I did not find this to be the case. My laser pointer operated off a pair
of AA batteries. A new alkaline set provided approximately 60 hours of
sufficient laser energy to turn off the street light. The symptom of
run-down batteries was that the aim became more and more delicate, else
the street light would not turn off.
In regards to aim, I was lucky enough to have a second floor bathroom
window with a straight shot at the sensor. My cat was occasionally a
problem, so too my wife, who would sometimes cause the tripod to jiggle
when she entered the room.
I also had to trim my neighbor's hedge periodically to keep the topmost
shoots from interfering with my line of sight to the sensor. Being
somewhat unsure how they might feel about this, I did it at night,
walking on the pitched, wood shake roof. It sometimes got "exciting".
Cheers,
Paul
