It had been a particularly slow night. The plant security guard had just made his rounds on this Sunday evening shift. As soon as he passed the weighing scales, he could enter the guard shack and get off his feet. Challenging a curious incident However, on this night, he noticed the waste vendor’s truck sitting half on and half off the scale. He stopped dead in his tracks to see if the truck would back up and completely sit on the scale. It never did. The observant guard walked up to the truck and challenged the driver who seemed surprised. “Hey, you’re not weighing your truck properly.” The driver fumbled for a response before replying, “Sorry, I was on the phone with a friend. I didn’t notice it.” But this security guard had the presence of mind to demand the driver’s phone. The driver was caught off guard and surrendered the phone. The guard then pulled up the most recent incoming/outgoing calls and saw no calls during the last 30 minutes. “I don’t think so.” “You don’t think so what?” The security guard was frank, “You haven’t used this phone in over half an hour.” The truck driver sheepishly acknowledged the fact. It was decided to install CCTV covering the weighing area and scales – no easy feat due to poor lighting Preventing crime as it happens Knowing the driver was lying, the security guard ordered the truck back on the scale for a correct weighing and advised the driver that he would report the incident. The security guard wrote up his report and handed it off to his supervisor who, in turn, contacted the local corporate investigator. This investigator was soon on the phone with his boss at corporate headquarters on the other side of the world. Together with Security, they decided to install CCTV covering the weighing area and scales – no easy feat due to poor lighting. However, once completed, they waited. They would not have to wait long. For the next two months, the waste vendor trucks, filled to the brim with production waste, black-and-white paper and other waste products from the plant, would stop on the scale only for a moment and then drive the front half of the truck off the scale for weighing. It was obvious that the vendor was cheating the company by only paying for half the waste. After two months, it was decided to catch the next cheating driver “en flagrante.” Sure enough, the next truck went half on and half off the scale and was weighed. Security then asked the unsuspecting driver to park his truck and invited him inside the building to talk to a supervisor. The driver signed an incriminating statement about the scheme and his role therein. They sent him on his way asking him to keep it quiet Waiting for the driver in a large office was the local investigator and his close friend, the Head of Security. After a difficult interview, the driver admitted to cheating on the scales over a two-year period—he claimed that some of the scale cheating was done at the direction of the vendor’s management, while some of it he did himself by “ripping off” the vendor—which he acknowledged was dangerous. Working with authorities The driver signed an incriminating statement about the scheme and his role therein. They sent him on his way asking him to keep it quiet—they would see what they could do for him later on. In the meantime, Corporate Investigations had received a due diligence report on the vendor company which contained disturbing news—the company and its managers were associated with a countrywide waste management mafia. The report suggested that the vendor had a reputation for thefts and involvement in numerous lawsuits regarding thefts and embezzlement. Shockingly, no prior due diligence had ever been conducted on the vendor. Fortunately, the plant’s finance and audit team had maintained good records over the past 5 years and were able to re-construct the amount of waste going out the plant door and the amounts being claimed and paid for by the vendor. The discrepancy and loss stood at a multi-million dollar figure. After consulting with the local police authorities and company lawyers, it was decided to pursue a civil case against the vendor. Pursuing legal action The regional lawyer, the Head of Investigations, the Head of Security and the CFO invited the vendor to discuss the problem. Some of the evidence was shown to the vendor’s CEO who became indignant and, in order to save face, promised to fire the truck drivers and to repay any losses for the last two months. Inter-dependent entities - security, investigations, finance/audit and legal - combined their resources and agendas to form a unified front That was not enough for the company and a protracted legal battle ensued which lasted several years and resulted in the vendor’s paying almost the entire amount in instalments. The vendor was dropped from the contract and internal controls strengthened—the only plant employee dealing with the waste issue left the company and was replaced by two individuals. The plant also began paying more attention to the waste process and less to the production side. Several “lessons learned” come to mind. First, the tripwire came in the person of an astute and well-trained security guard who exhibited some of the best characteristics you want to see from men and women in that profession. The Security Department was also adept at installing the CCTV and capturing the fraud live on videotape. But a far greater lesson was learned—of what can happen when inter-dependent entities (security, investigations, finance/audit and legal) within a company combine their resources and agendas to form a unified front. The results speak for themselves.
