FLIR 427-9031-07-00 D-313 C 35MM NTSC UP Thermal Security Camera
When perimeter security demands reliable thermal detection in complete darkness, fog, or smoke, the FLIR D-313 C delivers uncooled thermal imaging at 35mm focal length with NTSC analog output. This camera addresses the challenge of detecting human-sized targets at extended ranges where visible light cameras fail, making it suitable for critical infrastructure, industrial perimeters, and facilities requiring 24/7 surveillance regardless of lighting conditions or weather.
Key Features
- 35mm thermal lens provides narrow field of view for long-range detection and identification
- NTSC analog video output integrates with existing analog infrastructure and legacy DVR systems
- Uncooled thermal sensor requires no cooldown time—operational immediately on power-up
- Thermal imaging penetrates darkness, light fog, smoke, and dust without supplemental illumination
- Detects heat signatures from humans, vehicles, and equipment based on temperature differential
- Environmentally sealed housing designed for continuous outdoor operation
- Reduces false alarms compared to motion-based visible cameras by detecting actual thermal presence
The D-313 C's 35mm focal length narrows the field of view to concentrate thermal detection on specific zones—fence lines, gates, or building approaches where intrusion is most likely. Unlike visible spectrum cameras that rely on contrast and lighting, thermal imaging detects the infrared radiation emitted by all objects above absolute zero, making concealment nearly impossible. Integration with existing NTSC-based recording and monitoring systems eliminates the need for IP infrastructure upgrades in retrofit scenarios.
Thermal technology excels in scenarios where visible cameras struggle: complete darkness without IR illumination, environmental obscurants like steam or vehicle exhaust, and high-contrast lighting conditions that cause visible cameras to bloom or lose detail. The NTSC output supports direct connection to analog monitors, matrix switches, and coax-based transmission systems common in industrial and government installations. For integrators managing facilities with established analog video infrastructure, the D-313 C delivers thermal capability without requiring network reconfiguration or encoder deployment.
