Determining the power requirements of every systems product taking into account their integration with one another is critical

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 components

What 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:
- Synchronization
- Temporal Code 3
- Input to output follower mode.
Enclosure capacity:
- Room for battery backup
- Ample knockouts and room for wiring
Agency 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

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 ensure safety any device designated to lock or unlock an exit must be connected to the fire alarm system
Access 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 guidelines

Video 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.

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 supp
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.

MOBOTIX M7 platform provides more flexibility and computing power

It is an exciting time at German intelligent video company MOBOTIX, which has launched a next-generation platform that builds on their legacy of video at the edge while opening up the system to third-party partners that can build even more capabilities. MOBOTIX unveiled the new M7 platform and M73 camera at the MOBOTIX Global Partner Conference in Mainz, Germany, in October. MOBOTIX M7 is a powerful, decentralised and secure modular IoT-video system based on deep learning modules. The feedback has been “overwhelming,” says MOBOTIX CEO Thomas Lausten. The new technology will also be featured in the United States at the 2020 MOBOTIX Partner Summit in Hollywood, Fla., in January. A different video surveillance "What you see is a different way of doing video surveillance,” says Lausten. “Our focus on the edge is the difference between us and other companies.” The new MOBOTIX 7 open solution provides an “edge platform” that can be used for a variety of applications, which are provided as “apps” that leverage the platform’s hardware for specific uses, from object detection to face detection to people counting. The new M75 high-end camera incorporates the new platform. The MOBOTIX application programming interface (API) makes it possible for hundreds more apps to be developed over time Currently there are 19 apps available to empower various applications, and availability of the MOBOTIX application programming interface (API) makes it possible for hundreds more apps to be developed over time. If a MOBOTIX partner creates a new app for a specific project, “now he can use it not just for one project but can put it in the app store and sell it all over the world,” says MOBOTIX CTO Hartmut Sprave. Field Programmable Gate Array The new MOBOTIX platform uses Field Programmable Gate Array (FPGA) integrated circuits that provide flexibility and versatility to be adapted to a variety of needs, from deep learning, to higher resolution, or to use with a variety of sensors, such as color, black-and-white or night vision cameras, temperature sensors or microphones. “We can literally include any sensor requested by the market,” says Lausten. The new camera can also be used for age analysis, crowd management or traffic analysis. It can even be used for fire or biohazard detection, incorporating thermal sensors and deep learning. MOBOTIX have added to their legacy of video with a next generation platform Partnerships MOBOTIX developed its new platform in conjunction with Konica Minolta, which owns a majority share of the German manufacturer. The combined knowledge of the two companies created the new platform, with most of the engineering done in Germany. Konica Minolta provided an object detection algorithm, for example, and deep learning capabilities that are being used with the cameras. The two companies are also developing the business together. “They are rolling out our technology on their website throughout the world,” says Lausten. “We are basically part of a global development organisation.” MOBOTIX developed its new platform in conjunction with Konica Minolta The new platform is also completely compatible with legacy MOBOTIX systems: “We have added what we need to what we have,” says Lausten. Cybersecurity is a top priority for MOBOTIX. “With our camera, everything is under our control, every single line of code, and we do all the penetration testing and everything is safe,” says Sprave. In fact, MOBOTIX won the French "Trophée de la Sécurité 2019" Gold Award in the cybersecurity category for the MOBOTIX Cactus Concept, which refers to the fact that all the modules in the MOBOTIX system have “digital thorns” that protect them from unauthorized access. End-to-end encryption is used with no blind spots. Driven by cybersecurity Stronger cybersecurity and a focus on edge devices makes MOBOTIX inherently more cybersecure than a system of networked low-cost cameras, each of which could present a possible cyber-vulnerability. Stronger cybersecurity and a focus on edge devices makes MOBOTIX inherently more cybersecure The flexibility of the MOBOTIX platform expands its utility beyond security to include broader business functions. For example, the same camera that can detect criminals with face recognition can track where people are moving in a retail store, and even analyse age or demographics of customers to track buying patterns. “Cameras are required to think and process at the edge, and that is where we see a lot of focus going, driven by cybersecurity,” Lausten says. Lausten sees opportunity for even faster growth in the U.S. market, where they already have 30 or 40 partners. In the near term, there will be large opportunities provided by the U.S. trend toward “Chinese skepticism,” and cybersecurity concerns that have plagued the lower-cost Chinese imports. MOBOTIX products are proudly “Made in Germany.”

