China Bks BL-EX340NI-I3 4MP Explosion-Proof IR Bullet Network Camera 4mm

4MP Explosion-Proof Bullet Camera

This IP bullet camera delivers four-megapixel resolution at up to 30 frames per second. It uses a 1/3-inch progressive-scan CMOS sensor and supports H.265+, H.265, H.264+ and H.264 compression with triple streaming. The fixed 4 mm lens provides an 83-degree horizontal field of view. Infrared illumination enables zero-lux night vision. The housing meets IP68 waterproofing and explosion-proof ratings for hazardous environments.

Hazardous-Area Installations Only

The camera suits facilities that require certified explosion-proof equipment such as chemical plants, oil refineries or grain silos. ONVIF compliance allows integration with compatible network video recorders. Power-over-Ethernet simplifies cabling in classified zones. Buyers who need pan-tilt-zoom movement, motorised varifocal lenses or wireless connectivity should look elsewhere.

Fixed 4 mm Lens Determines Coverage

The 4 mm focal length fixes the horizontal field of view at 83 degrees and vertical at 45 degrees. This single optical parameter decides whether the camera covers the required scene width at the intended mounting distance. No zoom or focal-length adjustment is available after installation.
