sure the wire connection have the same polarity on both the transmitter and receiver.
d. Connect a coaxial cable with BNC connectors between the ST-CCTV-VBAC-RX’s
BNC port and the receiving device (e.g., display, DVR recorder).
e. Connect an ST-PS12VDC1A 12V DC power supply to the ST-CCTV-VBAC-TX and
another ST-PS12VDC1A power supply to the ST-CCTV-VBAC-RX. Connect each
supply to an AC outlet. An LED on each unit will display a green light indicating the
transmitter / receiver is powered.
Settings
a. The ST-CCTV-VBAC-TX will require gain adjustment consistent with cable distance.
Use the following as a reference guide for setting the transmitter’s Gain Control per
distance.
b. Use the ST-CCTV-VBAC-RX’s brightness control to adjust the required brightness
level.
c. Image sharpness may be affected with the length of the transmission cable. The
ST-CCTV-VBAC-RX’s Sharpness Control can be used to achieve the best image
sharpness. Refer to the reference guide below to set the sharpness control’s DIP
switches per cable distance.

5. TROUBLESHOOTING
a. Make sure all component and UTP cable connections are tight and not loose.
b. Ensure the wire connections on the transmitter and receiver are using the same
polarities.
c. The quality of UTP cables has a major effect on the usable distance of transmission
lines and the quality of the displayed signal. Therefore, the actual transmission length
is subject to the quality of the UTP cables being used. Professional grade
transmission lines cables should be used.
d. If your device is not displaying a video signal check to be sure the transmitter and
receiver each have power. Then check all wire connections for tight fit and correct
polarity.
e. If interference appears on the image check all system connections including camera,
housing, monitor, DVR, etc. as well as ensuring all devices are property grounded.
