Monitoring Capabilities

Monitoring Architecture

  • A typical monitoring architecture consists of the following:
    • Multiple Sensor Units
    • One Network Receiver (sometimes referred to as a sink)
    • One Data Appliance
    • One Acrysoft.Net account for cloud storage and viewing of data per person
  • Additional infrastructure requirements
    • Accessible physical location for the data appliance to be installed
    • Reliable power for the data appliance
    • Internet connectivity via Ethernet. At locations without Ethernet, wireless receivers and cellular modems can be provided


Data Sensors and Wireless Nodes

  • Temperature and Gaseous Properties

Our sensor units are designed to be housed within the V2T Vent and measure both relative humidity and atmospheric pressure within the top hemisphere of the vent. The units may be also modified to collect additional types of gaseous properties. Each unit can be configured to measure multiple properties assuming the corresponding sensors are available.

  • Wireless Networking

Our sensor units utilize a sleeping mesh networking technology. This allows for real world placement of units in remote locations of the roof without access to a line- powered router. It is expected that a minimum of two of the sensor units are in direct contact with the data appliance (see definition below). Sensor units should be placed in such a manner that develops redundant network pathways. Work is underway to verify that the network can operate utilizing AES encryption for concerned locations. 

  • Collection Frequency

Currently our sensor units collect information at a set frequency that is configurable. Generally our units have operated at a 5 minute frequency. The next generation of sensor units is anticipated to have more robust capabilities. The standard frequency can be modified to one of several present frequencies by an Acrysoft administrator.

Our current plan will allow the sensor unit and data appliance to respond to certain events and dynamically change the frequency. This semi-autonomous behavior will provide more frequent information when necessary.



  • System performance

Our central server is capable of flagging system faults and reducing system downtime. If communication is interrupted from either the data appliance or from an individual sensor unit, the central server can contact the appropriate personnel for that building monitoring service agreement and inform them of the problem.

  • Threshold alerts

We have planned for customers to have the capability to set threshold alerts on any gaseous property. These alerts may send an automated email or text message to the address specified in that customer’s profile.


Data Logging

  • Short term data logging on site

Our data appliance is designed to be installed on site. The purpose of this unit is to coordinate and control the wireless network, coordinate with our central server, and temporarily house data storage. Short term storage can be configurable within the physical limitations of the device.

  • Long term data logging

Long term data storage is provided via the Acrysoft’s centralized data center.  By using global SAS70 Type II certified data centers, Acrysoft strives to provide a high level of information security.

  • Reliability of data transfers

Internal controls and coordination on the data appliance strive to provide redundant and acknowledged data transfers between the appliance and the central server.

  • Installation Protocols

In order to maintain reliability during hostile conditions (e.g., hurricanes, storms, etc), Acrysoft recommends redundant infrastructure. In order to ensure communication for the data appliance, we commend installing a backup power supply for the data appliance. Similarly, we recommend installing a backup cell modem to act as a roll over fail safe when the non-cellular Ethernet connection fails.



  • A web based application exists to track the environmental data that is collected.
  • Each customer will have a unique user name and password for the system. These login credentials are associated with customer service agreements.
  • Upon accessing the system, users will have the ability to select from multiple buildings associated with them, where appropriate. Clients may view the information collected at any individual sensor unit over various time periods (last 4 hours, last 24 hours, last 7 days, last 30 days, etc). Information can be displayed tabular or graphic formats.
  • A single screen displaying the current readings or status of all sensor units for a building is also available.
  • An alert screen will be available users to view any alerts generated for their buildings.

    • Temperature Accuracy: 1.0°C
    • Operating Accuracy: +/- 3 hPa at 0 to 65°C
  • Humidity Sensor
    • Operating Range: 0 to 100% RH
    • Operating Temperature Range: -40 to 125°C

+/- 4% at 0-10% RH

+/- 4% at 90 to 100% RH


In general we believe that the V2T Vent Technology has a significant advantage in performance, installation, monitoring, environmental stewardship and cost than any other system on the market. To date, we have millions of square feet of roof in all climates that is providing these benefits to contractors, building owners, and manufacturers across the country.
