Just bought the Reolink RLC-511W. https://reolink.com/product/rlc-511w/

Hope it is good.

yeah. quit cheap and with free shipping. from official store so no need to worry about authencity. haha.

quite good.

Good
1) 5MP picture quality is good.
2) 4X Optical Zoom is useful.
3) User interface for the app is quite good. It is also very easy to setup the camera for first time.
4) Price wise it is totally more worth it to get this than any cheaper brand like TPlink etc.
5) Viewing angle is reasonable at maximum 90 degree.
6) Email alert for motion detection is quite good.

Bad.
1) When viewing the camera in 5MP mode, somehow it keeps on complaing the network connection is poor therefore the live streaming will have jittering problem. but using balanced mode no issue. My home unifi is 100Mbps, however, it should be more than enough to stream 5MP camera without issues. Dun know why though. To be fair balanced mode to me is also quite good enough in terms of image quality, so i am ok with that. Maybe next time upgrading my home broadband to a faster speed to see if it improves.

this is my first time using this brand of camera, it is totally good user experience to me. will certainly buy it again.
