In the novel, 'The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it, moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard.' This quote shows how the technology in Oceania is used for total surveillance. It's not just about listening in, but also seeing everything the citizens do, leaving no privacy at all.
Another quote could be 'The telescreens could be dimmed, but there was no way of shutting them off completely.' This shows how the surveillance technology in the novel, the telescreens, were an inescapable part of people's lives. They couldn't have true privacy as the Party could always access the view from the telescreens, even if they were somewhat dimmed.
A key quote is 'We know that no one ever seizes power with the intention of relinquishing it. Power is not a means, it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship.' This shows how the surveillance state in 1984 is part of the Party's hold on power. By constantly watching the people, they can prevent any uprising or deviation from the Party line.
The quote 'There was of course no way of knowing whether you were being watched at any given moment' ties into the theme of psychological manipulation. The uncertainty of being watched makes the citizens live in fear. This fear is used by the Party to manipulate their thoughts and actions. It's not just about physical surveillance but also about the mental and emotional control it exerts over the people in the novel.
There were several possibilities for the surveillance camera to turn black and white. First of all, the camera might have used a color-to-black chip. During the day, when there was sufficient light, it would display a color image. At night or when there was insufficient light, it would switch to the infrared light mode to display a black-and-white image. In this case, you can change it through the function settings. Secondly, the image of the camera may malfunction, such as color storage and transmission problems, or the aging of the camera and the camera, which may cause the color to turn black and white. The solution might be to change the camera or the camera. In addition, the poor connection of the surveillance video circuit could also cause black-and-white images, which could be solved by re-welding the spot where the weak welding was. In short, to solve the problem of the surveillance screen turning black and white, he needed to calmly analyze, find the problem, and take corresponding solutions according to the specific situation.
The Sunshine Restaurant Surveillance System was an intelligent monitoring system launched by the Hangzhou City Market Supervision Bureau. The system used digital technologies such as the Internet of Things, cloud video, artificial intelligence, and big data to establish a command center and a three-party governance model for enterprises, the government, and the public to achieve supervision and management of food and beverage units. The system included the video surveillance mode of Sunshine Kitchen and the " Food Safety " app. Citizens could view the kitchen of the food and beverage unit through the "Food Safety" APP on their mobile phones, check the source of ingredients, license information, food safety level, personnel health and inspection information of the supervision department, and evaluate tableware disinfection, dish quality, environmental hygiene, etc. The system would also be applied to school management, rural banquets, online ordering, and other scenarios to improve the food safety supervision level of Hangzhou City.
There were several possibilities for the surveillance camera to turn black and white. One possibility was that the camera's function was limited. When there was sufficient light, the camera would capture a color image, but when there was insufficient light, the camera would automatically switch to infrared night vision mode, causing the image to turn black and white. In this case, you can change it through the function settings. The other possibility was that the camera's image had a malfunction, including color storage and transmission problems, or the camera and the camera were aging and needed to be replaced. In addition, the problem with the video transmission line could also cause the surveillance screen to turn black and white. It was necessary to check the connection line and replace the cable. If the above methods cannot solve the problem, it is recommended to seek the help of professional technicians.
The surveillance cameras could have captured the Black and White Ghosts for one of the following reasons: the surveillance camera was in a dark environment, which resulted in the display of black-and-white images; the surveillance camera used a chip that turned from color to black, which would automatically switch to black-and-white mode when there was insufficient light; the surveillance camera's image malfunctioned, which could be due to color storage and transmission problems or the camera's aging; the surveillance video line was poorly connected, causing problems with the image signal. To solve this problem, you can check if the infrared light board of the camera has a weak red light, replace the camera or camera, re-welding the spot, or change the function settings according to the operating manual.
The dedicated traffic card for surveillance cameras was an Internet of Things data communication card designed for surveillance cameras. It was more cost-effective than traditional data cards. It could choose the appropriate data package according to the scene and functional requirements of the surveillance camera, thereby reducing costs. This kind of data card could break through the limitations of traditional data cards. According to the specific usage of the equipment and the environment, the appropriate data package could be selected to effectively control the cost. In addition, the fee for the dedicated data card for surveillance cameras was relatively low. There were more types of data cards than ordinary data cards, which could effectively reduce the cost of use and avoid wasting network costs. Therefore, choosing a dedicated traffic card for surveillance cameras could meet the needs of surveillance scenes, reduce costs, and improve the use effect.
