I recommend the novel camera to students.

The 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.

😋I recommend the following two novels to you: 1. "Dr. Yin, You're Blushing" was a modern romance novel. It told the story of the female protagonist and the male protagonist who were university classmates. They were both top students, and the senior and junior were in a sweet relationship. There would be some abuse in the middle, but it would still end happily. Love was when you happened to appear in my life at a specific time. This was the love between Qian Miao and Yin Chenyi. Shuang Jie, highly favored, don't worry and enter the pit ~ 2. "The Top Student Couple Doesn't Study" was a romantic youth-youth campus novel. It was about two big shots who didn't study and fell in love all day long. Two top students had a two-way crush on each other. The male lead was the first to fall in love! There was no weak side, and they were evenly matched. I hope you like this fairy's recommendation. Muah ~😗

Well, not being able to use the camera in the story could be because of software issues, or maybe the author intentionally excluded it to add mystery or challenge to the situation.

There could be a few reasons. Maybe the camera settings are incorrect, or there's a problem with the software. Sometimes, it might be a network issue preventing the proper functionality.

Sometimes, it might be a compatibility issue between your device and the story app. Update both your device's operating system and the app to see if that fixes it. Another possibility is that there's a temporary server issue with the app, so waiting a while might help.

Maybe there's a problem with your device settings. Check if the camera permissions for the app are enabled.

In most cases, you can. However, it's important to check the event's rules and regulations. Sometimes, professional-grade cameras or those with detachable lenses might have restrictions for security or copyright reasons.

Maybe there's a technical glitch. Try restarting the app or checking your device settings.

It 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.

😋I recommend " A Gangster Begins From a Manga ". This novel about urban life is about a student named Xu Fan. He was forced by the system to walk the path of a gangster and run further and further away. The plot was interesting and the protagonist had a distinct personality. It was very intriguing to read. I hope you like my recommendation.😗
