PSTN alarm system &  gsm alarm system

1.Public switched telephone network. Basically the normal phone network, or land line.
GSM stands for Global System for Mobile Communications, which is basically the mobile phone network as we know it.
2.pstn alarm system no need sim card (2g sim card), gsm alarm system is wireless, need sim card (2g sim card).
3.pstn alarm system can be use with wireless & wired sensors, the same to gsm alarm systems.
4. GSM now provides a viable cost alternative to traditional 'land-lines' and the popularity of the networks is testament to the quality of service, coverage and value for money provided. 
Now we recommend the gsm alarm system or Dual-Network Alarm System, the quanlity will be much stable
