Thermal Imaging Cameras for Insulation Inspection

For basic insulation surveys in smaller areas or electrical cabinets, entry-level resolutions like 80×60 (FLIR AX8) or 160×120 (TNC20) are sufficient. For larger structures or finer defect detection, mid-range resolutions of 320×240 to 640×480 — such as those found in the FLIR A400, A500, and A700 — provide significantly more detail and enable more accurate thermal profiling across wider fields of view.

Most cameras in this category achieve ±2°C or ±2% of reading (whichever is greater), including all FLIR A-series and Seek G300 models. The Seek G300 specifies ±5°C for its lower temperature range. For insulation inspections, ±2°C accuracy is generally sufficient to detect meaningful heat loss anomalies. Measurement accuracy is typically specified at ambient temperatures between 15°C and 35°C.

Yes. Cameras such as the FLIR A40 Smart Sensor, FLIR A50/A70 Smart Sensor, FLIR AX8, and the TNC series are designed for permanent fixed installation. They support continuous 24/7 temperature monitoring, configurable alarms (via digital I/O, email, MQTT, or RESTful API), and IIoT integration, making them ideal for ongoing insulation integrity surveillance in industrial facilities.

For outdoor installations or environments with dust, moisture, or washdowns, choose cameras rated IP66 or IP67. IP66 protects against powerful water jets; IP67 adds protection against temporary immersion. Products like the FLIR A50/A70 (IP66), FLIR AX8 (IP67), Seek G300 (IP67), and IRSX (IP67) are all suitable for demanding industrial environments without additional protective enclosures.

Yes. Most cameras support widely adopted industrial protocols including Modbus TCP, EtherNet/IP, MQTT, and RESTful API, enabling direct integration with PLCs, HMI/SCADA systems, and cloud IoT platforms. The IRSX Smart Infrared Camera additionally supports Profinet and OPC-UA. MoviTHERM also offers its proprietary iTL Cloud Monitoring Solution for 24/7 browser-accessible thermal surveillance with alarm notifications.

Thermal sensitivity, expressed as NETD (Noise Equivalent Temperature Difference), measures the smallest temperature difference a camera can detect. For insulation inspections where defects may produce subtle temperature variations, a lower NETD value means better detection capability. Cameras in this range achieve NETD values as low as <30 mK (IRSX) to <35 mK (FLIR A40, A50), enabling reliable detection of minor insulation degradation.
