Bests & Worsts Reviews from Amazon

I bought multiple cameras from different brand names, also bought multiple model from Amcrest, this is certainly a good quality camera, especially it's very clear at day time. The only problem is the amcrest 4K model IR night is not light up as the amcrest 4M model which is almost 40 dollars cheaper than the 4K model. So if you want a better quality picture at night time, your best option is to use this 4k camera with a IR light. an IR light might cost you extra $20. The alternative solution is to buy ther 4M model, which is less expensive, and have much brighter screen at night. 4M model can see a circle of red IR light around the lens, for the 4K model, you only see two of the IR light below the lens. When comparing to other brand name on amazon: Lorex camera has similar shape like Amcrest does, but it only works with Lorex NVR. GeoVision camera cost more with the similar configuration from Amcrest, but their mounting bracket cost a fortune, a round shape branket cost me $54, which is ridiculously expensive. Update: one of the camera stop working at about 4:00 AM, after reset, it works again.
