PTZ cameras in quarries

At eight quarries run by the multi-national firm Hanson, Sabre Security Systems has installed Revader Totem PTZ cameras.

Chris Willett, Director of Ellesmere Port based Sabre Security Systems , said: “Quarries are of course potentially very dangerous places to work in and understandably our clients take the safety of their employees, as well as visiting customers and sub-contractors, very seriously. They have therefore never hesitated to invest in the latest technology to ensure their sites comply at all times with very strict health and safety procedures. One of the main concerns however at each of the eight quarries has been the activity that may take place at night or when the sites are closed during holiday periods. There has, for example, been a number of diesel thefts, as well as incidents of youths trespassing just to have some fun, and by doing so they have caused damage and put themselves in harm’s way by attempting to play with dangerous machinery.”

Hanson invited a number of installers to submit proposals to supply and install CCTV which would cover each of the eight quarries. Despite tough competition, Sabre Security Systems were awarded the contract based on their recommendations that Revader Totem PTZ cameras should be specified.

About the Totem PTZ

A re-deployable vandal resistant camera and recording solution with a 36x optical zoom lens it can be remotely controlled to allow operators to observe detail and track the movement of people, machinery or vehicles. When not remotely controlled, the camera can be programmed to move to up to 128 pre-set positions. Its rugged construction makes it suitable the makers say for harsh sites such as quarries, whilst the camera’s day-night function means that it can capture colour images when light levels are as low as 0.07 lux and monochrome images at 0.01 lux. Available with the option of Ethernet, WiFi or 3G connectivity, the Totem PTZ uses the Linux based Wavestore video recording and management software.

Chris Willett said: “Although the Totem PTZ’s are designed to be re-deployable, in this instance they have proved to be a highly cost-effective and robust method of monitoring the quarries compared to traditional CCTV cameras. The obvious additional benefit is that if required they can be quickly and easily removed and installed at another site.” A total of 13 Totem PTZ’s have been installed across the eight Hanson sites in the north west of England and Wales. At night or at other times when the quarries are not operating, external intruder detection sensors trigger the transmission over 3G of live images of any activity to a call centre where an operator can verify what is occurring and, if appropriate, call an authorised ‘key holder’. The recorded video of any incident can be remotely retrieved with the Wavestore software.
