Should be simple but never is, help pls

["No" <no@xxxxxxxxx>]

Hello - I would like to install motion detectors on all 4 sides of my house.
These motion detectors should only operate dusk to dawn. When motion is
sensed on any of the 4 detectors it should trigger all 5 lighting circuits
to turn on (Or selectable circuits).

I do not care if its X10 or any other command type solution. I can probably
run low voltage wire to each switch or light if necessary.

I do not want batteries in the loop. If a switch replacement is required it
must be a toggle style, not a decora style. Dimming is not important, lights
are incandescent.

I also want the system to be robust and reliable.

Any suggestions where to look? I've been to smarthome and cant seem to find
what I need/want.
