing data in-house?

A: Absolutely.  That is why the hosted solution is so popular.  It allows clients to start out with a small initial investment and later install the iWatchTM software in-house when it makes sense.


Q: Can the sensors be used for ultra low freezers?

A: Yes.  The sensors can use a standard range tethered sensor good for -50C to 125C or an extended range tethered probe good for -200C to 125C.  Thermobuffer sensors are also available with the sensor enclosed in a liquid filled vial (-50C to 125C)


Q: Is the iWatch system FDA CFR 21 part 11 compliant?

A: It is not possible for any software system to offer a turnkey FDA CFR21 part 11 compliant system since compliance requires both client procedural controls coupled with the vendor system.  

The iWatch software does offer features that support these controls such as tamper-proof data storage, change tracking, electronic signature support.   SMGs goal is to create and sustain a sensor data software storage system that is auditable to support any type of compliance audits including 21CFR part 11.  The team at SMG is committed to working with our clients in enhancing the iWatch system support when additional features might be of value.


Q: Do you work with cellular routers?

A: Yes.  We have worked with MOXA OnCell cellular routers for locations that do not have existing DSL or Cable modem Internet access.  This is a good solution for remote sites that do not have ready access to an existing Internet connection.
