Sorry, Yeah I am currently running 201606201315 but have tried IPNC S2l2.0.1_build201607221508 previously with no luck.
See here for other firmware v2:

if both ip cam have the same ip can be a conflict between them.
trying in turn only one IP cam.
connects only one IP cam and check in SADP,
then connect the other,and check in SADP (but first ip cam must be of).
