Industrial Surveillance Fails Where Conditions Are Extreme
In controlled environments, most surveillance systems perform adequately.
But in steel plants and heavy industrial facilities, the challenge is completely different
- High ambient temperatures
- Continuous infrared radiation
- Dust, vibration, and electromagnetic noise
- Need for uninterrupted monitoring
In such conditions, standard cameras don’t just underperform —they fail silently or give
misleading data.
The AMNS Requirement: Reliable Thermal Monitoring, Not Just Visibility
At the AMNS facility, the requirement was not conventional CCTV.
It was:
A precise and constant temperature measurement in a highly irradiated industrial area.
This entailed many potential dangers:
- Warping of images by infrared rays
- Deterioration of sensors with usage
- Decline in temperature measurements’ precision
- Unreliability in constant exposure conditions
The Main Problem
Restrictions of the Industrial Environment
- Strong emission of infrared in adjacent processes
- Highly irradiated environment that may affect sensors’ effectiveness
- The problem of obtaining inaccurate thermal information
- Necessity of operating constantly
Engineering Solution: Shield the System without Blocking the Signal
This did not involve just picking a different camera.
It involved engineering the environment within which the camera operates.
Ex-Proof Case and Germanium Glass Window
Our Solution Entailed:
Ex-proof case
→ To withstand industrial conditions
Germanium glass window
→ Integral in thermal imaging cameras
Significance of Germanium Glass
Unlike ordinary glass:
- Transmits infrared rays effectively
- Does not distort thermal measurements
- Preserves sensor efficiency
- Safeguards internal components from environmental factors
This is more than an attachment – it is the heart of thermal precision
System Architecture: Designed for Stability, Not Convenience
Integration of Field with Control Room
Components Used:
- Thermal camera with USB connectivity
- 4–20 mA signal for integration with the monitoring system
- Six-core screened cable
- Explosion-proof junction box with SMPS power supply
- Fiber optic communication via SFP modules
- Media converters linking to the control room
- Integration with DDC system
Data Communication
- Reliable data transfer over 400 meters distance
This Is What It Achieved
This process was not an installation process; it was establishing a reliable system in a
challenging environment.
Results Obtained
- Temperature readings despite high radiation level
- Component protection
- Safe communication over long distances
- Effective integration into the plant’s monitoring systems
Lessons Learned from Fieldwork
In industrial applications, the key focuses are on:
- Camera brand name
- Camera resolution
- Camera price
But in reality
Environment dictates the system design, not technical specifications
Installation Errors Commonly Made
- Use of general enclosure in extreme heat locations
- Failure to consider the effect of infrared radiation
- Misuse of cables resulting in signal distortion
- Lack of control system integration (DDC/SCADA)
End Product
A system that appears to work – but cannot be relied upon
Final Word
In industrial surveillance:
Precision means security.
Reliability means responsibility.
Failure to deliver either equals danger.
