Big Brother Edward?

Slay the spire and FTL are my two go-to travel games. They don’t use much battery and give hours of entertainment

The security issue you mentioned I think only affected when they handle access to the cameras. I think you can set up a VPN and then turn off remote access on the NVR, so it seems possible to avoid that issue.

That being said that’s a lot of work for something they should have handled securely in the first place and doesn’t give me much confidence about their security in general.
