SourceSecurity.com’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 centred 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 SourceSecurity.com, 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 panellists named below). 1. What are the limitations on where video cameras can be placed because of privacy? "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?”  "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? "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?  "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? "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? "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? "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?  "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? "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?  "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]   See the full coverage of 2015/2016 Review and Forecast articles here
