Can you remove the camera of the mobile phone and connect it to the memory card with an independent processing system? For the guidance of experts, it is just an independent monitoring system.

What you said is very similar to some webcams on the market now. The webcam I'm talking about has an SD card, which can store pictures.

If I guess correctly, although you said there is an independent processing system, you still want to use the mobile phone motherboard to run this system. I said a few things that I thought were the main points, hoping to help you.

1, the current mobile phone processing function is very powerful, which can compress the original data of the camera and save it in the memory of the mobile phone or the SD card. This can't be done by the original mobile phone, but the current mobile phone can, because it is fast enough.

2. Independent monitoring system. What I understand is that without external auxiliary equipment, the original data of the camera can be collected and compressed by the motherboard and stored in the SD card at a fast enough speed. The first point above has explained that this is possible. In other words, the mobile phone can be considered as an independent monitoring system.

You also said: You can remove the camera of the mobile phone and connect it to the memory card with an independent processing system. This seems different from my understanding. Looks like you're counting on not using the phone motherboard. So the simple way is to have an ARM9 processing platform now. You can search for such a development board in Taobao. With such a development board, you can develop programs, run the system and realize what you need on the development board of ARM9.

If your ultimate idea is that you need this system to run independently, for example, if you put it in the wild and you can film the life of wild animals, then your biggest obstacle may not be the system itself, but the power problem. Although there are such systems everywhere now, it does not solve the problem of too much power consumption. Generally speaking, it can only run for a few hours. This is a possible bottleneck in your final use. You can think about it first.
