Thanks Dan, 6 cameras installed (DS-2CD2347G2-LSU/SL), image appears fine until motion triggered, have noticed sometimes the iframe keeps defaulting to 1 rather than the default 50. Keep changing but reverts back.
Installed Baseline Firmware_NVR (76/77/86NI-E)_En_V3.3.0_build150328(new) on Saturday, now Set Alarm Notification won't switch on. Anybody else having this issue?
