As the surveillance industry adopts network cameras, it leaves behind the legacy NTSC/PAL-based video constraints. These constraints are mostly characterized as resolution limits. This is a great thing for the security industry as a whole, because the increased level of image detail improves the speed and accuracy of investigations.
Much has been written about the significant bandwidth and storage savings H.264 provides when compared to MJPEG or MPEG4 Part 2. A related topic is the various ways H.264 can be configured and the resulting impact to image quality. Resolution, lighting, scene activity, bit rate, rate type, I-frame interval and compression all dramatically change how image quality is captured, transmitted and stored.
Many within the surveillance industry are deploying IP video surveillance cameras and networked recorders using the same design and engineering strategies used for building analog CCTV camera and DVR-based systems. On the surface this makes sense: surveillance is surveillance; the fundamental optics and geometry remains the same regardless of the medium. What isn’t the same is how the IP systems operate under day and night conditions.
Outdoor perimeter security is an often-overlooked area of physical security design that can dramatically improve the effectiveness of a facility’s security system. If you are involved in designing or managing physical security the infrastructure located in the buildings likely consumes the majority of your budget.
In today’s surveillance market we exceedingly judge ourselves by the number of megapixels of a camera. However, when trying to display all of those pixels the reality gets lost. This didn’t stop Avigilon from recently announcing plans for their 29MP camera, and it became apparent that our market is going to continue to run toward megapixel technology regardless of the practical usage.
At the 2007 IMS Analytics Conference in Amsterdam, it was forecasted that the VCA (Video Content Analytics) market would penetrate 40 percent of the security video market. This forecast obviously was prior to the great worldwide recession, however it still proves that there is such a thing as a “hype curve of growth.” This estimate was obviously higher than what has been realized over the past four years.
The Lexus came out squeaky clean. Then came the Chevy, the Buick, the Honda, and more. Autobell, founded in Charlotte, NC, in 1969 by Charles Howard, is now the biggest car wash chain in the southeast. From the beginning, Howard showcased the latest in car wash equipment technology with a focus on the environment and the community.
How well a hardware or software platform can adapt to increasing demands defines the term scalability. This term is becoming the de facto reason why the security industry has been replacing older DVRs with newer storage solutions. The popularity of video encoder devices as standalone appliances versus bundled into the DVR is accelerating this industry shift even further.
The security industry has adopted some bad habits from the IT industry. These habits are most noticeable in systems that can be described as “over built” and “under delivered.” The trend of building overly complex systems creates challenges for systems integrators, and is a huge strain on end user’s security budget. This problem exists due to a lack of knowledge and experience with the complex surveillance technologies used in today’s networked video world. The following illustrates the most common over/under design issues in surveillance systems, which continue to get worse.
In the middle of the physical security convergence industry are the open platform software providers making significant contributions toward the adoption of IP-based physical security solutions. These companies aren’t the largest in the industry, yet by providing innovative software features they meet the customer’s needs and unlock the innovation of the hardware manufacturers. Without these software features and integration services, customers would not likely adopt IP cameras over analog security video systems. This innovation is the fuel of the new physical security economy.
