Josh White - ArticlesThe Three Primary Technologies for Night-time Video SurveillanceThe three primary technologies for night-time video surveillance are: low-light imaging, thermal imaging, and near-infrared illumination. Understanding the advantages and disadvantages of each technology will assure that a surveillance system delivers the desired performance
at night. Testing Building Envelope Systems Using Infrared Thermal ImagingThe structures we live and work in are susceptible to quality and performance problems during construction and maintenance that can impact performance and may, in some cases, render them dangerous. Regardless of the building type involved, infrared thermography can provide remarkable, nondestructive information about construction details and building performance. Guidelines for Performing Infrared Inspections of Motor Control CentersWhether it's your first infrared inspection or you're a veteran with hundreds of surveys under your belt, it is important to realize that in order to successfully identify and analyze thermal anomalies, it is beneficial to understand the operation of the equipment under inspection. This paper will provide guidelines for inspecting the motor control center (MCC), identifying key components and potential problem areas, illustrating both common and not-so-common thermal anomalies. Integrating Thermography With Your Cmms-eam SystemsMore and more companies are investing in CMMS systems to organize the complex task of managing capital equipment and facility infrastructure whether it is process or production equipment or building systems like HVAC and computers. CMMS is a great organizational tool but cannot directly monitor equipment conditions. Nfpa 70e and Its Impact on ThermographersThere continues to be a great deal of activity surrounding the update to NFPA 70E scheduled to be published in October 2008. For the proposed 2008 edition of NFPA 70, National Electrical Code® (NEC®), the Technical Correlating Committee (TCC) received 3,668 proposals and 3,206 comments during the revision cycle. For those of us involved in working with energized electrical circuits the outcome of the new standards will likely impact how we do our job. Nfpa70e, Arc Flash and Safe and Efficient Thermography PracticesEstimates indicate that 10-15 serious arc-flash incidents; those that result in burn injuries requiring treatment in a burn center, occur each day in the U.S., so it is not surprising that awareness of the hazards associated with arc flash continues to grow. Concerns about operator safety are causing inspectors of high voltage switchgear to adopt new practices and new equipment. We will examine the impact of new safety practices. Periodic Infrared Inspection Best Practices - Route Based SurveysAbstract Infrared thermographic inspection is an established PdM inspection modality. Recent advances in infrared camera platforms have created a new class of infrared imaging instrument which incorporates pen-based computing and application specific software into a powerful thermal inspection data logger with many traits similar to mature vibration data collection systems. Locating Levels in Tanks and Silos Using Infrared Thermal ImagingInstrumentation for locating levels in tanks and silos is often unreliable. The need for precise information about levels remains necessary, or even critical, in many instances. For example, in one situation a thermographer was employed to verify a liquid level in a large storage tank along the Gulf Coast prior to the arrival of a tanker ship. Understanding Infrared Camera Thermal Image QualityWhen looking to select an infrared camera, it is extremely important to better understand the attributes of these cameras that most impact the quality of the infrared images that are produced. This paper covers the three primary areas that influence thermal image quality: pixel resolution, thermal sensitivity and fixed pattern noise. Each area has a significant impact on thermal image quality. Tips on Creating Awesome Night Vision Digital SLR PhotosToday's digital SLR cameras offer full control of aperture, shutter speed and ISO settings enabling the capture of excellent usable images in low light that were not possible. However, in many situations such as photographing scenes at night with very little ambient light, or telephoto photography at night at a distance, even the best digital SLR cameras simply do not have sufficient sensitivity to capture adequate images. In these situations, night vision modules are the ideal accessory.
