I'm sure this is not ideal but this system grew beyond what I originally planned. I have four cameras on one dvr toward the front of the house and another four on another dvr hooked to the same router. An 8 camera dvr would have been better but it would have required more wiring. Anyhow, this is what happens. All 8 cameras show up on remote viewing but they cycle randomly. I just wondered if anyone could explain why they cycle as they do and if there is a way to control the cycling. In other words, is there a way to trigger the front or the rear sets or am I just to wait for the next cycle.
