How to deliver adequate power to security devices in industrial sites

With security found in more and more industrial settings, advanced and heavy-duty network devices are needed on the edge to make implementations effective. Amid this trend, the first major challenge is to deliver enough power to these devices. Increasingly, traditional PoE standards, IEEE 802.3af/at that deliver 15.4W and 30W of power, are proving insufficient in this regard. A hardened 60W PoE switch, on the other hand, can better the power supply needs of industrial users.

How to minimize EMI impact on mission critical video surveillance

Electromagnetic interference can degrade the total performance of a video surveillance system. Therefore, the EMC (electromagnetic compatibility) of the electronic equipment should not be overlooked when a video surveillance system is applied to environments with high-voltages present, such as power plants, factories, transportation and infrastructure.
In this Detektor Security Academy article, Detektor has employed the expert knowledge of Ethernet product company, Etherwan, in order to explain how both products and surveillance systems should be designed in terms in of EMC in order to negate any problems that may occur.

Lighting for network cameras

Achieving a well-lit environment for network cameras during night time is not an easy task. The best way is of course to go out on scene and try out a chosen camera, lens and lighting combination in real conditions. However this is not always possible, but in reality, many systems that are set up during day time conditions may fail to achieve effective night-time images. Because of this, Raytec and Axis have created this practical guide, based on a series of test nights throughout the dark winter months of 2011 and 2012, which is designed to help users get a long way on the path to achieving perfect CCTV lighting for a network system at night.

Effective IP surveillance with Power over Ethernet

Power over Ethernet technology describes a system to pass electrical power over Ethernet cabling, along with data. This means that a network device can be powered and operated using the same cable as for network connection, eliminating the need for power outlets close to an IP camera, for example. However, in order to save money on installation and increase the security level by using PoE, it's important to keep certain key points in mind when dealing with the technology. This article will guide you through equipment and standards within PoE that will help you succeed in the field.

Infrastructure for efficient IP surveillance

When talking about IP surveillance the first things that spring to mind are often cameras, resolution, storage or video analysis. The backbone of the systems, the network infrastructure that makes everything possible, is often left behind in the discussion. However, to obtain maximum effect and image quality you need efficient use of available bandwidth. The communication between the systems components is made by copper, fiber or wireless systems. The attributes of these components are the key to a successful installation. What are the important things to consider, and how to choose the right products to benefit from the most reliable and functional application possible are two of the questions that this educational article will address.

Intelligent Video Analysis

In the security industry the theme under discussion has several names, two of the most frequently used are, IVA (Intelligent Video Analysis) and, VCA (Video Content Analysis). There are many variations to these, but VCA is the most accurate term to describe this evolving security field, as it is difficult to label a technical system as intelligent in the true sense of the word. Common for all the different definitions of VCA is that they relate to a technology that is used to analyse video for specific data, behaviour, objects or attitude.
