When enterprise physical security teams deploy cloud-managed cameras into harsh industrial facilities, they quickly encounter an engineering roadblock: leading enterprise cameras rarely come equipped from the factory with compliance for hazardous locations. Deploying smart video surveillance in hazardous environments requires purpose-built enclosures that protect against ignition risks without degrading optical clarity, connectivity, or sensor capabilities.
This case study examines how 2M Technology partnered with a client requiring a protective explosion-proof enclosure for an enterprise-grade Verkada bullet camera. Mid-project, shifting facility conditions altered the site compliance mandate from combustible dust environments to volatile gas zones. Because 2M Technology builds every custom explosion-proof camera enclosure to the highest standards of safety rather than cutting corners, our solution eliminated redesign costs, prevented weeks of downtime, and future-proofed the client’s hazardous infrastructure.
The Client’s Challenge: Deploying Verkada Cameras in Hazardous Areas
Modern industrial facilities in agribusiness, chemical processing, pharmaceuticals, and manufacturing are increasingly upgrading their legacy video systems to modern cloud-managed platforms like Verkada. These platforms deliver centralized management, cloud archiving, and edge-based analytics. However, off-the-shelf camera hardware is primarily designed for standard commercial and light-industrial environments.
Our client operated a complex industrial facility where environmental airborne hazards were a primary design constraint. They needed to install a Verkada bullet camera model CB62-E to oversee a high-value operational zone. The site safety engineer initially classified this location under Class II, Division 2 standards:
- Class II Locations: Environments where combustible dust presents an ignition hazard.
- Division 2 Conditions: Areas where combustible dust is not typically suspended in explosive concentrations during normal daily operations, but could potentially escape or accumulate due to equipment failure or accidental leaks.
The client approached 2M Technology after discovering that standard commercial security cameras fail to meet OSHA and NEC safety mandates. To satisfy strict safety audits and protect personnel, they contracted 2M Technology to design, test, and fabricate a dedicated custom explosion-proof camera enclosure compatible with the specific dimensions, thermal footprint, and lens field of view of their chosen Verkada bullet camera.
The Complication: Mid-Order Project Specification Changes
Shortly after the order was confirmed and fabrication schedules were set, the client’s project engineering team faced an unexpected challenge. A facility layout audit reclassified the installation area. The camera location was no longer situated in a dust-only environment; it was re-zoned to an area subject to hazardous gases, requiring a Class I, Division 2 classification.
- Class I Locations: Environments where flammable gases, vapors, or liquids are present in sufficient quantities to produce explosive or ignitable mixtures.
- Division 2 Conditions: Areas where flammable gases are not typically present in explosive concentrations during normal daily operations, but could potentially escape or accumulate due to equipment failure or accidental leaks.
Panic set in for the client’s procurement and safety teams. In traditional security equipment procurement, ordering a housing rated only for Class II (combustible dust) means the enclosure cannot legally or safely be installed in a Class I (flammable gas) environment. Dust-ignition-proof housings rely primarily on preventing dust ingress and controlling exterior surface temperature. In contrast, flameproof enclosures for Class I environments must be engineered to withstand and contain an internal gas explosion without venting flames into the surrounding atmosphere.
The client contacted 2M Technology with deep concern that their custom explosion-proof camera enclosure order would need to be canceled, re-engineered from scratch, and subjected to extensive delays and change fees. In mission-critical construction and industrial upgrades, waiting an extra 8 to 12 weeks for a newly compliant enclosure can derail project milestones and delay operational startup.
The 2M Technology Solution: Superior Engineering Prevents Project Delays
When the client reached out with their urgent specification change, our engineering support team had immediate good news: no changes, rebuilds, or reorders were necessary for their custom explosion-proof camera enclosure.
Every custom explosion-proof camera enclosure produced by 2M Technology is built to exceed minimal standards. While the client originally requested ratings for Class II, Division 2, our standardized hazardous engineering platform for this series is compliant with Class I, Division 1 and Class II, Division 1 ratings.
| Evaluation Parameter | Specification | Compliance Details |
|---|---|---|
| Client’s Initial Need | Class II, Division 2 | Combustible dust, Abnormal conditions |
| Revised Site Mandate | Class I, Division 2 | Flammable gas, Abnormal conditions |
| 2M Technology Housing | Class I, Division 1 & Class II, Division 1 | Full gas and dust protection under normal operating conditions |
| Resulting Compliance Margin | Dual Class I & Class II coverage | Upgrades protection from Division 2 (abnormal) to Division 1 (continuous) |
Because our custom explosion-proof camera enclosure natively supports both Class I and Class II classifications, the shift from a dust environment to a gas environment was entirely covered.
Furthermore, because our enclosures carry a Division 1 rating, they deliver significantly higher safety margins than the Division 2 rating the client’s revised specification demanded.
Why Division Ratings Matter: Understanding Division 1 vs. Division 2
When designing a custom explosion-proof camera enclosure, knowing the hazard Class is only half of the equation. You also have to know how often the hazard is actually present, meaning whether it is part of daily operations or only appears during abnormal events. Defining this operational threshold is critical for maintaining compliance with NFPA 70, National Electrical Code (NEC) regulations.
