’s Expert Panel had a lot to say in 2015 on a variety of topics in our Roundtable discussions.


Not surprisingly, the discussion topics that have generated the most interest (in terms of how much visitor traffic they generated) are the same hot topics we hear about every day in the industry.

Our very most-clicked-on Roundtable discussion in 2015 was about the impact of video on privacy rights. Other hot topics that made the Top-10 list of Roundtable discussions included the Cloud (twice!), the impact of IT on physical security, and the outlook for 4K cameras.

Additional well-read discussions centered on expanding the benefits of security to other departments and how to improve training. Readers also gravitated to Expert Panel Roundtable discussions of more technical topics such as the value of full-frame-rate video and the effectiveness of panoramic view cameras (compared to pan-tilt-zoom functionality).

Rounding out the Top 10 is a discussion of the desirability (and legal implications) of using dummy cameras.

Here is a listing of the Top 10 Expert Panel Roundtable discussions posted in 2015 at, along with a “sound bite” from each discussion, and links back to the full articles.

Thanks to everyone who contributed to Expert Panel Roundtable in 2015 (including the quotable panelists named below).

1. What Are The Limitations On Where Video Cameras Can Be Placed Because Of Privacy?

Privacy rights violation in video surveillance

"Use of cameras in retail applications can easily be justified in general surveillance of sales floors and shopping aisles, but cameras should only be used in changing areas to address a particularly serious problem that cannot be addressed by less intrusive means.” [Mark Pritchard]

2. Are Cloud-Based Security Systems “Safe?”

Are cloud-based security systems “safe?”

"If the authentication principles are insufficient and weak passwords are allowed, it doesn’t matter how strong the encryption is. Because cloud-based systems are exposed to the Internet, they demand strong authentication and increased operational procedures." [Per Björkdahl]

3. How Does IT Affect The Physical Security Buying Decision?

How does IT affect the physical security buying decision?

"Of course, we all want good value, but we must invest as necessary. If you strip everything back, the integrator's job is to deliver data. If IT and security departments can keep this objective in mind, then 'value' redefines itself." [Larry Lummis]

4. Which Non-Security Uses Of Video Are Catching On? 

Video benefits beyond security

"While video can help with quality control across the supply chain, it will be especially useful in ensuring compliance with the international adulteration rule [for food manufacturers], the rule with the last court-ordered deadline on May 31, 2016." [Don Hsieh]

5. What Is The Value Of "Full-Frame-Rate" Video?

What is the value of

"I once took a client’s footage of a genuine street fight to check how many images per second were needed to prove who punched who – 25fps was fine but 12fps made the video evidence doubtful. Don’t forget, however many fps you choose, your shutter speed must be fast enough to prevent motion blur spoiling the details." [Simon Lambert]


6. When Is It Desirable To Use 'Dummy' Cameras As A Deterrent?

When is it desirable to use “dummy” cameras as a deterrent?

"If cameras are present, there is a reasonable expectation of a secure environment in both public and private areas. If the public sees cameras and assumes they are real, they could argue that they were reliant on the protection provided by the cameras." [Dave Poulin]


7. Are Megapixel Or Panoramic-View Cameras An Effective Substitute For PTZs?

Are megapixel/panoramic-view cameras an effective substitute for PTZs?

"Panoramic cameras are usually static, so zooming into a scene’s details is done in software and limited by pixels in the sensor, lens quality and software such as de-warping, so clarity at the boundaries might disappoint. PTZ cameras zoom optically, magnifying long-range details significantly better." [Simon Lambert]


8. Is HD Still The Standard Of Resolution In The Market? For How Much Longer? 

4K or HD - the standard of video resolution in the security industry

"The 720p and 1080p HDTV remains dominant today and is expected to be for the foreseeable future. The next standards-based resolution will be 4K, which represents 8.3 megapixel, but first the industry will need to improve on bandwidth with better compression and better light sensitivity." [Fredrik Nilsson]


9. What Are The Current Limitations Of Cloud-Based Systems?

What are the current limitations of cloud-based systems?

"The only remaining limitations of cloud-based systems are bandwidth and connectivity to the cloud. There is more than enough bandwidth for applications like Access Control and Visitor Management, but it will take a couple more years before all high-resolution video is cloud-based.” [Paul Bodell]


10. How Can Security Training Be Improved Among Integrators And End Users?

Security training: How to improve among integrators and end users

"Training should be sticky and persistent. Follow-up training such as on-line review and updated course material should be available to keep the knowledge fresh. Technology is constantly changing, as soon as training is complete the knowledge begins to go stale." [Charlie Erickson]

What Is The Impact Of Remote Working On Security?
What Is The Impact Of Remote Working On Security?

During the coronavirus lockdown, employees worked from home in record numbers. But the growing trend came with a new set of security challenges. We asked this week’s Expert Panel Roundtable: What is the impact of the transition to remote working/home offices on the security market?

