Three years ago, I paid for my security system to be converted to one that I could monitor remotely and was connected externally. The installers used Alula. It all uses low voltage wired sensors with a controller and a tablet attached to the wall. My three year contract is up and I would prefer to spin my own system and monitor it myself. I’m happy to invest in equipment and time installing stuff, but I’m not looking for a monthly subscription. Is there anything that would suit that I can use to repurpose the set-up I have?
