viewLinc Monitoring, Alarming and Reporting Software

Continuous monitoring for temperature, humidity and other parameters

The viewLinc Enterprise Server software monitors temperature, relative humidity, CO2, differential pressure, level, door switches, and more, offering low cost of ownership due to easy connectivity to your existing network, remote access, and scalability up to thousands of monitored locations. Multi-site monitoring is simple, global systems can be run off a single server location.

viewLinc software

As the software component of the Vaisala environmental monitoring system, viewLinc provides alarming, real-time trend data, and reports for compliance with GxP regulations. With Vaisala's industry-best sensors, viewLinc monitors temperature, relative humidity, CO2, differential pressure, door switches.  viewLinc also supports Modbus transmitters, allowing you to incorporate unlimited parameters into viewLinc: particle counters, flow and liquid measurements, and other sensors.

Ideal for multi-site and parameter monitoring, with a capacity of thousands of locations, viewLinc is used in diverse environmental monitoring applications. The software combines an easy-to-use Web-based interface with highly accurate devices that can be networked by any combination of connectivity options: Ethernet, PoE, Wi-Fi, or Vaisala's proprietary long-range wireless technology VaiNet.

Key benefits

User friendly software, real-time data & alarming

Secure web-access to real-time trends and graphical overviews of all monitored locations. viewLinc's learn-as-you-use interface guides you through tasks and functions. Tours introduce you to common features, saving time and levelling the software learning curve. Drill down into monitored areas in a dashboard view to see data for your devices over any time period. Receive alerts on monitored environments through email, SMS, voice calls and alarm towers.


Data integrity ensured

viewLinc preserves data integrity in many ways. Months of data can be retained in data logger memory, depending on the device model and sample interval. Onboard power and memory in the measurement devices preserve all existing data and ensures measurement continuity during network or power outages. Data is automatically transmitted to the server once connection to the network is restored. Measurement data is then saved to a secure, tamper-proof database on the server.


Easy to deploy and use

viewLinc 5.2 software and hardware install easily and connect to an existing network via a combination of connectivity options, including Ethernet, Power over Ethernet, Wi-Fi, or VaiNet - Vaisala's long-range wireless technology. Monitoring devices self-identify within the software and come with simple configuration templates. Interface tours guide users through common tasks, providing onscreen guidance and embedded tooltips provide immediate user assistance.
