To give some color for this post, it is being released in preparation for our next IP camera class starting next Tuesday. We want to help point out common problems and patterns of problems for attendees.
And, to be clear, we have made careless mistakes throughout the years as well. We continue to refine our materials and test questions to make sure that they are properly and fairly 'qualified' to best reflect the reality of today's technology and operations.
Being careful is a 'process' where one needs to be continuously vigilant about how they read and communicate with others.
