I have had Blink cameras for about 10 years now. Nothing has ever been fixed as far as short clips no matter the settings. What I am going to do eventually is leave Blink and buy a different security system that works as advertised. I don’t think Blink can fix this issue. As I said, 10 years now. Have tried new cameras, new batteries, rebooting, etc, etc, etc. Nothing work. Suggest a different security system if you can’t live with short 4-5 second clips.
