Amcrest Link app show black

[hhcan]

I have the Amcrest 960H that worked fine until I unplugged for a day. Today I plugged back in all channel cables in the back and turn on the DVR power. I only got video shown on my monitor but the Amcrest Link on both my iPhone and Galaxy s6 don't show any video; instead a black background is shown on each channel. The app connects successfully to the DVR though. My bitrate is 24 kbps vs 400 kbps a few days ago when everything was still working.

What could be the potential problem?

Thanks in advance.

Hello,

Not sure what could be causing this. Try deleting the device from the app and then add it again.

It turned out my friend unplugged the power to the camera when he painted the wall. Plugging in the power cable put everything back to normal. Thanks.
