This camera is great for deep tanks as the zoom lens allows you to focus on the bottom of the tank and see exactly what's happening. The zoom lens offers a 42 degrees horizontal field of view. It gives you one of the tightest views available and allows the operator to see further back in great detail. Great as a rear-view camera and for large carts. The outdoor nightime viewing distance is 10m (30'). The white light camera option gives you full color in all lighting conditions.
