Surge protection for security installations: 2017 saw increased investment
Surge protection for security installations: 2017 saw increased investment

In 2017, DITEK saw how power surges from the many natural disasters that took place damaged many businesses. In a natural disaster, or even everyday business operations, a facility’s entire investment in security, life safety and surveillance systems technology can be disabled or rendered useless in a few seconds. Surge protection solutions can mitigate those risks and protect security investments. Proactive approach to risk mitigation Throughout 2017, we also witnessed a change in how enterprises view surge protection, which included how investments are being made in surge protection to protect valuable security, life safety and surveillance systems, while also reducing downtime, manpower costs, liability vulnerabilities, and possibly compliance issues that can force businesses to actually cease operations. Effective security management is about mitigating risks. But risks cannot be mitigated without a proactive approach. Enterprises and integrators, who take the time to assess risk and to develop a strategy to incorporate effective detection, deter and response criteria to protect physical assets will be successful in 2018. 2018 and beyond That strategy includes designing surge protection into new security systems, while also adding surge protection to existing systems. Enterprises and security integrators who implement a surge protection strategy during security planning processes – or after – will be exercising prevention and mitigation, and they will be successful in 2018 and beyond.  Surge protection devices have an untapped potential for enterprise surveillance and security systems In 2017, Ditek continued to offer security end users a solid surge protection solution. We also successfully educated system integrators, who are seeking value-added products or services to incorporate into their portfolios, on the importance of surge protection devices. Educating security integrators We believe that surge protection devices have an untapped potential for enterprise video surveillance and security systems, because they can and do meet safety and security challenges that have been rarely identified in the past. We are looking forward to 2018, when we will continue to develop new surge protection products – including a new product engineered to protect up to twelve individual fuel dispensers, which is critical to the financial operation of convenience stores. We will also continue to educate security integrators about the importance of including surge protection in the design/build RFP, to not only secure an enterprise’s valuable security equipment, but also to help integrators to differentiate their capabilities and knowledge from the competition.

Extenders convert media for longer video distance runs
Extenders convert media for longer video distance runs

IP/PoE systems eliminate the need for local power, thus saving installation costs Cost considerations are an important reason to use existing installed cable as part of a new system infrastructure. Extenders in the form of media converters can help. For almost three decades, video surveillance systems existed in the form of analogue systems. Video coaxial cable was the primary method of transmission with a limited distance of about 750 feet. Analogue systems required separate power supply located at each security camera site. Today, new technology often solves one problem and creates another. Internet Protocol/Power over Ethernet (IP/PoE) systems eliminate the need for local power supply, thus saving installation costs. The drawback is the restriction to only 328 feet and the required use of Cat 5e or above cable. Extended transmission distance So tens of thousands of video surveillance cameras are waiting to be converted to IP, and have been transmitting over coax at distances two-and-a-quarter-times greater than the Ethernet limit. The advent of extenders helps to solve this problem. In addition, the use of extenders for Cat cable and even single-pair alarm wire helps to add to the types of IP/PoE conversions while extending distance as far as three thousand feet. Tens of thousands of camerasare waiting to be converted to IP,and have been transmitting overcoax at distances two-and-a-quarter-times greater than theEthernet limit Considerations while using extenders Use of extenders requires taking several considerations into account. First and most important is a careful reading of specifications. A statement can be true while not applying to your applications. Let’s take IP/PoE transmission over coax as an example. A manufacturer’s product can state it has this feature and will meet your transmission requirement of X number of thousand feet. However, a careful reading reveals that achieving this requires RG 6 cable while you have RG 59 installed. You need to maintain a 100Mbps bandwidth and provide your cable with 12.95 watts of power. But as both bandwidth and power decrease with distances obtainable from many types of extensions, you realise that both are much less at the extended distance you require. In short, just depending on a product to make a simple specification statement is not enough when it comes to infrastructure considerations and especially with regards to extenders. Save Save

Dahua thermal monitoring solutions help businesses become COVID-19 pandemic-ready and resume operations
Dahua thermal monitoring solutions help businesses become COVID-19 pandemic-ready and resume operations

