ALI-AV3 HD Video/Power Balun 

Quick Start Guide

The ALI-AV3 HD Video / Power Baluns adapt HD-CVI/TVI/AHD video signals on coax and 12/24 V power to an RJ-45 connectorized interface 
for transmission across standard Cat 5e/6 UTP cable. These baluns are ideal for transmitting power to and video signals from an HD video 
camera and an HD video recorder through Ethernet cable instead of more expensive RG-6 coax/power cable. Features include: 

• 

Transmit HD-CVI/TVI/AHD video and power over one CAT5e/6 UTP cable

• 

Includes 2 units: 1 x RJ-45 to BNC with DC power plug, 1 x RJ-45 to BNC with DC power jack

• 

Carries 300 mA at 12 Vdc / 24 Vac up to 655 ft 

• 

Built-in ESD, EFT (impulse noise) and transient protection

•
