Everybody has been hooked on the discussions about Analogue HD or IP systems, but shouldn’t we really be thinking about WiFi and 5G connectivity, removing the need for expensive cabling? Are wireless networks secure enough? What is the potential range? Even the basic question about whether or not the network is capable of transferring the huge (and growing) amount of data required for High Res Video, which will soon be quadrupled with the advent of 4K and higher resolutions.

The future of video surveillance monitors

We have seen a massive uptake in 4K monitors in the security industry. While they have been relatively common in the consumer market, they are only now beginning to really take off in the CCTV market, and the advances in Analogue HD and IP technology mean that 4K is no longer the limited application technology it was just a few years ago.

Relatively easy and inexpensive access to huge amounts of storage space, either on physical storage servers or in the cloud, both of which have their own positives and negatives, have really helped with the adoption of 4K. Having said that the consensus seems to be, at least where displays are concerned, there is very little need for any higher resolution. So, where next for monitors in CCTV?

8K monitors are present, but are currently prohibitively expensive, and content is in short supply (although the Japanese want to broadcast the Tokyo Olympics in 8K in 2020). Do we really need 8K and higher displays in the security industry? In my own opinion, not for anything smaller than 100-150+ inches, as the pictures displayed on a 4K resolution monitor are photo realistic without pixilation on anything I’ve seen in that range of sizes.

displays are concerned, there is very little
need for any higher resolution

Yes, users many want ultra-high resolution video recording in order to capture every minute detail, but I feel there is absolutely no practical application for anything more than 4K displays below around 120”, just as I feel there is no practical application for 4K resolution below 24”. The higher resolution camera images can be zoomed in and viewed perfectly well on FHD and 4K monitors. That means there has to be development in other areas.

Developments in WiFi and 5G

What we have started to see entering the market are Analogue HD and IP RJ45 native input monitors. Whilst you would be forgiven for thinking they are very similar, there are in fact some huge differences. The IP monitors are essentially like All-In-One Android based computers, capable of running various versions of popular VMS software and some with the option to save to onboard memory or external drives and memory cards. These are becoming very popular with new smaller (8-16 camera) IP installs as they basically remove the need for an NVR or dedicated storage server.

Developments in the area of WiFi and 5G connectivity are showing great promise of being capable of transferring the amount of data generated meaning the next step in this market would maybe be to incorporate wireless connectivity in the IP monitor and camera setup. This brings its own issues with data security and network reliability, but for small retail or commercial systems where the data isn’t sensitive it represents a very viable option, doing away with both expensive installation of cabling and the need for an NVR.

Larger systems would in all likelihood be unable to cope with the sheer amount of data required to be transmitted over the network, and the limited range of current wireless technologies would be incompatible with the scale of such installs, so hard wiring will still be the best option for these for the foreseeable future.

VR on the other hand is fully immersive, and for playback or monitoring of camera feeds would provide a great solution
There will be a decline in the physical display market as more development goes into Augmented and Virtual Reality

Analogue HD options

Analogue HD options have come a long way in a quite short time, with the latest developments able to support over 4MP (2K resolution), and 4K almost here. This has meant that for older legacy installations the systems can be upgraded with newer AHD/TVI/CVI cameras and monitors while using existing cabling. The main benefit of the monitors with native AHD/TVI/CVI loopthrough connections is their ability to work as a spot monitor a long distance from the DVR/NVR. While co-axial systems seem to be gradually reducing in number there will still be older systems in place that want to take advantage of the benefits of co-axial technology, including network security and transmission range. Analogue technologies will eventually become obsolete, but there is still much to recommend them for the next few years.

Another more niche development is the D2IP monitor, which instead of having IP input has HDMI input and IP output, sending all activity on the screen to the NVR. This is mainly a defence against corporate espionage, fraud and other sensitive actions. While this has limited application those who do need it find it a very useful technology, but it’s very unlikely to become mainstream in the near future.

Augmented Reality and Virtual Reality

Does the monitor industry as a whole have a future? In the longer term (decades rather than years) there will definitely be a decline in the physical display market as more and more development goes into AR (Augmented Reality or Mixed Reality depending on who’s definition you want to take) and VR (Virtual Reality).

