The new models of mobile alarms have been improved on many points and are therefore suitable for even more applications. For example, the battery life has been drastically improved and the setting has been greatly simplified by using an APP. There are 3 models of mobile phone alarms that can all run on battery standalone for several months. The first model is a PIR motion sensor with a built-in GSM module which sends an SMS when there is an alarm. In the second model, the GSM module is built into a magnetic door contact. With the third model, the GSM module is also built into a PIR motion detector, but it also has a camera so that an e-mail is sent to the set e-mail address in addition to an SMS.
