Explosion-Proof 4 MP Bullet Camera

The China Bks BL-EX340NI-I8 is a fixed bullet network camera rated for explosive atmospheres. It delivers a 2560 × 1440 image at 30 fps through a 4 mm lens and uses H.265+ compression across three simultaneous streams. ONVIF support allows integration with standard video management systems.

Hazardous-Area Installations

This unit suits sites such as oil refineries, chemical plants or grain facilities where certified explosion-proof housing is mandatory. The 120 dB wide dynamic range and 0.01 lux colour sensitivity handle high-contrast and low-light scenes. Buyers needing varifocal zoom, pan-tilt movement or a wider horizontal field of view than 83° should consider other form factors.

4 mm Fixed Lens Coverage

The 4 mm lens provides an 83° horizontal field of view, 45° vertical and 99° diagonal at F1.6. That angle determines how much of a process area or perimeter a single camera can monitor. Verify the required coverage distance before ordering, because the lens is not interchangeable.

Questions about this item

What size mounting hole does the M12 lens mount on this camera require?

The lens uses an M12 mount, so the mounting surface needs a matching M12 threaded opening for the lens barrel to seat correctly.

How is the camera oriented after the bracket is fixed, and what step is often missed?

Loosen the bracket screws, set pan 0 to 360 degrees and tilt 0 to 90 degrees, then rotate 0 to 360 degrees for level horizon before tightening all three axes.

Which user-replaceable part will need attention first in a dusty industrial site?

The IR-cut filter mechanism and the front glass window collect dust; plan to clean the window monthly and verify the filter switches cleanly at each service.
