Mobile phone card GSM SMS alarm burglar alarm device, is it easy to use?

At present, all gsm mobile phone card alarms on the market use SMS technology, including remote control with mobile phone app, which is also the most reliable remote control method at present. For the safety system, reliability is the first. If it is not reliable and timely, security and anti-theft are just floating clouds, so now some companies have launched a dual anti-theft alarm system of voice and SMS, such as Familia in Shenzhen. They use the mature tts technology (speech synthesis technology). When the protection zone is triggered, firstly, they automatically dial the owner's phone, and send voice after connecting the phone, just like 10086. Reply to 0 can directly control the alarm host to disarm. What happens when I reply to 1? I don't remember clearly, I just want to guard against theft, and I don't care about spending a few more dollars. In addition, if you are not triggered, there is no cost. Our company used to use wired telephone, but now it has changed, and it feels great.

I have typed so much, I hope to adopt it.
