My parents did this for me, and it worked like a charm.
Then they started changing the wireless network password. That's how I learned to set a wireless card into monitor mode, capture a bunch of packets, and crack WEP keys.
Then they started locking the router in a closet, and plugging it into a "timer" outlet (that itself plugged into a regular outlet) and just stopped letting electricity pass through at certain times. That's how I learned to pick locks.
Now I work on a red team. Thanks for the free training, mom and dad!
I've gotten in big arguments about a similar idea with my brother. I've told him I intend to monitor all internet traffic and phone activity in my house because I want my kids to grow up understanding that anything they aren't extremely careful to encrypt and protect can and will be read by the people they least want to see it.
He thinks I'm evil and children deserve privacy. I think he's neglecting a duty to teach his the hard truth that you are responsible for your own privacy.
I don't remember the specific product he used, but it was something very similar to this: https://www.amazon.com/Techbee-Countdown-Programmalbe-Electr...
The lockpicking was addressed with a more sophisticated lock, which was in turn met with a crowbar, which was in turn met with an increasing number of locks on the closet door, which was in turn met with me noticing the hinges were on the outside of this door and simply taking the door off the hinges without ever touching the locks.
I'm sure whoever buys my parents' house when they sell it in a few years will be a little curious about the one reinforced basement closet door with three pick-resistant 7-pin deadbolt locks, upgraded strike plates, and which is also the only closet door in the house with hinges on the inside, lol.
At least the hinges should make it clear they were trying to keep someone out, not keep someone in...
Not my proudest moment but I used to do anything to get extra time on the computer, I work full time as a security engineer now.
