Long-Range PTZ Cameras

Thermal Imaging Cameras for Security and Industrial Monitoring

Thermal cameras detect heat signatures rather than visible light, making them effective in complete darkness, smoke, fog, and adverse weather where standard IP cameras fail. 2M Technology supplies these systems for perimeter security, critical infrastructure protection, wildfire early warning, industrial process monitoring, and explosion-proof hazardous area installations.

How Thermal Cameras Work

Thermal cameras use uncooled microbolometer sensors to detect long-wave infrared (LWIR) radiation emitted by all objects above absolute zero. The sensor converts thermal energy into a grayscale or false-color image based on temperature differences — a human body standing against a cool background appears clearly even with no ambient light. Unlike near-infrared (NIR) cameras that require IR illuminators, thermal cameras need no external light source at any range.

Thermal Camera Types in This Catalog

• Fixed thermal cameras — stationary perimeter monitoring, fence line detection, and building perimeter coverage
• Thermal PTZ cameras — pan-tilt-zoom thermal units for large-area scanning, oil field perimeter surveillance, and coastline monitoring
• Explosion-proof thermal cameras — ATEX and IECEx certified units for Zone 1/Zone 2 and Class I Division 1/2 hazardous locations
• Bi-spectrum units — combined heat-sensing and visible light in one housing for both detection and color identification
• Temperature screening — elevated skin temperature detection for facility entry screening

Key Specifications

Sensor resolutions range from 160×120 (short-range compact units) to 1280×1024 (long-range perimeter systems). Detection ranges from 50m (small format) to 15km+ (long-range PTZ). Sensitivity (NETD) of 25mK or better on all units. Operating temperature -40°C to +60°C. Most units output H.265 RTSP streams compatible with standard VMS platforms including Genetec, Milestone, and Hikvision iVMS.

Applications

• Critical infrastructure perimeter — utility substations, water treatment plants, data centers, refineries
• Wildfire early warning — forest perimeter monitoring in Texas and the Southwest
• Oil and gas facilities — ATEX-rated heat-detection cameras for refinery perimeter and tank farm monitoring
• Port and maritime security — coastal and waterfront perimeter monitoring in all weather
• Campus and correctional security — fence line intrusion detection without illuminators
