Question A security system that works without Internet?

[CairoKolton]

Hey guys! I have an important question for you. I have recently come back to my usual working regime. Now I work from the office again. I also have lots of business trips. So, essay writer I leave a house for a while. I'd like to install some special system that will help me to control my place. But the issue is that I need that system to be not connected to wi-fi. When I am out I usually turn off my Internet router. So, there is no signal. I've heard that the Ajax systems work with a sim card, don't they?

Why would a SIM card be better than leaving your router on?

I'm curious about this as well. Can there be a security system that works without internet? I know that's how they charge money for a subscription service of keeping your camera footage and being able to contact the authorities is something is going wrong and you aren't home.
