    Kramer 4X1VB reviews

    4X1VB Mechanical Video Switcher, 4x1 (BNC) is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Easy, inexpensive, and reliable I'm using the video switcher to capture lectures and classroom sessions when we have 2-4 cameras in use. The switcher is quick, small, and easy to operate. The only downside is that break-before-make (BBM) switching can cause a *blink* between channel transitions, but it is very short and we can accept this given the price of the product and audience for our videos.
    Date published: 2010-11-11
    Rated 2 out of 5 by from Decent, not for high quality usage This would work when I only had 2 BNC cables going in to it from a hdx900 HD camera. When I plugged in a third input it would scramble that monitor and cause a delay and occasional static in the other two inputs. I tried to see if it was just that input or cable, but it was not. It would only cause this problem when I plugged in ANY third input.

    Rated 4 out of 5 by from Great Product perfect for the application and size.
