Making Sure Daily Operations Run Smoothly
Making Sure Daily Operations Run Smoothly

Although the Barcelona Metro (Transports Metropolitans de Barcelona, TMB) surveillance system has on occasion helped police to catch an organized group of thieves, crime was not the reason TMB started installing cameras twelve years ago. With over one million people traversing the city each day on TMB trains, with stops at more than 100 stations, Barcelona’s Metro authorities needed to make sure that things were running smoothly and safely and that commuters could get where they needed to go. The first phase of the project entailed installing an analog CCTV system throughout twenty metro stations. Each station contained eight cameras and a small compartment for an operator, who viewed the live streams locally on two monitors. The footage of each camera was recorded twenty-four hours per day and saved on a digital video recorder (DVR) for a period of three or four days. The system proved itself a success. It streamlined daily operations and helped to combat delays allowing prompt response times to serious incidents. TMB therefore decided to instigate a second installment phase: The system would come to comprise thirty cameras per station. Naturally, this was too much for just one locally-based station manager, and alternative solutions were sought. The maturation of effective metro management One of the first things that TMB did, in addition to increasing the number of cameras in each station, was to enhance their central control room with a customized video management system (VMS) and matrixes of screens for viewing video. The control room would contain one area for viewing live video and one for examining recordings. In this way, operators and security personnel would be able keep a close watch on the operations and safety of the Barcelona Metro. Due to the fact that recording the public in metro stations and saving it for a few days might make images vulnerable to misuse, TMB decided to enlist the help Indra Sistemas, S.A., Spain’s leading information technology (IT) company. In order to offset the possibility that images could be leaked to the public or tampered with, Indra was commissioned to create a customized VMS that would encrypt the camera images and make it impossible to freeze them. This VMS system thus has come to help protect the public from the potential abuse of the TMB surveillance system while at the same time enabling the metro system to run more smoothly for commuters. Another major improvement that TMB made to their system was to make their station managers mobile. Through the use of personal digital assistants (PDA), the once stationary operators are now able to receive camera footage and instructions from the central control room about the location and nature of various incidents in metro facilities. Traveling in pairs, these impromptu personnel can promptly address problems and make sure that trains are running smoothly and that people riding the metro are safe.     TMB and TKH Security Solutions work closely to update the Barcelona Metro surveillance network Evolving into IP Throughout the course of this surveillance system project, technology has, of course, continued to advance, and TMB was determined to keep pace with the times. Therefore, as TMB restructured and expanded its surveillance system into a larger and more complex network, it also started looking into what kinds of technology would best suit its needs. TMB wanted, for example, to continue to record all of its camera footage twenty-four hours per day and store the images for three or four days. Yet with around 3300 cameras throughout the city, it became all too clear that the system had outgrown its analog DVR apparatus. In an effort to maintain a state-of-the-art system, TMB sought the most superior IP recording solution for the application and, in the end, found the Siqura recording solution to be the best recorder for the job. Working together to guarantee optimal performance Although the Siqura recording solution would come to record the footage of the metro’s multitude of camera streams, Siqura solutions from TKH Security Solutions were not unfamiliar to TMB. From the very beginning of the project, fiber optic transmitters and receivers from TKH Security Solutions, a manufacturer of advanced IP and fiber video surveillance equipment, were used for streaming data and video. These fiber solutions had been shown to reliably provide quality video in each station, and TMB expected the same from the Siqura recording solution. Consequently, TMB and TKH Security Solutions have continued to work closely with each other over the years to expand and update the Barcelona Metro surveillance network. Eventually, as TMB moved increasingly towards IP solutions, it also incorporated Siqura encoders into its system to transmit IP streams. Business relations such as this as well as that between TMB and Indra are integral to making sure that a surveillance system is working optimally and doing what it is supposed to do, and in this case, that is ensuring the safety and smooth operation of the Barcelona Metro. A second glance at surveillance It’s true, operators working in the TMB central control room can recognize all the pickpockets ambling the underground. Yet, countering petty theft is not the purpose of this CCTV system. Today, the TMB surveillance network facilitates the operation and safety of one of the largest metro systems in Europe. It is designed and implemented in such a way so as to protect the privacy of the public as well as to keep commuters safe, all the while guaranteeing that trains will run on time.

Securing A Strategic City With New Surveillance Systems
Securing A Strategic City With New Surveillance Systems

