This report outlines an effective surveillance design that covers the premises of a gold storage facility in Australia. The CCTV surveillance system will cover main the inner space of the premises starting from the main gate, parking area, the control room building, workshop building, gold storage building, all the entrances, and the fences surrounding the premise. Based on the high security need in the gold storage facility due to the high value of gold, the design considers an effective surveillance system, which will detect all intrusion, identify people entering the premise, and vehicle number plates. In addition, with the incorporation of internet and programmable systems, the CCTV surveillance system will be able to communicate any risk or theft attempts to the control room, management cell phones, and even the police officer in charge (Barnard. R. L., 1988). On the other hand, cameras have been selected and installed in strategic position effectively depending on the level of risks. The site assessment carried out by the design team enabled the identification of vulnerability and areas of threats. The assessment also gave the team a proper understanding of the gold storage facility major risk problems, which have been addressed by the design fully (Botin. J.A., 2009). Other factors that have been addressed in the design include lighting, cabling, video recording, monitors, and CCTV lines. Site layout The gold storage facility as it is shown in the CCTV system map comprises of six main areas; the gold storage area, workshop, office and reception area, the parking area, main entrances, and the fence surrounding the premise. The parking area is in between the main entrance and the auto sliding gate. The auto sliding gate faces the main gate directly (Cieszynski, J., 2007). Risk management and assessment Based on the risk assessment carried out by the design team, three concerns were realized; the role of CCTV systems, theft, and risks of intrusion. The problem of intrusion in the gold storage facility poses some risks into the premise. The insecurity issues can either be internal or external. The external risks may result from the villages that are around by sneaking in with the mission of robbery (Fennelly, L. J., 2004). At times, the alarm systems may be activated by the false alarms such as vibration or movements of animals around the entrance and along the fence. On the other hand, internal risks are likely to happen when contractors or staff members attempts to steal. As a result of these insecurity problems the gold storage facility needed a highly sophisticated CCTV system to monitor operations within the facility and detect incidences of intrusions by identifying individuals and the number plates of entering vehicles (Damjanovski V., 2005). Types of cameras designed and their functions Based on the level of insecurity risks that are likely to happen into the gold storage premises, the design opted for the digital CCTV systems because they are able to identify the people entering the premises. In a case where strangers enter the premise, the digital CCTV system will alert people in the control room, the security personnel, and the management through their cell phones and alarms. The identification and effective communication process is made possible due to the connection of CCTV to the internet and programs installed in the system. In addition, after entering the vehicle number plates of staff members’ vehicle, the CCTV system will be in a position to identify vehicles and also alert the security personnel in case a strange vehicle gets in. The design further enhanced the performance of the system by selecting digital cameras such as LAN or IP cameras. The digital cameras are suitable for the gold storage facility because they eliminate issues of distance by providing quality images despite the distance (Gustin J. F., 2004). Further, the functions of the digital cameras were improved by selecting the best type of the cable, which facilitates clear pictures in the monitoring system. The security lighting facilitates the effectiveness of the digital camera by providing lighting during the night, rain season, and in some cases of fog or mist. Therefore, the design also considered light selection in the design of CCTV system (Harwood E., 2008). Camera installation The design considered both the indoor and outdoor while designing CCTV in the protected areas of the gold storage premises. Some of the factors considered during the design are FOV width and height, distance, height, lens type, and position of the cameras. Due to different level of risks in the protected areas, different types of digital camera have been designed to carry out various surveillance roles such as identification, recognition, and detection (Jeffrey, L. A., 2004). According to the design, detection cameras will help to detect activities happening in a certain area of interest and the recognition cameras facilitates determination of what exactly happens in the protected area. Finally, the identification cameras will help