With cameras you have to buy with a proper understanding that they're not going to last that long. I've had homebrew stuff for over 10 years. I've got about 8-9 units right now. They're good units but things happen on electrical stuff that gets left out in the weather. It is frustrating to no end at times but thats just the nature of it. The good thing is that with the home built they are fixable whether its the camera or the board or whatever.
