Is it reasonable for the property management office to cancel the security door and videophone in residential buildings for its own convenience?

This is unreasonable by rights. Because the security door and videophone in residential buildings are a complete set of supporting devices. The security door is equipped with an access card. Only the owner of this unit can enter and leave freely through the access card. If outsiders want to enter, they must find a specific person through videophone. Now the property management office cancels the anti-theft device for its own benefit, and the owner of this unit obviously lacks protective devices.
