User mgraph220 mentions "ActiveHome", by which I assume he means the original AH for the CM11A, and the CM11A only supports delays in multiples of minutes.
It also appears that he wants to run his camera sequence repeatedly over (probably) a long period of time, so unless ActiveHome Pro can run macros in a continual loop, upgrading to a CM15A and ActiveHome Pro probably won't solve the problem - for one thing it'd be a bear to program a macro with 720 steps/hour times the number of hours.
I thought X-10 sold some software which would allow doing what he needs using the CM11A or a Firecracker/Transceiver combo, but I'm not enough into cameras to know what's available. And if the output from the cameras is only going directly into a recorder or TV, something like this would add needless complexity.
Depending on the operating system he is running there are probably alternative solutions using batch files.
