It is a pretty good camera. I have bought 5 for indoor use with a 64GB micro SD card and I have hung them all on the ceiling. The black power cable is a bit ugly, so I had to drill the wall to hide it (it is value for money with 15-20€). It has many features (microphone, speaker, alarm - although not very loud, it detects and follows people, micro SD, WiFi, night vision, it can be connected to Tenda's cloud with a subscription, but it cannot be connected to any other personal cloud of yours, and of course it can be connected with the TDSEE app that sends notifications if you want).
The connection is very easy, you just need to scan the barcodes on the box, under the camera, and finally the barcode for the WiFi from your phone to the camera. I don't consider it a negative that it doesn't have Ethernet (since I didn't want to run an Ethernet cable and it has good range with WiFi), although it could have Ethernet next to the power port (it has space).
I don't know if they will last, but overall I am very satisfied with the price and quality of Tenda, as well as other products I have purchased over time.
