Finally found a decent & cheap IP camera: Dericam

Would you guys still recommend this camera or is there something better?

Well the software issues appear to be resolved. I sent back one of the two, but the remaining one is going strong. For the money they are hard to beat IMO

I currently have both P1 and P2 but playing with P2 as it has better resolution.
It works via Dericam Android app, Onvifer and web interface.
However, its motion detection feature is pretty useless as I had to set sensitivity to 15 because it kept generating alerts during night time.
I also was unable to set up email settings, it just keep saying Failed without any reason so debugging is pretty tough :\

Do I get it right that it is possible to use abovementioned ffmpeg motion binary sensor instead of the camera’s one? How does that impact the system’s performance (I use it at RPi3)?

Hi. Did you manage to sort out the sensitivity on the Dericam? I’ve just installed one and even with the setting at 1 it seems to be set off by a cat sneezing(!)

The email problem is probably because it is a “less secure app” as far as your email provider is concerned. I have GMAIL and had the same issue. You can allow less secure apps to access your Google account (not recommended) or set up 2 factor authorisation and then set up an “app password” for the Dericam. It took a while to work that out.
