I have several kites.
My biggest one is a reasonably large parafoil (no sticks - it's like one of those 'square' parachutes, but smaller). I've used that to raise a camera to take aerial photographs. I pay out about 100 feet of line, then attach the camera to the line and pay out more till I get the camera to the height I want. Then I have a radio control that allows me to point the camera in the desired direction and work the shutter.
I fly that kite on 100 kg breaking strain line. On a calm-ish day you still need gloves to protect your hands and strong arms to wind it back down. If it's windy it gets a bit dangerous and you really need a vehicle or fixed object to tie the kite to.
I have some regular size dual string stunt kites too. Those need a reasonable wind to fly well - the sort of day when if you drop some litter it will blow along the ground and take a bit of catching.
It depends on the kite type and size how much wind you need to fly them. Some kites have an adjustable bridle so you can alter the 'angle of attack' to the breeze. By adjusting the bridle and/or adding more or less tail to a kite you can often get them to fly well in different wind conditions.
