Axis Q1941-E Thermal Outdoor Bullet Camera

Axis Q1941-E Thermal Outdoor Bullet IP Camera

The Axis Q1941-E is a professional-grade thermal imaging camera engineered for outdoor perimeter security, critical infrastructure monitoring, and threat detection in extreme environmental conditions. Unlike conventional cameras that rely on visible light, this thermal camera detects heat signatures, enabling reliable surveillance in total darkness, through smoke, fog, and severe weather—conditions where standard cameras fail.

Key Features

• Thermal imaging with uncooled micro bolometer sensor for heat-based detection
• High thermal sensitivity (NETD <70 mK) for precise object identification at distance
• Thermal resolution up to 768x576 pixels with 384x288 native sensor
• Multiple focal lengths (7–60mm) with customizable fields of view (6.2°–55° horizontal)
• IP66-rated weatherproof housing for harsh outdoor environments
• Operating range: -40°C to +60°C for extreme climates
• PoE (Power over Ethernet) powered—single cable installation
• H.264 compression with Zipstream technology for efficient bandwidth management
• Electronic image stabilization for steady thermal footage despite vibration or movement
• Frame rates up to 30 fps for real-time monitoring and incident capture

Technical Specifications

The Q1941-E delivers advanced thermal performance with an uncooled micro bolometer sensor, eliminating the cooling complexity of legacy thermal cameras while maintaining <70 mK thermal sensitivity—essential for detecting subtle heat variations indicative of intruders or equipment anomalies. The camera supports multiple lens configurations, enabling deployment from wide perimeter coverage (55° FOV) to long-range threat identification (6.2° FOV). H.264 compression combined with Axis Zipstream reduces storage and bandwidth demands without sacrificing thermal image quality.

PoE power delivery simplifies installation by requiring only a single network cable, eliminating separate power supplies and reducing infrastructure costs. The IP66 rating ensures operation in rain, dust, and spray environments. Firmware signing and local storage options enhance security and operational resilience.

Ideal Applications

• Perimeter security for fences, gates, and boundaries
• Critical infrastructure protection (power plants, refineries, utilities)
• Border and coastal surveillance
• Airport and seaport monitoring
• Industrial site protection in harsh weather
• Search and rescue operations

The Q1941-E addresses a critical gap in outdoor surveillance: the inability of standard cameras to perform in low-light, obscured, or adverse-weather conditions. Thermal imaging detects objects by their heat signature rather than reflected light, making it immune to darkness, fog, rain, and smoke—common challenges in perimeter security.

The <70 mK thermal sensitivity specification is particularly significant for outdoor deployments, enabling detection of human-sized objects at distances where conventional cameras are blind. The uncooled micro bolometer sensor eliminates the maintenance burden and cost of cooled thermal systems while delivering professional-grade sensitivity.

Multiple focal length options provide operational flexibility: wide-angle lenses cover large perimeters, while telephoto lenses enable long-range threat identification. The 30 fps capability at certain resolutions ensures smooth motion capture for forensic review, critical in security investigations.

PoE integration streamlines deployment in remote locations where power infrastructure may be limited, while Zipstream compression reduces storage costs—a significant factor for continuous thermal monitoring systems that generate substantial data volumes.