ATMs provide convenience for bank customers, but they have vulnerabilities

Most customers interface with their financial institutions using automated teller machines (ATMs), which have security issues. However, there are solutions available to combat all current security threats, and the cost of protection is coming down. The ATM industry is therefore in a position to minimise losses, while ensuring consumers continue to get the vital cash they need to lead their daily lives. It is important for the ATM industry to constantly innovate to meet new security challenges. So what innovations are we going to see in the next five years? Contactless technology Contactless technology will be a great help against ATM skimming, in which criminals steal personal information at ATM machines. Contactless is already being used in some European countries, and the number is increasing. Not having to insert a card into the ATM removes the opportunity to trap cards and also gets around the problem of “foreign” devices installed to read cards. So contactless technology, which some saw as the end of cash, can help make ATMs and cash more secure. Data capture form to appear here! Not having to insert a card into the ATM removes the opportunity to trap cards Biometrics are certain to be used increasingly to bolster ATM security. Finger, palm, vein, iris and facial recognition all have potential in this respect. Any of these may in the future be used with or without cards, PINs and one-time codes. Speed of operation in relation to biometrics could ultimately govern their use at ATMs. There may also be privacy issues that need to be addressed. The ATM vestibule environment must add security with proper security and surveillance equipment. ATM vestibules, or lobbies, are installed for many good reasons. For one, more convenient, 24/7 locations equals better customer retention for a bank, offering comfort and convenience. 24/7 access to ATMs, night drops, coin counters, online banking kiosks, and other self-service solutions are very much in demand. Second, ATM vestibules protect customers from inclement weather and provide a more comfortable banking environment (however, vagrancy can be an issue; therefore ATM vestibules should require card access). Security and surveillance solutions can’t just be for show. ATMs and crime A new crime wave is hitting automated teller machines (ATMs); the common banking appliances are being rigged to spit out their entire cash supplies into a criminal’s waiting hands. The common banking appliances are being rigged to spit out their entire cash supplies into a criminal’s waiting hands The crime is called “ATM jackpotting” and has targeted banking machines located in grocery shops, pharmacies and other locations in Taiwan, Europe, Latin America and the United States. Rough estimates place the total amount of global losses at up to $60 million. The protection of ATMs ATMs in supermarkets and pharmacies tend to be targeted because they may not be as well-protected, and store personnel likely would not know who is authorised to work on the ATM. In contrast, anyone approaching an ATM at a bank location would be more likely to be challenged. ATM jackpotting originated back in 2010 when Barnaby Jack, a New Zealand hacker and computer expert, demonstrated how he could exploit two ATMs and make them dispense cash on the stage at the Black Hat computer security conference in Las Vegas. Since then, malware has been created and made available on the “Dark Web” that can instruct an ATM to dispense all its cash on demand. ATM jackpotting ATM jackpotting is a combination of a physical crime and a cyberattack ATM jackpotting is a combination of a physical crime and a cyberattack. Typically, a criminal with a fake ID enters a grocery shop or pharmacy posing as an ATM technician, then uses a crowbar to open the top of the ATM – the “top hat” – to gain access to the personal computer that operates the machine. Once he or she has access to the PC, they remove the hard drive, disable any anti-virus software, install a malware program, replace the hard drive and then reboot the computer. The whole operation takes about 30 seconds. The malware then enables the thief to remotely control the ATM and direct it to dispense all its cash on command. If a legitimate customer approaches the machine in the meantime, it can operate as usual until activated otherwise by the malware.
