Why choosing this app instead of a wifi camera ?
lots of people have an old unused phone
a phone has always a battery and is resilent to power outage
a phone has always a sim card slot and is resilient to internet outage
there is no expensive monthly subscription
privacy is better since videos are saved locally on the phone, and optionally uploaded on your own google drive and not on a propretary cloud
a phone has always a flashlight
