Review on YI Indoor Wireless WiFi Security IP Camera Dome Guard: Smart Nanny Pet Dog Cat Cam 2-Pack with Night Vision, 2-Way Audio, Motion Detection, 360-degree Coverage, Phone App, Compatible with Alexa and Google by John Faxon

So, in the comparison photo, this camera is the camera in the lower left window, marked as a motorcycle. I bought a $40 Yi camera a few years ago and it did what it was supposed to do. Wanted a second camera as I was traveling and needed to cover the second car. Went with yi so I didn't have to download a second app. During the day, the cheap model is just as good, if not better than the $40 model thanks to more features (playback speed options, sound alert options). However, $40 a night is significantly better than this model. Both are on the same settings at the same time, but the cheap one is almost invisible. Night mode is useless behind glass as infrared radiation is reflected directly into the camera. Since it was not mentioned in the description, the camera can use up to 128GB SD card. As long as both cameras have an SD card, the cloud isn't necessary either, although yi is pushing this hard. Update: 09/13/21 - Go to the game market and read all the negative reviews before buying. Yi recently updated its UI to fully push its cloud system. Not as comfortable as before when using an SD card. I wouldn't recommend it again until they fix it.
