At IPVM, we deal with many PR / marketing people, who are typically quite bad. Either those who are afraid or incapable of communicating anything or those that think they can lie to you and get you to publish their canned pitch.
One marketing / PR pro who has stood out is Gloria Nichols. We interacted with her while she was working with Eagle Eye Networks. She did a good job, under some difficult circumstances, advocating her position in a straightforward and honest manner plus getting clear answers to the detailed questions we typically ask.
Video surveillance manufacturers who are looking for marketing / PR assistance should consider Gloria.
