Longwatch adds Thermal Imaging to Video Surveillance Software
Thermal images appear on HMI/SCADA screens for process monitoring
Norwood, MA—February 11, 2009— The Longwatch Video Surveillance System now has an
interface to FLIR’s A-Series Thermal Imaging cameras, so that thermal images can be viewed on
standard HMI/SCADA software, such as Wonderware InTouch or GE Fanuc iFix. This capability
expands process monitoring, maintenance and process diagnostics, because the thermal images
allow operators to see product/utility leaks, “hot spots” in a process, imperfections in finished
goods, and other anomalies. Infrared imaging can also be used for intrusion monitoring.

Thermal imaging has been used to analyze processes and for security purposes for years, but
such systems typically have been specialized, stand-alone or handheld systems. Now, Longwatch
enables real-time thermal images to be displayed on HMI screens in the control room, integrated
with process displays, so operators can see what is happening in a process or on an assembly
line. Thermal images can be displayed side by side with video images on the same screen, for a
complete picture of the process.

The FLIR thermal cameras connect to Longwatch Video Engine software, installed at strategic
sites in the plant, next to process equipment, and along automation assembly lines. The video
engine continuously records images from multiple thermal and standard video cameras onto a
local disk for up to 30 days, and sends “video clips” over the plant network to the Longwatch Video
Control Center (VCC) in the plant’s control room. The VCC then sends the clips to HMI/SCADA
software, a cellphone or PDA, and stores them in a Video Historian. Clips can be sent on a regular
scheduled basis, on command from the HMI/SCADA system, when a process or assembly step
occurs, or in real time when an alarm occurs. The Longwatch system also enables cameras to be
located in far remote regions, communicating back to the central control room over a variety of low-
speed or high-speed networks.

The thermal camera and the Longwatch software at the remote site can be configured to alarm
when pre-defined temperature conditions are detected, such as if a steam leak occurs or a process
becomes too hot or too cold, or if an unexpected image appears, such as an intruder. The system
can retrieve thermal images from before the incident occurs—such as 30 seconds before the
alarm—and immediately send a video clip to the operator when the alarm occurs. Longwatch
creates a “video sequence of events recorder.” The operator can switch to a live video feed and
monitor the process from the control room.

If more data is needed for a detailed analysis of the problem, all or part of the Longwatch system’s
video history can be retrieved from the Longwatch Video Engine in high-resolution format,
downloaded to a thumb drive or DVR, and viewed on a PC.

The Video Historian enables users to acquire and store video clips linked with process and
manufacturing variables such as time of day, camera number, batch step, machine ID and other
control system tags. This gives users the ability to store hourly, daily, or weekly thermographs of
process components to benchmark patterns and changes over time. It also allows thermal video
clips to be stored for each step of a process, to document that steps were completed successfully
or for quality control purposes.

The Video Historian allows multiple images to be displayed at the same time, so engineers can
compare processes side by side. Process managers may find problems they did not know even
existed and would not have found in the past without thermal imaging.

Having the ability to see imperfections in a process is not the only benefit. Thermal imaging also
allows users to see unnecessary usage of equipment, warning signs that equipment is on the way
out, and gives managers plenty of warning of pending problems, allowing them to make informed
decisions on how to proceed in certain situations.
