Her rapport with the 26-year-old Wellingtonian, who is legally blind or partially sighted to come under the category of "tandem class blind", has gone swimmingly smoothly.
"She gets around quite well but she can't drive or ride a bike on the road.
"I'd love to be able to know exactly how blind she is but, of course, I'll never be able to do that," says the Hawke's Bay Ramblers Cycling Club member of Cameron.
Words such as trust, cohesiveness, patience, inspiration and timing come into the equation but, most of all, a standard of kinship is required that is up there with that of twin siblings.
"We have three hours on the road so we really get to know each other quite well [as riders]," says Van Kampen of a training schedule that entails two three-hour track-and-road stints a week alone.
No doubt there's some banter between the pair, as one would expect when two people are locked into a confined space for a common goal.
So is there a chance of mutiny on the two-wheeler when one party or other feels pressured?
Laughter prevails before Van Kampen clarifies who calls the shots, almost by default.
"It's not that bad for me because I'm the boss, if you like. I say when we should stand up [to tame a hill] or sit down and so far so good that we're getting on quite well together."
It's humour that becomes a form of insulin to fuel each other when lethargy kicks in, no different to tactics Foy and Thompson employ.
Paralympian Kate Horan, Foy, Van Kampen, Cameron, Byron Raubenheimer and Stephen Hills are all making their debut in para-cycling.
Cameron and Van Kampen, who competed at the Para-Cycling World Championship in Italy in March, are clued on the 3km pursuit track as their main event in Rio.
The 1km track race, 25km time-trial on the road and the 80km road race are also on the agenda.
"For the next three months we'll be in each other's pockets so we should have some good times ahead."
Their camaraderie is such and the returns so gratifying that Van Kampen is adamant nothing will nudge her from her sense of commitment to any union.
"If anyone were to ask me if I have the opportunity to swap to go to Rio as an individual, able-bodied rider I'd turn it down," she declares, emphasising the satisfaction of that nuclear collective environment that surpasses athleticism and takes her to a realm of grasping something more meaningful - life skills.
"If anything, you grow as an athlete."
That is not to say Van Kampen has given up on her individual quests, although a prerequisite for para-cycling is a professional cyclist must not be active for 24 months in any UCI Tour in order to apply to be a pilot.
"I'm still riding my single bike, race at the nationals and I'll have the opportunity for racing in the build up to Rio but obviously tandem racing is my main focus."
She and Cameron jet off to Beaumont, Canada, at the end of this month but while Cameron will return with the team in July Van Kampen has the chance to remain in Alberta to do some road work before the team join up again in August.
The combinations in the team will be confirmed in July.
Van Kampen's parents, Vanessa and David, are immensely proud of her achievements but "gutted they weren't given notice to go to Rio to watch".
"They'll just have to wait for Tokyo [Olympics in 2020]," she says.
