Experiments have been conducted comparing the traditional wired system and video analytics in the "ventilation-controlled" and "load-controlled" modes. It has been established that the wired system works faster with PRV, and with PRN, the video detector is faster in reaction speed. For each mode of gas exchange, the concentration of carbon monoxide is determined, and it is also established that the response time occurs before reaching deadly concentrations of carbon monoxide, as well as concentrations that can cause irreversible effects in the body. The conclusion is given on the complementary use of a fire alarm and a fire detector with a video channel to increase the reliability and efficiency of fire detection, as well as recommendations for calibrating thresholds and filtering false alarms. Special attention is paid to the practical aspects of integrating video detectors into existing fire safety systems, especially in facilities with high thermal stress and the risk of rapid fire development. Approaches to adaptation of IPV trigger thresholds are proposed in conditions of low smoke and insufficient illumination to minimize detection delays. Experiments confirm the expediency of combining both methods to ensure maximum protection in the early stages of a fire
