Axis 02535-001 Q1961-XTE Explosion-Protected Thermal Camera
The Axis 02535-001 (often searched as 02535 001) is a specialized thermal IP camera engineered for continuous monitoring in hazardous and explosive atmospheres where conventional visible-spectrum cameras cannot legally or safely operate. Built to ATEX/IECEx/cULus standards for Zone 2 and Division 2 locations, this device delivers certified thermal surveillance in petrochemical facilities, refineries, chemical storage, grain handling operations, and mining sites—eliminating compliance friction that typically delays hazardous-area deployments. Its Axis IP camera design incorporates an uncooled microbolometer thermal sensor paired with PoE power delivery, meaning you avoid the cost and complexity of running separate power infrastructure into classified zones.
Key Features
- Uncooled Microbolometer Thermal Sensor (384×288 to 768×576 resolution): No cooling maintenance required—unlike cooled sensors that need periodic servicing, this design cuts operational overhead while delivering continuous 24/7 monitoring without seasonal downtime.
- 40 mK Thermal Sensitivity @ 25°C with F1.0 Lens: This means the camera can detect temperature differences as small as 0.04 degrees Celsius. In industrial predictive maintenance workflows, that translates to early warning of bearing wear, electrical hotspots, or insulation degradation before equipment fails—often days or weeks before catastrophic breakdown.
- 7mm Focal Length (55° Horizontal / 40.7° Vertical Field of View): A moderate-angle lens suitable for mid-range monitoring of machinery, tank farms, or equipment clusters typical in refineries and chemical plants. Closer than wide-angle, more focused than telephoto.
- Dual Frame Rate (30 fps or 8.3 fps): Deploy at full 30 fps when active thermal transients demand real-time capture; switch to 8.3 fps over bandwidth-constrained or long-distance networks without sacrificing thermal sensitivity or event logging. Both rates process at full 384×288 thermal resolution.
- H.264 Compression with Zipstream Technology: Reduces bitrate 40–50% compared to standard H.264, meaning you can record weeks or months of thermal footage on modest storage without overprovisioning your NVR or cloud archive.
- Power over Ethernet (PoE Class 3): Draws under 13W via standard 802.3af PoE—no separate power conduit, no additional power supply, no compliance headaches when running cable into a Zone 2 area. One RJ-45 connector handles both data and power.
- IP66 Weatherproof Rating: Direct rain and dust exposure won't compromise operation, critical for outdoor equipment stacks or rooftop monitoring in harsh chemical or corrosive environments. (Does not provide full submersion protection; skip if underwater deployment is required.)
- Operating Temperature Range -30°C to 60°C: Maintains thermal accuracy across ambient swings from arctic winter to desert heat without recalibration, ensuring consistent anomaly detection year-round.
- Axis Edge Vault Hardware-Based Cybersecurity: Signed firmware boot and hardware-backed credential storage protect against tampering and unauthorized access—essential in critical infrastructure where a compromised camera can become a pivot point for facility-wide breaches.
- 1 Alarm Input / 1 Alarm Output: Integrate with existing safety systems, PLC logic, or audible alarms—trigger external devices on high-temperature events without requiring a separate control interface.
- Active Tampering Detection: Alerts operators to lens obstruction, physical interference, or relocation attempts—important in unattended hazardous zones where manual inspection is infrequent or dangerous.
Integration & Compatibility
The 02535-001 outputs ONVIF-compliant video streams, making it compatible with major video management platforms and network video recorders that support thermal ONVIF feeds. Audio input is supported for integration with area annunciators or ambient sound analysis. Dual frame rate flexibility and Zipstream compression reduce demands on PoE switches and storage systems, so you can deploy multiple thermal cameras on existing infrastructure without forklift-upgrade risk.
Thermal Monitoring for Predictive Maintenance
In petrochemical and refinery operations, thermal anomalies often precede mechanical failure by days or weeks. The Q1961-XTE's 40 mK sensitivity enables detection of bearing temperature rise, electrical connector hotspots, or exchanger fouling long before equipment shutdown becomes necessary. This shifts maintenance from reactive (emergency repair, unplanned downtime) to predictive (scheduled service, zero safety risk), a cost differential that typically justifies the investment in ATEX-certified thermal equipment within 12–18 months of deployment.
