Hanwha TNM-C3622TDR Bi-Spectrum AI Radiometric Camera

The Hanwha TNM-C3622TDR is a compact dual-sensor bi-spectrum camera engineered for simultaneous visible and thermal monitoring in critical indoor environments. This multi-sensor system combines a 2MP visible channel with an uncooled QVGA thermal sensor to deliver real-time thermal anomaly detection and radiometric temperature measurement across a -20°C to 130°C range. Purpose-built for facility monitoring, equipment condition assessment, and fire prevention in data centers, manufacturing plants, and infrastructure facilities.

Key Features

• Dual-Sensor Bi-Spectrum Monitoring: 2MP visible channel (1920×1080 @ 30fps) with 4mm fixed lens (HFoV: 87.6°) paired with QVGA thermal sensor (320×240 @ 8fps) with 4.7mm thermal lens (HFoV: 50°) for synchronized analysis
• Uncooled Microbolometer Technology: 320×240 thermal resolution with ≤50mK NETD and 12µm pixel size delivers high thermal sensitivity without active cooling for reliable indoor operation
• Extreme WDR Performance: 150dB wide dynamic range on visible channel ensures clear detail in high-contrast lighting without washout or shadow loss
• AI-Powered Detection: Person and vehicle classification on visible channel with detection shot capability for forensic-grade incident verification
• Radiometric Temperature Monitoring: Measure temperature across full field of view or configure up to 6 user-programmable quadrangle ROIs for targeted thermal hotspot detection
• H.265 Compression: Advanced video codec reduces bandwidth and storage requirements while maintaining image quality
• PoE+ Powered: 802.3at PoE+ simplifies installation and eliminates separate power infrastructure

Technical Highlights

The TNM-C3622TDR's multi-sensor architecture enables operators to simultaneously observe visible scene context and thermal anomalies, critical for detecting equipment failures, identifying hot spots in electrical systems, and early fire detection. The 9.1mm fixed lens configuration provides a practical field of view suitable for indoor proximity monitoring. H.265 compression reduces bandwidth consumption while maintaining forensic-quality imagery for incident review. PoE+ power delivery streamlines deployment in existing network infrastructure.

Ideal Applications

• Data center thermal monitoring and equipment hot-spot detection
• Manufacturing facility condition monitoring and predictive maintenance
• Electrical room and utility area surveillance
• Fire prevention and early smoke/thermal anomaly detection
• Critical infrastructure equipment assessment
• Indoor facility management and environmental monitoring

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The TNM-C3622TDR addresses a specific market need: affordable, compact bi-spectrum monitoring for temperature-sensitive indoor environments. The combination of 2MP visible resolution with QVGA thermal allows operators to correlate visible context with thermal signatures in real time—essential for validating thermal alerts and reducing false positives. The ≤50mK NETD specification ensures sensitivity to subtle temperature variations critical in equipment monitoring.

The 150dB visible WDR compensates for mixed lighting conditions common in industrial facilities. PoE+ power eliminates infrastructure barriers to deployment. However, the fixed 9.1mm lens limits adjustability; this camera suits fixed-position monitoring rather than pan-tilt applications.

H.265 compression is standard for modern IP surveillance, reducing operational costs. Best deployed where radiometric accuracy and simultaneous thermal-visible correlation directly impact operational safety or maintenance decisions.