Division 1: Normal Operating Hazards
In a Division 1 area, explosive gases, vapors, or combustible dusts are present or frequently expected under normal operating conditions. Equipment designed for Division 1 must withstand continuous exposure and provide absolute mechanical containment. In Class I, Division 1 spaces, the housing must be flameproof: if a spark inside the camera ignites gas that seeped into the enclosure, the housing must contain the pressure and cool escaping gases along precision-machined flame paths so that exterior atmospheres do not combust.
Division 2: Abnormal Conditions
In a Division 2 area, flammable gases or dusts are handled, processed, or stored, but they are normally confined inside closed containers, tanks, or sealed systems. The hazard is present only under abnormal operating conditions, such as accidental pipeline ruptures, valve failures, or ventilation system breakdowns.
Because the frequency and probability of an explosive atmosphere are significantly higher in Division 1 than in Division 2, Division 1 standards require substantially more robust mechanical protection, heavier-duty casting, and tighter manufacturing tolerances.
By delivering a custom explosion-proof camera enclosure compliant with Division 1 ratings, 2M Technology ensured that the customer’s installation was not merely compliant with the Division 2 requirement; it was built to withstand the most stringent containment requirements in industrial physical security.
The 2M Technology Advantage: Custom Explosion-Proof Camera Enclosure vs. Off-the-Shelf Retail
This custom explosion-proof camera enclosure project demonstrates why industrial operators and system integrators choose 2M Technology over vendors who only provide mass-manufactured, off-the-shelf items.
1. Purpose-Engineered Device Integration
Mass-market enclosures are designed as generic boxes. They often suffer from internal reflection, lens distortion, cable pinching, and inadequate thermal dissipation when accommodating specialized cameras. When building a custom explosion-proof camera enclosure, 2M Technology customizes interior mounting brackets, lens-to-window spacing, and cable glands to match the exact dimensions of the client’s camera. For the Verkada bullet camera in this deployment, our team ensured uncompromised optical clarity, unobstructed infrared illumination, and zero disruption to the camera’s onboard analytics.
2. Built-In Protection That Protects Against Scope Creep
Many manufacturers cut material costs by fabricating custom explosion-proof camera enclosures to the absolute bare minimum rating required by an order. If a customer asks for Class II, Division 2, that is the only rating the housing receives. At 2M Technology, we believe that hazardous infrastructure should be robust and adaptable. Our heavy-duty marine-grade stainless steel castings, precision flame paths, and ruggedized optical glass provide dual Class I and Class II, Division 1 containment by default. When site specifications change, our customers are already protected.
3. Direct Access to Technical and Engineering Experts
When project scopes change, industrial integrators cannot afford to wait through weeks of back-and-forth calls between multiple departments. Our technical team works directly with project managers and site engineers. We evaluate compliance mandates, match the custom explosion-proof camera enclosure to NEC Articles 500 through 505 requirements, and provide direct validation documentation so that site safety officers can approve installations without friction.

Frequently Asked Questions (FAQs)
-
Why can’t commercial cameras like Verkada be installed directly into hazardous locations?
Standard commercial security cameras are not sealed or mechanically engineered to contain electrical sparks, internal heat, or potential component failures. In environments with combustible dust (Class II) or flammable gases (Class I), a standard camera can act as an ignition source. Installing a camera inside a custom explosion-proof camera enclosure prevents hot surface contact and mechanical sparks from escaping into the surrounding hazardous atmosphere, maintaining strict compliance with OSHA and National Electrical Code (NEC) guidelines.
-
What is the operational difference between Division 1 and Division 2 ratings?
The distinction comes down to the frequency of the hazard. In a Division 1 area, the hazard is present or expected under normal, day-to-day operating conditions. In a Division 2 area, the hazard is present only under abnormal operating conditions, such as equipment failure, accidental leaks, or ventilation issues. Because Division 1 covers regular, continuous exposure, it requires significantly heavier containment and tighter manufacturing tolerances than Division 2.
-
How can a custom explosion-proof camera enclosure be compliant with both Class I and Class II environments?
Class I (gases and vapors) and Class II (combustible dusts) require different protective engineering principles. Class I containment requires a flameproof structure that can withstand internal pressure and cool exiting gases along precision flame paths. Class II containment focuses primarily on dust-tight sealing and exterior thermal surface management to prevent dust ignition. 2M Technology engineers custom explosion-proof camera enclosures to satisfy both containment and thermal thresholds simultaneously, providing dual-zone compliance across both gas and dust environments.
-
What happens if our site’s hazardous area classifications change during a project?
Site reclassifications during plant expansions or audits are common. When you partner with 2M Technology, our enclosures are built to dual Class I and Class II, Division 1 standards by default. This baseline compliance gives facility managers and integrators built-in flexibility. If your site requirement shifts between dust and gas zones, or upgrades between Division 2 and Division 1, your enclosure remains fully compliant without requiring costly rebuilds, change orders, or installation delays.
