KBA12 Explosion-Proof IR Mining Camera
Overview
The KBA12 mining-use intrinsically safe camera is suitable for use in environments where there is a risk of explosion due to the presence of methane gas and coal dust; it is designed to function in conjunction with a camera unit in dark conditions.
This product is manufactured in strict compliance with the regulations and standards set forth in GB/T 3836.1-2021, *Explosive atmospheres — Part 1: Equipment — General requirements*, and GB/T 3836.4-2021, *Explosive atmospheres — Part 4: Equipment protection by intrinsic safety “i”*.
Product List
Engineered for high-risk underground coal mines, the KBA127 Explosion-Proof IR Mining Camera features a motorized varifocal lens with an integrated two-way audio intercom. The intrinsically safe and flameproof housing strictly isolates internal circuitry, preventing ignition in volatile methane and coal dust atmospheres.
Features :
304/316 Stainless Steel: Superior durability engineered to withstand heavy impacts and corrosive underground mine water.
Deep Learning AI: Built-in algorithms support personnel counting, anomaly detection, and smart event alerts (e.g., line crossing, loitering).
Scale-Prism IR Illumination: Hidden LED design delivers soft, uniform night vision up to 50 meters in 0 Lux mine shafts.
High Protection: IP67 rated for absolute defense against heavy dust and water ingress in abrasive environments.
Integrated Audio: Dual microphones and a built-in speaker enable real-time communication and audio anomaly detection (steep rise/drop).
Mining-Grade Connectivity: Supports fiber optic transmission (up to 10km) and intrinsically safe power supplies with optional battery backup.
