Privacy and access question

How do I prevent others from accessing and altering camera footage? My kids can download the app and concert to the cameras in my house. Which also allows them to delete the footage.

they can download the app but unless they have your login credentials or you “share” the cameras with them they can’t even see the cameras.

if they have your credentials. change them asap. and if you’ve shared cameras, you can unshare them and take away their ability to access them.
