I mount the sensor(s) in a different location from the lamps, wherever gives best sensing performance. I pull 3 conductors to the first sensor or lamp, then 4 conductors between each sensor and lamp: ground, neutral, always-hot (black) and switched-hot (red). If it's just a branch up to the lamp, always-hot can be omitted.
From there it's a fairly simple affair: sensors get wired to neutral, always-hot and switched-hot. Lamps get wired to neutral and switched-hot. (and grounds, of course.)
You don't want a sensor which doesn't take a neutral; these power themselves by leaking power through the light bulbs, which makes them incompatible with modern efficient lighting. You also can't have two of them.
Also, place lights so they don't flash directly in people's faces as they walk up the normal path and hit the detection zone. They should be off to the side so the light is welcoming, not irritating.
The sensors I use play nice with one another, so there can be more than one sensor. Any sensor supplies power to switched-hot, and all the lamps light. One of the sensors can be a switch, timer switch etc.
