CCTV Project for First Great Western Link

Acton Main Line Station 2005:

Secure Vision was asked to design a CCTV, Public Address and Help Point System. This station is a large station with high speed trains running through the station regularly and also on the South side of the station is a large depot for cargo type rolling stock.

Also the ticket office is located on the main road which is above the running tracks. The main control equipment was to be installed in the ticket office compound and our cable routes had to be routed from the communications cabinet to the equipment locations on the platforms.

Access to the platforms is via two large steel stairways.

This station also has high voltage power lines above all of the tracks.

To achieve the fields of view that were required to cover the majority of the platform area, including the passenger help points and stairways, we had no option but to design and install the cameras and PA to be mounted on 5 metre high steel columns.

This was obviously a very large problem because of the over head power lines. We designed the system, that was approved, on the basis that all of the engineering and as importantly, the on going maintenance could be carried out without compromising Health & Safety.

As one would expect, the civil engineering element was going to be very expensive.

Secure Vision carried out the intrusive surveys of available ducting within the platforms and made enquires with the relevant parties to see if alternative / existing routes were available to keep the cost to a minimum.

This cost saving was aided by the use of UTP transmission for both Video and Data. Secure Vision discovered that there were a number of duct routes on the platforms adjacent to the rolling stock depot that could be accessed by channelling through the back wall of the platform, into the existing ducts.

We designed and installed the main containment route down the side of the staircase to the rear of the platform wall, this was routed along the wall in steel conduits, we came through the wall into the existing ducts and then into the new pole / concrete bases that we had installed, which the CCTV columns would be mounted on.

This routing saved many thousands of pounds as we did not have to install ducting into the platforms by digging up and relaying the tarmac and paved surface.

Disruption of the station platforms was kept to a minimum ensuring customer access was unaffected, therefore not affecting the footfall of the station.
