Bought the 2k security camera with built-in in solar.
The reason was having to charge our previous camera (different brand, HD) every five days.
It's been installed (south facing) now for three, touching four weeks, most of November during which we've had a few sunny days, we lose the sun around one/two ish.

This has kept the battery from full charge, to around the eighty per cent mark. In this time the camera has recorded hundreds of thirty second clips.
The app provides two very useful graphs showing battery usage and solar charge.

The other features actually work! (Unlike my previous which captured cars ,leaves, everything and anything)
Motion sensor, just detect human activity, Motion zones.

The resolution is a step up, in daylight it's very good (I personally would like 4k or above but I understand about battery life etc)
The image does not distorted when zooming in and is good and clear and although it has a wide view, it doesn't distorted the image (like looking through a fish bowl)

The night image is better than previous but it can produce a grainy image when zooming in.

Over all I'm very impressed with the quality, battery life and features of this inexpensive camera I would definitely recommend it