Known to some as the home of mariachi music and to others as the home of a great number of renowned writers and artists, Guadalajara is without a doubt a major cultural hub of Latin America. It is also the second largest city in Mexico and the capital of the state of Jalisco, making Guadalajara a strategic place for both businesses and government. It is therefore not surprising that the municipality is modernising its internal revenue and land registry offices with new IP-based CCTV surveillance systems. Safely transferring fundsThe surveillance system is intended to ensure the secure transfer of funds and to protect the safety of the office staff during daily operations at nine different offices. The installed cameras therefore monitor areas where monetary transactions occur, such as at the tax collection windows, as well as various personnel workplaces. Heading up the project is the municipality of Guadalajara. A select group of the city's civil servants are working with a local support team of engineers from the international distributor, Rios Representaciones Internacionales, and the Mexican installer company, Ingeniería en Telecomunicaciones e Informática (ITISA). Together, they are setting up a centralized video surveillance network. The system will register the activities occurring in each of the buildings. Working alongside the core deployment team is TKH Security Solutions USA, manufacturer of advanced video surveillance solutions marketed under the Siqura and Optelecom brand names. TKH Security Solutions USA is providing cameras, storage, software, and support.A Siqura solutionUsing the existing IT network and Cisco switches, engineers from Siqura and the tax collection office IT personnel have designed and deployed a virtual LAN (VLAN) for the security system. VLAN enhances network performance as well as the security of the system. It connects the offices through a fiber link. From a variety of locations and situations, Siqura IP cameras will transmit image material to the video management system (VMS), Siqura VMS Pro, at a centralized control room. From there, operators can ensure the safety and security of both personnel and property.Siqura VMS Pro is a multiserver, multi-user IP surveillance management system used for monitoring real-time and recorded video, audio, and text data, and to control cameras and I/O devices. The software supports surveillance systems consisting of digital IP cameras and recorders in IP surveillance networks. Through the intelligent search options and event handling included in Siqura VMS Pro, relevant recordings will be saved on one of ten hardware network video recorders (Siqura i-NVR Compact). Ultimately, this enables personnel to verify the immediate safety of the tax collection offices, their employees and visitors, as well as to use video images for forensic verification when necessary.A successful startAlthough the implementation of the project is still underway, the system is already up and running in two offices, with pleasing results. "TKH Security Solutions USA has provided excellent support in designing, configuring, and installing the software and the cameras," said Raul Rios, director of Rio's Representaciones Internacionales. "The equipment was tested in the local network. We enlarged selected material to test the image quality and examined the cameras' ability to cope with various lighting conditions. After adjusting the lens, the system performance has proven to be perfect."

Le Meurice Hotel Strengthens Its Security With Samsung Cameras And Digital Video Recorders
Le Meurice Hotel Strengthens Its Security With Samsung Cameras And Digital Video Recorders

Le Meurice can claim to have the highest occupancy rates, turnover and profitability of all of the seven Parisian palaces. Ideally located in the very heart of Paris and facing the Tuileries garden, Le Meurice offers 160 luxury rooms located though out its seven floors. The hotel's bar, two restaurants, several lounges and function rooms are part of the space open to the general public, as well as numerous lobbies and stairways. The hotel is accessible 24/7. Several security guards are permanently deployed at the hotel with one of the security guards tasked to keep a close eye over the video surveillance monitors. This service is subcontracted to Commodore, a company that has specific experience and know-how in respect to hotel security. The hotel wanted to upgrade its existing CCTV to both extend the areas covered and record higher quality images. A detailed risk assessment was carried out, followed by the production of a specification of the hotel's technical requirement with a proviso that the chosen supplier must have proven track record of reliability and post sales technical support. Of prime importance in the design of the system was that the Le Meurice has listed interior architecture, which greatly limited the cabling options as well as the size and appearance of cameras. In fact, the existing cabling had to be re-used in the new system. New cameras were installed to monitor floor access doors from the stairs so that people can be viewed entering and leaving. All entrances to the whole non-private interior space are now monitored, with a total surface of about 10,000 m² out of a total of 35,000 m². The CCTV system covers all public spaces and circulation areas including, all stairways, kitchens and laundry rooms, as well as private areas such as the inner courtyards and the roof. Cameras are deliberately visible with a view to deterring any unwelcome activity. One of the key areas being monitored is a jewelery gallery where items from prestigious Parisian jewellers are on display.  A gallery displaying items from prestigious Parisian jewellers is one of the key areas being monitored A total of 68 analog cameras were already installed and many of these have been replaced with higher-quality models. The system is now comprised of 94 cameras, which includes Samsung analog cameras, speed domes and some small bullet cameras. The requirement for all of these cameras was that they had to be aesthetically acceptable whilst acting as a powerful deterrent. In addition, image quality had to be of a consistent high quality even in backlight conditions. The Samsung SID-460 mini dome was chosen for its ability to generate very high quality color images at 580 TV lines resolution as well as 3-axis positioning of its varifocal lens. The SID-460 incorporates Samsung Super Noise Reduction (SSNRII) technology, which eliminates image noise in low light conditions. This allows consistent high quality color reproduction even in very low-light conditions, as well as saving up to 70% on the recording device and the reduction of bandwidth requirements when networking. All cameras are connected over coaxial cables to Samsung 32 channel SVR-3200 DVRs installed in a control room secured with access control. These recorders were chosen for their high processing and storage capabilities. Just three of the SVR-3200 are required and provide a significant reduction in heat dissipation from the previous equipment. 500GB video storage versions of the SVR-3200 were ordered and then upgraded to their full 8TB internal capacity by using easy to install HDD upgrade kits. The SVR-3200 is supplied with license-free Centralized Management Software (CMS), which gives users full control of DVR functions from anywhere on the network. Images from all of the cameras are recorded at real-time 25 frames per second when triggered by motion detection. The high quality images can be stored for up to 15 days thanks to the high storage capacity of the SVR-3200. Live images are displayed and monitored in the guardhouse on three 19-inch monitors with cameras grouped by area. Motion detection alarms on external cameras trigger an automatic display of an intrusion event with operators being able to look at pre-intrusion images. Security personnel use a control keyboard with a joystick to control the cameras. The installation was successfully completed without any delays or hitches and the hotel now has a CCTV system which is capable of capturing, recording and storing images to their required standard. The recently installed Samsung cameras and DVRs are supplied with a three-year warranty guarantee whilst a spare hard disk is kept on site ensuring a fast replacement should the need arise. Access to images via the hotel's PCs is regarded as a definite bonus in that it is a very convenient and efficient method of viewing or searching for images. Equally important, the system was designed with the future in mind and additional cameras can therefore be easily and quickly installed in the future if required. The client is very happy with the quality of the upgraded CCTV system and considerable goodwill has been created between everyone involved in the success of the project including the engineering firm of AB Associates, the system builder, Stentorius and the installer, AM Sécurité.
