Is there a wireless remote alarm used in the mountains?

A set of alarm host can be installed at the place where all probes can receive at the same time (it can be used as a front-end host, and it is best to insert a SIM card, but the premise is that there must be a mobile phone signal), and the power supply uses solar panels+batteries to supply power to the probes and the front-end host; Finally, there are two schemes: 1: a central receiver can be installed at home to realize that the alarm can accurately distinguish which probe is triggered (the cost is higher than the second scheme). 2. There is no need to add equipment at home, just set the phone number or SMS notification number that needs alarm in the front-end host. Once the probe triggers the alarm, the front-end alarm host can send alarm information or telephone notification to your mobile phone via SMS or telephone.
