After having operated in the field of Hazardous Area equipment and components for over fifteen years, we at Dexter now see that the marketplace has become a lot busier. Other companies, some of them without any specific background in industrial safety, have taken to selling equipment to the same market. 

In the last decade and a half, Dexter has accumulated a great deal of knowledge and expertise about equipment for explosive atmospheres and back in 2005 we started to manufacture Ex cameras ourselves. As an ATEX manufacturer and supplier, it is not only our responsibility to produce cameras that will comply with all applicable regulations, but also to give our clients advice about the safest way to mount, connect and use our cameras. 

Apparently however, this information can be disregarded; on rare occasions, we find that cameras that have been returned to us for service or repair were installed in a careless or sometimes even plainly dangerous way. This can have very serious consequences for the end user; it can cause malfunction of the camera or, more seriously, it may compromise its safety. Using the wrong cable gland - or using it in the wrong way - can make a perfectly safe product unsafe, thus creating a serious danger to the people working in its perimeter.

This is what taking things seriously looks like:

Connecting an Ex device should not be taken lightly as is shown in this installation video by CMP:

All of us at Dexter have had comprehensive training and education in safety matters on a regular basis. We as an ATEX company have a legal obligation to advise our clients about safety in order to get them the best product for their specific needs and circumstances. Our products undergo very extensive testing in order to be certified. For safety’s sake, mounting and connecting these cameras should be done with just as much care and attention to detail.

We at Dexter know that we are seasoned experts in the field of Ex equipment; we know what we are talking about and we stand for quality and reliability. We believe in this approach because we know this will ultimately save lives.

In the spotlight: Ex cameras

Over the past years, we have developed a great deal of knowledge about Ex cameras. 10 years ago we started manufacturing them ourselves, because we wanted to present a truly comprehensive range of durable, high quality cameras, specially designed for the extreme conditions that come with this industry’s territory. It’s not only the cameras themselves that we focus on; we work together with our clients to find out which solutions work best and will fit within their budget. There are several options, for instance, how to integrate a camera into an existing network. IP over Coax or integrating a media converter in a camera for connection with a fibre optic network are examples of such solutions.

In this article, we’d like to present a selection from our camera range: from the simplest surveillance cameras to intelligent infrared cameras. These are the results of our ongoing research and development efforts and we know them to rank among the finest cameras on today’s market. 

DEX20

Dex20foto1DEX20 is an ATEX and IECEx certified compact and lightweight network day/night IR 32X HD 1080p PTZ dome camera that is manufactured completely from stainless steel 316L, for use in potentially explosive atmospheres and harsh offshore and onshore conditions. It delivers superior HD quality motion JPEG and H.264 HD video over IP networks in all light conditions. Fast (450°/second), high precision (0.05°) PTZ control, using a mouse or a joystick, makes tracking objects of interest easy. The Dexcam 20/Q6045 Mk II can capture colour HD video in light conditions down to 0.3 lux, and black & white video in dark conditions as low as 0.03 lux at 30 IRE.
