What is an EVENT file?
An .EVENT file is a data file that stores records of specific occurrences, actions, or triggers. Because the .EVENT extension is generic, it has multiple possible meanings. It is commonly used by security camera systems, like Hikvision DVR and NVR devices, to log motion detection or system events. Dashcams, such as those made by VIOFO, also use .EVENT files to mark important video recordings, like hard braking or collisions.
Additionally, the European Data Format (EDF) uses .EVENT files to store annotations for medical biosignal data. Software applications sometimes use it as a generic log file, often formatted in JSON. Historically, it was also used as a Corel Cataloged Folder File by older Corel software.
How to open EVENT files?
You can often open plain text or JSON based .EVENT files using a standard text editor like Notepad++ or Visual Studio Code. However, if the file comes from a security camera, dashcam, or medical equipment, it might use a proprietary binary format. For security systems, you usually need the manufacturer's proprietary viewer, such as the Hikvision VSPlayer. Dashcam files are typically accessed through the dashcam's mobile app or desktop player.
Inspecting EVENT files online
Because an .EVENT file can be many different things, it is hard to know which software you actually need. viewer.online/event can analyze .EVENT files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
In conclusion, viewer.online/event is useful for identifying, inspecting, and understanding .EVENT files without installing software or dealing with compatibility problems. It helps you quickly determine the true source of your file.
