Take some time to study the app, at last able to use, not yet try the recording, pictures is clear,👍 highly recommended, bought at the promotion price, wanted to buy one more, but price no more promotion, too bad.

Fast delivery. Basic function ok. Color rendition is so so under bright sunlight. Can't view on PC. Device quite hot when use. Not sure about out door performance yet. Good for limited function requirements. App update is just OK with one camera, no sure of performance when more cameras are added.

Got it quite fast. hopefully working well
