Is it illegal for counterfeiters to go to the supermarket to hide cameras and shoot videos?

Whether it is illegal for an individual to install a camera depends on the specific situation. It is illegal to claim compensation if the other party is not suspected of profiting from it and has not caused calculable economic losses. Restrictions on installing cameras in public places:

1, installation must be publicized to inform relevant personnel;

2. The installation scope must be limited to the scope that does not directly invade privacy;

3. You can't disclose the supervised content at will, otherwise it may also involve infringement.
