Technology is changing the look and function of today’s security control rooms. Old-school CRT (cathode-ray tube) monitors are giving way to the thinner, flat screen monitors in the control room environment, but the transition is gradual. Randy Smith of Winsted still sees many control rooms that need to make the conversion, which is a boon to his company’s business. Furniture today is designed differently to accommodate the thinner monitors, often with larger screens. Need for integrated rack systems With the increase of IP-based systems comes the need for integrated rack systems that include advanced functionality such as cable management, adds Jim Coleman, National Sales Manager, AFC Industries. Server rooms are environmentally controlled by cooling systems and power systems monitored on the IP network. Low-profile flat screens allow centres to utilise space vertically, thus creating a smaller footprint for the consoles. Additionally, with IP-based systems, workstations will have a smaller footprint because there is less cumbersome equipment. In most cases the servers are stored in a secured, climate controlled environment to eliminate overheating of the servers and maintain their security, says Coleman. This environment also helps with cable and power management. AFC builds technical furniture racks that adhere to the precise needs of computer network server room operators. The company designs and fabricates LAN workbenches with versatile functionalities, and server room workstation racks that are scalable. There is a complete line of IT workbenches, IT computer racks and computer server rack mounts with flexible mounting options. In most cases the servers are stored in a secured, climate controlled environment to eliminate overheating of the servers and maintain their security Flexible control room designs Matko Papic, Chief Technology Officer of Evans Consoles, says the transition from bulky CRT equipment to flat-screen (lower profile) monitors was a major disruption in control room design; it changed the whole dynamic. Another evolution is the use of IP video streaming, which allows more flexibility in manipulation of audio-video content, and requires more flexible control room designs. Another shift, driven by larger, higher-definition monitors, is a shift to fewer monitors that display more information. Instead of a smaller monitor for each information stream, larger monitors now consolidate that information into “dashboard” displays. Looking ahead, control rooms will need to be more flexible, both in the initial design and the ability to adapt to changing technology, says Papic. Legacy customers who are currently using PCs may be moving to more remote applications. Sit-stand equipment will continue to be increasingly prevalent. “There will be more emphasis on flexibility, technology integration, and the ability to change over the life of the system,” says Papic. Consolidation of multiple operations into a single system A trend in security is consolidation of multiple physical operations into a single system, says Papic. As a result, more customers are taking more interest in alarm management and situational awareness. How is the technology being used in terms of alarm triggers? How can the systems react rapidly and provide information to a larger audience in the control room? These questions impact how control rooms are designed, and Evans Consoles can adapt lessons learned from other markets to these trends in the security arena. Greater use of technology is inevitable, says Coleman of AFC Industries. “It is virtually impossible for humans to monitor all security data at the street level in our cities,” he says. “As computers become more powerful and their programs more all-encompassing, we will see a greater shift to robotic and technology uses that will provide enhanced monitoring capabilities and safety Read our Control Rooms series here
Selecting the optimum power supply for a system is critical to an installation When it comes to selecting power supplies, knowledge is power. Determining the power requirements of every systems product, taking into account their integration with one another is critical to ensure that you are selecting and installing the power solutions most appropriate for your installation. Such information will enable you to select the power supplies that will be required to keep your security system running efficiently in the long run. Paul Rizzuto, Technical Sales Manager, Altronix Corp outlines some of the key factors to consider when choosing the right power solution for security installations - including those of video surveillance systems and access control systems - and fire alarm systems. Questions to consider when selecting the optimum power supply Before commencing the evaluation and selection process, three fundamental questions/issues need be addressed:Approvals and conformance to norms: Are there any specific agency approvals that the installation must conform to?Each state, county and even municipality has their own requirements regarding agency approvals. There are a variety of compliance issues such as UL listings for video, access control and fire/life safety that need to be adhered to along with specific local codes. It's imperative that you check with the local AHJ (Authority Having Jurisdiction) to find out what agency listings you must conform to during the design process to assure your security system is in compliance before installing any components and power supplies. Features required: What are the application specific features required for the installation? Selecting power supplies for a security or fire alarm system is a complex process due to a number of variables Before starting the design process, a comprehensive analysis of the facility's security systems are required to determine feature sets of the power supplies. Up until recently, selecting power supplies often required the need to combine various components to deliver the functionality desired. For example, does the system need battery back-up in case of a power failure? All that has changed with the introduction of a new breed of integrated power solutions that deliver both cost and installation advantages. Quantity, location and power requirements of the security system componentsWhat is the number of devices in the system, the power requirements for each, and their physical location?This information is necessary to determine the size and quantity of the power supplies, how many security devices they will run, and where they will be physically located. It is always a good rule