Q・I‘ s products range from cameras for deep-sea exploration mounted on “SHINKAI 2000” in the past to camera robots used in Fukushima Daiichi Nuclear Power plant recently. FM-4100 and FM-2100, which are Japanese suspended ultra-compact underwater color TV cameras, are produced based on the Q・I‘ technology. They show their true ability in a wide range of fields from underwater observation to deep-sea exploration as well as being easy to use.
These cameras are best for customers who want to
“explore underwater to find out something there” and
“find schools of fish with switches while looking at a controller screen without moving the camera”
Q・I’s underwater cameras provide complete control and easy operation with switches on the controller. They are proven to have enough durability by hydraulic testing. Of course, repair service is available for a fee.
