a. Connect the video source (e.g., security camera) to the ST-CCTV-VBACT-POE’s
BNC port using coaxial cable with BNC connectors.
b. If the video source requires power connect the ST-CCTV-VBACT-POE’s power lead
to the source. Many CCTV cameras are 12V DC.
c. Connect the ST-CCTV-VBACT-POE transmitter and ST-CCTV-VBACR-POE receiver
together using UTP cable between the transmitter’s and receiver’s RJ45 jacks. The
diagram below specifies required wire/pin positions.

d. Connect two wires of a UTP cable from the ST-CCTV-VBACT-POE’s Data wire block
to the remote CCTV camera. Make note which color wire is connected to the wire
block’s polarity. You will need to ensure the same wires and polarities are connected
to the camera and the ST-CCTV-VBACR-POE’s Data wire block.
e. Connect two wires from another UTP cable to the ST-CCTV-VBACR-POE’s Data wire
block to the remote CCTV camera’s controller (e.g., joy stick). Again, make sure the
wire connections have the same polarity on the transmitter, receiver and camera.
f. Connect a coaxial cable with BNC connectors between the ST-CCTV-VBACR-POE’s
BNC port and the receiving device (e.g., display, DVR recorder).
g. Connect an appropriately rated DC power supply to the ST-CCTV-VBACR-POE’s
power jack.
NOTE: The ST-CCTV-VBACR-POE requires more than 12V DC to
deliver power to a remote device (e.g., CCTV camera). However, power losses
will occur depending on the length and gauge of the UTP cable connecting the
transmitter and receiver. Therefore, before selecting a power supply you must
determine the amount of voltage drop for your particular length/gauge of UTP
cable and add that amount (voltage drop) back in to the required power supply
voltage. As UTP cable specifications vary, you must refer to the manufacturer’s
specifications for the UTP cable being used.
h. Connect the power 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-VBACT-POE 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-VBACR-POE’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-VBACR-POE’s Sharpness Control can be used to achieve the best image
