For many years, closed circuit television systems have been in used in the monitoring of production process within the industrial and commercial sectors. In today’s environment of increased health and safety, it has become much more widely spread in quarries and other companies that operate within the aggregates industry.
The modern CCTV cameras that we now install are small and extremely rugged, producing images that are every bit as clear as the television within the home.
As all quarries vary in size and each have different requirements, there is no “one system” that suits all.
For smaller operations, the CCTV systems are usually cabled together as most of the areas in need of monitoring are located within a few meters from each other (such as a weigh bridge and the designated area for registration plate logging).
On larger sites, both fibre optic and radio transmission can be used to cover large distances across the entire site.
Some sites opt for a large number of static (fixed) cameras covering all the main transfer points, screens, crushers, loading areas etc. Other sites opt for fewer cameras and use pan and tilt dome cameras instead.
There is no limit regarding the number of cameras that can be installed onto a system. We currently serve a number of sites with an excess of sixty cameras (both old and new). So on existing sites where cameras have been pre-fitted for ten years or more, they can be integrated with the new technology.
An important aspect of managing a CCTV network (especially when installed in a quarry) is planned maintenance and servicing. Cleaning the cameras at regular intervals is a must. The quarry dust even manages to creep into the air conditioned control rooms.
On sites where there are more than sixteen cameras, multiple monitors can be installed to create a video wall within the monitoring station.
