When I bought the original setup, I received the power supply 24VAC-20VA, but i did not order the enclosures at that time. After I finished testing the cameras and was satisfied i ordered the enclosures.
I noticed that they have the AC2420 which I received, but they also have one called the AC2440 ( I assume 24VAC-40VA), I guess it is possible that with the enclosure added I need the more powerful one (AC2440) and the salesman just missed that I had the smaller version?
Once again, thanks for your help.
