PACKAGE CONTENTS
This package contains:
One ST-CCTV-VBACT-POEPTZ Active Video Transmitter
One ST-CCTV-VBACR-POEPTZ Active Video Receiver
One installation manual
Note: A DC power supply is required. Selection of a power supply with the correct voltage and
ampere rating is determined by the voltage drop for the specific length of UTP cable used between
the transmitter and receiver. Consult your UTP cable manufacturer’s specifications to determine
the voltage drop.
PRODUCT DESCRIPTION
The ST-CCTV-VBAC-POEPTZ Active Video Balun Transceiver allows the transmission of
real-time video and power over Unshielded Twisted Pair (UTP). The ST-CCTV-VBACT-POEPTZ
video transmitter converts an unbalanced video signal to a balanced signal transmitted over UTP.
The ST-CCTV-VBACR-POEPTZ video receiver then converts the balanced video signal to an
unbalanced signal for display on the device. These units offer excellent common mode and
multi-channel interference rejection and the transmission and display of high quality color video for
security, surveillance, video conferencing, video distribution and PTZ control signal applications.
The ST-CCTV-VBAC-POEPTZ also transmits electrical power along with data to remote devices
over standard UTP cable. In applications such as security surveillance and elevator surveillance
the Power Over Ethernet (POE) feature allows the UTP cable to replace power, video coaxial and
data cables making system installations easier, faster and less expensive without building
remodeling.

INSTALLATION AND OPERATION
1. UNPACKING and HANDLING
Each unit is shipped assembled and factory tested.
Ensure that all accessories are removed from the container before discarding packing material
2. MECHANICAL INSPECTION
Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is
clean, and no connectors are broken, damaged, or loose. If equipment appears to be
damaged or defective please contact your distributor or SecurityTronix in the USA at
1-610-429-1511 for assistance.

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

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, data and UTP cable connections are tight and not loose.
b. Ensure the UTP wire connections on the transmitter and receiver are using the same
pins and the data wires the correct 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 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.
f. If the image appears twisted or wobbly make sure the wire connections on the
transmitter and receiver have the same polarities. Also check the UTP cable
connections to the RJ45 connectors are in the correct order.
g. If the image is too bright the received signal may be too strong and require adjustment
using the ST-CCTV-VBACR-POE’s Brightness Control and Sharpness Control. It may
also be necessary to adjust the ST-CCTV-VBAT-POE’s gain control.
h. If the remote CCTV camera cannot be powered by the ST-CCTV-VBACT-POE
transmitter (i) check the power to the remote camera and determine what the voltage
level is at the camera, (ii) check the input voltage to the ST-CCTV-VBACR-POE
receiver to see whether it is in the required range, (iii) recalculate the voltage drop
from the receiver to the camera for the length/gauge of UTP cable being used –the
voltage drop together with an “undersized” power supply will keep sufficient power
from arriving at the camera, (iv) make sure the wiring of the UTP cable to the RJ45
plugs is in the appropriate order, and/or (v) shut down the camera’s power, disconnect
power to the camera and reconnect/re-energize to make sure the
ST-CCTV-VBAC-POE is not in overload protection status.
i. If power is getting to the remote camera but PTZ controls are not functioning correctly
(i) make sure the 2-wire UTP data cables have tight connections at the remote
camera, transmitter, receiver and controller and (ii) ensure the polarities for the 2 UTP
data wires are consistent among the remote camera, transmitter, receiver and
controller connections.
