Quick answers about the DS-2PA1205-DGA, and how it compares.
How do I choose the right power supply?
Add up the power of every camera on the supply: use the maximum watts (or amps at 12 V) from each camera datasheet, and keep about 20% spare. Check the voltage too: 12 V cameras need a 12 V supply, 36 V devices need 36 V. On long cable runs use thicker wire, so the voltage at the camera does not drop. Not sure?
