WHAT IT IS

The ENFORCER EVT-PC4-VT2Q is a 4-port PCI Video Balun Hub specifically designed for PC based DVR cards . The
EVT-PC4-VT2Q is the most practical and cost efficient way of connecting video signals from CCTV cameras to PC
based DVR cards via Cat5 cables. It eliminates the need to install individual video baluns on the DVR card side, and is
equipped with a gold plated BNC connector for optimum video performance and a screwless terminal block for
convenient and organized wiring installations.

The EVT-PC4P-JTQ is an add-on power card for EVT-PC4-VT2Q. When installed with EVT-PC4-VT2Q it will allow power
to be transmitted from the PC side to CCTV camera side over the same UTP cables used by the video signal. It
centralizes the power suppy of CCTV cameras.

Installation
Installing the EVT-PC4-VT2Q and EVT-PC4P-JTQ

1. Shut down the computer, disconnect the power and remove the computer cover from its chasis. See Fig. 2.

2. Determine the location of the available card slots at the back panel of the computer, and remove the metal covering
of the desired slot.

3. Securely mount the EVT-PC4-VT2Q and/or EVT-PC4P-JTQ in their respective slots with the provided screw at the
back panel of the computer. Please note that the EVT-PC4-VT2Q and EVT-PC4P-JTQ boards do not need to be
inserted into the PCI (Peripheral Componet Interconnect) slots of the computer motherboard. Then replace the cover
of the computer.

NOTE: For convenient wiring it is recommended that the DVR cards, EVT-PC4-VT2Q and EVT-PC4P-JTQ, be installed

adjacent to each other as shown on Fig. 2.

EVT-PC4-VT2Q Wiring (see Fig. 3) - Video Balun Card

1. Make sure the maximum distance between the CCTV camera and the DVR card does not exceed 1,950 feet for
monochrome or 1,300 feet for color.

2. Run the UTP cable from the DVR card to where it will be connected to the CCTV camera. Follow the CCTV camera’s
wiring instructions for information on how to safely run and hide this wire.

NOTE: 1. Individual separate passive video baluns such as SECO-LARM’s EVT-PB1 are required for each camera on the

camera side.

2. The video baluns are polarity-sensitive. Take note of the colors of the positive & negative wires of the video
signal cables as this will be needed when connecting the other end of the UTP cables at the DVR card side.

3. Use the orange/ orange-white color wire pair of the UTP cable for the video signal. Connect the UTP cables
to the passive video baluns on the camera side and plug the video baluns into the BNC connector of the
CCTV cameras. The EVT-PC4-VT2Q can accomodate a maximum of 4 cameras.

4. Connect the other ends of the UTP cables of the respective cameras into the screwless terminal block on
the EVT-PC4-VT2Q side, see Fig. 3. Each video signal from the CCTV camera requires one positive and
one negative wire, so observe correct polarity when connecting the UTP cables. “Vi-1” represents the video
input and “Vo-1” represent video output of channel 1.

NOTE: Bare wires must not be exposed outside of the EVT-PC4-VT2Q’s terminal block.

5. Connect the included male-to-male BNC cable. Connect one end to the BNC female connector of the
EVT-PC4-VT2Q side and connect the other end to the BNC female connector of the DVR card side. Connect
as many cables as needed.

6. Test the connection by powering up the CCTV camera and DVR card to make sure they operate as expected.

EVT-PC4P-JTQ Wiring - Power Cord

1. When using EVT-PC4P-JTQ, the supplied 8-pin wire assembly must be first connected to the 8-pin connectors of both
EVT-PC4-VT2Q and EVT-PC4P-JTQ, which are located on their respective PC boards, before mounting them to the
computer chasis. Please see Fig. 1 & Fig. 5.

IMPORTANT – When using the EVT-PC4P-JTQ, the video signals from the CCTV cameras MUST be connected on
the terminal blocks of the EVT-PC4P-JTQ side and the video input terminal blocks of the EVT-PC4-VT2Q must not be
connected to any video signal. This means that when the EVT-PC4P-JTQ is used the video input must be connected
on the EVT-PC4P-JTQ side.

2. To minimized voltage drop, use two UTP wire pairs for power transmission. Use the spare blue/blue-white wire
pair and brown/brown-white wire pair of the UTP cable for 12 VDC power transmission. Connect one end of the UTP
cable to the EVT-PC4P-JTQ’s terminal block with “PWR’ marking. CORRECT POLARITY MUST BE OBSERVED.

3. Plug the included power adaptor into the power jack of the EVT-PC4P-JTQ and plug the power adaptor’s power cord
into the electrical outlet. Use on-board LED to verify polarity. See fig. 1.

4. Check the voltage reading at the end of the power line (camera side) to verify it is correct before connecting it to the
CCTV cameras.

WARNING: Using a voltage output in excess of the specified voltage level of a camera may cause damage.
