Table B. Wiring Distances for 5 VA Cameras (24 VAC/12 VDC)
The following are the recommended maximum distances for low voltage cameras. These distances are calculated
with a 10 percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for AC-powered
devices.)
EXAMPLE: A camera that requires 5 VA and is installed 224 feet (68 m) from the transformer would require
a minimum wire gauge of 24 AWG.
