I dunno about his "emplacing" the cameras, which implies to me that he somehow constructed these devices,  but it would seem that it's true that "significant planning" went into his activity. That sort of "spy gear" can be ordered online from China all day long - the glasses, the key fob (look up "808 camera" on Google), even motion/sound activated surveillance cigarette lighters can be ordered from China and sent right to your front door, courtesy UPS and Customs.

One may wonder if focusing his earlier education towards medical care was done to employ such surveillance
and get his rocks off via a type of voyeuristic enjoyment. God knows what devices are still in his office and
workplace.

"...It was heard Mathurine made 'implausible' suggestions that his motivation was not sexual..."
Maybe he collected these images for something involving the darker-side of the internet? But since he found
it easy to lie to his clients and female acquaintances, who knows.
