2.1 Introduction

As a new generation of explosion-proof monitoring device, the Camera adopts advanced
manufacturing technique and new design. It is integrated with clear image, digitization,
intelligence, and easy installation. After installing the Camera, the overall aesthetics of the
monitoring site is not affected.
The Camera is designed and manufactured in strict accordance with standards such as IEC60079-0
EXPLOSIVE ATMOSPHERES Part 0: Equipment General Requirements and IEC60079-1 Explosive
Atmospheres, Part 1: Equipment Protection by Flameproof Enclosures 'd'. The enclosure is rust-proof
and it is rated IP68. The Camera can be widely used in oil, chemical engineering, wharf, port, mine,
aerospace, food processing, and other sites.

2.2 Application

The Camera is suitable for Zone 1 and Zone 2 with explosive gas environment, and Zone 21 and
Zone 22 with explosive dust environment.

2.4 Explosion-Proof Structure

The enclosure will not cause external explosion due to internal electric apparatus operation
●
even if explosive gas mixture enters into the Camera. Several factors have been considered to
guarantee the explosion-proof performance, such as enclosure intensity, junction surface gap
and length among components, and maximum surface temperature of the enclosure.
