I’m somewhat surprised that there’s no purchasable solution to this problem as all of the technology to make a short range drone interdiction system already exist. To detect one all that’s necessary is an appropriate camera setup and a system hooked to it capable of recognizing them, both of which are already prevalent in the market. Add an inexpensive laser range finder so the system can know if the drone is truly over your property and at an altitude acceptable for interception.
Once that’s done it becomes a matter of how to interdict the drone. One relatively safe option would be for the system to deploy a high speed short range interdiction drone to overfly the other drone and drop something on top of it meant to snarl its rotors, for instance fishing line with weights.
None of that is necessarily easy but its certainly doable.
Almost. Any drone that weighs more than .55lbs must be registered with the FAA and as part of that it is required to be compliant with RemoteID. RemoteID requires the drone to broadcast both its identification and location of the control station.
If it’s being operated over a home then it will almost certainly have to follow the rules on Operation Over People and those can be quite restrictive, especially for drones that weigh more than .55lbs.
There ARE Federal Rules for this in the United States, drone operators cannot legally fly any type of drone anywhere they want at any time.
