Video, Audio & Camera
For vehicles equipped with cameras, the Traqcare mobile app provides live video streaming, audio monitoring, two-way intercom, video history management, AI alert evidence playback, and device image gallery.
Camera features are only available for devices with a camera sensor configured. If you do not see the camera icons on your vehicle, contact your administrator to set up the camera sensor in Device Management > Camera Settings.
