I'm not a negative person, but this device is trash !!!! The only posiyive is light sensitivity, sharpness and detail. But you can not use it for Alarm Recording. The problem is that you can ony set the Alarm recording time to max 60sec. Between these 60sec there is ALWAYS a Alarm Interval of min 30sec. So always 30sec loss of evidence. There is NO WAY to make alarm-recordings from 2,3,5 or 30min. It's unusable.... Also no option to download the recorded video from the SD-Card to your phone. You can only play the recorded SD-Card video file on your phone - while the player is playing the video, you have to hit the reccord button in the APP to make a new recording on you phone. This means if you want to download 5 hour of video to you phone, you also have to play it for 5 hours.... BAD BAD BAD.... This is were i stop testing it... The only thing you can do is reccord video continuously (Alarm=off - Auto=On). This way you can choose between 1,2,3,5 or 30min file size recordings.
It does not matter how many seconds you set the Alarm-Interval. There is still no way to make video's longer than 2-3 min. It has a mind on its own. I will not use it. (So many device's on Aliexpress are bad, i already spend 250-300$ to buy different kinds of them. They almost SUCK all of them)
Battery doesn't work. It can only work connected to a power source.
