hi everybody im new to the forum
i have recently bought a ptz and im just not sure about the three wire power plug on my camera. The middle wire is ground and the two outside wires are 24v ac. Do i need two 24v connections to these two wires or is it a positive and negative. i have bought a transformer to run the camera but it doesnt really tell me anything either, it has two wires blue and red and doesnt tell me if they are both positive or positive and negative.
Any help really appreciated
