Specialist CCTV.

Specialist CCTV.

If you have a special CCTV requirement, give us a call.

A Pan Tilt Zoom camera is required to cover a fence by day and by night. It needs to be installed in a hazardous location so it will need to meet the ATEX 95 equipment directive.

We had the specialist camera flown in with TNT to meet our schedule. The channel tunnel wasn’t reliable enough at the time. Check out why here:

There was no drilling allowed at the camera location so we had to come up with a bracket and bolt system. These items were 100% stainless steel. And we got our measurements right thankfully.

Fitting this expensive camera over the edge of an external metal stairway about 50 meters in the air was a daunting task. We used harnesses to safeguard the camera while it was being fitted. Our engineers also meet all PPE requirements.

We needed to use the existing infrastructure as running cable would have required extensive ground works. And outside the economic scope of works.

So we had a four-core fiber cable at the camera location, approximately 700 meters from the security/reception, the existing analog ATEX PTZ camera was using 2 of the cores.

We use the spare cores to transmit the new camera images from source to reception. We fit a network point, patch(Cat6 from the camera) to POE+ (15Watt), next we used a patch lead from LAN port of POE injector to a suitable media converter, in this case, (RJ45 to ST).

Next move was to do a fiber patch from the MC (ST) to optical fiber termination point (LC).

We needed to get superb cooperation with the IT team on site to identify two further optical patches which were needed (LC-LC) in data room 1 and (LC-LC) in data room 2. Thanks’ Cash. Thankfully all fiber cables were terminated during their initial installation as is standard workmanship when fitting/terminating optical fiber cables.

We sent our engineers on a fiber splicing course in Dublin, especially for this job, with Woods communications in case I needed that expertise.

That’s a Fusion splicer below.

In the data room closest to the security/reception area we needed an optical fiber patch cable (LC-ST) from the cable termination point (LC) to the media converter (ST), next a patch(Cat6) from media converter to the network distribution panel, connecting into a point (traced this point earlier) which was labelled, spare, this was the network point in the security/reception area, our viewing point. If there had not been a spare in place we simply would have run a new cable the short distance and fitted a point.

So now, one more patch (Cat6) required from the wall network point to the client machine, in this case, a Lenovo E73 desktop. The image is viewed on a 4K monitor connected to the client machine using a short HDMI cable.

At the moment we are on a totally isolated network.

The camera software Video Management System is fired up.

The camera discovery tool is clicked. The camera is discovered with relief, and a super picture is now viewable to all. I know you want to see the image, sorry its confidential.

All Atex and ExD documents were handed over to the client on completion.

In the end, all came together.

We would like to thank all who helped and co-operated during this installation
