Industrial Fire Detection Thermal Camera

Thermal Fire Detection — How Temperature-Based Early Warning Outperforms Smoke and Heat Detectors

Traditional fire detection technologies — smoke detectors and point heat detectors — activate when fire products (smoke particles or elevated air temperature at the detector point) reach the detector location. By the time smoke or heat has spread sufficiently to activate these detectors, a fire may already be well-established. Thermal imaging fire detection identifies the rising surface temperature of materials, equipment, or stored goods that is the precursor to combustion — detecting the abnormal heat build-up before smoke or flame is produced. This earlier detection enables faster response: operators can investigate and address the developing hot spot before it ignites, and automated suppression or alarm systems can activate earlier in the fire development timeline, reducing damage and safety risk.

The SAFETIS EV-C’s 19,200 active thermal pixels continuously scan the monitored area at up to 9 scans per second, measuring the surface temperature of everything within the sensor’s field of view. The onboard SMART evaluation system compares every pixel’s temperature against the configured thresholds for its containing ROI at every scan cycle, generating an immediate alarm output if any pixel within an ROI exceeds its threshold — without waiting for a fire management control panel to poll the device, and without requiring communication to an external computer for evaluation

Dense Thermal Sensing and Rapid Detection at 9 Scans per Second

The SAFETIS EV-C excels with its 19,200 active temperature sensors, providing dense environmental coverage and high-resolution thermal detection. This extensive sensor array delivers precise temperature data across the monitored area, enabling fast detection of heat build-ups, hotspots, and potential fire risks before they escalate. Continuous scanning at up to 9 times per second ensures that even subtle temperature changes are detected within fractions of a second of occurrence, making the SAFETIS EV-C ideal for environments where early warning is operationally and commercially critical — chemical storage, electrical switchrooms, production facilities with flammable materials, and warehouses with high-value goods.

Autonomous SMART Evaluation — No External Hardware Required

The integrated SMART evaluation system operates independently, eliminating the need for external computers or additional hardware for core processing and alarm evaluation. This reduces installation complexity and costs, and increases reliability by minimising dependencies on ancillary systems. All alarm evaluations and outputs are determined directly on the device, ensuring rapid and reliable response when thresholds are exceeded — with or without network connectivity to external monitoring systems. For Indian industrial facilities where network reliability may be variable, this standalone evaluation architecture is a meaningful reliability advantage over systems that require continuous network connectivity to a remote server for alarm evaluation.

Customisable Region-of-Interest Alarms with Dual Thresholds

Up to 32 configurable ROIs with independent warning and critical alarm thresholds enable targeted fire safety coverage tailored to diverse industrial layouts. Each ROI can be sized and positioned to match a specific risk area within the sensor’s field of view — a cable tray, a transformer bay, a stack of stored goods, a machinery enclosure — with thresholds set appropriate to the material and risk level of each zone. Each ROI triggers its configured digital or relay output when its threshold is exceeded, enabling independent alarm and suppression responses for different zones within the same camera’s field of view without requiring separate sensors for each zone.

Network Integration via Modbus RTU RS485 and Ethernet

Supports Modbus RTU communication over both RS485 and Ethernet, allowing seamless integration with existing industrial control systems, fire alarm systems, or building automation platforms. Ethernet connectivity also enables remote monitoring and configuration via the built-in webserver or desktop software, offering intuitive control and real-time alarm management from a remote control room or security monitoring centre. For Indian industrial facilities deploying the SAFETIS EV-C within existing fire detection or building management systems, the standard Modbus RTU protocol ensures compatibility with virtually all industrial fire alarm panels and BMS platforms.

Durable Industrial-Ready Aluminium Housing

Designed with a rugged aluminium body for harsh environments, the SAFETIS EV-C withstands demanding deployment conditions — dust, moisture, vibration, and the elevated ambient temperatures common in Indian industrial facilities. Its robust construction and flexible configuration options make it suitable for factory floors, electrical substations, freight hubs, large warehouses, and any facility where continuous reliable fire safety monitoring is essential across multi-year deployment lifecycles without requiring frequent maintenance or replacement.

