1970s Sony HVS-2000P camera selector & effects unit
This is a Sony HVS-2000P camera selector/effects unit from the late 1970s. I got this unit with the B&W Sony HVM-100CE camera. This unit works good and I use it to operate my HVM-100CE camera. With this unit you can pretty much switch between 2 cameras and use transition and chromakey effects as well.
