        abstract = {In this report, an IoT, based lift surveillance and security system is introduced to improve elevator safety by observing both the external and internal conditions of the elevator in real, time. The innovative system combines various vital sensing devices that include thermometers, hygrometers, air quality sensors, smoke sensors, tilting switches, and audio pick, ups into one smart module that uses an ESP32 chip for efficient information gathering and analysis. An efficient MQTT messaging protocol allows the quick and reliable wireless data transfer between the embedded system and a Python, based GUI application. The GUI application supports the remote control of the motors to simulate lifting motions, warns users instantly about life, threatening situations, and presents real, time graphical representations of the data acquired from the sensors. The energy held in the rechargeable lithium; ion battery allows the system to work continuously even in the absence of electricity. The experiment has confirmed that the proposed remote monitoring method guarantees the accuracy of data, fast data transfer, and effective detection of threats. Based on the proof, this approach is a low, cost solution that is highly flexible in accommodating different sizes of buildings, especially for small office spaces and apartment buildings.},
