• The maximum cable extension is 300 feet (91 meters) for video resolutions
i and below.
• The maximum cable extension is 150 feet (45 meters) for video resolutions
•If EMI is present anywhere near the RJ-45 video cable runs, it ma

• Extensions under 130 feet can use Auto EQ (which is on by default).
Extensions over 130 feet will require you to manually EQ your signal (see

plices or use of punch down blocks.
igh quality CAT-6a cabling should be used for maximum performance.
• Do not use stranded or low/no skew cabling. Solid core cabling should be
sed for maximum performance.