to identify people will attempt robbery or theft among the staff members (JVSG, 2012). The installed cameras have the capacity to detect intrusion and identify both individuals and vehicles number plates. Further, the locations of these digital cameras will effectively carry out the required surveillance. For the achievement of best image resolutions, the design chose camera based on their sensor elements and their lens differently depending on their locations or level of performance expected. The design also designed the CCTV cameras to be checked and maintained regularly to maintain their effectiveness (Karmis M., 2001). Camera 18 (gold building processing area) This camera was positioned on the ceiling at the epicenter of the room with the field view (FOV) of vertical 100.4 and horizontal 116.0 on a 3.0m height. The lens of cameras was designed to be 2mm fixed. Dome of 3600 and CCD colored camera was selected with an image sensor of 1/2inch and 4:3 ratio. The purpose of the camera is to identify illegal activities in the processing area and the personnel involved to detect and prevent theft of items processed (Kruegle, H., 2007). On the other hand, it provides evidence of the suspect movements by doing the functions of a visible deterrent. Camera 16 (Gold building office) A recognize coupled charged camera with 4:3 ratio and image sensor of 1/3inch was installed in the gold building office. The field of view of 48.4 vertical and 61.9 horizontal with lens of fixed 4mm focal length was designed. The main purpose of the camera is to recognise all the operational activities within the room and record theft incidents (Self, D., 2010). Camera 17 (Gold storage room) Being the high risk area, the digital camera’s lens of fixed 10mm focal length will be used to enhance the intrusion and theft identification (Matchett. A. R., 2003). In addition, the coupled charged camera will have an image sensor of 1/2inch with the ratio of 4:3. The field of view will be 27.0 vertical and 35.5 horizontal with 2.8m height (Verity, B., 2003). The built-in switch has been designed to activate the camera and the IR-motion detector to facilitate detection of any movement in the room. The audible and visual alarm connected to the internet communication system will alert operators in the control room and even the management and security personnel through their cell phones. Camera 13 and 14 (in the corners of workshop building) Using the wide lens, the two cameras will be positioned in the room to direct their focus towards the door. Their positioning will cause overlapping, a factor that will cover their blind spots. The color camera with coupled charged effects will be used because the cameras will be facing the doors. The camera will have an image sensor of 1/3inch with the ration of 4:3. In addition, the field of view of 61.9 vertical and 77.3 horizontal with a 3.5m height will be used. The main purpose of the cameras will be recording, recognising, and monitoring illegal or suspicious activities within the workshop. Camera 15 (workshop office) The camera will be positioned in the corner of the workshop office facing the door to monitor and record the in and out movements. A coupled charged colour camera with the ratio of 4:3 and image sensor of 1/3inch will be used. The lens of 4mm focal length and field of view of 48.4 vertical and 61.9 horizontal with a 3.5m height will be used. These features of the camera will facilitate recording, recognition, and monitoring of illegal activities within the office. Cameras 10, 11, 12 and 19 (on the fence) The four cameras will be positions at the four corners of the fence over a height of 3.0m, to facilitate monitoring both the outer and inner sides of the fence. The inner and outer sides of the fence will both have horizontal field of view of 32.6. Camera 7 will be located at the corner behind the workshop and building. The other three cameras will be positioned in the remaining corners for each camera to monitor each fence effectively. On the other hand the design considered installing the sun visor to avoid creation of dark pictures when the sun shines directly to them. The four cameras that monitors the fences were coupled charged colour cameras that will be able to operate in external environment both day and night. They have an image sensor of 1/2inch and the ration of 4:3. Their designed focal length was fixed 10mm and field of view: vertical 27.0 and horizontal 35.5 with a 3.0m height. The four cameras will help in detecting and monitoring early stages of intrusion to help the response team prepare effectively for the incidence. Camera 1 and 2 (open space between the workshop and gold building) Two coupled charged colour cameras with external PTZ were selected to monitor the open space between the workshop and gold storage building. They should have image sensors of 1/2inch with the ration of 4:3. The field of view: vertical52.0 and horizontal 80.0 with a 3.0m height. The two cameras will overlap in middle to effectively cover all the open space. Being the high risk area, the