Good point about the App but the password is not a problem as it is easy to reset. The biggest problem I see with all these outdoor cams is accessibility and theft. For a battery cam accessibility for recharging is necessary. For both cams they have an on-board SD card, lose the cam . . .
There are so many ways of defeating these cameras, you just hope they get the picture out before they are nobbled. The one time we had an intruder they disabled the internal camera but not before it sent an alert. The police reacted within 20 minutes.
As they say, you know most vulnerabilities better than a burglar. You hope to get an alert before they get in.
