Recently, the spread of video recording devices has increased, making it easy to see in our daily lives, and introducing them into fire investigations can provide information that is difficult to miss or identify in the field, so it can be useful. In the existing fire investigation technology, the main method was to analyze physical evidence such as burn patterns and debris and investigate the cause of the fire through eyewitness questions. However, It is a study on how to more accurately determine the ignition point and cause of the fire by using analysis technologies for images such as CCTV and black boxes collected at the fire site. Among the various image analysis techniques, the image compression analysis technique is a technique that can be easily applied, and as a result of experimenting and analyzing at various image reproduction speeds, it was confirmed that a certain double speed image compression helps the fire occurrence point and analysis.
