Introduction:
The ENFORCER EVT-AH16-VT2Q Rack-Mount 16-Channel Active Video Balun
Hub allows up to 16 color or monochrome CCTV cameras to be connected via
inexpensive CAT5e/6 unshielded twisted pair (UTP) cable to a DVR, video
switcher, or multiplexer. It cuts the cost and complexity of security networks by
eliminating the need to run expensive coaxial cable to multiple CCTV cameras
while transmitting color video signals up to 5,000ft (1.5km).
Features:
Compact 1U height fits most standard 19” equipment racks.
16 video inputs and 16 video outputs with 16 local loop out.
Active operation amplifies the video signal for excellent picture quality at
long distances.
Transmits color video signal up to 5,000ft (1.5km) using an active balun
transmitter and 3,940ft (1.2km) using a passive balun.
Uses low-cost Cat5e/6 unshielded twisted pair cable instead of costly
coaxial cable.
Adjustable contrast and brightness at each port.
Built-in video surge protection.
Blue LED at each port indicates video signal.
Power LED indicates whether the unit is powered.
Includes one 1.5A@12VDC adapter.
Gold-plated BNC connector.
Easy installation: Removable terminal blocks.
Perfect for use with DVRs.

Wiring:
1. Connect the included 12VDC adapter to the EVT-AH16-VT2Q and to a power source.
2. Run a Cat 5e/6 UTP cable from each camera through the wall or through a conduit to
the EVT-AH16-VT2Q.
Note: If existing telecom or data UTP cables are available, they can be mixed and
matched with new cables. Running two or more cables together should not
affect the video signals.
3. Connect a video balun (use active transmitter for best results) to a pair of wires in the
UTP cable near the CCTV camera, and then plug the video balun into the camera.
Connect the matching pair of wires in the cable at the other end of the correct video-in
port on the back of the EVT-AH16-VT2Q.
Connecting to DVR, Video Switcher, or Multiplexer:
1. Run one coaxial cable (not included) from the Video Out or Video Loop port on the EVT-
AH16-VT2Q and connect it to the corresponding video-in port of the DVR, video
switcher, or multiplexer (not included).
2. Repeat the above as necessary until each used channel is connected to the DVR, video
switcher, or multiplexer.
