The Three Primary Technologies for Night-time Video Surveillance - Master these and you'll never be in the dark

There are lots of challenges in performing video surveillance at night. The optimal solution for a particular application will depend on the requirements for the specific application.

The "best" system design for a specific video surveillance system that includes imaging at night will utilize one of the three primary night vision technologies: low-light imaging, thermal imaging and near-infrared illumination. In this article, these three technologies are explained and the advantages of each reviewed.

 

Tips on Creating Awesome Night Vision Digital SLR Photos
Even the best digital SLR cameras simply do not have sufficient sensitivity to capture adequate, low-light, usable images. Night vision modules are the ideal accessory. This article provides important guidelines for producing awesome night-time photos when using a night vision module-enabled digital SLR camera. Follow these guidelines to assure the best possible image quality.

Also discussed are such areas as report writing, interrogations, locating missing persons, industrial and commercial undercover operations, accident investigations, business and industrial espionage, and legal constraints. Expanded and greatly updated chapters on information technology, modern equipment and methods, optical-related visual aids, VIP protection, and managing a detective agency are provided. In addition, the text is generously illustrated with photos, diagrams, and document examples. This new edition has been prepared with the greatest attention to both textual quality and production details. The book will serve well as both a learning tool and a source of reference. The primary target populations of this book are individuals who desire to become a private investigator, individuals new to the profession, and those who desire to broaden their professional knowledge. Others who will benefit from the information the book provides include insurance professionals, attorneys and paralegals, police officers and other government investigators, and law and criminal justice students.
