HD100 Video Cameras Not Working

Noticed my cameras were no longer working. They were previously. Any suggestions on troubleshooting?

Do you have power to both cameras? Have you changed your wifi security key or are you using a new router?

If everything else is the same, unplug the cameras for a minute and plug them back in to power cycle. Do the feeds return?

Sometimes you may need to power cycle your router, then power cycle your camera
