Bi-directional digital telemetry communication system gives full control over video functions and ensures maximum flexibility. The intensity of the LED lights can be controlled from surface to achieve the best illumination condition. Both side-view and down-view are controllable from surface.

Side-view is for checking the detailed images of the well wall, and down-view will provide a full image of the hole.

The KATEYE ™ Downhole Video has dedicated lens which has a wide range of depth of field. It also has a big view of angle up to 120 degree; the side-view lens can be rotated with 360 degrees to cover the entire well walls. So you can see the corrosion or cracks, and it will provide you with a clear picture of casing wall.

The KATEYE ™ Downhole Video has equipped one of the world fastest telemetry modules, and make sure the picture has the best quality and refreshing rate compare with competitors.
