PTZ cameras - Expert commentary

Video surveillance technology continues to evolve at a strong pace with improvements in resolution, integration, intelligence and bandwidth utilisation – all of which contribute to better overall security and cost-efficiency. As the video surveillance category continues to grow, we spoke with Jeff Whitney, Arecont Vision’s Vice President of Marketing, about some of the factors driving the market.   Maturity of integrated systems There continues to be a great deal...

The security industry’s continued migration to networked IP-based systems ensures that PoE will be integral in their design and installation Power over Ethernet (PoE) has without question become the de facto choice of security installers for delivering power to security and access control devices. This should come as no surprise given PoE’s ability to reduce labour and installation costs by delivering power and data over a single cable, thereby increasing overall t...

A 360-degree technology solution can be installed across the gaming floor, integrated right into the VMS and used for forensic purposes New 360-degree cameras are providing new video surveillance benefits to the casino market. MGM Resorts International has rolled out Oncam’s 360-degree technology solutions to the Aria, MGM Grand, Bellagio, Mirage and New York-New York properties along the Las Vegas strip. More specifically, the surveillance team at the Aria manages more...

Michael Byrden, Sales Director of ACT, considers the convergence of facility management. He describes how ACT, the access control manufacturer, has acquired a VMS and analytics development house in order to unify security solutions and bring customers nearer to the goal of a truly intelligent building. Desire for open systems Major acquisitions have been dominating the news recently and, even if this lays me open to a charge of naivety, I genuinely believe that they aren’t predatory. As...

Just as with network switches, there are no real standards for midspans In general terms, a midspan is a power over Ethernet (PoE) power source that is placed between a network switch and the device being powered, hence the term midspan. The real question is, with almost all network switches providing PoE power, why do we need a midspan? The answer is, in some cases we don’t, but in others we do. As with any other product we have discussed, we need to first consider that...

Too often a valid assumption turns out to be the opposite in practical operation It’s easy to misinterpret product specifications of IP video transmission products to the detriment of system functionality. We have seen how this problem relates to port speed, power over Ethernet (PoE) and transmission media. Now let’s look at some additional aspects of product specifications – and how they can be misinterpreted. Importance Of Temperature Rating What about te...

Questions surrounding the Germanwings Airbus A320 air crash centre not just on mental health, but on a topic we deal with daily – access control. According to the flight recorder, the co-pilot of the doomed aircraft locked himself alone in the cockpit and deliberately slammed the plane into the side of a mountain in the French Alps, killing himself and 149 people. Early in the investigation and based on incontrovertible evidence from the flight recorder, Brice Robin (a prose...

Differences between standard data applications and the requirements of networks designed for IP video security applications are critical for your system's performance When the need to purchase a network switch arises, many IT directors immediately turn to two favourites, HP or Cisco. They have become to the networking environment what IBM was to computers: “No one ever got fired for buying IBM.” Certainly, switches play a crucial role in enhancing your network by i...

Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power. Many of these involve pan-tilt-zoom (PTZ) domes and heaters and blowers that require additional power. This development created two areas of confusion which is highlighted in this article by N...

Are network switches really designed for IP video security? The simple answer is no. As video security migrated to IP, a major concern for video security personal was the future of their positions in regard to system specification and control. After all, networks are networks, and they are under the control of IT directors. However, as transition occurred and the demands of IP video security grew, it became apparent that database networks don’t directly translate into IP vid...

Pelco is making its big comeback with renewed vigour and new lines of surveillance products to set it apart from the rest Working to Regain Momentum in a Changing Market: Most observers agree that Pelco lost momentum in the video surveillance market after the acquisition by Schneider Electric in 2007. Hervé Fages, senior vice president of Schneider Electric's video business, is looking to regain that momentum, guiding the surveillance giant in new directions as the mark...

   Analogue and digital resolutions are worlds apart Resolution in an analogue or digital world is similar, but there are some important differences in how it is defined. Phil Doyle, Managing Director (UK & Ireland) of Axis Communications, outlines these key differences. In analogue video, an image consists of lines or TV-lines since analogue video technology is derived from the television industry. In a digital system, an image is made up of square pix...
