Hello, yes, the intelligent camera can still function normally without inserting a Micro SD card. You can still view real-time monitoring footage and use cloud storage, motion detection, and push notification features. However, the playback of locally recorded videos and the ability to transfer them will not be available.
Note: To install the SD card, please locate the SD card slot on the device. If your device is a PTZ camera, the SD card slot may be located below the lens and you may need to push it up manually to access it.