Applications Across Industries

Industrial Safety and Machinery Monitoring

In industrial facilities, early fire detection is essential to protect valuable assets, equipment, and personnel. The SAFETIS EV-C continuously monitors thermal conditions across critical machinery, production lines, and electrical installations, spotting overheating and abnormal heat changes long before they escalate into fires:

• Machine and production line monitoring: continuous thermal surveillance of rotating machinery, electrical drives, conveyor systems, and production equipment enclosures for overheating that precedes motor failure, insulation breakdown, or friction-induced fire in Indian manufacturing facilities
• Electrical panel and switchroom monitoring: continuous monitoring of electrical distribution boards, MCC panels, and switchrooms where connection resistance, overloading, or insulation faults produce rising surface temperatures well before fire ignition, enabling early warning and corrective maintenance action
• Chemical and flammable materials processing: continuous thermal monitoring of process areas handling flammable solvents, gases, or reactive materials where early detection of heating anomalies is critical to preventing fire or explosion incidents

Energy Sector and Electrical Infrastructure

Power stations, substations, transformers, and electrical distribution systems generate significant heat and are vulnerable to overheating faults that can lead to catastrophic fires:

• Transformer and switchgear monitoring: continuous thermal surveillance of oil-cooled transformers, GIS switchgear, and busbar chambers for overheating that precedes insulation breakdown or oil fire — particularly relevant for India’s power distribution infrastructure where transformer fire incidents have significant grid reliability implications
• Substation and cable tunnel monitoring: fixed thermal fire detection across cable tunnels, substation buildings, and outdoor switchyard equipment bays where conventional smoke detectors are ineffective due to the large volumes and outdoor exposure
• Power plant auxiliary equipment: monitoring of cable trays, motor control centres, and auxiliary electrical equipment in power generation facilities where fire incidents can trigger plant trips with significant generation loss

Warehousing, Logistics, and Storage

Warehouses storing large quantities of goods — especially flammable materials, chemicals, or high-value goods — benefit from high-resolution thermal scanning that provides continuous vigilance without human intervention:

• High-bay warehouse fire detection: continuous thermal monitoring across large warehouse volumes where conventional point detectors provide insufficient coverage density, with ROIs configured for each rack aisle or storage bay — particularly relevant for India’s rapidly expanding e-commerce and cold chain logistics warehousing sector
• Cold storage and refrigerated warehouse monitoring: the −10°C lower temperature range enables reliable monitoring in cold storage facilities where refrigeration compressor overheating, insulation faults, and electrical equipment anomalies can cause fires in low-visibility environments
• Hazardous goods storage: continuous thermal surveillance of chemical storage areas, flammable liquid stores, and battery storage facilities where early thermal anomaly detection enables intervention before ignition

Fire Detection and Building Automation Systems

The SAFETIS EV-C integrates seamlessly with existing fire alarm systems and building management platforms via Modbus RTU protocols and digital/relay outputs:

• Fire alarm panel integration: relay outputs connect directly to fire alarm panel zone inputs, presenting the SAFETIS EV-C thermal detection as an additional detection layer alongside conventional smoke and heat detectors within the existing fire alarm system without requiring a separate fire detection network
• Building management system integration: Modbus RTU integration with BMS platforms enables fire alarm status, zone temperatures, and alarm events to be monitored alongside HVAC, access control, and other building systems from a central building management console
• Fire suppression system interface: direct relay outputs enable automatic activation of fire suppression systems (gaseous, water mist, or sprinkler) when the critical temperature threshold is exceeded in a defined ROI, without requiring human intervention in the emergency response chain

Security and Asset Protection

Thermal monitoring contributes to facility security by detecting thermal anomalies that indicate electrical faults, unauthorised activity, or unsafe conditions:

• Critical infrastructure protection: continuous thermal monitoring of data centres, communications equipment rooms, and critical infrastructure facilities where fire incidents have severe business continuity and national security implications
• Asset protection monitoring: thermal surveillance of high-value asset storage, server rooms, and equipment areas where early detection of electrical or thermal anomalies protects against both fire damage and the secondary damage from fire suppression system activation
• Perimeter and access security supplement: thermal anomaly detection for unauthorised activity creating heat signatures (cutting tools, incendiary devices) in secured areas, complementing video surveillance with thermal detection that operates effectively in smoke, darkness, or poor visibility conditions
