What's your opinion on using laser beam systems for outdoor home security?

Hey everyone, need some advice here. I’m thinking about setting up a laser beam detection system outside my place. I’m looking for something with about 3 or 4 beams stacked on top of each other, so they all have to be disrupted at once to trigger the alarm.

I want to avoid false alarms, like from a falling leaf or something. Do you know if there’s a system like this already available, or am I going to have to build it myself?

Any success stories or recommendations from anyone who’s tried something similar?
