The following is related to the car modification camera (camera): * * 1. Modifications of 360 panoramic camera ** 1. * * installation process ** - When modifying the 360 panoramic video system in the car equipment store, the installation process was more complicated. For example, the installation master had to dismantle the interior first and remove the big screen of the car to test whether it could display normally. For a Kia car, after confirming that the big screen of the car could be displayed normally, drilling and tracing operations had to be carried out, especially the installation of the probes on the rearview mirrors on both sides. If the original car had a reversing camera during the installation process, it might be useless. The rearview camera had to be reinstalled to match the 360 image. 2. * * Function Status ** - Take the modified 360 video function of a car as an example. When the turn signal was turned on, the left or right camera image would be awakened. After the reverse gear was put on, the 360 video would be displayed. However, there were also some problems, such as the display might not be clear, the line of sight when reversing was not as wide as the original car, and if the left and right images were activated when using the navigation and then returned to the map, it would be relocated (there was an incompatible problem). 3. * * Instalment Skills ** - There were some special tools and methods to install the 360 camera. For example, he would first make a small hole, then use a tool with a level and an angle that could be adjusted to screw it onto the hole. After tightening the screw, he would use a heating tool to soften the plastic and pull out the bulge to install the camera. 4. * * Effects of different vehicle models after modification ** - In Shangqiu's car modification, after the 360 panoramic modification of the cars such as honda, toyota, nirvana, and volkswagens, all the turn signals would display the left and right images and the front and rear wheels would be clearly visible. When the reverse gear was engaged, there would be a clear reverse image with a follow-up track. When the forward gear was engaged, the front perspective would be displayed, and there would also be a four-way driving recorder function. * * 2. Camera-related special circumstances ** 1. * * Information Security ** - In new energy vehicles, cameras may involve information security issues. For example, the camera in the car could be used to take photos, hold video conferences, and even track eye movements to improve driving safety, but it was linked to information security (including network security, data security, etc.). Byd had taken measures in this regard. They installed a manual cover on the camera. When they didn't want to use the camera, they could block the camera by gently sliding the cover. This practice had obtained the certification of the relevant system and had a good effect in information security protection. In addition, the car would also set the camera's permission through the mobile phone app. 2. * * In terms of camera performance ** - For example, the AITO-Wonder was equipped with 8 million high-definition cameras inside and outside the car. The camera outside the car had the characteristics of super wide angle, super visual range, and zero distortion, which could easily take a large road and share the beautiful scenery. Car modification cameras needed to consider various factors such as function realization, installation process, compatibility with the original car, and information security. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
