Technical Specifications & System Limits

Explosion Proof Camera (ExPC) maintains the authoritative technical specifications for its explosion-proof camera systems and documented configurations. All specifications reflect verified product limits and are kept consistent with applicable hazardous-area standards and certification scope. Specification and certification governance sits under the ExPC Technical Authority.

What do ExPC technical specifications cover?

ExPC technical specifications define the mechanical, environmental, electrical, and installation limits within which each camera system is certified to operate.

• Mechanical and enclosure design limits
• Environmental operating conditions
• Electrical and system-compatibility boundaries
• Installation-related technical constraints

What protection ratings do ExPC cameras meet as standard?

Every ExPC camera meets a minimum of T6 (temperature class), IP66 (ingress protection), and IK10 (impact resistance) as standard.

T6

Highest temperature class in IEC 60079 / ATEX. Maximum external surface temperature stays at or below 85 C.

IP66

Fully dust-tight and protected against powerful water jets from any direction.

IK10

Highest impact rating in IEC 62262. Withstands a 20-joule impact.

What enclosure materials does ExPC use?

ExPC explosion-proof enclosures are available in marine-grade aluminum and 316L stainless steel.

Aluminum enclosures offer a strong, lighter-weight housing for general hazardous-area installations. 316L stainless steel enclosures are specified for offshore, marine, coastal, and chemically corrosive environments, where maximum corrosion resistance is required. Both material options are engineered to the same hazardous-area protection principles; the choice is driven by the corrosivity of the installation environment.

How are ExPC cameras classified by product family?

ExPC organizes its explosion-proof camera systems into distinct product families by camera type and enclosure series.

• Dome camera systems — explosion-proof PTZ and fixed dome assemblies for wide-area and pan-tilt-zoom coverage.
• Fixed camera systems — explosion-proof fixed and bullet cameras for dependable single-point surveillance.
• TEZP & FEZB series — 316L stainless steel PTZ and fixed bullet cameras built for offshore, marine, and corrosive environments.
• Junction boxes — certified enclosures for cable termination and electrical connections in classified areas.
• Accessories — mounts, poles, cable glands, and securing kits that complete a certified installation.

What environmental and operating limits apply?

ExPC camera systems are engineered for hazardous (classified) areas and carry certification for the specific gas and dust zones documented for each product.

Hazardous-area suitability is expressed through two international frameworks. The exact rating that applies to a given camera is stated on that product's page and on the Certifications page.

Class & Division (North America)

Class I covers flammable gases and vapors; Class II covers combustible dust; Class III covers fibers and flyings. Division 1 means the hazard is present under normal operation; Division 2 means it is present only under abnormal conditions.

Zone (IEC / ATEX)

Gas atmospheres are graded Zone 0, 1, or 2; dust atmospheres are graded Zone 20, 21, or 22, from continuously hazardous down to rarely hazardous.

How does camera and sensor compatibility work?

ExPC explosion-proof enclosures are engineered to house imaging cameras from leading manufacturers, so operators can standardize on a preferred camera platform without losing hazardous-area protection.

Supported camera platforms include systems from manufacturers such as Axis, Pelco, Hanwha, Avigilon, Bosch, and Verkada, across a range of image resolutions. Sensor and resolution options vary by product family and configuration.

What are the limits of these specifications?

ExPC specifications apply only to documented, unmodified product configurations.

• Specifications apply only to documented product configurations.
• Field modifications may affect certified limits and can void certification.
• Final suitability depends on the installation and on site conditions.

How do specifications relate to certifications?

Technical specifications define the system limits and operating boundaries; certification approval confirms where a documented configuration may be installed within those limits.

In short, specifications describe what a system can do; certification confirms where it is approved to do it.
