Will update to 4 stars when they fix it. Not sure whats going on but it crashes immediately after connection. Same problem across two iPhones and an iPad - local or LTE.
- old review below -
This has been the ultimate solution for my home security needs. I had a previous camera set-up in place using a number of d-link day/night cameras (932L/942L) and was using another camera solution previously that didnt work nearly as well for streaming (the previous did not record video on movement and the stream quality was poor).
This one provides remarkably high quality recordings and views fluidly. Lots of set-up options that really work well with a variety of cameras.
From an app perspective Id like to see push notifications, which Im not uncertain you cant set up somehow - since synology servers probably can do that already.
The only downside is the license cost for the cameras are high, but this is a high and solution that is also legally auditable. You get what you pay for.
I can also view these on my computer - though Java issues mean I can only watch one cam at a time on that software (with a Mac).
