Installation Requirements
• For indoor applications, use Category 5 (or above) UTP
cabling approved for indoor use.
• For outdoor applications, shielded Category 5 (or above)
cabling should be used for all wired Ethernet connections
and should be grounded through the AC ground of the
power supply.
We recommend that you protect your networks from
harmful outdoor environments and destructive ESD events
with industrial‑grade, shielded Ethernet cable from Ubiquiti
