Explosion Proof Dome Camera Housings

Selecting the correct explosion proof dome camera housing involves more than just matching the physical dimensions. Follow this four-step checklist to ensure you spec the right model for your project:

1. Verify the Hazard Type: Determine exactly what volatile substances are present. Combustible dust (like grain or flour) requires different handling and temperature thresholds than flammable gases (like methane or hydrogen). Check with the facility’s safety engineer to confirm the exact Class, Division, and Group requirements. You can also try our classification finder to easily identify the hazardous area rating required for your explosion-proof cameras.
2. Calculate PTZ and Lens Clearances: Dome housings must accommodate the physical footprint and movement of the camera. If you are installing a PTZ camera, ensure the internal dimensions allow the camera block to fully pan and tilt without striking the glass. If you are using a fixed camera with IR illuminators, the lens must sit completely flush against the bubble to prevent infrared reflection and blinding glare.
3. Determine the Mounting Strategy: Explosion proof domes are significantly heavier than standard security cameras because they are constructed from thick 316L stainless steel or heavy cast aluminum. Evaluate your ceiling height and structural supports to decide whether you need a heavy-duty pendant mount for a high ceiling, a reinforced wall bracket, or a specialized corner adapter.
4. Assess Climate and Condensation Risks: Dome bubbles are particularly susceptible to interior fogging in high-humidity areas or environments with rapid temperature fluctuations. If the camera will be exposed to extreme cold, coastal humidity, or sudden temperature shifts, select a model with an integrated heater and blower system to keep the viewing window completely clear.