Critical infrastructure facilities that must secure large areas with extended outer boundary and numerous entry points, present a particularly difficult challenge when it comes to perimeter protection. As such, true end-to-end perimeter protection calls for the utilisation of a sophisticated, multi-layered solution that is capable of defending against anticipated threats. Integrated systems that incorporate thermal imaging, visible cameras, radar and strong command and control software are crucial for covering the various potential areas of attacks. Let’s look at these technologies and the five key functions they enable to achieve an end-to-end solution that provides intrusion detection, assessment and defense for the perimeter. 1. Threat recognition The first step in effectively defending against a threat is recognising that it’s there. By combining state-of-the-art intrusion detection technologies, facilities can arm themselves with a head start against possible intruders. An exceptionally important aspect of effective perimeter protection is the ability to conduct 24-hour surveillance, regardless of weather conditions, environmental settings, or time of day. Visible cameras do not perform as well in low light scenarios and inclement weather conditions. However, thermal imaging cameras can provide constant protection against potential intruders, regardless of visual limitations, light source or many environmental factors. In fact, facilities such as power stations located near bodies of water can use thermal cameras to create what is known as a “thermal virtual fence” in areas where they are unable to utilise the protection of a physical fence or wall. Deterring suspicious activity can be achieved through real-time two-way audio, a simple but powerful tool Critical infrastructure applications require not only continuous video surveillance and monitoring, but also a solution that yields highly reliable intrusion detection, with fewer false alarms. This need makes advanced video analytics a must for any adequate surveillance system. Features like dynamic event detection and simplified data presentation are game changing in supporting accurate intrusion analysis and facilitating a proactive response. Advanced analytics will provide multiple automated alarm notification options, including email, edge image storage, digital outputs or video management software (VMS) alarms. Incorporating high quality, unique and adaptive analytics can virtually eliminate false alarms, allowing security personnel to respond more efficiently and effectively, while also lowering overall cost for the end user. While surveillance technologies such as radar, thermal imaging and visible cameras, or video analytics work well on their own, utilising all of these options together provides an advanced perimeter detection system. For example, ground surveillance radar can detect possible threats beyond the fence line as they approach and send a signal to pan-tilt-zoom (PTZ) cameras, triggering them to slew to a specific location. From there, embedded analytics and visible cameras can further identify objects, notify authorised staff, and collect additional evidence through facial recognition or high-quality photos. 2. Automatic response systems Once an intrusion attempt is discovered, it is important to act fast. Organising a response system that can initiate actions based on GPS location data, such as the slewing of PTZ cameras, automated intruder tracking or activated lighting sensors, greatly increases staff’s situational awareness while easing their workload. For instance, thermal imagers deployed in conjunction with video analytics can be used to generate an initial alarm event, which can then trigger a sequence of other security equipment and notifications for personnel to eventually respond to. Having all of this in place essentially lays the entire situation out in a way that allows responders to accurately understand and evaluate a scene. Power stations located near bodies of water can use thermal cameras to create a “thermal virtual fence” in areas where they are unable to utilise the protection of a physical fence or wall 3. Deterring suspicious activity After the designated auto-response mechanisms have activated and done their job, it is time for responders to acknowledge and assess the situation. From here, authorised personnel can take the next appropriate step toward defending against and delaying the threat. Deterring suspicious activity can be achieved through real-time two-way audio, a simple but powerful tool. Often, control room operators can diffuse a situation by speaking over an intercom, telling the trespasser that they are being watched and that the authorities have been notified. This tactic, known as ‘talk down’, also allows officers to view the intruder’s reaction to their commands and evaluate what they feel the best next step is. If individuals do not respond in a desired manner, it may be time to take more serious action and dispatch a patrolman to the area. 4. Delay, defend, dispatch and handle The possible danger has been identified, recognised and evaluated. Now it is time to effectively defend against current attacks and slow down both cyber and physical perpetrators’ prospective efforts. Through the use of a well-designed, open platform VMS, security monitors can manage edge devices and other complementary intrusion detection and response technologies, including acoustic sensors, video analytics, access control and radio dispatch. A robust VMS also enables operators to control functions such as video replay, geographical information systems tracking, email alerts and hand-off to law enforcement. With the right combination of technologies, facilities can take monitoring and evidence collection to the next level The primary purpose of the delay facet of the overall perimeter protection strategy is to stall an attempted intrusion long enough for responders to act. Access control systems play a key role in realising this objective. When a security officer sees a non-compliant, suspicious individual on the camera feed, the officer can lock all possible exits to trap them in one area all through the VMS. 5. Intelligence: Collect evidence and debrief More data and intelligence collected from an event equals more crucial evidence for crime resolution and valuable insight for protecting against future incidents. With the right combination of technologies, facilities can take monitoring and evidence collection to the next level. One innovative resource that has become available is a live streaming application that can be uploaded to smart phones and used for off-site surveillance. This app gives personnel the power to follow intruders with live video anywhere and allows operators to monitor alarm video in real-time. Geographic Information System (GIS) maps are computer systems utilised for capturing, storing, reviewing, and displaying location related data. Capable of displaying various types of data on one map, this system enables users to see, analyse, easily and efficiently. Multi-sensor cameras, possessing both visible and thermal capabilities, provide high-contrast imaging for superb analytic detection (in any light) and High Definition video for evidence such as facial ID or license plate capture. Integrating these two, usually separated, camera types into one helps to fill any gaps that either may normally have. Still, in order to capture and store all of this valuable information and more, a robust, VMS is required. Recorded video, still images and audio clips serve as valuable evidence in the event that a trial must take place to press charges. Control room operators can use data collection tools within their VMS to safely transfer video evidence from the field to the courtroom with just a few clicks of their mouse. More advanced video management systems can go a step further and package this data with other pertinent evidence to create a comprehensive report to help ensure conviction.

