Explosion-Proof PTZ Cameras

An explosion proof PTZ camera combines full pan-tilt-zoom capability with a certified flameproof (Ex d) enclosure designed for Class I Division 1 and Zone 1 hazardous locations. Unlike fixed explosion-proof cameras, explosion proof PTZ cameras provide remote-controlled directional surveillance across wide areas—enabling a single camera to monitor an entire refinery process unit, tank farm perimeter, or offshore deck area that would otherwise require 6-10 fixed cameras.

What Makes a PTZ Camera “Explosion-Proof”?

A genuine explosion proof PTZ camera is not a standard PTZ placed in a protective housing. The entire assembly—PTZ mechanism, motor drives, imaging circuit, IR illuminators, window, and cable entries—must be contained within an ATEX/IECEx or UL-certified flameproof enclosure. The enclosure must pass:

• Pressure test at 1.5x the maximum internal explosion pressure for the applicable gas group
• Flame path gap and length verification to IEC 60079-1 (flameproof enclosures Ex d)
• Surface temperature measurement under full load to confirm T-class rating
• IP66 or higher ingress protection testing

The result is a camera assembly that may weigh 12-25 kg and require heavy-duty mounting brackets, but that can legally operate in Zone 1 / Division 1 classified locations where ignition risk is real during normal plant operation.

Key Features of Explosion Proof PTZ Cameras

• Optical zoom: Quality explosion proof PTZ cameras deliver 30x to 36x optical zoom, enabling target identification at distances exceeding 300 m. Continuous optical zoom with auto-focus maintains image clarity throughout the zoom range.
• Pan and tilt range: Full 360-degree continuous pan rotation with 90-degree tilt range covers complete spherical surveillance zones. Pan speed of 0.1°/s to 100°/s supports both slow tracking and rapid slewing.
• IR illumination: Integrated long-range IR illuminators in ATEX/IECEx certified arrays provide 100-200 m night vision range without requiring separate classified IR floodlights. Auto-switching between color and IR modes eliminates wash-out at close range.
• Resolution: Modern explosion proof PTZ cameras support 2 MP to 4K resolution with H.265 compression for bandwidth-efficient transmission over classified area network infrastructure.
• Presets and tours: Up to 256 preset positions with auto-tour programming allow scheduled surveillance patterns across multiple critical points within a single camera’s coverage area.
• Wiper and washer: Optionally integrated window wiper and washer systems maintain image clarity in rain, dust, or light hydrocarbon mist environments.

Applications for Explosion Proof PTZ Cameras

Explosion proof PTZ cameras are deployed in high-value monitoring scenarios where a single adjustable viewpoint outperforms multiple fixed cameras:

• Refinery process unit surveillance: A single PTZ camera on a pipe rack can cover an entire process unit, adjusting to operator-defined presets for routine checks and zooming to inspect equipment conditions remotely.
• Tank farm perimeter monitoring: PTZ cameras mounted at tank farm corners provide 360-degree coverage of product storage areas, replacing multiple fixed perimeter cameras in Zone 2 / Division 2 locations.
• Offshore platform deck surveillance: Explosion proof PTZ cameras on offshore oil and gas platforms monitor wellhead areas, crane operations, and vessel approach zones with IR capability for 24/7 maritime surveillance.
• Loading and unloading terminals: Truck and railcar loading areas, jetty hose connections, and loading arms in Division 1 zones benefit from PTZ cameras that operators can aim to monitor connection status.
• Perimeter intrusion detection: Long-range PTZ cameras with IR cover hundreds of meters of fenceline at petrochemical plants, replacing dozens of fixed cameras in a cost-effective perimeter system.

Certifications for Explosion Proof PTZ Cameras

Specify explosion proof PTZ cameras that carry both regional certifications needed for your project:

• ATEX (EU): Category 2G, Ex d IIC T6 Gb or Ex d IIB T6 Gb for Zone 1 gas hazards
• IECEx: Ex d IIC T6 Gb — international recognition for Asia-Pacific, Middle East, and global projects
• UL/cUL: Class I Division 1 Groups C and D (or A through D for hydrogen/IIC gas group) — required for US and Canadian installations

Dual ATEX/IECEx + UL certification from a single camera SKU eliminates procurement complexity for global operators.

Veilux Explosion Proof PTZ Cameras

Veilux explosion-proof PTZ cameras deliver 36x optical zoom, 200 m IR range, and 4K resolution in ATEX/IECEx Zone 1 and UL Class I Division 1 certified enclosures. Our PTZ cameras are designed as direct replacements for legacy PTZ systems in classified areas, with standard NPT conduit entries for North American installations and M-thread entries for ATEX/European projects. For fixed-view coverage across the same site, our explosion-proof dome and bullet cameras complement PTZ coverage with cost-effective fixed surveillance. Add explosion-proof LED lighting to maximize camera performance in low-ambient-light classified areas.
