How to catch a fast-moving criminals through cctv camera

[cctvdiscover]

We have a problem with some people who are destroying our mailbox.

They drive by at night very fast and smash it, and like the cowards they are, they beep their car horns and speed away.

Sometimes during the day they beep their horns and don't smash anything.

These are really abominable people, they belong to some crazy hate group. We literally don't know who they are but of course they seem to have decided they don't like us.

We want to catch them and bring these cowards to justice. The cops won't do a thing without evidence. So is there a high speed cctv camera that can be perched near the road (outdoors) or a high-zoom, high-speed camera that we can use indoors to capture their destructive activities and their license plates?

Either nighttime (IR?) or daytime are options we are considering.

Thanks.