Currently AR is limited to devices such as smartphones (think Pokémon Go) and eyewear, such as the ill-fated Google Glass, but in the future, I think we’ll all have optical implants (who doesn’t want to be The Terminator or RoboCop?), allowing us to see whatever we decide we want to as an overlay on the world around us, like a high-tech HUD (Heads Up Display). VR on the other hand is fully immersive, and for playback or monitoring of camera feeds would provide a great solution, but lacks the ability to be truly useful in the outside world the way that AR could be.

Something not directly related to the monitor industry, but which has a huge effect on the entire security industry is also the one thing I feel a lot of us have been oblivious to is the introduction of quantum computers, which we really need to get our heads around in the medium to long term. Most current encryption technology will be rendered useless overnight when quantum computers become more widespread.

So, where does that leave us? Who will be the most vulnerable? What can we do now to mitigate the potential upheaval? All I can say for sure is that smarter people than me need to be working on that, alongside the development of the quantum computer itself.

Newer methods of encryption are going to be needed to deal with the massive jump in processing power that comes with quantum. I’m not saying it will happen this year, but it is definitely on the way and something to be planned for.

2018 FIFA World Cup Russia integrates safety, security and service
2018 FIFA World Cup Russia integrates safety, security and service

The 2018 FIFA World Cup tournament is bringing 32 national teams and more than 400,000 foreign football fans from all over the world to 12 venues in 11 cities in Russia. Fans are crowding into cities including Moscow, St. Petersburg and Kazan. Given continuing global concerns about terrorism, security is top-of-mind. Protection of the World Cup games in Russia is focusing on an “integrated safety, security and service approach,” according to officials. Combining the term “security” with the terms “safety” and “service” is not an accident. An aggressive security stance is necessary, but at the end of the day, fan safety is paramount, and a service-oriented approach ensures a positive fan experience. Medical responders will be working side-by-side with police and antiterrorism personnel. Risk management best practices We asked Sean T. Horner and Ben Joelson, directors of the Chertoff Group, a global advisory firm focused on best practices in security and risk management, to comment on security at FIFA World Cup 2018. Although not involved in securing the 2018 World Cup, the Chertoff Group is experienced at securing large events and enterprises using risk management, business practices and security. Integration is another important aspect of protecting the games, says Horner. The use of multiple resources, including Russian military, intelligence and law enforcement, will be closely integrated to provide the best security for the large-scale event in each of the host cities, he says. The approach will be centralised and flexible, with resource deployment guided by effective situational awareness. Primary security and emergency operations centres will be dispersed throughout each host city “There is a unified command structure at the Russian Federation level, and they will keep resources in reserve and shift them as needed to various events and venues based on any specific intelligence, in effect deploying resources where threats are greatest,” says Joelson. “There will also be some regional commands, and resources will incorporate a spectrum of police and military personnel ranging from the ‘cop on the beat’ to the Spetsnaz, the Russian ‘special forces'.” Primary security and emergency operations centres will be dispersed throughout each host city, and additional forces can be shifted as necessary, he notes. Role of law enforcement In Russia, the lines of separation between law enforcement and the military are not as stark as in the United States, for example, where military forces are restricted from deployment for domestic law enforcement by the Posse Comitatus Act. In Russia, there is no such restriction.  