KBA127 Explosion-Proof Fixed Mining Bullet Camera
Overview
Engineered for the rigorous demands of underground coal mining, the KBA127 Explosion-Proof Fixed Bullet Camera delivers 2MP high-definition surveillance with exceptional network flexibility. Housed in a heavy-duty 304 stainless steel enclosure and certified to Ex d I Mb flameproof standards, it provides absolute protection against volatile methane and coal dust. Uniquely equipped with triple SC fiber optic ports and dual Gigabit RJ45 interfaces, alongside native AC127V mining power support, it is the ultimate “install-and-forget” solution for seamless integration into complex underground network rings.
Product List
Advanced Fiber Connectivity : Features 3x SC fiber optic ports (up to 20km transmission) and 2x self-adaptive Gigabit RJ45 ports, ideal for building robust underground network topologies.
Native Mining Power: Directly supports AC127V (75%-110% tolerance) power supply, eliminating the need for external power adapters in mine shafts.
Rugged Flameproof Design: Constructed from highly durable 304 stainless steel, achieving IP68 water/dust proofing and Ex d I Mb certification for absolute safety in Zone 1 mining areas.
2MP Starlight Vision: Captures crisp 1080p video at 25fps, utilizing a 0.005 Lux starlight sensor and 30m high-efficiency IR array for pitch-black tunnels.
Flexible Lens Options: Available in multiple fixed focal lengths (2.8mm, 4mm, 6mm, 8mm, 12mm) to perfectly match your specific field-of-view requirements.
Smart Analytics: Built-in intelligent detection for Line Crossing and Region Intrusion, optimizing safety protocols along conveyor belts and restricted zones
