Use the formula below to select the correct power supply for cameras connected in parallel (positive to positive, negative to negative):

Total current for a 24 VAC system:

TOTAL CURRENT = (202mA x total number of cameras) Example: 202mA x 5 total cameras = 1010mA

Note: 202mA is camera plus power supply

CAMERAS VOLTAGE CURRENT POWER

1 24 VAC/VDC 102mA 2.5W

2 24 VAC/VDC 210mA 5W

3 24 VAC/VDC 331mA 7.9W

4 24 VAC/VDC 487mA 10.9W

CABLE AND POWER GUIDELINES

This chart shows the proper current needed for power supplies for Q-View Series cameras. Use Class 2 Power only. Input voltage must be

24 VAC/VDC.

NOTE: The above table is based on a "worst-case" power supply. Using a regulated or switching power supply can increase your cable

distance. Videolarm recommends using our PS24 power supply, or a CSA/UL listed Class 2 power supply.
