The SWGJ Explosion Proof Full-Color Bullet Camera revolutionizes nighttime surveillance in hazardous industries. Unlike traditional cameras that switch to black-and-white in the dark, this advanced series features a state-of-the-art F1.0 super-aperture lens and a high-sensitivity sensor, allowing it to capture vivid color images 24/7, even in ultra-low light conditions (0.0005 Lux).
Encased in a rugged 304 stainless steel housing (with 316 option), it combines laboratory-level imaging with industrial-grade protection. Whether monitoring dimly lit chemical storage yards or offshore platforms at night, this camera ensures no detail—like the color of a vehicle or a warning label—is missed.
24/7 Full-Color Technology (F1.0 Aperture) Equipped with an F1.0 super aperture lens that collects 4x more light than standard cameras. Combined with a supplemental soft light, it delivers bright, colorful video in total darkness, ensuring critical color information is always recorded.
Smart Perimeter Protection Built-in intelligent analytics support Line Crossing (Tripwire) and Intrusion Detection. The camera automatically filters out false alarms and triggers alerts only when a person or vehicle breaches a defined zone.
Robust Explosion-Proof Design Certified with Ex db IIC T6 Gb markings. The anti-corrosion stainless steel body (IP68) withstands explosive gases, dust, and harsh weather, making it ideal for oil refineries, gas stations, and chemical plants.
Flexible Power & Installation Supports PoE (802.3af) for single-cable installation or standard DC 12V. The compact bullet design with an adjustable bracket allows for easy mounting on walls, poles, or ceilings.
