Home   8-Channel Active Video Balun Receiver
Model: VBAU800R

The VBAU800R-1U is an eight channel active device that allows reception of real-time monochrome (B&W) or color video using Unshielded Twisted Pair (UTP) cable. The unit receives eight channels of video from transmitter with both RJ45 and screw terminals that’s available for connections and provides eight pairs of BNC video outputs.

The unit is compatible with active transmitter (e.g. VBAU100T) and passive transceivers (e.g. VBU100T, VBU400T) with transmission distance up to 1200M / 4000Ft and 600M / 2000Ft respectively. Each switch can be independently adjusted for the different transmission distances and image quality based upon the type and quality of the cable being used. Housed in a standard 1U structure, VBAU800R-1U is rack mountable and excellent for large surveillance system installation.

Troubleshooting:

All transmission distances mentioned above are without connecting image processors (e.g. Quad, Multiplexer, or DVR). The transmission range would be reduced to 100~200M / 300~600Ft upon different camera, cable, DVR, etc.

These products are designed for long range transmission, utilizing the built-in video amplifier function. If your transmission range is under 100M / 300Ft, setting the video gain function too high will result in snowy, wavy, or overly bright images. It is recommended that this product be used for long transmission distances over 100M / 300Ft. For shorter distances use an alternate passive video transceiver such as the VB100S or VB100T series.

The active receiver has a switch with 4 different distance ranges for the range of transmissions. Please switch to the appropriate range upon your application to avoid any weak or bad image.

OKINA USA Cabling Systems and Solutions provides an answer for all your cabling needs. Our complete line of baluns allows you to easily extend your current audio/video/data system up to 1200ft and even up to 8000 ft, with an active balun.

OKINA USA Baluns are perfectly suited for applications such as these:
CCTV Security Systems
CCTV Surveillance Systems
CCTV Cameras
Home Theatre
LCD/CRT Monitors
Televisions
VGA Monitors
DVD Players
PCs (Personal Computers)
Laptops/Notebooks
USB and PS/2 Devices
UTP (Unshielded Twisted Pair Cable)
BNC (Coaxial Cable)

How does a balun work?
Baluns are used to convert between "Balanced and Unbalanced" electrical signals.
Baluns work by transforming the original unbalanced (video/power/data/etc) signal to a balanced frequency used by a different cable, like CAT5 UTP. Not only does this reduce interference, but it also allows you to transmit a signal much longer than the original application would allow. Baluns are always utilized in pairs. One balun is needed to convert the original signal to a new frequency, and another balun is used at the other end to revert to the original frequency.

"Passive" Video Baluns do not require power, and can extend a signal up to 2000ft (B/W)
"Active" Video Baluns require power, but can extend a signal up to 8000ft (B/W)