of thumb to add 20% more power to your calculations as a safety factor. Alarm signal generation is a key consideration when dealing with power consumption in fire alarms systems Dealing with power consumption issues in fire alarm systems Power consumption is a primary issue when configuring fire alarm systems. One of the most critical considerations revolves around how alarm signals are activated. When an alarm condition exists, Notification Appliance Circuits (NAC) are output from the Fire Alarm Control Panel (FACP) to activate notification appliances such as strobes and horns commonly used to indicate an emergency situation. The number of notification appliances to be activated, along with the current draw for each device and its distance from the FACP, sometimes makes the deployment of NAC Power Extenders a necessary system component. For example, in large commercial installations or multi-tenant buildings, the total current draw of the notification appliances may well exceed the power output of the FACP. In these instances, one or more NAC Power Extenders need to be installed for those notification appliances where the wire runs are too long for the FACP to deliver sufficient power. Features to consider when selecting a NAC Power Extender: Number of Class A or Class B indicating circuits.Total power rating (ex. 6.5 amp, 8 amp or 10 amp).Number of Aux. power outputs with or without battery backup.Programmable outputs: SynchronizationTemporal Code 3Input to output follower mode.Enclosure capacity: Room for battery backupAmple knockouts and room for wiringAgency approvals UL, MEA, CSFM and FM.NAC Power Extenders are available with programmable features that maintain horn/strobe synchronization by either producing internally generated sync protocols utilized by major signal manufacturers, or by electronically repeating these sync protocols from the FACP outputs. Power supply requirements for access control systems - key standards to follow To ensure safety any device designated to lock or unlock an exit must be connected to the fire alarm systemAccess control systems manage entry and exit points at a facility by means of controlled locking devices. NFPA (National Fire Protection Association) requires that any device or system intended to actuate the locking or unlocking of exits, must be connected to the facility's fire alarm system so that all doors will release when an alarm signal is generated.To comply with NFPA requirements, there are two classifications of locking devices that need to be addressed: Fail-Safe and Fail-Secure. Fail-Safe locking devices such as magnetic locks release when they lose power. Fail-Secure locking devices such as electric strikes unlock when power is applied and may be manually released from inside a secured area. This determines the manner in which your power solution removes or provides power and the sequence and timing of each action.Access control power supplies come in both AC and DC versions and some provide multiple voltages simultaneously. Features include independently trigger controlled Fail-Safe/Fail-Secure outputs, power supervision, battery charging and fire alarm interface. Wall and rack mount models are also available.To comply with NFPA requirements, there are two classifications of locking devices that need to be addressed: Fail-Safe and Fail-Secure Some systems may also require the installation of panic hardware devices. Upon activation, the devices' high current power demand can reach up to 16amps, but not all power supplies can handle these high inrush currents. As a result, you need to specify a power supply designed for this type of application. Some operate a single panic hardware device and require optional modules to add features like timing functions, output relays, fire alarm disconnect, or power for additional panic hardware devices. Therefore, these "base" models almost always require additional modules to deliver the functionality you need and may not be cost effective. More advanced models offer integrated features and supply a comprehensive solution. In addition to the convenience of these integrated devices, they are highly cost efficient with respect to total cost of ownership and installation. Video surveillance systems - typical power consumption guidelinesVideo surveillance systems typically run 24/7/365 placing high demands on power supplies. These video power supplies need to deliver a clean and consistent source of 24VAC or 12VDC power to assure uninterrupted operation. Depending on the video component's specific power requirements and its location, there is a wide selection of power supplies to select from. They can be wall or rack mounted, designed for use indoors or outdoors, and feature AC or DC outputs. Configurations typically range from 1 to 32 outputs and some models offer additional features like 115 or 230VAC input with current ratings as high as 25 amps, power LED indicators, and PTC or fused protected outputs. Certain models provide both 24VAC and 12VDC to power both types of surveillance cameras simultaneously. Environmental conditions can affect the performance of video components and the power supply when situated outdoors A few additional variables to consider when selecting video surveillance power supplies include: Environmental conditions: Temperature differences due to change of seasons, day or night, can often be extreme and can have a direct affect on the performance of both the video components and the power supply when located outdoors. Enclosures for outdoor power supplies should be rated to withstand the elements.Ground Isolation: In some cases, the surveillance cameras are not equipped with internal electrical isolation. Should this be the case, it's important to specify a power supply with this feature. Video Transmission Systems: For years, the use of structured cable has been an inexpensive method for transmitting video and data between head end equipment and camera systems. The introduction of UTP transceiver hubs with integral camera power make it possible to transmit both video and data via structured cable along with the power needed for the cameras. This is accomplished via video balun/combiners which pass the power and data to the camera and send the video back to the head end equipment. New highly versatile devices with integral power provide system designers with a highly integrated solution. This new breed of integrated device greatly reduces the time and expense of configuring and installing separate components while helping to minimize bandwidth requirements for large security systems.