two digital cameras need to be effective to facilitate the surveillance. Their monitoring of the open space will enable detection and recognition of suspicious activities around that area and with the assistance of installed programs and internet in the CCTV system; they will alert the operator in the control room. Camera 3 (fence door) The external coupled charged colour camera was selected to monitor the fence door near the auto sliding gate. The camera needs to have an image sensor of 1/4inch with the fixed 7mm focal length of the lens. This camera facilitates identification of staff members using the gate. It will be activated when members presents their employment ID to the reader. Camera 4 (reception) The camera will be located in the reception facing the reception entry door to recognise people entering the reception. A coupled charged colour camera with an image sensor of 1/3inch will be suitable. The lens of the cameras will have a fixed focal length of 3mm mounted at a height of 2.7m on the wall. Camera 5 (control room) The design considered it the most risk area because the CCTV system is monitored and controlled from the control room. The camera designed has an image sensor of 1/3inch and focal length of fixed 3mm. The field of view of 77.0 vertical and 61.0 horizontal with a 2.7 height was designed for the camera. The camera will identify and recognise all staff accessing the control room. Camera 6 (office area) Being the low risk area, a coupled charged colour camera of 1/2inch image sensor will effectively monitor and recognise all people entering the office. The field of view of 51.0 vertical and 65.0 horizontal mounted on the height of 2.7m will suitably work for the office. Camera 7 (car parking) External coupled charged colour camera positioned at the strategic point on the roof of reception will facilitate monitoring and detection in the packing zone. A camera of 1/3inch image sensor, fixed 4mm focal length, and FOV of 48.0 vertical and 61.0 horizontal mounted at a height of 3.0m will be used. This camera will monitor and help recognise suspicious activities involving the staff members, contractors, delivery, and visitors when preparing to leave the premise (Standards Australia AS 4806.2, 2006). Camera 9 (main entry) Main entry was considered by the design to be the most important area for enhancing securing, hence effective monitoring and identification of individuals and vehicle numbers plates, and any other risk intrusion. The high technology used in the digital CCTV camera allows identification of registered and unregistered vehicles. Therefore, it will facilitate security by limiting the entry of intruders in to the gold storage facility (Ratcliffe, J., 2006). An external coupled charged colour camera with image sensor of 1/3inch, 4mm lens’ focal length will be used. In addition, field of view of 48.0 vertical and 61.8 horizontal mounted at the height of 2.0 has been recommended. Camera 8 (auto sliding gate) The camera at the auto sliding gate plays the role restricting intruders from entering the gold storage facility. After identify the vehicle or individual, it automatically signals the gate automated gate to be opened. The camera will have the following specification: 1/4inch image sensor, fixed 7mm lens’ focal length, and positioned on top of processing building. Lighting, monitors, cabling, and lines Lighting plays the most important role in the system of CCTV, a factor that was given more consideration during the design. The cameras that effectively operate at dawn and dusk and maximise the daylight were selected for the CCTV design so as to minimise usage of artificial lighting. They only need illumination after dark. During the starlight, moonlight, or complete dark condition, the more advanced or digital camera requires artificial lighting of about 11 lux. However, the digital cameras will require artificial lighting when alarms are activated and in a case where camera are needed in high risk areas. Therefore, the lighting system was integrated effectively to ensure effective capturing of images during the recording. On the other hand, the digital camera selected conformed to the internal lighting installed in the gold storage facility (Kamien, D. G., 2006). The use of digital CCTV system and well-designed lines facilitates digital video recording and production of clear images that can be identified by the security personnel. The cabling work was done using the solid copper cables because the signal of CCTV system is broadband. Finally, the LCD monitors were selected to facilitate the monitoring of 19 cameras in the gold storage facility. Conclusion The CCTV system designed for the gold storage facility is a high technology system integrating internet and programmable systems to facilitate monitoring, recognition, and identification of intruders and staff operation activities. Moreover, the system integrates the new technology, monitors, cabling, lighting, and cameras for it to achieve its purpose. References Barnard. R. L. (1988). Intrusion Detection System.
