I am looking for an app that can turn an old smartphone into a home security alarm / baby-monitor / motion sensor.
Probably by camera or microphone.
silently trigger some notification.
Preferably by email, sms or call.
automatically disarm itself, when certain other smartphones are nearby.
No alarm should be raised when a person with a "friendly" smartphone enters. For example by delaying any alarm for a minute and checking the local router's wifi network for the presence of those whitelisted devices. Another option would that the "friendly" phone runs another app that disarms the alarm.
automatically rearm itself, when all such friendly smartphones leave the area.
No manual interaction should be required to re-enable the alarm.
It should not:
- require uploading photos or sound to some sort of proprietary cloud service. Does not matter whether that cloud service claims that all data is encrypted.
Purchase price is not a concern, but a non-subscription based app would be greatly preferred. Absence of ads and non-suspicious app permissions would be great bonuses.
