How does a laser pointer drive away crows?

I'm thinking of buying a high power laser pointerr to avoid crows, I'm in trouble because crows damage house equipment and my elderly parents are threatened. Please tell us the point of purchase, such as strength, color, price, durability, manufacturer, power type, etc. I didn't think about other uses, so I wanted to improve it as cheaply as possible, the most popular star watcher of the year was this laser, and many people bought and responded.

Laser pointers can repel crows, animals, flies, and mosquitoes, as well as objects at extreme distances. In the case of neighborhoods, if pointed with physical means such as a laser pointer, there may be shadows that make it difficult to see. Meetings, small and precise things Scenarios that require directions to dangerous places Physically pointing at things that are hot or cold, in water, dangerous or harmful in themselves, etc. are dangerous.
