I just purchase a wireless Logitech mouse off of amazon refurbished for $10. It works right out of the box. I didn't have to download any software. I just plugged in the receiver in the usb port on the front of my Reolink NVR and turned on the switch on the mouse and it worked!

Yes please add that function to the mobile app for ios! I am a brand new customer and I am loving my 4mp camera system but I am hoping that they will add the feature to look at playback and see where the motion is on the mobile app.
