found the power specs

Dietmar, trying to debug on of the security cameras, asked me again for power specifications. And, once again, there was nothing I could do. At home, anyway. I did not have a camera nor a power supply. But, suddenly, I realised I could get someone at the CAO to check for me. Tim helped by unplugging one of the current supplies. 12 VDC, 1 A, centre positive.
