Microsemi Corporation, a provider of semiconductor solutions differentiated by power, security, reliability and performance, announced its new SyncServer S80 server integrating a GPS antenna, receiver and Network Time Protocol (NTP) timing server into a single ruggedised, environmentally hardened unit ideal for outdoor installation with physical security systems. The high-reliability device, well-suited to synchronise timing for IP security cameras, Access Control Devices, Digital Video Recorders (DVR) or Network Video Recorders (NVR) or operate as the master clock for time display networks common to transportation like railways and airports, education institutions and even small enterprise networks, secures accurate time to reduce network exposure to vulnerable public time servers or external attacks such as denial of service (DoS).

Equipped with Power-over-Ethernet

The network-ready SyncServer S80 is designed for easy integration into existing physical security networks and serves as the primary source of accurate time for the essential time stamps on security video footage. Equipped with Power-over-Ethernet (PoE), the device easily connects into an existing PoE infrastructure that runs power, timing and video feed through a single cable. In the cases where Ethernet infrastructure is in place but PoE is not available, the S80 can be powered through the addition of a Microsemi single-port PoE Injector or a managed 6, 12 or 24 port PoE Midspan. Since the S80 is also ruggedised for outdoor installations, it can connect to the network right alongside an existing outdoor camera installation, with the addition of a Microsemi PDS-104GO 4+1 managed outdoor switch. Once connected to the network, the S80 is ready to be the source of authoritative NTP time stamps for all video camera recordings.

"Accurate, reliable and secure time stamps on video surveillance footage are essential to prove when a video was recorded"

“Accurate, reliable and secure time stamps on video surveillance footage are essential to prove when a video was recorded. Our legal system has shown video footage may be inadmissible as court evidence without these accurate timestamps,” said Paul Skoog, senior product manager for Microsemi. “The challenge the SyncServer S80 solves is bringing that accurate and secure time into video surveillance networks, which are often network isolated for security or practical purposes from the outside world. The S80 is also a much more accurate, secure and reliable source of time inside the network versus using time from public time servers on the open internet, which are susceptible to spoofing and DoS attacks.”

NTP Reflector technology

According to a 2017 IHS Markit Top Video Surveillance Trends for 2017 report, 98 million network surveillance cameras will be shipped globally in 2017 in a market estimated to be growing at almost 7 percent annually. Many of these cameras are destined for isolated networks, including moving platforms such as ferries, where accurate time is essential to add the trusted “when” to video recordings.

Microsemi’s new SyncServer S80 is designed to provide ultra-accurate, nanosecond caliber NTP time stamps using the company’s security-hardened NTP Reflector technology. Unlike other NTP servers often used for IP camera time stamps, Microsemi’s NTP Reflector also works as a central processing unit (CPU)-protecting firewall, shielding the S80 CPU from excessive NTP request loading, which negatively affects time stamp accuracy, reduces availability of time stamps and can leave the device susceptible to CPU freezing or system reset. The S80 is ideally suited for video networks with tens to thousands of IP cameras, with no degradation in NTP server performance while operating as the trusted source of accurate time on the network.

How artificial intelligence (AI) is changing video surveillance today
How artificial intelligence (AI) is changing video surveillance today

