Arrived quickly. Well packaged. Initial install was relatively easy although adjusting direction of cameras needs 3 hands and two sets of eyes. Cameras were connected PoE and refresh rates are a bit slow at times. Channel selection is tricky. First camera connected to NVR initialises as channel one and can't be changed so channels don't necessarily align with ports on NVR so working out which camera is on which channel not straightforward. Camera connectors seem sensitive and keep dropping out with windy conditions so make sure connectors are in good order and sheilded from elements if outside. Can't get NVR to connect to our LAN and can't get app. to work either to this stage.
