Dont buy

Cheap Chinese garbage.
Software upgrades to the cameras usually screw up the camera. Ecosystem not well supported. Software very buggy. Had to fix cameras several times. If you want a hobby camera, this is Ok. If you want a reliable security system, invest in a better more reliable product. Wish I could return my 4 cameras.
