aPPlications

Video Distribution between disparate systems often

results in the degradation of image quality, especially

if the method used is to bridge through multiple

pieces of equipment. This becomes a particular

problem in modern systems when you think about

the number of units that may need to be connected

onto the video signal, such as a matrix, DVR,

multiplexer, video analysis unit, display wall etc.

With Meyertech’s ZoneVu VDA unit however, up

to four separate modules of video processing

equipment can be run on the same video signal,

each receiving the best possible quality signal

and without the threat that an issue with one

item could cause loss of video system wide.

Each video distribution channel on the VDA is

independent and with only four channels per PCB

card within the unit maximum reliability is ensured

with minimum impact on the system should the

worst happen, and to protect against every possible

worst case scenario the unit is tted as standard

with output short circuit protection and has the

option of being supplied with a dual redundant

power supply unit capable of powering two VDA’s.

The ZVP-VDA321-4 is also capable of being used

as a video line receiver. Many modern digital units

cannot cope effectively in situations where, due to for

example the distances involved in image transmission

from the video source, the video signal drops short

of the standard 1V peak to peak normally required

for video processing. This can mean blank or blue

screens on displays or vital information to be missed

off recordings, all of which can be prevented by the

addition of the ZoneVu VDA unit which can monitor

the signal strength and automatically increase

the Gain control should the level prove too low.
