Hello
I need to replace an old ip camera. Can anyone suggest me a cheap camera that can be bought on Amazon?

Thanks
Fabio

Theres probably a billion choices since so many of them are just rebrands of either Dahua or Hikvision. It also depends on what kind of camera you want and what "cheap" is. If the $50 ballpark is right for you I have been VERY happy with my SV3C brand cameras I purchased all from Amazon - links for my specific models in my signature but they have others. Depending on what you want they have some 2-packs for $80.

One minor note, of the models I've bought, they have two trains... the A-Series and HX-Series. I much prefer the A-Series (mostly based on differences in the WebUI).
