China Bks BL-EX340NI-I5 4MP Explosion-Proof IR Bullet Network Camera 4mm Lens

Explosion-Proof 4MP Bullet Camera

The China Bks BL-EX340NI-I5 is a 4-megapixel explosion-proof IR bullet network camera built for hazardous-area surveillance. Its 1/3" progressive-scan CMOS sensor captures 2560×1440 resolution at up to 30 frames per second. A fixed 4mm F1.6 lens provides an 83° horizontal field of view. Triple-stream H.265+ encoding keeps bandwidth low while delivering 120dB wide dynamic range and 3D digital noise reduction.

Sustained Operation in Hazardous Zones

The explosion-rated housing meets IP68 waterproofing for continuous outdoor exposure. Infrared illumination reaches 50 metres, switching automatically via the IR cut filter for 0 Lux night vision. Shutter speeds from 1/3 second to 1/100,000 second handle variable lighting without motion blur. Three simultaneous video streams support live monitoring, recording and mobile viewing at independent bit rates up to 16Mbps.

Upgrade Path for Legacy Analog Sites

This camera replaces older analogue bullet cameras that lack network integration and high dynamic range. The jump is worth it when sites need 4MP digital clarity, H.265 storage efficiency and certified explosion protection in a single housing. It is not for buyers who require motorised zoom, PTZ movement or thermal imaging capabilities.
