These are excellent cameras and the wifi works well. The rechargeable batteries usually last about 6-7 months. The drawback is they are attached by a strong magnet. This is usually fine. I had one stolen recently and Netgear doesn’t register the cameras even though each one has a unique identifying code. So presumably now being used by someone else. I got a screw headed bolt that fits the camera and into a hole in a piece of steel (Actually a cut down IKEA wall bracket which has 2 just well spaced holes) then a window lock attached to the wall and the metal stud goes through the second hole. If it’s stoled now it will be very hard to take and only if it is broken. Come on Netgear you can do better than that.
