TrustExecutor CCTV, yes for sure. Even just a systemd unit file using ffmpeg and rtsp cameras works great.
Abode, though, is a full security system with motion detectors, door/window sensors (reed switches), keypads, sirens, etc. You could build your own, but it'd be a ton of work. Basically the way to use Abode is to use their garbage app to set it up and then control everything through HomeKit or Home Assistant. But for the times when you do need their shitty app on your GrapheneOS phone, for now, just disable exploit protection.
