In home shooting mode, a notification about the presence of movement comes, and this turns on / off infrared lamps on the camera itself) I have not installed a flash drive yet, I have not used an external speaker. I use a month. Pros below: Shooting quality is good. Night shots are better than average. From the application, you can rotate the camera to the sides and much more. Extended mini usb power cord. Its cons: No power supply, bought separately. While shooting online, the recording is slightly noisy, but other sounds are heard well.
