This VGA Wall Plate Cat5 Video with Audio Extender kit includes both transmitter and receiver units, allowing you to make out-of-the-way connections from a VGA video and audio source to a remote monitor location. The transmitter and receiver wall plates can be placed in a wall or ceiling gang for a cleaner, more professional VGA installation, supporting connection distances up to a maximum of 300m (950ft) would highly recommend this to anyone or any business looking for an easy and more efficient way to present; bayreviews.com Offering maximum versatility and convenience, the VGA wall plate kit is easy to install; simply wall mount the transmitter unit near the intended VGA source, then wall mount the receiver unit near the monitor/projector. The VGA transmitter and receiver units can then be linked using standard Cat5e or Cat6 cable to provide a high quality video and stereo audio extension while concealing the cable for a neatly placed installation. Both VGA transmitter and receiver units use a 12V DC terminal block connector behind the unit that offers a more secure and economical installation; using Cat5/Cat6 cable to extend the VGA signal offers a cost-effective solution based on the broad availability of networking cable which is far more flexible than VGA cable, not to mention less expensive. Unlike some video extension systems, our VGA extender wall plates also allow you to make use of an existing networking cable (Cat5, Cat6) infrastructure, eliminating the need to re-run cable in the event of an upgrade from VGA to another video standard, by simply swapping out the wall plates.
