I have used D-Link cameras over 10 years.
DCS-936L worst ever. Repeated setup issues, if a power loss occurs it resets to defaults and loses time setting.
Refuses to allow browsers Firefox, Chrome or I.E. 11 to access it.
I have 6 other cameras online ranging from DCS-932L to DCS-5030L, if the DCS-936L locks up which it does regularly it bring down all the other cameras.
