Founded 175 years ago, the Université Libre de Bruxelles (ULB), just like its home city, is intrinsically cosmopolitan, and a gateway to Europe and the world. This thoroughly multicultural university, that offers programs in all disciplines and at all levels, is also a major research center recognised by the international academic community. This free-thinking university, a private institution recognised and subsidised by the government, has remained true to its original ideals: it is an institution that is committed to defending democratic and humanist values. A true city within a city, the University has three campuses in Brussels that welcome nearly 24,000 students each year. The main campus, in Ixelles (Solbosch), is home to the central administration and most social sciences faculties, as well as the Ecole Polytechnique. One kilometre away is the de la Plaine Campus, and the faculties of science and pharmacy. The faculties of medicine and public health are all located at the Anderlecht Campus (future health hub), right next to the Hôpital académique Erasme (ULB university hospital). The University also has a campus in the Wallonia city of Charleroi, at the Biopark hub, specialising in biotechnology.

The business challenge

The Université Libre de Bruxelles has decided to focus on security on its campuses by implementing a video surveillance system, and controlling access to restricted and critical areas.

Located in the heart of Brussels, ULB is accessible to the public, i.e., vulnerable to risky situations, especially after business hours, and during evenings and weekends. This pioneer in the installation of emergency phones has made security on its campuses a strategic objective. To meet this objective, the University's security department installed a system to monitor and control access to restricted and critical areas (mainly buildings). As part of this plan, the ULB has placed cameras in strategic locations (including the pass-controlled doors to each building and at the emergency phones that were custom-designed for the University) that then send the images to a control centre. At the time of the switch from analogue to digital, the initial installation did not have the configuration flexibility of an IP system needed to meet the requirements set by the ULB.

The ULB security teams have opted for recent IP developments in the field of video protection. They have defined new project specifications to support the implementation of a new and improved solution that also would enable them to keep the original system. This solution must work efficiently—especially with the original star-type telephony network—while being more decentralised, and offering the possibility for upgrades in terms of volume and integration of new technologies.

"We will expand our system in the future by adding new buildings to the system. The great thing about Omnicast is that the introduction of new cameras is done on a case-by-case basis"

ULB's security system requirements

"To make crime unwelcome on campus," answered Jean-Philippe Charlier, ULB security manager, when asked about his team's objective. To do so, the system implemented must allow doors to be remotely managed and controlled, for example, on a schedule-based system for student access outside of course hours. It must also allow anyone in danger or at risk to alert the control centre, which determines how to react based on the images received and the emergency level. In order to be thoroughly efficient, the system must provide a 24/7 overview of the campuses, and must synchronise the various cameras to track any suspicious activity (the path taken by a suspect, for example). The security agents decide either to intervene immediately or to send the film to the police at a later date.

The easy creation and modification of user profiles is also important. Belgian law defines user types with different rights, i.e., not everyone is authorised to see the live images. Another requirement: all security-related calls must be directed to the control centre, located on the Solbosch Campus. Automatic response to calls made from any of the emergency phones located across the campuses, all of which allow for visual monitoring through an integrated IP camera, an intercom, as well as an alarm system that allows security agents to quickly intervene, is yet another requirement.

And, finally, the University wants an open technology that is easy to upgrade and integrate into an existing system.

The perfect solution

The integration of Synergis and Omnicast allows the emergency phones to work by using multiple contacts and relays
The intercom system allows operators, to immediately view the image received and intervene

Once the project specifications were set, and after a first installation that did not meet all the requirements, the ULB turned to Damovo, with which the university has worked for over 15 years on the telephony system and which is familiar with the different levels of the system. Given the requirements for opening and operating the existing star-type network, and the transition from analog to IP, Damovo proposed the Genetec Omnicast video surveillance solution for its open architecture and its capacity to manage various user profiles, as security needs are not the same across all campuses.

The first stages of installing the Genetec solution, which involved four cameras with almost-immediate start-up, convinced the University's security department. One hundred and twenty cameras (mostly Bosch) are now operational—including 80 on the main Solbosch campus. The Genetec Omnicast solution optimises camera functions, even on the oldest models. "What we liked the most was the ability to use our original cameras and existing system for a whole host of new functions," specified Jean-Philippe Charlier, ULB security manager.

Four servers installed at different locations (for security reasons) store the images. Example:

The "automatic directory failover" function is integrated within ULB, which helps keep the video surveillance system permanently online, regardless of the status of the network.

