Explosion-Proof 4MP PTZ Dome Camera

The China Bks iBL-EX5425N-AE is a network dome camera built for hazardous-area surveillance. It pairs a 1/2.8" progressive scan CMOS sensor with 25× optical zoom and 16× digital zoom to capture 2560 × 1440 video at 30 fps. The housing meets IP68 waterproofing and explosion-proof requirements for industrial or perimeter security.

IR Night Vision With 120 dB WDR

Infrared illumination reaches 0 lux for monochrome imaging, while colour sensitivity starts at 0.005 lux at F1.6. Wide dynamic range of 120 dB, 3D DNR, defog and electronic image stabilisation preserve detail in high-contrast or adverse weather scenes. Smart defog and regional exposure adapt automatically without external heating or cooling systems.

360° Endless Pan With 256 GB Edge Storage

The pan mechanism rotates 360° continuously at up to 80°/s preset speed; tilt covers -15° to 90° with auto-flip. Two hundred and fifty-six gigabytes of onboard storage accept microSD cards for local recording. Twenty-four programmable privacy masks and configurable pan/tilt speeds from 0.1°/s let installers tailor coverage to site restrictions.

Questions about this item

How do I mount and wire the iBL-EX5425N-AE, and what step is most often missed?

Secure the explosion-proof dome to a rated junction box, run power and network through the sealed cable gland, then tighten the gland to IP68 spec — installers often leave the gland loose, breaking the seal.

Which parts of this 25× optical zoom PTZ will need service or replacement over time?

The pan/tilt motors and IR LEDs are the wear items; the lens assembly is sealed, so only the moving head and illuminators typically require attention after extended use.

What limit appears first when the camera runs continuous 360° patrols at 80°/s preset speed?

Mechanical duty cycle of the pan/tilt drive — sustained high-speed movement generates heat in the explosion-proof housing, so the motor thermal limit is reached before storage or bandwidth constraints.
