[SML] video camera setup for video monitoring stage from the obstructed booth

[Robert Engel]

Steven,
With this type of security camera you would have to make sure to switch the
output from the HD over Analog types (TVI, AHD, CVI) to standard CVBS /
Composite video.  Doing this will lose any type of higher resolution
(1080P, etc), but should work. (That specific camera doesn't really say it
outputs normal video - so that one may or may not work.)
Or.. you could use the HD over Analog types to get a beter picture with the
use of a converter like the one below that would convert the TVI into VGA
that can be shown on a monitor at the higher resolutions that the camera
can output - Still with the camera -> BNC (coax) -> converter -> VGA ->
monitor.
