The challenges i have that lowered the rating arebattery only lasts for about 3 days if you use motion detectionmotion detection picks up a lot of false negatives creating a lot of extra video to watch when looking for an eventno user interface everything is done through modifying config files not a big deal but i like easy to use guisthe camera randomly will lightup a visible blue light not sure why i use a piece of tape to hide itdoesnt work well in low light which it didnt claim to do so not really a knock on the camera as much as my disappointment i have to leave lights on at all timesthe instructions were somewhat confusing and didnt match the camera