There’s a lot of excitement around artificial intelligence (AI) today – and rightly so. AI is shifting the modern landscape of security and surveillance and dramatically changing the way users interact with their security systems. But with all the talk of AI’s potential, you might be wondering: what problems does AI help solve today? The need for AI The fact is, today there are too many cameras and too much recorded video for security operators to keep pace with. On top of that, people have short attention spans. AI is a technology that doesn’t get bored and can analyse more video data than humans ever possibly could.AI is a technology that doesn’t get bored and can analyse more video data than humans ever possibly could It is designed to bring the most important events and insight to users’ attention, freeing them to do what they do best: make critical decisions. There are two areas where AI can have a significant impact on video surveillance today: search and focus of attention. Faster search Imagine using the internet today without a search engine. You would have to search through one webpage at a time, combing through all its contents, line-by-line, to hopefully find what you’re looking for. That is what most video surveillance search is like today: security operators scan hours of video from one camera at a time in the hope that they’ll find the critical event they need to investigate further. That’s where artificial intelligence comes in. The ability of AI to reduce hours of work to mere minutes is especially significant when we think about the gradual decline in human attention spans With AI, companies such as Avigilon are developing technologies that are designed to make video search as easy as searching the internet. Tools like Avigilon Appearance Search™ technology – a sophisticated deep learning AI video search engine – help operators quickly locate a specific person or vehicle of interest across all cameras within a site. When a security operator is provided with physical descriptions of a person involved in an event, this technology allows them to initiate a search by simply selecting certain descriptors, such as gender or clothing colour. During critical investigations, such as in the case of a missing or suspicious person, this technology is particularly helpful as it can use those descriptions to search for a person and, within seconds, find them across an entire site. Focused attention           The ability of AI to reduce hours of work to mere minutes is especially significant when we think about the gradual decline in human attention spans. Consider all the information a person is presented with on a given day. They don’t necessarily pay attention to everything because most of that information is irrelevant. Instead, they prioritise what is and is not important, often focusing only on information or events that are surprising or unusual. Security operators scan hours of video from one camera at a time in the hope that they’ll find the critical event they need to investigate further Now, consider how much information a security operator who watches tens, if not hundreds or thousands of surveillance cameras, is presented with daily. After just twenty minutes, their attention span significantly decreases, meaning most of that video is never watched and critical information may go undetected. By taking over the task of "watching" security video, AI technology can help focus operators’ attention on events that may need further investigation. As AI technology evolves, the rich metadata captured in surveillance video will add even more relevance to what operators are seeing For instance, technology like Avigilon™ Unusual Motion (UMD) uses AI to continuously learn what typical activity in a scene looks like and then detect and flag unusual events, adding a new level of automation to surveillance. This helps save time during an investigation by allowing operators to quickly search through large amounts of recorded video faster, automatically focusing their attention on the atypical events that may need further investigation, enabling them to more effectively answer the critical questions of who, what, where and when. As AI technology evolves, the rich metadata captured in surveillance video – like clothing colour, age or gender – will add even more relevance to what operators are seeing. This means that in addition to detecting unusual activities based on motion, this technology has the potential to guide operators’ attention to other “unusual” data that will help them more accurately verify and respond to a security event. The key to advanced security When integrated throughout a security system, AI technology has the potential to dramatically change security operations There’s no denying it, the role of AI in security today is transformative. AI-powered video management software is helping to reduce the amount of time spent on surveillance, making security operators more efficient and effective at their jobs. By removing the need to constantly watch video screens and automating the “detection” function of surveillance, AI technology allows operators to focus on what they do best: verifying and acting on critical events. This not only expedites forensic investigations but enables real-time event response, as well. When integrated throughout a security system, AI technology has the potential to dramatically change security operations. Just as high-definition imaging has become a quintessential feature of today’s surveillance cameras, the tremendous value of AI technology has positioned it as a core component of security systems today, and in the future.

What are the obstacles to adoption of mobile credentials for access control?
What are the obstacles to adoption of mobile credentials for access control?

Using a smart phone as an access control credential is an idea whose time has come – or has it? The flexible uses of smart phones are transforming our lives in multiple ways, and the devices are replacing everything from our alarm clocks to our wallets to our televisions. However, the transformation from using a card to using a mobile credential for access control is far from a no-brainer for many organisations, which obstacles to a fast or easy transition. We asked this week’s Expert Panel Roundtable: When will mobile credentials dominate access control, and what are the obstacles to greater adoption?

