Small factor, lens flare is not bad, the ptz speed is pretty good, the zoom in/out ihas a decent speed, installation was easy and the cam registration is pretty straightforward, i use the dahua app as my main viewing platform and the time to load is pretty fast wifi/cellular, however it has limitations once zoomed in you cant tilt up, the IR is pretty bright just make sure not to install it next to an object otherwise you lose your view due to the illumination, the cam IVS function (human detection is pretty sensitive and i like that) overall happy with it and i recommend this product.
