Old Post, 24 volts draws half of what 12 volt does. Can get more power through small conductors with 24 Volts. Cameras are Simular(12 and/or 24 volts and may be AC and/or DC.
12 Volts is great as you can easily Back Security/Cameras, Many Electronics with a 12 Volt Battery. Can use a Car Battery to give Alarm System large backup times after a Hurricane, or during an Extended Power outage. AC or DC should be a question. With AC, You would need an Inverter. Best to Stay at 12, as any converting/inverting, their is a loss.
