I've only been using the ninja pan & tilts for a couple of years now!
I had only one problem with them thus far, and think it was heat related as the ninja stopped responding!(moved it to another location and haven't had it act up since)
I have them located under eves to limit their exposer to the elements!
I do have one wide eye cam but find the standard x10 color cams to have a slightly better pic, and mounted on a ninja I can get a wider viewing angle!
I have one in the back yard and have the 4 presets configured (realy only need three)
I can scan between this presets or focus on just one of the setting!
Could be set to motion sensors set in that preset viewing area!
