Hanwha TNO-3020T QVGA Thermal Bullet IP Camera

Hanwha TNO-3020T QVGA Thermal Bullet IP Camera

The Hanwha TNO-3020T is a compact thermal imaging bullet camera designed for perimeter security, facility monitoring, and advanced surveillance applications where temperature anomalies and heat signatures provide critical security intelligence. Built on an uncooled micro bolometer sensor with 320x240 QVGA resolution, this camera detects thermal patterns in complete darkness and challenging weather conditions where traditional visible-light cameras fail.

Key Features

• Uncooled micro bolometer thermal sensor with 60mK thermal sensitivity (NETD)
• QVGA resolution (320x240) at 30fps with H.265, H.264, and MJPEG codec support
• Fixed 4.7mm focal length with F1.0 aperture and 50° horizontal field of view
• WiseStream II smart codec technology for optimized bandwidth and storage efficiency
• 8 selectable color palettes including Whitehot, Blackhot, Rainbow, Iron, and custom options
• IP66, NEMA4X, and IK10 rated for extreme outdoor environments (-40°C to +60°C operation)
• Triple power input: PoE (IEEE 802.3af), 24VAC, and 12VDC
• Built-in gyro sensor for digital image stabilization
• Micro SD/SDHC/SDXC card slot supporting up to 256GB local storage

Advanced Analytics & Detection

The TNO-3020T integrates comprehensive video analytics covering directional detection, motion detection, appear/disappear events, enter/exit zones, loitering detection, tampering alerts, virtual line crossing, audio detection, temperature change detection, sound classification, and shock detection. The camera supports up to 8 motion detection zones with polygonal boundaries and 32 privacy masking areas with multiple color and mosaic options. Alarm I/O provides 1 input and 2 outputs for integration with external security systems, with triggers based on analytics events, network disconnects, or alarm inputs.

Audio & Communication

Dual-channel audio with selectable microphone or line-level input (2.5VDC supply) and line-level output enables two-way communication. Audio compression options include G.711 u-law and G.726 (16–40 Kbps) at 8KHz, plus AAC-LC at 48 Kbps. ONVIF Profile S/G/T, SUNAPI HTTP API, and Wisenet open platform support ensure compatibility with third-party VMS and integration platforms. Streaming supports up to 10 simultaneous profiles via unicast (20 users) or multicast with IPv4/IPv6 and enterprise protocols including HTTPS/SSL, 802.1X EAP-TLS authentication, and SNMPv3.

Applications

Ideal for perimeter surveillance, industrial facility monitoring, wildfire detection, power infrastructure inspection, and security applications requiring thermal anomaly detection in darkness or adverse weather. The robust IP66 and IK10 ratings suit rooftop, maritime, and high-impact environments.

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

The TNO-3020T delivers thermal surveillance capability in a compact, cost-effective package. Its uncooled micro bolometer technology eliminates the cooling maintenance and expense of cooled sensors while maintaining 60mK sensitivity—sufficient for detecting people and vehicles at operational distances. The 4.7mm fixed lens and 50° FOV balance coverage breadth with thermal detail; minimum 1m focus distance suits perimeter mounting.

WiseStream II codec optimization and triple power flexibility (PoE, 24VAC, 12VDC) reduce deployment complexity. Native ONVIF and Wisenet API support integrate seamlessly into enterprise VMS ecosystems. The built-in analytics suite—particularly temperature change detection, loitering, and virtual line crossing—enable autonomous threat detection without external processing. Edge storage (256GB SD) and configurable alarm outputs support autonomous event logging and real-time alert workflows. Operating temperature range (-40°C to +60°C) and NEMA4X certification suit challenging outdoor environments where thermal imaging provides irreplaceable security value.
