Some of them could be true. There are many cases where strange figures or anomalies are caught on camera that can't be easily explained. However, some might also be faked for attention or due to camera glitches.
One of the famous ones is the Brown Lady of Raynham Hall. A photo taken in the hall seems to show a ghostly figure on the staircase. Another is the Amityville Horror case where some claimed to have captured strange things on camera during the supposed hauntings.
In most cases, it's likely a hoax. People might use photo editing software to create the appearance of a ghost for attention or to play a prank. But there are some instances that are really hard to debunk. There have been reports of orbs in photos that some believe are spirits. However, orbs can also be caused by dust particles reflecting light in a certain way. So, it's really a mystery in some situations.
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.
One famous example is the photo from the Waverly Hills Sanatorium. There are claims of ghostly apparitions in the photos taken there. People say they see figures in the hallways and rooms. But again, it could be due to the old and dilapidated state of the building which might cause strange lighting effects and shadows that look like ghosts. There's also the Gettysburg Battlefield ghost photos where some see soldiers' apparitions, but it could be just tricks of the light on the historic and somewhat spooky landscape.
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.
One scary security camera story could be about a family who installed a security camera in their old, creepy house. One night, they checked the footage the next day and saw a shadowy figure moving slowly down the hallway. It had no distinct features but seemed to be floating. They were so terrified that they called the police. But when the police arrived and searched the house, there was no sign of anyone breaking in or any explanation for the figure on the camera.