A broad range of technology will play a role at the World Cup, Horner and Joelson agree. Technology will be used primarily as a force multiplier and a decision-support tool for security personnel. There are robust CCTV systems in many Russian cities, and mobile CCTV systems, such as camera towers or mobile security centres on wheels, will also be deployed. Technologies will include infrared cameras, flood lights, and ferromagnetic screening systems to scan hundreds of individuals as they walk by. In some locations, facial recognition systems will be used, tied into various intelligence, military and law enforcement databases of known bad actors. Behaviour analytics will be used as a decision-support tool. In addition to security in public areas, private CCTV systems in hotels, at transportation hubs, and inside the venues themselves will be leveraged. Video analytics and detection will help personnel review live view of people who may be acting suspiciously or who leave a bag unattended. In some locations, facial recognition systems will be used, tied into various intelligence, military and law enforcement databases of known bad actors Rigorous anti-terrorism measures A Fan ID card is required to enter the 2018 World Cup Tournament, even for Russian residents. The Russians have an aggressive stance against domestic terrorism, which will also help ensure the safety of the World Cup games, say Horner and Joelson. Terrorist group ISIS has promised “unprecedented violence” at the games, but they make similar threats at every major global event. Russia has been an active force disrupting ISIS in Syria, and experts suggest that losing ground geographically could lead to addition “asymmetric” terrorist attacks. However, Russia is leveraging all their intelligence resources to identify any plots and deploying their security apparatus to disrupt any planned attacks, experts say. Russia’s rigorous anti-terrorism measures include a total ban on planes and other flying devices (such as drones) around the stadiums hosting the World Cup. Private security In addition to military, intelligence and law enforcement personnel, private security will play a have a high profile during the 2018 World Cup in Russia. Private security personnel will be on the front lines in hotels and in “fan zones.” They will operate magnetometers at entrances, perform bag checks, enforce restrictions on hand-carried items, etc. Private security will be especially important to the “guest experience” aspects of protecting the games. Private security will be especially important to the “guest experience” aspects of protecting the games Another private security function at the World Cup is executive protection of dignitaries and high-net-worth individuals who will be attending. Executive protection professionals will arrive early, conduct advanced security assessments before VIPs arrive, and secure trusted and vetted transportation (including armoured cars in some cases.) VIPs will include both Russian citizens and foreign (including U.S.) dignitaries attending the games. Private security details will be out in force. Aggressive security approach Overeager and outspoken fans are a part of the football culture, but Russia will deploy a near-zero tolerance policy against hooliganism and riots. An overwhelming force presence will take an aggressive approach to curbing any civil disturbances, and offenders will be removed quickly by Russian security forces. Strict restrictions on the sale and consumption of alcohol will be enforced in the venue cities before and after the matches. Officials will also be cognisant of the possibility of a riot or other event being used as a distraction to draw attention from another area where a terrorist event is planned. It will be a delicate balance between deploying an aggressive security approach and preserving the fan experience. Joelson notes that freedom of speech is not as valued in Russia as in other parts of the world, so the scales will be even more tipped toward security. “The last thing they want is for things to get out of control,” says Horner. “The event is putting Russia on the world stage, and they want visitors to walk away safely after having a great time and wanting to go back in the future.” Attendees should also have good situational awareness, and keep their heads up, scanning crowds and identifying unsafe situations" Precautions for World Cup attendees Attendees to the World Cup in Russia should take some basic precautions, Horner and Joelson agree. For example, Russia requires a translated, notarised letter explaining any prescription drugs. The country has a more aggressive foreign intelligence environment, so visitors cannot depend on their data being private. Joelson recommends the usual “social media hygiene” and privacy settings. Visitors should not post information about their travel plans or locations, and it’s best to travel with a disposable mobile phone that does not contain personal information. Location tracking should be deactivated. Travellers should also beware of talking and sharing information with others, or of saying anything derogatory. “They should also have good situational awareness, and keep their heads up, scanning crowds and identifying unsafe situations,” says Joelson. “If you bring a personal electronic device, you should expect that it has been compromised,” says Horner. Text messages and email will not be private, and he suggests creating an email address used only for travel. Don’t leave drinks unattended. Travellers from the U.S. should register at the Smart Traveler Enrollment Program (STEP) operated by the U.S. State Department. “Plan before you travel and before you get to the airport,” says Horner.

