There are no pet proof motion sensors...only pet resistant motion sensors. Also, the pet "rating" that
a manufacturer gives a product assumes that the pet stays in one horizontal plane (like on the floor).
I see that you posted on this before. With any motion sensor, you're going to have to mask the areas
where the dog goes vertical, relocate the sensor(s), or both. And NO, you cannot mask the bottom
x feet of the room, unless your sensor has a pet alley lens (usually special order these days...and not
available for most motion sensors).
