Connect to your phone and activate the voice assistant as usual. 

Yes, voice-activated, I think it's quite responsive after you set up the sensitivity level in the setup file, 7 levels in total, from 10 dB to 70 dB. 

I've pretty much only used these batteries when doing video work, and haven't gotten any hum. Hope this helps. 

No, just open the deer camera's built-in WiFi via the controller and connect your mobile phone to it. then you can set the parameters of the game camera and download the recorded images & videos to your phone.
