一个简单的适配于A1mini的旧手机监控摄像头，可以得到不错的画质和帧率，你可以使用https://play.google.com/store/apps/details?id=com.shenyaocn.android.WebCam&hl=zh&gl=US这个软件，将IP连入orca，或者将网页映射到外网，以便不在打印机旁更好地观测打印质量，如我使用的小米6为例，可以得到4k 30fps，画质在聚焦时，可以看清每一层的层纹。

You can easily repurpose an old smartphone as a monitoring camera compatible with A1mini, achieving excellent video quality and frame rates. One recommended app for this purpose is https://play.google.com/store/apps/details?id=com.shenyaocn.android.WebCam&hl=zh&gl=US. You can either connect the IP to Orca or map the webpage to the external network. This allows for better monitoring of print quality, even when you're not beside the printer. For example, using my Xiaomi 6, you can achieve 4k 30fps video quality, and when focused, every layer's texture becomes clearly visible.