When comparing specifications among a range of similarly featured video surveillance cameras, NVRs or monitors, it can be difficult to ascertain which of the devices truly has the best performance and/or quality. John Grabowski, National Sales and Marketing Manager of JVC Security Division, poses some questions for consideration: Can the human eye actually see a difference in image quality between one camera that offers 700 lines of resolution and another that offers 600 lines? Or can it see the difference in image quality between a 3 megapixel camera and a 5 megapixel camera? What about performance characteristics such as latency or colour accuracy? In determining these specifications, one must also ask what has influenced or interfered with the measurement. Performance measurement through MTBF Today’s video surveillance components use highly advanced technology, making the evaluation process even more difficult. While impartial testing of the equipment on oscilloscopes and wave form monitors, shoot-outs or other side-by-side comparisons can help bring clarity to the evaluations, one solid metric for quality and performance is MTBF (mean time before failure) figures with failure rate (FR) data. These figures can help provide a clear guide for product lifetime expectations. For example, a surveillance camera with a published MTBF figure of 90,000 hours has more than 10 years of 24/7 usage. Engineered to a higher standard MTBF can be viewed as a quality standard as well as a planning metric. Although many companies build security products to meet specific price points, the best companies engineer their video surveillance products with robust designs that will endure and address the specific needs and conditions of the surveillance market. To a great extent, the longevity of key components such as integrated circuits and capacitors determines the MTBF of the products in which they are used. However, better parts only provide part of the key to better reliability. The internal temperature of products significantly affects MTBF as well. As electronic components have become more compact, the temperature of smaller, more constricted circuits and other components has become almost impossible to measure. Preventing thermal issues through thermal analysis and design requires careful electronic and mechanical engineering. This is accomplished early in development which makes it easier to visualise heat in every part of every component, thereby enabling engineers to prevent thermal issues and create products with significantly greater reliability. The best video surveillance products are designed to endure the specific needs of the surveillance market Companies that publish MTBF specifications generally arrive at those figures through extensive product testing, valuing the MTBF of individual components and by past experience with similar products. Some manufacturers elect to calculate MTBF based on strict military standards. Life-Cycle costs The initial cost of a video surveillance system is only a portion of the total cost of ownership (TCO). While a low price and warranty may make a camera with a lower MTBF seem attractive, this can be a mistake. Should the product fail within the warranty period, rather than repair the device, many manufacturers will simply replace a relatively low-priced item like a video surveillance camera. However, the process of replacing that camera can be very expensive for the end user or the system integrator. The cost of sending a technician up a ladder to replace a failed video surveillance camera often costs more than the camera itself. Plus, it is important to consider the potential damage or theft during downtime while the camera is not providing surveillance. High rated MTBFs can help reduce these replacement and maintenance costs over the life of a video surveillance system. The robust equipment can better withstand shock and vibration, extreme temperatures, moisture and dust, power fluctuations and offer significantly lower life-cycle costs through reduced down time. High rated MTBF products also create an improved overall value and a better return on the investment. For example, cameras can account for anywhere from 30 to 50% of the initial cost of a system and therefore should be selected with care. A camera’s proven reliability can help defer costly replacements during the system life cycle and improve utilisation. In short, product reliability can optimise capital, operations and maintenance expenditures while improving the safety and security of the environment. Today, there is an abundance of information available to help users make the best selections for their needs. By providing MTBF data, video surveillance manufacturers can make it easier for the user to make decisions.
