Key Features

You get remote zoom and focus control, so you don't need to climb up or de-energize the area just to adjust the field of view – useful for towers, pipe racks, or wide storage yards where fixed lenses won't work. The camera has a 1/2.7" CMOS sensor with 2MP resolution (1920×1080 at 25fps). Built-in IR LEDs give you 50 meters of night vision, working in total darkness. It supports H.265 and H.264 compression, has 3D DNR, BLC, HLC, and defog for tough lighting conditions, and includes smart functions like motion detection and exception alarms. Power options are DC 12V or PoE (802.3af), so installation is flexible.

This motorized varifocal explosion-proof bullet camera works well for high‑risk industrial monitoring. Use it at oil and gas refineries, chemical processing units, gas stations, grain silos, offshore platforms, and fireworks or chemical warehouses. It is good for covering large tank farms where you need to zoom in on gauges, monitoring flare stacks, checking pipeline leaks from a distance, or adjusting views remotely without entering hazardous zones.

FAQ

How is this different from a fixed lens explosion-proof camera?

Fixed lens cameras need you to pick a lens before installation. With this motorized varifocal, you can zoom and focus remotely after it's mounted – no need to take the camera down or re-enter a hazardous area.

Can I adjust the zoom through the network?

Yes. You can control zoom and focus remotely via ONVIF, ISAPI, or the SDK. Works with most VMS and NVRs.

Does it have ATEX/IECEx certification?

Yes. The marking is Ex db IIC T6 Gb / Ex tb IIIC T80°C Db. Covers Zone 1 and Zone 2 gas and dust. Certificates are available.

What is the zoom range?

Typical range is 2.8mm to 12mm (4.3x optical zoom). Let us confirm the exact lens model for your order – we can also customize if needed.

Can I use it outdoors in extreme cold or salt spray?

Yes. Working range is -30°C to 60°C. IP68 and 304/316 stainless steel handle rain, dust, salt spray, and humidity up to 95%. Many customers use these on offshore platforms and coastal refineries.