The images are stored on large-capacity RAID-type hard drives, limited only by the Belgian Privacy Commission's legislation concerning duration of image conservation.

Fourteen client stations (including 11 screens) located at the control centre operate 24/7 and are supervised by Damovo. Quick intervention is guaranteed by a service contract that also stipulates software upgrades of all its components.

The integration with the intercom systems (Stentofon IP Station), managed in the form of Omnicast alarms, is one of the major advantages of Genetec's Software Development Kit (SDK) solution. The intercom system allows operators, on receipt of a call from a given door, parking barrier or emergency phone, to immediately view the image received and intervene as quickly as possible.

"We won't use grid zones, but if a new building is built, or we identify a potentially dangerous zone, we will petition the authorities for new cameras"

The permanent solution provided by the overall video surveillance system must be a logical response to a need expressed by the users. "We won't use grid zones, but if a new building is built, or we identify a potentially dangerous zone, we will petition the authorities for new cameras." And this is easily done thanks to the easy integration of Genetec's Omnicast solutions.

The Gosselies local archiver records the images to minimise bandwidth use. Even when live images are viewed by several operators, the efficiency of the multicast IP protocol helps reduce the bandwidth used by the ULB network to a strict minimum. The operators, located in Brussels, control the cameras in priority sequence thanks to the well-organised user structure in Omnicast.

The benefits

The use of Genetec's Omnicast solution, installed five years ago, is paying off for the ULB. Regarding users, the main asset is the great simplicity and flexibility of use offered by Omnicast on a day-to-day basis. Its open architecture is especially useful when defective equipment must be replaced or new equipment installed.

The optimised synchronisation functions of the various cameras are a real asset for tracking suspicious activities and provide support to the police department as needed. The ULB security team can now preview images much more easily and quickly than before, and review any significant event recorded. As a result, cooperation with the authorities has been strengthened, as the latter can now be sent specific information on security incidents, since the Genetec systems guarantee the full reliability of the data. "They appreciate our help in cases of theft or assault on campus, and the videos we record are a great help to them in their investigations."

The system has also proven to be efficient by allowing authorities to defuse potentially critical situations, and is well perceived by the students and their parents, who see it as a real service. This helps increase the feeling of security across the entire university community.

Finally, the video surveillance strategy adopted by the ULB, and its choice of Genetec solutions, have strengthened its pioneering image in terms of security, especially in the academic sector, because ULB is the only university of its kind with a comprehensive security department dedicated exclusively to campus security and surveillance.

"We will expand our system in the future by adding new buildings to the system. The great thing about Omnicast is that the introduction of new cameras is done on a case-by-case basis. This flexibility really allows us to do what we want," concluded Jean-Philippe Charlier.

The integration of Synergis and Omnicast allows the emergency phones to work by using multiple contacts and relays. The HID-over-IP controls enable maintenance and monitoring over a distance of several kilometres between the different sites.

This also simplifies integration with other systems, such as ControlMaestro, in order to track events on existing remote management screens. Programming is made much easier by having a single provider for Synergis and Omnicast systems.

Panasonic AI-driven cameras empower an expanding vision of new uses
Panasonic AI-driven cameras empower an expanding vision of new uses

