Unreasonable and illegal No matter what the purpose of the person who installed the camera is, it is very unreasonable and illegal, so the other party must bear the corresponding responsibility for this matter. In fact, there could have been a good solution to this matter. If you really don't want the other person to move away, you can communicate with the other person. And find out why the other party wants to move out. If there is really no way, even if you take out these videos and threaten each other, it is impossible to stay, and you will get into trouble.
The correct solution If the other party really wants to move out, in fact, the remaining roommates can choose a roommate to share, which can solve this problem very well. However, by installing hidden cameras, recording some private pictures, and threatening the other party not to move away with pictures, there are great problems, which have violated the legal basis, so this is the most wrong solution.
Pay attention to your privacy and safety. After this incident was exposed, many people who shared a room outside carefully checked their living environment, because this kind of thing could happen everywhere. At present, some pinhole cameras are so secretive that they will not be discovered without careful observation, which also poses a great threat to the privacy of many people living outside. Therefore, people living outside must protect their privacy and safety, and choose to call the police once they find something wrong.