Dahua Technology, the globally renowned video security and smart IoT solutions provider, is helping businesses reopen amid the COVID-19 pandemic. Thermal imaging, face detection, and other technologies play key roles in screening for skin temperature and determining whether someone is wearing a mask or not. Thermal temperature monitoring “Since the start of the COVID-19 pandemic, Dahua has been devoted to providing an array of solutions to help keep businesses running wherever possible,” remarked Jennifer Hackenburg, Senior Product Marketing Manager of Dahua Technology USA. Jennifer adds, “Our offerings reflect the varied needs of different business environments – we strive to provide options for every budget and application.” SafetyTemp Thermal Temperature Station Compact and simple, the SafetyTemp Thermal Temperature Station is ideally suited for small installations Thermal temperature monitoring lets business owners get fast, accurate readings of the skin temperature of employees and customers. People pass through a checkpoint where a monitoring station measures the temperature of their skin, while no physical contact is made and the traffic flow remains smooth. Compact and simple, the SafetyTemp Thermal Temperature Station is ideally suited for small installations. It takes measurements from up to six feet away and in only 0.2 seconds, raising audible alerts if a person’s skin temperature is above a user-defined threshold. It can also help determine whether a person is wearing a mask. Dahua Thermal Temperature Monitoring Solution For medium and large installations, the Dahua Thermal Temperature Monitoring Solution is a more robust option that incorporates a hybrid network thermal camera, an NVR, and a blackbody calibration device for highly accurate skin temperature measurements (±0.54° F). Like SafetyTemp, this is a contact-free solution that makes screening fast and efficient. As people pass through the checkpoint, their skin temperatures are captured and the system can send alerts about temperature or mask status via the 4K 16-inch 1U NVR (DHI-NVR5216-16P-I) or a mobile app (DMSS). Thermal cameras deployed Two different camera options are available, including a new model (DH-TPC-BF3221-T), which is well-suited for medium-sized businesses due to a lower price point. It offers accurate readings from up to 16 feet away. The high-end model (DH-TPC-BF5421) has a higher resolution thermal lens, lower NETD, and large aperture, resulting in more pixels and less noise in the image. This, in turn, means more data points for the system to analyse and lets the camera obtain readings from up to 23 feet away. Handheld Thermal Temperature Monitoring Device Handheld Thermal Temperature Monitoring Device, DH-TPC-HT2201 features a 3.5mm camera For a portable solution, the Handheld Thermal Temperature Monitoring Device, DH-TPC-HT2201 features a 3.5mm camera that can be aimed directly at the subject from a safe distance. AI temperature measurement facilitates high accuracy (±0.9° F), and an alarm sounds when a person’s skin temperature exceeds a user-defined threshold. This simple to use, cost effective device is best employed in small applications with a dense customer or personnel base. A built-in, rechargeable, lithium-ion battery lasts more than eight hours in between charging. Smart Motion Detection and Face Detection When mask detection is the top priority, a new 5MP dome camera (N55DY82) gives users an active alarm message when it detects people without masks within its field of view. A wealth of other features, including perimeter protection, people counting, heat mapping, Smart Motion Detection (SMD) and face detection, make this high-performing camera an excellent security solution as well. Highly accurate, it can be paired with a thermal temperature camera for a complete solution. Floor-Standing Digital Signage Dahua’s 55-inch Floor-Standing Digital Signage (DHI-LDV55-INDOOR) complements digital monitoring checkpoints. It offers a 1080p display screen that is customisable to display safety requirements, provide instructions for those preparing to have their temperature measured, or simply point people in the right direction. The digital signage can also be deployed as a component of Dahua’s new flow control solution It supports a wide range of audio and video encoding formats and has built-in media player software and a USB player for displaying advertisements. The digital signage can also be deployed as a component of Dahua’s new flow control solution. This solution helps businesses maintain social distancing protocols and avoid overcrowding while streamlining efforts and reducing manpower for facilities where occupancy is regulated. People-counting camera installed A people-counting camera installed at a restaurant entrance, for example, keeps track of how many people have entered and exited. Working in tandem, the display tells customers when they may enter the restaurant, grocery store, or retail store, or when it is at capacity and they need to wait. The entire solution can integrate with the mask detection camera and thermal temperature solutions for large applications needing to manage a complex set of safety and health requirements. “Convenience and accuracy are important to our customers as they reopen their businesses,” stated Hackenburg, adding “Dahua has risen to the challenge by providing flexible options for a variety of needs and budgets, supporting a more seamless transition into this new way of doing business.”
