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.
