DVL has an enormous amount of previous relevant experience in our areas of expertise. Details of these projects are as follows:

Australian Customs Service

• Supply, install a major CCTV system across Western Australia & Northern Territory as a part of the National Waterfront CCTV system.

• Supply, install a major CCTV system for video, voice and gate control over IP, including a central monitoring room with vdieo wall and desktop control stations.

• Supply, install and commission a major access control system across 2 sites, network linked to control from one central office via front end computer for monitoring and control, currently linking the new School of Arts complex into this system.

• Design, supply install and commission a site wide security and access control system including 41 doors and 18 alarm areas.
  
• Design, supply install and commission 3 separate CCTV systems to monitor and record manufacture & distribution processes.

• Design, supply install and commission security, access control and CCTV for numerous gold mines, including for Otter, Great Central mines, Normandy Poseidon, Paddington Gold, Centaur, Forrestania, Resolute Tanzania and Ashanti Gold.

• Design, supply and install 36 remote camera sites using Adpro video transmission. Camera sites include cameras on poles at heights from 4.5m to 12m. All poles 6m and above are hinged type steel octagonal tapered section poles. Site equipment is housed in weatherproof cubicles. Cameras are all PTZ or PTZ domes with remote switching facilities.Safe working procedures had to be followed as the majority of work was within freeway reserves.A central control station was developed to provide remote viewing and control via ISDN lines. Fibre Optic cabling and modems have also been used at some remote sites

• Design, supply and install 14 Cameras at Mirrabooka Bus Station, 13 fixed, 1 PTZ Dome. All transmitted to Busport via ISDN leased line using Adpro VST10CA.Morley Bus Station, an existing installation upgraded to transmit to Busport via ISDN leased line using Adpro VST10CA. DVL currently has the comprehensive maintenance contract with the Department of Transport for both Mirrabooka and Morley bus stations.

• Design Supply and install 6 new PTZ cameras and 2 existing PTZ cameras were integrated into a computerised video matrix switcher. All video and control to camera locations was via fibre optic cables to alleviate interference from high voltage/current cables.

• Design, supply and install security system to the Admin building and an 8 PTZ camera CCTV system including a computerised video matrix switcher and interfacing to a multiplexer and VCR to allow remote play back.
• Systems have also been supplied and maintained for CBH facilities at Kwinana, Geraldton, Albany and Esperance
• Some of the PTZ cameras on these sites are explosion proof and at several, video and data to cameras is totally via fibre optic transmission.

• Design, supply and commission 15 PTZ cameras on 5 stacker/reclaimer machines, controlled by a computerised video matrix switcher.
• All video and camera control was multiplexed onto fibre optic, which was routed through a rotary optical coupler.

• Design, supply and commission 9 PTZ cameras on the rail car dumper plant controlled by a computerised video matrix switcher. A high-level control interface from the computerised video to the control PLC for integrated control of cameras and alarm handling.

• Upgrade the CCTV cameras and Control System and twisted pair Video Transmission System.

• Design, supply and commission 30 PTZ cameras on 5 stacker/reclaimer machines, controlled by a computerised video matrix switcher.
• All video and camera control was multiplexed onto fibre optic, which was routed through a rotary coupler.

• Design, supply and commission 10 PTZ cameras and video matrix switcher to plant areas.

• Design, supply and commission 12 PTZ cameras and video matrix switcher to plant areas.
• All video run on telephone twisted pair using launch amplifiers and video line correctors. A special following switcher was designed and installed at underground levels to send required camera over twisted pair.

• Design, supply and commission 15 PTZ cameras and video matrix switcher to plant areas.
