FLIR 427-0052-01-00 SR-625 Analog Fixed Camera Thermal 25MM

Perimeter security in total darkness, smoke, or adverse weather demands thermal imaging that doesn't rely on visible light. The FLIR SR-625 delivers uncooled thermal detection with a 25mm fixed lens, providing mid-range surveillance where intrusion detection and asset protection require 24/7 visibility regardless of lighting conditions. Analog output integrates into existing CCTV infrastructure without IP network overhead, making it practical for facilities upgrading perimeter security without replacing entire recording systems.

Key Features

• Uncooled thermal imaging sensor detects heat signatures in complete darkness and low-visibility conditions
• 25mm fixed lens balances field of view with detection range for facility perimeters and critical zones
• Analog video output connects directly to existing DVRs and monitoring systems via standard coax cabling
• Fixed mount housing simplifies aiming and installation on poles, walls, and existing camera brackets
• No visible light or IR illumination required — maintains covert surveillance without light pollution
• Thermal detection cuts through fog, smoke, light rain, and complete darkness where conventional cameras fail
• Detects human-sized targets based on body heat rather than visual appearance or clothing
• Rugged enclosure designed for continuous outdoor operation in industrial and critical infrastructure environments

Deploy the SR-625 where conventional cameras lose effectiveness after sunset or in obscured visibility. Warehouses, utility substations, and manufacturing perimeters gain thermal surveillance without the cost and complexity of transitioning to IP infrastructure. The 25mm lens provides a narrower field than wide-angle models, concentrating detection range on specific zones like gates, loading docks, or high-value equipment areas where intrusion detection is paramount.

Thermal imaging eliminates the variables that plague visible-light cameras — shadows from security lighting, headlight glare, camouflage clothing, and seasonal foliage changes. Human body heat creates consistent contrast against background temperatures, reducing false alarms from lighting changes or moving shadows. Integrate with existing analog recording systems and motion detection workflows without learning curves or network configuration, making thermal perimeter security accessible for facilities that aren't ready for full IP migration.
