signal. Traditional CCTV monitors can now be replaced by any display unit with VGA input. The BNC to
VGA Converter is compact and can be mounted nearly anywhere including on the VESA mount found on
most VGA monitors. SECO-LARM BNC to VGA Converters come in basic and high resolution models.
The SECO-LARM VGA to BNC converter converts your VGA signal to be viewed on any TV, projector,
or other viewing device that uses standard BNC connector while also viewing it on a VGA monitor.
