Create a video recording system using the 8GB memory of Raspberry Pi 4B
Request use -Videos are saved in the main memory (RAM disk) ・ You can monitor the image during shooting -Hardware that is easy to handle (I do not want to install a camera or microphone separately) ・ Continuous shooting for about 2 hours ・ Image quality that can withstand online video
What to use ・ Raspberry Pi OS ・ Motion
Motion is a video recording software that is often used in Linux. Since it has a function to record only when there is a change in the image, it seems to be often used for pet monitoring and security cameras. This time, motion detection is not necessary, but motion is used because it has a relatively large amount of information and seems to be easy to use.
When shooting a movie, we want to check how it looks, so we need a function to monitor it. motion has a web server function and can monitor the shooting status with Port: 8081 (default). It may be convenient because it can be seen over the network.
Since you can use a camera over the network, you can also use other Raspberry Pi cameras. Try installing one or two turtles at the time of shooting.
The configuration file is here /usr/local/etc/motion/motion.conf emulate_motion Type: Boolean Values: on, off Default value: off Always record even if there is no movement in the video
movie_max_time Type: Integer Value: 0 (infinite) --2147483647 Default: 120 Specify the maximum length of the video in seconds. If 0, there is no size limit.
