Dome Cameras for Hazardous Locations

The Spectrum D-Series is a range of Explosion-Proof Dome cameras designed and manufactured in Houston, Texas, USA for use in hazardous areas. The D-Series is available as PTZ, Panoramic and Fisheye versions all engineered for process monitoring, security, and safety applications in industries such as oil and gas, chemical processing, offshore platforms, and mining.

D-Series cameras carry a full suite of global hazardous area certifications: cFMus (North America), ATEX (Europe), IECEx (International), INMETRO (Brazil), PESO (India), and UKCA (United Kingdom). Certification numbers include IECEx FMG 18.0020X, FM18ATEX0057X, FM17US0156X, NCC 20.0083X, and FM18CA0103X. This multi-certification coverage allows D-Series cameras to be deployed in hazardous locations worldwide without the need for additional local approvals in most markets.

D-Series Explosion-Proof cameras are certified for the following hazardous area classifications: Class I, II, and III, Division 1, Groups B, C, D, E, F, and G (NEC/CEC North American system); Zone 1 and Zone 21 under the IEC system, covering gas group IIB+H2 and dust group IIIC. This means D-Series cameras are suitable for environments with flammable gases including hydrogen, flammable vapors, combustible dusts, and ignitable fibers, covering the most demanding hazardous locations found in refineries, petrochemical plants, grain handling facilities, and offshore installations.

D-Series Explosion-Proof Dome cameras operate in ambient temperatures ranging from -4°F to +131°F, (-20°C to +55°C). This temperature range covers the majority of industrial outdoor and indoor hazardous area environments, including offshore platforms in cold climates and chemical plants in hot regions. The enclosure’s robust marine-grade construction maintains a reliable seal throughout this range, preventing condensation ingress through the integrated Ex-Breather Drain.

D-Series cameras are available in two enclosure materials: A red, powder coated, Marine-Grade Aluminum (designated with ‘A’), weighing 17–37 lbs (7.7- 16.7 kgs) depending on configuration, and 316L Stainless Steel (designated with ‘S’), weighing 50–63 lbs (22.7-28.6 kgs). The aluminum option provides a lightweight solution for installations where weight is a constraint, such as offshore topsides. The 316L Stainless Steel option offers superior corrosion resistance for highly aggressive environments, including marine, coastal, and chemical processing locations. Both materials are engineered to withstand the physical and chemical demands of Division 1 and Zone 1 hazardous areas.

The D-Series lineup covers three camera form factors.

• The Panoramic series includes multi-sensor dome cameras such as the D101-X-P3827-BD (7MP, 180° coverage), D101-X-P3818-BD (13MP, 180° coverage), and D101-X-Q3819-BD (14MP with remote pan/tilt/roll motors).

• The Fisheye series features the D101-X-M4328-BD, a 12MP 360° Panoramic camera.

• The PTZ series includes the D201-X-Q6075-BD (1080p, 40x optical zoom), D201-X-Q6078-BD (4K UHD, 20x optical zoom), and D401-X- P5655-BD (1080p, 32x optical zoom).

D-Series cameras integrate object and smart analytics for intelligent video analysis including object detection and motion tracking. Cybersecurity provides a hardware-secured cryptographic computing platform to protect device identity, signed firmware and secure boot processes. These features are critical for industrial facilities that must comply with cybersecurity frameworks such as IEC 62443 and NIST guidelines for operational technology networks.

D-Series cameras are compatible with a comprehensive range of certified mounting accessories. Options include the SD-WM Fixed Wall Mount, SD- WM-ADJ Adjustable Wall Mount, SD-DDM Drop Down Mount (with 1.5″ NPT female thread for ceiling/pedestal installations), SD-UM-SS-D1XX Universal Mount with Sunshield, SCS-CM Corner Mount, SCS-PM Pole Mount (fits 2″– 8″ diameter poles), SCS-PM-XL Pole Mount XL (fits 2.25″ –14″ poles), SCS-MM Multi-Mount (supports up to 4 cameras), and SCS-UM Universal Mount. All mounts are manufactured from electropolished 316L Stainless Steel for corrosion resistance. A SCS-VM Vibration Mount is also available for installations subject to mechanical vibration.

Every D-Series camera ships with the SD-RSK Reliable Securing Kit, which is designed to comply with the DROPS (Dropped Object Prevention Scheme) standard for offshore and elevated installations. The kit includes vibration- ready bolted connection hardware, a secondary retention cable to prevent the camera from falling if the primary mount is compromised, and a galvanic corrosion prevention gasket set to protect against electrochemical corrosion at the junction between dissimilar metals, a common concern in marine and coastal environments.

Yes. All D-Series Explosion-Proof Dome cameras include an integrated Ex-Breather Drain (also referred to as an Explosion-Proof Breather Drain). This device allows pressure equalization between the inside of the enclosure and the external atmosphere while preventing liquid water and contaminants from entering. Pressure differentials caused by temperature cycling, common in outdoor industrial environments, can otherwise force moisture into sealed enclosures over time. The Ex-Breather Drain is hazardous area certified and does not compromise the explosion proof integrity of the camera assembly.

All D-Series Explosion Proof Dome cameras are backed by a 5-year manufacturer’s warranty from Spectrum Camera Solutions. This warranty, when registered online, reflects the high manufacturing quality and durability standards applied throughout production at Spectrum’s Houston, Texas facility, which operates under ISO 9001 (quality management) and ISO 14001 (environmental management) certification. The 5-year warranty period is significantly longer than typical industrial camera warranties and provides assurance for long-term capital equipment deployments in hazardous area installations.

The D101-X-M4328-BD Fisheye 360° Dome camera is explicitly listed as NDAA-compliant. NDAA compliance (National Defense Authorization Act, Section 889) prohibits the use of video surveillance equipment from certain restricted manufacturers in U.S. federal government projects and supply chains. For customers in U.S. government, defense, or critical infrastructure sectors requiring NDAA-compliant explosion proof cameras, this model provides a certified solution. For specific NDAA compliance requirements on other D-Series models, contact Spectrum Camera Solutions directly.

D-Series Explosion-Proof Dome cameras are proudly designed and manufactured in the United States by Spectrum Camera Solutions, headquartered in Houston, Texas. USA manufacturing ensures full traceability of materials and production processes, supports NDAA compliance requirements, and reflects Spectrum’s commitment to quality under their ISO 9001 and ISO 14001 certifications. US-origin manufacturing also simplifies procurement for customers with domestic content requirements in federal, defense, or energy sector contracts.

The D-Series camera system is protected by two United States patents: US Patent 9917428, which covers the functional design of the explosion proof camera assembly, and US Patent D858611, which protects the ornamental design of the product. These patents reflect Spectrum Camera Solutions’ ongoing investment in research and development and differentiate D-Series products from non-patented alternatives in the hazardous area camera market.

The D-Series Explosion-Proof Dome cameras manufactured in Marine-Grade Aluminum are supplied with a red, powder coated finish for multiple reasons.
•⁠ ⁠To enhance the resistance to the environmental conditions in which the camera is installed.
•⁠ ⁠To assist with ease of camera location when installed, either in poor light conditions, for a maintenance requirement, or in an emergency situation.