When to Choose a Different Model
If your facility does not require ATEX/IECEx/cULus certification—i.e., if the site is classified as non-hazardous—consider a standard Axis thermal camera without explosion-protection housing; you'll save 20–30% on acquisition cost. If you need higher thermal resolution for detailed equipment analysis (e.g., circuit-board-level fault detection), evaluate higher-resolution variants within the Axis thermal product family. For applications requiring visual identification alongside thermal data, a dual-sensor (thermal + RGB visible) camera may be more practical, though it adds cost and complexity.
Frequently Asked Questions
Q: Is the Axis 02535-001 truly certified for Zone 2 / Division 2 hazardous areas?
A: Yes. The Q1961-XTE holds ATEX, IECEx, and cULus certifications for Zone 2 and Division 2 classified locations. You must verify that your specific facility's area classification matches these designations; Zone 1 or Division 1 areas require different (typically more restrictive) equipment.
Q: What's the maximum thermal imaging range of the 02535-001?
A: Thermal sensitivity and useful range depend on object size and emissivity. The 40 mK sensitivity at 25°C with the F1.0 lens enables detection of subtle temperature variations in nearby equipment (within 5–15 meters for most industrial targets). Refer to the manufacturer's thermal performance data for your specific application scenario.
Q: Can I integrate the Axis 02535-001 with Milestone XProtect or other major VMS platforms?
A: Yes. The camera outputs ONVIF Profile S (core) video streams, supported by all major ONVIF-compatible VMS systems including Milestone, Axis Camera Station, and third-party platforms. Confirm specific thermal codec support with your VMS vendor if using H.264 Zipstream compression.
Q: Does the 02535-001 require cooling maintenance or recalibration?
A: No. The uncooled microbolometer design eliminates active cooling, cryogenic refills, and periodic recalibration cycles—major maintenance burdens associated with older cooled thermal sensors. Deploy and monitor; minimal servicing required beyond occasional lens cleaning.
Q: What's the power consumption of the 02535-001?
A: The camera draws under 13W via PoE Class 3 (802.3af standard), so it fits within the power budget of any modern PoE switch without overload risk, even in multi-camera thermal deployments.
Q: Can the Axis 02535-001 detect temperature changes in real time?
A: Yes. The 40 mK sensitivity and 30 fps dual frame rate capability enable real-time thermal transient detection. The 8.3 fps alternative is available for bandwidth-constrained networks without sacrificing thermal accuracy.

The Axis 02535-001 addresses a critical gap in industrial surveillance—the intersection of thermal monitoring and hazardous-area compliance. Most thermal cameras lack ATEX/IECEx certification; most explosion-protected cameras lack thermal capability. The Q1961-XTE bridges that gap, eliminating the need for expensive dual-camera deployments or workarounds that delay implementation.
Technical Highlights:
- 40 mK Thermal Sensitivity: For an uncooled microbolometer, this is exceptional. Most uncooled sensors top out around 50–80 mK; the 02535-001's F1.0 lens and optimized electronics push that boundary lower, enabling early-warning detection of anomalies in bearing temperature, electrical resistance, or fluid circulation that precede failure by days.
- Uncooled Architecture: Zero cryogenic maintenance, zero seasonal recalibration, zero risk of coolant leaks. Deploy in remote or difficult-access locations (rooftops, tank farms, outdoor machinery) without commissioning a maintenance crew.
- Dual Frame Rate + Zipstream: 30 fps for fast transients; 8.3 fps for bandwidth efficiency. Zipstream cuts bitrate 40–50%, letting you archive weeks of thermal video on modest storage—critical when your facility runs 24/7/365 and compliance mandates 90–180 days of retention.
- PoE Class 3 Power: Under 13W means the 02535-001 won't dominate a single PoE switch port, so you can deploy 4–8 thermal cameras on a single 60W PoE switch without costly upgrades.
Deployment Considerations:
- ATEX/IECEx certification requires careful area classification verification; Zone 1 or Division 1 sites need different (more restrictive) equipment. Confirm with your facility's safety engineer before purchase.
- Thermal imaging quality depends on object emissivity and ambient conditions. Reflective surfaces (polished metal, mirrors) can degrade target detection; plan lens positioning and background to maximize emissivity contrast.
- The 7mm/55° FOV is moderate—suitable for equipment clusters within 15–20 meters. For larger perimeter or storage-tank monitoring, evaluate a wider-angle thermal variant or accept reduced sensitivity at distance.
Best suited for refineries, petrochemical plants, and chemical processing sites where predictive maintenance on rotating equipment, heat exchangers, and electrical systems justifies the investment in certified thermal infrastructure. ROI typically materializes within 12–18 months via avoided unplanned downtime.