The benefits and challenges of in-camera audio analytics for surveillance solutions
The benefits and challenges of in-camera audio analytics for surveillance solutions

Audio is often overlooked in the security and video surveillance industry. There are some intercom installations where audio plays a key role, but it’s not typically thought about when it comes to security and event management. Audio takes a back seat in many security systems because audio captured from a surveillance camera can have a different impact on the privacy of those being monitored. Audio surveillance is therefore subject to strict laws that vary from state to state. Many states require a clearly posted sign indicating audio recording is taking place in an area before a person enters. Analytic information derived from audio can be a useful tool and when implemented correctly, removes any concerns over privacy or legal compliance. Audio analytics on the edge overcomes legal challenges as it never passes audio outside of the camera Focused responses to events Audio analytics processed in the camera, has been a niche and specialised area for many installers and end users. This could be due to state laws governing audio recording, however, audio analytics on the edge overcomes legal challenges as it never passes audio outside of the camera Processing audio analytics in-camera provides excellent privacy since audio data is analysed internally with a set of algorithms that only compare and assess the audio content. Processing audio analytics on the edge also reduces latency compared with any system that needs to send the raw audio to an on-premises or cloud server for analysis. Audio analytics can quickly pinpoint zones that security staff should focus on, which can dramatically shorten response times to incidents. Audio-derived data also provides a secondary layer of verification that an event is taking place which can help prioritise responses from police and emergency personnel. Having a SoC allows a manufacturer to reserve space for specialised features, and for audio analytics, a database of reference sounds is needed for comparison Microphones and algorithms Many IP-based cameras have small microphones embedded in the housing while some have a jack for connecting external microphones to the camera. Microphones on indoor cameras work well since the housing allows for a small hole to permit sound waves to reach the microphone. Outdoor cameras that are IP66 certified against water and dust ingress will typically have less sensitivity since the microphone is not exposed. In cases like these, an outdoor microphone, strategically placed, can significantly improve outdoor analytic accuracy. There are several companies that make excellent directional microphones for outdoor use, some of which can also combat wind noise. Any high-quality external microphone should easily outperform a camera’s internal microphone in terms of analytic accuracy, so it is worth considering in areas where audio information gathering is deemed most important. In-built audio-video analytics Surveillance cameras with a dedicated SoC (System on Chip) have become available in recent years with in-built video and audio analytics that can detect and classify audio events and send alerts to staff and emergency for sounds such as gunshots, screams, glass breaks and explosions. Having a SoC allows a manufacturer to reserve space for specialised features. For audio analytics, a database of reference sounds is needed for comparison. The camera extracts the characteristics of the audio source collected using the camera's internal or externally connected microphone and calculates its likelihood based on the pre-defined database. If a match is found for a known sound, e.g., gunshot, explosion, glass break, or scream, an event is triggered, and the message is passed to the VMS. If a match is found for a known sound, e.g., gunshot, explosion, glass break, or scream, an event is triggered, and the message is passed to the VMS Configuring a camera for audio analytics Audio detectionThe first job of a well-configured camera or camera/mic pair is to detect sounds of interest while rejecting ancillary sounds and noise below a preset threshold. Each camera must be custom configured for its particular environment to detect audio levels which exceed a user-defined level. Since audio levels are typically greater in abnormal situations, any audio levels exceeding the baseline set levels are detected as being a potential security event. Operators can be notified of any abnormal situations via event signals allowing the operator to take suitable measures. Finding a baseline of background noise and setting an appropriate threshold level is the first step. Installers should be able to enable or disable the noise reduction function and view the results to validate the optimum configuration during setup Noise reductionA simple threshold level may not be adequate enough to reduce false alarms depending on the environment where a camera or microphone is installed. Noise reduction is a feature on cameras that can reduce background noise greater than 55dB-65dB for increased detection accuracy. Installers should be able to enable or disable the noise reduction function and view the results to validate the optimum configuration during setup. With noise reduction enabled, the system analyses the attenuated audio source. As such, the audio source classification performance may be hindered or generate errors, so it is important to use noise reduction technology sparingly. Audio source classificationIt’s important to supply the analytic algorithm with a good audio level and a high signal-to-noise ratio to reduce the chance of generating false alarms under normal circumstances. Installers should experiment with ideal placement for both video as well as audio. While a ceiling corner might seem an ideal location for a camera, it might also cause background audio noise to be artificially amplified. Many cameras provide a graph which visualises audio source levels to allow for the intuitive checking of noise cancellation and detection levels. Analytics take privacy concerns out of the equation and allow installers and end users to use camera audio responsibly Messages and eventsIt’s important to choose a VMS that has correctly integrated the camera’s API (application programming interface) in order to receive comprehensive audio analytic events that include the classification ID (explosion, glass break, gunshot, scream). A standard VMS that only supports generic alarms, may not be able to resolve all of the information. More advanced VMS solutions can identify different messages from the camera. Well configured audio analytics can deliver critical information about a security event, accelerating response times and providing timely details beyond video-only surveillance. Analytics take privacy concerns out of the equation and allow installers and end users to use camera audio responsibly. Hanwha Techwin's audio source classification technology, available in its X Series cameras, features three customisable settings for category, noise cancellation and detection level for optimum performance in a variety of installation environments.

How important is packaging in the commercial security market?
How important is packaging in the commercial security market?

High-quality products are the building blocks of successful physical security systems. How they are packaged may sometimes be seen as an unimportant detail or an afterthought. But should it be? Effective packaging can serve many functions, from creating a favorable customer impression to ensuring the product isn’t damaged in transit. Packaging can also contribute to ease of installation. On the negative side, excess packaging can be an environmental concern, especially for customers who are sensitive to green factors or to minimising waste. We asked this week’s Expert Panel Roundtable: Is packaging of products important in the commercial security market? Why or why not?
