Hanwha TNO-L4050T Overview
The Hanwha TNO-L4050T is a VGA-resolution thermal bullet camera designed for outdoor surveillance in demanding environments where conventional video analytics fall short. Built on an uncooled micro bolometer imaging device, this fixed-lens thermal system delivers persistent detection day and night—independent of ambient light—making it ideal for perimeter security, critical infrastructure monitoring, and thermal anomaly detection. The TNO-L4050T combines robust weatherproofing (IP66, IK10 vandal rating) with advanced analytics and flexible power options, delivering enterprise-grade thermal imaging in a compact bullet form factor.
Hanwha TNO-L4050T Key Features
- Uncooled Thermal Imaging – Micro bolometer sensor eliminates the need for active cooling, reducing maintenance overhead and enabling reliable 24/7 operation across -40°C to +60°C environments without performance degradation.
- 640x480 VGA Resolution with Multiple Output Formats – Captures thermal video at 640x480, 640x360, and 320x240 resolution options; supports simultaneous composite video output (720x480/576) and USB output (1280x720) for installation and diagnostics.
- 35mm Fixed Focal Length with 17.2° Horizontal FOV – F1.0 aperture lens provides a 17.2° horizontal, 13° vertical, and 22° diagonal field of view, optimized for long-range perimeter detection with a 36-meter minimum object distance.
- Triple Codec Compression with WiseStream II – Supports H.265, H.264, and MJPEG codecs with intelligent bitrate optimization via WiseStream II technology, reducing storage and bandwidth requirements while maintaining thermal fidelity at 8 fps maximum frame rate across all resolutions.
- Advanced Video Analytics and Sound Classification – Integrated motion detection (8 zones, 8-point polygonal), directional detection, appear/disappear, enter/exit, loitering, tampering, virtual line crossing, audio detection, temperature detection, sound classification, and shock detection enable intelligent automation and event-driven alerting without external analytics servers.
- Built-in Gyro-Based Digital Image Stabilization (DIS) – Compensates for camera vibration and movement, critical for pole-mount and outdoor installations subject to wind or vibration.
- Onboard Storage with Micro SD Support – 1-slot SD/SDHC/SDxC card slot supports up to 256GB of local recording, enabling continuous or event-triggered storage independent of network connectivity.
- IP66 and IK10 Vandal-Resistant Design – Aluminum construction with integrated back box rated IP66 (dust and water jet ingress protection) and IK10 (impact resistant to 20 joules), meeting NEMA 4X enclosure standards for outdoor harsh-weather deployment.
- Flexible Power Options – PoE (IEEE 802.3af, Class 3; max 10W typical 8.6W), 12VDC (max 9W, typical 7.5W), or 24VAC (max 10.5W, typical 8.9W) ensure compatibility with existing infrastructure and redundant power architectures.
- PTZ Handover and Open Platform – Supports PTZ handover protocol and open platform integration, enabling seamless thermal-to-visible camera handoffs in multi-sensor deployments and third-party VMS/analytics ecosystem compatibility.
- Privacy Masking and Video Rotation – 24 polygonal privacy masking zones with configurable colors (grey, green, red, blue, black, white) and mosaic options; video rotation supports flip, mirror, and hallway view (90°/270°) for flexible mounting orientations.
- Alarm I/O and Analytics Triggering – 1 alarm input and 2 alarm outputs enable relay-based automation; analytics-driven alarm triggers support integration with external devices, strobes, and notification systems.
Hanwha TNO-L4050T Integration and Compatibility
The TNO-L4050T operates as an open-platform ONVIF-compatible network device, supporting standard VMS platforms and third-party analytics integrations. Thermal metadata and analytics events are accessible via network protocol for event-driven recording and intelligent alerting. PoE power eliminates separate DC power runs, simplifying installation in retrofit and new-build deployments. The camera supports USB connectivity for installation diagnostics and firmware updates. Mounting options include standard ball-mount brackets compatible with outdoor pole, wall, and pendant installations. The fixed 35mm lens and thermal imaging characteristics require pre-deployment field validation to confirm detection range and thermal contrast requirements for your specific application (e.g., perimeter intrusion, fire/heat anomaly, equipment monitoring).