Imagine a world where video cameras are not just watching and reporting for security, but have an even wider positive impact on our lives. Imagine that cameras control street and building lights, as people come and go, that traffic jams are predicted and vehicles are automatically rerouted, and more tills are opened, just before a queue starts to form. Cameras with AI capabilities Cameras in stores can show us how we might look in the latest outfit as we browse. That’s the vision from Panasonic about current and future uses for their cameras that provide artificial intelligence (AI) capabilities at the edge. Panasonic feels that these types of intelligent camera applications are also the basis for automation and introduction of Industry 4.0, in which processes are automated, monitored and controlled by AI-driven systems. 4K network security cameras The company’s i-PRO AI-capable camera line can install and run up to three AI-driven video analytic applications Panasonic’s 4K network security cameras have built-in AI capabilities suitable for this next generation of intelligent applications in business and society. The company’s i-PRO AI-capable camera line can install and run up to three AI-driven video analytic applications. The AI engine is directly embedded into the camera, thus reducing costs and Panasonic’s image quality ensures the accuracy of the analytics outcome. FacePRO facial recognition technology Panasonic began advancing AI technology on the server side with FacePRO, the in-house facial recognition application, which uses AI deep learning capabilities. Moving ahead, they transitioned their knowledge of AI from the server side to the edge, introducing i-PRO security cameras with built-in AI capabilities last summer, alongside their own in-house analytics. Moreover, in line with the Panasonic approach to focus more on collaboration with specialist AI software developers, a partnership with Italian software company, A.I. Tech followed in September, with a range of intelligent applications, partially based on deep learning. Additional collaborations are already in place with more than 10 other developers, across the European Union, working on more future applications. i-PRO AI-capable security cameras Open systems are an important part of Panasonic’s current approach. The company’s i-PRO AI-capable cameras are an open platform and designed for third-party application development, therefore, applications can be built or tailored to the needs of an individual customer. Panasonic use to be a company that developed everything in-house, including all the analytics and applications. “However, now we have turned around our strategy by making our i-PRO security cameras open to integrate applications and analytics from third-party companies,” says Gerard Figols, Head of Security Solutions at Panasonic Business Europe. Flexible and adapting to specific customer needs This new approach allows the company to be more flexible and adaptable to customers’ needs. “At the same time, we can be quicker and much more tailored to the market trend,” said Gerard Figols. He adds, “For example, in the retail space, enabling retailers to enhance the customer experience, in smart cities for traffic monitoring and smart parking, and by event organisers and transport hubs to monitor and ensure safety.” Edge-based analytics offer multiple benefits over server-based systems Edge-based analytics Edge-based analytics offer multiple benefits over server-based systems. On one hand, there are monetary benefits - a cost reduction results from the decreased amount of more powerful hardware required on the server side to process the data, on top of reduction in the infrastructure costs, as not all the full video stream needs to be sent for analysis, we can work solely with the metadata. On the other hand, there are also advantages of flexibility, as well as reliability. Each camera can have its own individual analytic setup and in case of any issue on the communication or server side, the camera can keep running the analysis at the edge, thereby making sure the CCTV system is still fully operational. Most importantly, systems can keep the same high level of accuracy. Explosion of AI camera applications We can compare the explosion of AI camera applications to the way we experienced it for smartphone applications" “We can compare the explosion of AI camera applications to the way we experienced it for smartphone applications,” said Gerard Figols, adding “However, it doesn’t mean the hardware is not important anymore, as I believe it’s more important than ever. Working with poor picture quality or if the hardware is not reliable, and works 24/7, software cannot run or deliver the outcome it has been designed for.” As hardware specialists, Figols believes that Panasonic seeks to focus on what they do best - Building long-lasting, open network cameras, which are capable of capturing the highest quality images that are required for the latest AI applications, while software developers can concentrate on bringing specialist applications to the market. Same as for smartphones, AI applications will proliferate based on market demand and succeed or fail, based on the value that they deliver. Facial recognition, privacy protection and cross line technologies Panasonic has been in the forefront in developing essential AI applications for CCTV, such as facial recognition, privacy protection and cross line. However, with the market developing so rapidly and the potential applications of AI-driven camera systems being so varied and widespread, Panasonic quickly realised that the future of their network cameras was going to be in open systems, which allow specialist developers and their customers to use their sector expertise to develop their own applications for specific vertical market applications, while using i-PRO hardware. Metadata for detection and recognition Regarding privacy, consider that the use of AI in cameras is about generating metadata for the detection and recognition of patterns, rather than identifying individual identities. “However, there are legitimate privacy concerns, but I firmly believe that attitudes will change quickly when people see the incredible benefits that this technology can deliver,” said Gerard Figols, adding “I hope that we will be able to redefine our view of cameras and AI, not just as insurance, but as life advancing and enhancing.” i-PRO AI Privacy Guard One of the AI applications that Panasonic developed was i-PRO AI Privacy Guard Seeking to understand and appreciate privacy concerns, one of the AI applications that Panasonic developed was i-PRO AI Privacy Guard that generates data without capturing individual identities, following European privacy regulations that are among the strictest in the world. Gerard Fogils said, “The combination of artificial intelligence and the latest generation open camera technology will change the world’s perceptions from Big Brother to Big Benefits. New applications will emerge as the existing generation of cameras is updated to the new open and intelligent next generation devices, and the existing role of the security camera will also continue.” Future scope of AI and cameras He adds, “Not just relying on the security cameras for evidence when things have gone wrong, end users will increasingly be able to use AI and the cameras with much higher accuracy to prevent false alarms and in a proactive way to prevent incidents." Gerard Fogils concludes, “That could be monitoring and alerting when health and safety guidelines are being breached or spotting and flagging patterns of suspicious behaviour before incidents occur.”
