The cost of the cameraThe cost of a camera was a complicated problem that involved many factors. According to documents [1] and [2], the cost of the camera module is estimated to be $77 (about $493), and it will continue to increase with size and price. In addition, the camera also included optical image stabilization, image sensors, and LiDAR sensors. The application of these technologies improved the stability and functionality of the camera, but it also increased the cost. According to the document [4], the total cost of the iPhone 13 ProMax was $438 (about 2800 yuan), of which the display accounted for 20% of the total cost and the camera accounted for 17.6%. However, the search results did not provide clear information about the specific details of the camera's cost and other factors, such as research and development costs, manufacturing costs, and customs duties. Therefore, it was impossible to accurately answer the question of the cost of the camera.

Invisible camera in the bathroomIt was reported that the city government of Seoul, South Korea, planned to send about 8000 more workers to patrol public toilets to check for invisible cameras to curb the act of secretly taking photos. According to Korean law, public bathhouses, toilets, and other places involving personal privacy were prohibited from installing cameras or similar devices. Violators would face a fine. However, invisible cameras were more concealed. They might be installed in hidden places such as wall sockets, air vents, ceiling corners, chandeliers, smoke alarms, tissue boxes, toilet uncleaners, and so on. Therefore, it was not easy to find the invisible camera in the bathroom. Some professional detection equipment could help detect suspicious corners, but the detection equipment on the market might not be able to effectively find the camera. In addition, some pinhole cameras might be "non-holed", with a transparent white block or a black block on the surface, making it more difficult to identify. Therefore, to identify the invisible camera in the bathroom required a combination of observation and professional equipment.