Intelligent solutions, such as those derived from artificial intelligence, help critical infrastructure organisations make sense of vast amounts of data. These integrated applications, such as advanced video analytics and facial recognition, can automatically pinpoint potential breaches and significant events, and send alerts to the appropriate personnel, departments, and agencies. These solutions can be powerful in unifying disparate command centre technologies, fusing critical data input from emergency calls and responder activity to enhance situational awareness. Electrical substations are particularly vulnerable (and in need of extra security) due to their role in power distribution and the nature of their equipment. The challenge power utilities worldwide are facing is finding an affordable solution, which can help detect, deter and facilitate an informed response to a substation security event. Data capture form to appear here! U.S. regulations In the United States, this need is furthered by the physical security mandate CIP-014 issued by the North American Electric Reliability Corporation (NERC), calling for identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address. CIP-014 identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address CIP-104 specifically calls for implemented security plans that include measures to deter, detect, delay, assess, communicate, coordinate and respond to potential physical threats and vulnerabilities. Manufacturers of video and other systems are designing products to serve the critical infrastructure market. For example, Dahua Technology offers explosion-proof cameras with a combination of rugged reliability and superior optics that is a fit for surveillance of explosive and corrosive environments, including chemical plants, refineries, and other facilities in the oil and gas industry. This explosion-proof series of cameras are housed in enclosures that are certified to the ATEX and IECEx standards for equipment in explosive atmospheres. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time. They are IP68-rated to prevent water and dust ingress. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time Video footage in extreme temperatures Another manufacturer, Videotec, offers a range of cameras and housings that provide video footage regardless of aggressive external factors, such as ice cold, scorching heat, desert sand, the force of sea or wind, total darkness, pollution, corrosion and even explosive agents. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sitesSightLogix smart thermal camera systems have been deployed to protect substations for electric utilities and other critical infrastructure facilities. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sites, ranging from copper theft to vandalism while also meeting regulatory compliance. At each substation facility, Thermal SightSensors are positioned along the perimeter, and are paired with a high-resolution pan-tilt-zoom camera for alarm assessment. When a Thermal SightSensor detects an intruder, the target’s location information is sent over the network to a SightTracker PTZ controller, which automatically zooms and steers PTZ cameras to follow the intruder. The target’s location is also displayed on a topology site map to provide real-time situational awareness. Alarms are sent to the utility’s 24-hour security operations centre, which will contact law enforcement in real time when unauthorised intrusions are detected. Integrated intrusion detection and lighting systems The Senstar LM100 hybrid perimeter intrusion detection and intelligent lighting system is simplifying security at one U.S. electrical utility company. For years, the utility company had integrated its perimeter intrusion detection and lighting systems. The company has now installed the Senstar LM100 which provides detection and lighting in one product and saves them over $80,000 per site. The savings are a result of the reduction of electrical requirements, conduit, grounding, and associated labor, as well as the removal of certain equipment from project scope that are required for the two-system integration. The Senstar LM100’s perimeter LED-based lighting acts as an initial deterrent. If an intruder persists and an attempt to cut, climb or otherwise break through the fence is detected, the closest luminaire begins to strobe, and an alert is sent via a security management system. The intruder knows immediately they have been detected and that their exact location is known by security and others in the vicinity.
Videotec presents NTX, the new IP68 stainless steel thermal camera, developed to provide an efficient and preventative surveillance system in the most critical environmental conditions. The NTX thermal camera offers temperature detection based on the 4 central pixels of the image, and with the advanced version, the temperature of a specific object can be measured at any point in the image by means of defining a specific area. As well as this, the radiometric functions offer the option to set a temperature limit, beyond which an alarm will be raised. Unwanted intrusions These functions are necessary where fire prevention is required or in applications such as monitoring industrial processes or critical equipment, where the ability to identify something quickly and accurately, thus preventing problems or failures and keeping intervention times to a minimum, is essential. Configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard NTX can export all the data necessary for a centralised management of video feeds, data and alarms, and make it available to VMS via the ONVIF Profile S and Profile Q communication protocols. Also, configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard. NTX allows exploiting fully the features and the advantages offered by the thermal camera. This includes the ability to raise an alarm and initiate immediate actions in order to prevent accidents or unwanted intrusions into monitored areas. Adverse environmental conditions The NTX camera is made entirely from electropolished AISI316L stainless steel and stands out thanks to its compact design and light weight. This, and the fact that it can be connected quickly, makes installation and maintenance easier. The modular support for wall, ceiling or parapet is supplied as standard. The NTX has obtained Lloyd’s Register Marine Type Approval certification for the maritime and naval sector and complies with the standard for railway applications. NTX is exceptionally resistant to corrosion and has a wide operating temperature range (from -40°C to +65°C). Its IP66/IP67/IP68, NEMA Type 4X and Type 6P grades guarantee maximum protection and optimal camera operation in even the most adverse environmental conditions. The fact that the NTX is extremely sturdy and of high quality means it is ideal for the most demanding applications in the marine and industrial sectors, in critical infrastructures, power plants and transport sector, including railways and motorway tunnels.