Water Plant Attack Emphasizes Cyber’s Impact On Physical Security
Water Plant Attack Emphasizes Cyber’s Impact On Physical Security

At an Oldsmar, Fla., water treatment facility on Feb. 5, an operator watched a computer screen as someone remotely accessed the system monitoring the water supply and increased the amount of sodium hydroxide from 100 parts per million to 11,100 parts per million. The chemical, also known as lye, is used in small concentrations to control acidity in the water. In larger concentrations, the compound is poisonous – the same corrosive chemical used to eat away at clogged drains. The impact of cybersecurity attacks The incident is the latest example of how cybersecurity attacks can translate into real-world, physical security consequences – even deadly ones.Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. The computer system was set up to allow remote access only to authorized users. The source of the unauthorized access is unknown. However, the attacker was only in the system for 3 to 5 minutes, and an operator corrected the concentration back to 100 parts per million soon after. It would have taken a day or more for contaminated water to enter the system. In the end, the city’s water supply was not affected. There were other safeguards in place that would have prevented contaminated water from entering the city’s water supply, which serves around 15,000 residents. The remote access used for the attack was disabled pending an investigation by the FBI, Secret Service and Pinellas County Sheriff’s Office. On Feb. 2, a compilation of breached usernames and passwords, known as COMB for “Compilation of Many Breaches,” was leaked online. COMB contains 3.2 billion unique email/password pairs. It was later discovered that the breach included the credentials for the Oldsmar water plant. Water plant attacks feared for years Cybersecurity attacks on small municipal water systems have been a concern among security professionals for years. Florida’s Sen. Marco Rubio tweeted that the attempt to poison the water supply should be treated as a “matter of national security.” “The incident at the Oldsmar water treatment plant is a reminder that our nation’s critical infrastructure is continually at risk; not only from nation-state attackers, but also from malicious actors with unknown motives and goals,” comments Mieng Lim, VP of Product Management at Digital Defense Inc., a provider of vulnerability management and threat assessment solutions.The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online “Our dependency on critical infrastructure – power grids, utilities, water supplies, communications, financial services, emergency services, etc. – on a daily basis emphasizes the need to ensure the systems are defended against any adversary,” Mieng Lim adds. “Proactive security measures are crucial to safeguard critical infrastructure systems when perimeter defenses have been compromised or circumvented. We have to get back to the basics – re-evaluate and rebuild security protections from the ground up.” "This event reinforces the increasing need to authenticate not only users, but the devices and machine identities that are authorized to connect to an organization's network,” adds Chris Hickman, Chief Security Officer at digital identity security vendor Keyfactor. “If your only line of protection is user authentication, it will be compromised. It's not necessarily about who connects to the system, but what that user can access once they're inside. "If the network could have authenticated the validity of the device connecting to the network, the connection would have failed because hackers rarely have possession of authorized devices. This and other cases of hijacked user credentials can be limited or mitigated if devices are issued strong, crypto-derived, unique credentials like a digital certificate. In this case, it looks like the network had trust in the user credential but not in the validity of the device itself. Unfortunately, this kind of scenario is what can happen when zero trust is your end state, not your beginning point." “The attack on Oldsmar’s water treatment system shows how critical national infrastructure is increasingly becoming a target for hackers as organizations bring systems online for the first time as part of digital transformation projects,” says Gareth Williams, Vice President - Secure Communications & Information Systems, Thales UK. “While the move towards greater automation and connected switches and control systems brings unprecedented opportunities, it is not without risk, as anything that is brought online immediately becomes a target to be hacked.” Operational technology to mitigate attacks Williams advises organizations to approach Operational Technology as its own entity and put in place procedures that mitigate against the impact of an attack that could ultimately cost lives. This means understanding what is connected, who has access to it and what else might be at risk should that system be compromised, he says. “Once that is established, they can secure access through protocols like access management and fail-safe systems.”  “The cyberattack against the water supply in Oldsmar should come as a wakeup call,” says Saryu Nayyar, CEO, Gurucul.  “Cybersecurity professionals have been talking about infrastructure vulnerabilities for years, detailing the potential for attacks like this, and this is a near perfect example of what we have been warning about,” she says.  Although this attack was not successful, there is little doubt a skilled attacker could execute a similar infrastructure attack with more destructive results, says Nayyar. Organizations tasked with operating and protecting critical public infrastructure must assume the worst and take more serious measures to protect their environments, she advises. Fortunately, there were backup systems in place in Oldsmar. What could have been a tragedy instead became a cautionary tale. Both physical security and cybersecurity professionals should pay attention.

How Have Security Solutions Failed Our Schools?
How Have Security Solutions Failed Our Schools?

School shootings are a high-profile reminder of the need for the highest levels of security at our schools and education facilities. Increasingly, a remedy to boost the security at schools is to use more technology. However, no technology is a panacea, and ongoing violence and other threats at our schools suggest some level of failure. We asked this week’s Expert Panel Roundtable: How have security solutions failed our schools and what is the solution?
