Hi, I have some usecases where I would need a lot of cheap webcams. One application is 3D scanning. The project 3DScan uses 100 Raspberry Pi cams: http://www.pi3dscan.com/ Here you find the costs of the hardware: http://www.pi3dscan.com/index.php/cost So I am thinking how we could make this cheaper. *MIP CSI2* The raspberry PI cams and all the cams used in mobile phones don’t use an USB interface. They use CSI-2 (*Camera* Serial Interface Type 2) with a 15 pin ZIF 15 socket. A widely adopted, simple, high-speed protocol primarily intended for point-to-point image and video transmission between cameras and host devices https://www.mipi.org/specifications/csi-2 *USB Webcams?* An alternative to the would be to use USB-Webcams and don’t have 100 hundred decentralized CPUs (Raspberries). The challenge is you need a multi-port USB interface like this: https://plugable.com/products/usb3c-hub97xxx/ One problem with this approach is that there are no multi-port solutions available. Due to high demand the above product is unfortunately sold out indefinitely. I assume that there would be also a bandwidth-problem on the PC side. *Use Raspberry PI Zero?* Using a Raspberry PI Zero would save some money: *https://www.pi3dscan.com/index.php/blog2/45-raspberry-pi-zero-v2 <https://www.pi3dscan.com/index.php/blog2/45-raspberry-pi-zero-v2>* https://electronics.semaf.at/Raspberry-Pi-Zero-W-Camera-Kit *Use an ESP32-PICO? *https://www.youtube.com/watch?v=B8Jq0G17WgQ Maybe it would not work with a cam which has more than 2 MPixels resolution. *Summary* For me the best would be to have a module where the cam-module already sits on the PCB. This would save connectors, cables (15pin!) and adaptors. Also I would prefer to have a waterproof case for outdoor usage. *Any Ideas???*
