Works well with an 8Ch NVR (NVR8-8580) - My other cameras are the 885/886 Variety and they do not support facial recognition - this 887 does. So if that is of interest then you do want this unit. The spot light and speaker are a nice to have - specially the light for me. This is no different to the 885F in terms of functionality. Other difference i could spot was the 885 supports three video streams Main/Sub/Mobile but this 887 only supports Main/Sub. Remote view over cellular network with Homesafe view (average piece of software IMO) seems to work either way.
