Axis Camera SupportGarmin offers support for select axis cameras, which can be used for surveillance and situational awareness on vessels of any size. Our integration allows you to view video on every screen on your boat and, if you wish, view multiple streams on the same screen. You can control your camera’s pinch-to-zoom and pan/tilt settings with gestures directly on the plotter screen. Use an Axis encoder to convert analog camera, such as Garmin GC 10, to video over IP. AXIS and FLIR Camera SupportGarmin offers support for select axis cameras, and for select FLIR cameras. These can be used for surveillance and situational awareness on vessels of any size. You can control your camera’s pinch-to-zoom and pan/tilt settings with gestures directly on the plotter screen and view video on multiple screens as well as multiple video streams on the same screen. Use an Axis encoder to convert analog camera, such as Garmin GC 10, to video over IP Catch All the Action On the WaterThis chartplotter supports wireless connections to Garmin VIRB action cameras so you can catch all the action during your time on the water. More importantly, with a simple software update, you can control recordings, take still pictures, and stream video from a VIRB action camera to your GPSMAP® 7400 series chartplotter or 8000/8400 series Glass Helm chartplotter. In fact, you can stream video from up to 4 VIRB action cameras and view the video on a compatible marine chartplotter. You can even view previously captured images and videos on the chartplotter and display thumbnail previews for easy selection. Control play, pause, seek and replay from your chartplotter. There’s even an automatic slide show mode and the ability to delete unwanted VIRB images or videos. Each VIRB can be named for easy identification. You can also control your VIRB cameras to change VIRB video settings, including aspect ratio, video resolution, frames per second, photo size, field of view and more — directly from the marine chartplotter. Send NMEA 2000 boat information from the chartplotter to VIRB to be overlaid as G-Metrix™ data on the video using VIRB Edit or the VIRB mobile app. Some data requires optional accessories.
