What It Is
The ENFORCER EVT-PC8-VTDQ is a 8-port PCI Video Balun Hub specifically designed for PC based DVR cards. The
EVT-PC8-VTDQ 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
screwless terminal block for convenient and organized wiring installations.
The EVT-PC8P-JTQ is an add-on power distribution card for EVT-PC8-VTDQ. When installed with EVT-PC8-VTDQ 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 supply of CCTV cameras.
Installation
Installing the EVT-PC8-VTDQ and EVT-PC8P-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-PC8-VTDQ and/or EVT-PC8P-JTQ in their respective slots with the provided screw at the back panel
of the computer. Please note that the EVT-PC8-VTDQ and EVT-PC8P-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-PC8-VTDQ and EVT-PC8P-JTQ, be installed
adjacent to each other as shown on Fig. 2.
EVT-PC8-VTDQ 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: a. Individual separate passive video baluns such as SECO-LARM’s EVT-PB1Q are required for each camera on the
camera side (not included).
b. 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.
c. 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-PC8-VTDQ can accomodate a maximum of 8 cameras.
d. Connect the other ends of the UTP cables of the respective cameras into the screwless terminal block on
the EVT-PC8-VTDQ 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 of channel 1.
NOTE: Bare wires must not be exposed outside of the EVT-PC8-VTDQ’s terminal block.