How to choose the right security entrance for effective customer security
How to choose the right security entrance for effective customer security

Security and systems integrators across the nation are recommending and providing long-term security solutions to their customers. But when it comes to physical security entrances, integrators can easily fall into the trap of simply fulfilling an end user’s exact request without much pushback. Why? We believe the complexity and variety of entrances available makes it difficult to consult on the best solution, but also because there are a lot of assumptions at play. 1) Ask questions to determine the correct security entrance solution There is confusion in the security industry on the meaning of the word, “turnstile.” End users, when requesting a solution, tend to use the word “turnstile” to describe anything from an old fashioned, 3-arm turnstile to a high-tech optical turnstile to a security revolving door. We encourage security integrators to ask questions to discover how their clients want to mitigate the risk of unauthorised entry or “tailgating.” This can help determine the correct security entrance solution to meet the end user’s goal and budget. By asking the right questions and offering true solutions, you can enhance a relationship built on trust and consultation leading to potential repeat business. Below are four physical security goals—crowd, deterrence, detection, and prevention—accompanied by the type of “turnstile” and its capabilities. This breakdown can help the integrator to confidently address an end user’s request for a “turnstile,” and then recommend a solution that truly fulfills their security goals. 2) Explore options for crowd control Typically seen in stadiums, amusement parks, universities, and fitness centres, tripod turnstiles are considered a low security solution for crowd management. Designed for counting employees or slowing down high traffic volume to collect tickets or payments, tripod turnstiles are built to withstand the most abusive of conditions. Here’s what security integrators should know about tripod turnstiles: Low capital cost, but high annual operating cost due to needed 24/7 guard supervision Lack of sensors can lead to defeat – turnstiles can be crawled under or jumped over without alarm/notification to guard staff Little to no metrics capabilities available – no sensors or alarms if defeated High throughput, handling 30 persons per minute in one direction Full height turnstiles are a tall, robust solution for perimeter fence lines, metro stations or parking garages 3) Choose an effective deterrent A physical deterrent to infiltration, full height turnstiles are a tall, robust solution for perimeter fence lines, metro stations or parking garages. While full height turnstiles do physically stop tailgating (an unauthorised person following someone in the next compartment), they have no means to prevent piggybacking. Two people in collusion can gain access through the full height turnstile by badging once and then squeezing into the same compartment. Here are some other things to note about full height turnstiles: Low capital cost, low annual operating cost Guard supervision is up to the user Little to no metrics capabilities available – no sensors or alarms if defeated Moderate throughput, handling 18 persons per minute in one direction 4) Ensure your chosen turnstile can detect tailgating A staple in lobby security to accommodate visitors, optical turnstiles utilise complex sensors to detect a tailgating attempt. Most models available today offer sliding or swinging barriers. A very common assumption in the security industry is that optical turnstiles prevent unauthorised entry, which isn’t true. In fact, once the barriers are open, a second user can slip through. Or, in the case of a wide lane for disabled use, two people can walk through side by side. In either case, an alarm is generated and supervision is therefore essential in order to respond swiftly. The cost of 24/7 supervision must be factored into the security budget. Here are some other points to make note of: Moderate capital cost, but high annual operating cost due to need for 24/7 guard supervision Sensors detect tailgating and sound an alarm for post-tailgating reaction, but turnstiles can still be defeated Moderate metrics capabilities available (for example, # times tailgating occurred, passback rejection) High throughput, handling up to 30 persons per minute in one direction 5) Determine prevention tactics for staff and visitor safety The entry solution of choice for Fortune 1000 companies, security revolving doors and mantrap portals completely prevent tailgating due to their working principle, ensuring the safety and security of staff and visitors. Commonly used at employee-only entrances, security doors are an unmanned entrance solution that cannot be defeated; sensors in the ceiling prevent tailgating (following in a trailing compartment). Optional piggybacking detection systems are also available (preventing two people in the same compartment from entering). The benefits of utilising a truly unmanned door are unparalleled: guard staff can be reduced or reallocated, and this entrance offers an ROI of just 1-2 years. Here’s more information security integrators should know about security revolving doors and portals: High capital cost, low annual operating cost due to no required guard supervision Sophisticated metrics capabilities available, allowing the end user to prove the value of their security investment Security revolving doors = 20 persons per minute, simultaneously in two directions; Security portals = 6 persons per minute in one direction Biometric devices and bullet-resistant glass can be incorporated for an even higher level of security As we’ve demonstrated here, “turnstile,” in the eyes of an end user, is a complex term that can range from a low security, crowd control solution to a high security, tailgating prevention entrance. Security integrators need to first accurately determine the security goals of their customers and then break down the “turnstile” barrier of confusion to recommend the best solution for fulfilling those goals.
