Do hotels with lower star ratings have hidden benefits in terms of room safety?

Hotels with lower star ratings have no hidden benefits in terms of room safety. According to the relevant public information on the website, the personal safety of low-star regular hotels can be guaranteed, but the privacy cannot be guaranteed, because many hotels have secretly installed monitoring equipment. Check the air conditioner, lampshade, ceiling, cosmetic mirror, smoke sensor, vase, socket, TV cabinet, etc. Pay special attention to the equipment and furnishings facing the bed. Larger monitoring is more recognizable.
