Sounds like I need to re-evaluate my situation and/or my equipment. Most of the local "pros" around here aren't really worth their salt, which is why I wanted to try myself. I've had a couple of different contractors out there, but didn't get a lot of help. The outfit who installed my system initially has been a disappointment in their customer service as well as their ridiculous prices. Disadvantages of a small town. I'm sure there's a way...cameras go out all the time, right? At any rate, thanks for the replies and the advice. I'm sure I will be posting again in the near future.
