I’ve had this idea for a long time but now Rust is getting a lot of new features, don’t discount this one. Cellular alerts sent via text message when your base is getting raided. Have alerts set to you when certain panels/ areas are breached or damaged a certain amount, giving you the time to respond.
No more will you lose any sleep about getting raided, worry when you are away at school or work, it will give you peace of mind! The possibilities are endless with this one- you can alert your friends to defend your base, set off some sort of traps, opens up the possibility to some potentially interesting blueprints, and crude electronics. You are already creating a code lock, salvaged circuitry could be a component you could either craft or find somewhere as a part of this. If Rust is supposed to be post-apocalyptic with landmarks of things past, it would not be too far fetched to have pieces of technology you could find to use for this purpose. There are airdrops, there can be crude electronics. If this idea were to really take off, Garry could release an app which could let you monitor the security system of your base. With salvaged recording equipment, you could make security cameras and also set them up to stream the people who raid your base. This might also let you see how raided your base so that your could apply some self help and try to get your loot back from those people.
There is no way I am the first person who has thought of this before but I just needed to share.
