DELEITE DWY-TS4228T-V3 Dual-Spectrum Thermal & Visible Light PTZ Camera with Precision Temperature Measurement

Overview

The DELEITE DWY-TS4228T-V3 is a dual-spectrum pan-tilt-zoom (PTZ) surveillance camera engineered for mission-critical thermal monitoring and visual verification in industrial, infrastructural, and environmental safety applications. It integrates uncooled vanadium oxide (VOx) microbolometer technology operating in the long-wave infrared (LWIR) band (8–14 µm) with a 4-megapixel visible-light CMOS sensor—enabling simultaneous radiometric temperature measurement and high-fidelity optical imaging under all lighting and atmospheric conditions. Unlike single-spectrum systems, this architecture supports correlated analysis: thermal anomalies are spatially registered with visible details, allowing operators to distinguish between genuine fire events and benign heat sources (e.g., reflected sunlight, machinery exhaust). Its calibrated radiometric engine delivers traceable temperature data compliant with ISO 18434-1 (condition monitoring — thermography) requirements for predictive maintenance and early fire risk assessment.

Key Features

• Radiometric thermal imaging at 256 × 192 resolution with real-time pixel-level temperature mapping across −20 °C to +550 °C
• 4 MP visible-light channel with 32× optical zoom (4.8–153 mm focal length), delivering sub-meter detail recognition at extended ranges
• Integrated 100 m-range infrared illuminator with adaptive intensity control and algorithmic defogging for degraded visibility (e.g., haze, light rain, dust)
• On-device deep learning inference engine trained on multi-class fire and smoke signatures—validated per UL 268 Annex B and EN 54-29 test protocols
• Precision PTZ mechanics featuring 300 programmable presets, 8 customizable scan patterns, and 0.1° angular repeatability for repeatable forensic positioning
• Robust mechanical design: die-cast aluminum housing, IP66-rated ingress protection, and 6 kV line-to-ground surge immunity per IEC 61000-4-5
• Wide-temperature operation from −40 °C to +70 °C, validated per MIL-STD-810H Method 501.7 (low/high temperature) and Method 506.6 (humidity)

Sample Compatibility & Compliance

The DWY-TS4228T-V3 is designed for continuous outdoor deployment in environments subject to electromagnetic interference, thermal cycling, and particulate exposure. Its VOx detector requires no active cooling, eliminating cold-start delays and enhancing long-term stability. The system complies with key international standards including IEC 62471 (photobiological safety—ensuring no retinal hazard from IR illumination), EN 62366-1 (usability engineering for medical-grade interfaces), and GB/T 30148–2013 (Chinese standard for video surveillance system interoperability). Radiometric calibration is NIST-traceable via factory certificate, supporting audit readiness for ISO 9001, ISO 45001, and OSHA 1910.137-compliant electrical safety programs.

Software & Data Management

The camera embeds firmware supporting ONVIF Profile S (streaming) and Profile G (storage), enabling seamless integration into enterprise VMS platforms such as Milestone XProtect, Genetec Security Center, and Avigilon Control Center. Temperature metadata is embedded in MJPEG and H.265 video streams using standardized EXIF and RTSP header extensions. Local 256 GB microSD storage implements wear-leveling and journaling for >50,000 write cycles; offline recording automatically resumes upon network restoration without frame loss. Audit logs—including configuration changes, alarm triggers, and firmware updates—are retained for 180 days and exportable in CSV/JSON format. Optional firmware upgrade path supports future AI model retraining via secure HTTPS-based OTA delivery.

Applications

• Industrial perimeter monitoring: Oil & gas tank farms, chemical storage facilities, and power substations requiring flame detection at ≥250 m and smoke plume tracking over 1.5 km
• Infrastructure asset protection: Tunnel entrances, railway yards, and port container terminals where thermal drift and ambient lighting variability challenge conventional CCTV
• Wildland-urban interface (WUI) surveillance: Early wildfire detection in forested or rural zones, with georeferenced thermal alarms fed into GIS-based emergency dispatch systems
• Logistics and warehousing: Real-time hotspot identification on battery storage racks, conveyor belts, and HVAC ductwork—supporting NFPA 855 and UL 9540A compliance workflows
• Smart city deployments: Integration with municipal IoT platforms for multi-sensor situational awareness during public events, festivals, or disaster response operations

FAQ

Does the DWY-TS4228T-V3 support radiometric video export for third-party thermal analysis software?
Yes—raw temperature data per pixel is encoded in 16-bit TIFF sequences or embedded in H.265 streams via custom metadata tags compatible with FLIR Tools, ThermaCAM Researcher, and MATLAB-based thermal analytics pipelines.
Can the camera be configured to trigger external relays or PLC inputs upon fire detection?
Yes—two programmable dry-contact outputs and one RS-485 port support hardware-level alarm signaling to fire panels, sirens, or suppression systems per EN 54-2 and EN 54-4 standards.
Is firmware update capability available over the network, and does it include rollback functionality?
Yes—HTTPS-based firmware upgrades include SHA-256 signature verification and automatic fallback to the previous stable version if integrity checks fail.
How is thermal calibration maintained over time and temperature fluctuations?
The VOx detector employs non-uniformity correction (NUC) with shutterless adaptive algorithms, performing background calibration every 10 minutes during operation and after significant ambient shifts (>5 °C/min), ensuring sustained accuracy without mechanical shutter wear.
What cybersecurity measures are implemented to protect against unauthorized access or data exfiltration?
The device supports TLS 1.2/1.3 encryption for all management interfaces, IEEE 802.1X port-based authentication, role-based access control (RBAC) with five privilege tiers, and disabled default credentials enforced at first boot per NIST SP 800-160 Vol. 1 guidelines.
