VPD (Video/Power/Data) Combiners
Manual
ENFORCER VPD (Video/Power/Data) Combiners work in conjunction with standard passive
VPD baluns and RJ45 cables to simplify and organize a large scale CCTV installation. Using this
allows for increased flexibility and simplified, more organized cable installation, providing power to
cameras while delivering high quality video all over a single CAT5e/6 cable. Troubleshooting is
therefore greatly simplified and clutter reduced. ENFORCER VPD Combiners are compatible with
all HD analog, including HD-AHD, HD-CVI, and HD-TVI, as well as traditional analog formats.

All ENFORCER VPD Combiners are capable of transmitting the various HD Analog formats such
as HD-AHD, HD-CVI, or HD-TVI. These formats are supported in addition to traditional analog
formats.
ENFORCER VPD Passive Midpoint Combiners are typically installed between the camera and
DVR combining data, video, and camera power via CAT5e/6 cable to simplify installation and allow
for easy expandability and serviceability. The passive combiner allows for the use of any external
ENFORCER low voltage power supply or a compatible third party low voltage power supply.
ENFORCER VPD Active Midpoint Combiners provide the same benefits as the Passive Midpoint
Combiners, but include either an integrated 12VDC or 24VAC (for greater distances) power supply.
ENFORCER VPD Passive Endpoint Combiners are typically installed near the DVR and include
BNC connectors to connect directly to the DVR. This combines data, video, and camera power via
CAT5e/6 cable to simplify installation and allow for easy expandability and serviceability. The
passive combiner allows for the use of any external ENFORCER low voltage power supply or a
compatible third party low voltage power supply.
ENFORCER VPD Active Endpoint Combiners provide the same benefits as the Passive
Endpoint Combiners, but include either an integrated 12VDC or 24VAC (for greater distances)
power supply.
All 16 channel versions are rack mountable or wall/desk mountable.
IMPORTANT: Only low voltage power supplies may be used.

1. Location: Install the unit in a ventilated, dry location where it will not be disturbed by other
activities. A data center room is ideal.
NOTE: For indoor use only. Make sure there is a cool air flow around the unit to prevent it from
overheating.
a. Install the Passive Midpoint VPD Combiners near the power supply at a point between
the cameras and DVR.
b. Install the Active Midpoint VPD Combiners at a point between the cameras and DVR. A
power supply is already included in these models.
c. Install the Passive Endpoint VPD Combiners near the power supply and DVR – ideally in
the same room.
d. Install the Active Endpoint VPD Combiners near the DVR – ideally in the same room. A
power supply is already included in these models.
2. Mounting:
a. Wall-mounting – attach the two included mounting brackets to the sides of the VPD
Combiner (see fig. 1). Then attach to a wall with the four included screws and, if needed,
optional screw anchors.
b. Rack-mounting – attach the two included mounting brackets to the front or back of the VPD
Combiner (see fig. 2). Then attach to a standard 19” rack with the four included screws.
NOTE: Rack-mounting is available for 16-channel models only.

ENFORCER VPD Combiners
Wiring the Passive Midpoint VPD Combiners
(EB-P304-01MQ and EB-P316-60MQ):
1. Connect cameras to VPD baluns (such as the EB-P101-20VQ) and run them via CAT5e/6 to
the “Camera” ports on the VPD Combiner.
2. Run 12 or 24 VDC power to the “Power In” press-fit terminals on the VPD Combiner,
depending on each camera’s power requirements. For each camera port connected to the VPD
balun, the corresponding power input must be connected to power.
NOTE: Observe polarity when connecting power.
3. Run a CAT5e/6 cable from the “Video Out” port on the VPD Combiner to baluns or a multiple-
channel passive video transceiver on the DVR side.
NOTE: Consult the balun or video transceiver manual for range information.
4. Run a CAT5e/6 cable from the “Data Out” port on the VPD Combiner to the DVR or PTZ
Controller.
Sample Installation:
NOTE: EB-P304-01MQ shown. EB-P316-60MQ has similar connections, but has 16 channels.

Wavy or ghost image if connected to
image processor (e.g., multiplexer or
DVR), but not if directly to monitor.
Move the Cat5e/6 cable away from possible sources of interference.
Ensure that the same twisted pair connects to a balun at both ends of the
cable.
Replace the cable with a new Cat5e/6 cable.
Image is wavy and shakes.
Try reversing polarity of the two wires at one end of the Cat5e/6 cable.
Reduce the Cat5e/6 cable length.
Replace with a higher-grade cable. Cat5e cable meets the specifications
in the manual. Cat6 cable allows longer range.
Double-check that the Cat5e/6 and BNC cables are connected properly.
Run a continuity test on all wires in the cable.
Check that the camera and monitor are powered up.
PTZ Controls do not work.
Reduce the Cat5e/6 cable length.
Refer to your PTZ camera manual.
Check that the power supply is ON.
