First thing is to be notified when your camera goes offline. Consider configuring camera offline notifications on "manage camera" page of each camera. You can add up to two email addresses. You will be notified once the camera is offline for 10 or more minutes. We offer this for free.
To find out what was the reason which is causing the camera to be shown offline, try following this checklist:
- Reboot the camera. The easiest thing for you to be sure that it isn't stuck. In most cases, we are using a separate streaming protocol to connect to your camera, so even when you can otherwise access the camera, only the stream itself can be stuck
- Make sure that the camera is actually working. Try connecting to its local web admin interface, for example, check its status LEDs or mobile app connection.
Verify that your public IP address is correct. With many internet connections, you'll only have a dynamic public IP address, it means that it can change from time to time (usually with every router reboot), effectively disabling all remote connections. Make sure that the IP address saved on the "manage camera" page of your camera corresponds with your current public IP address. If it doesn't, please update it.
To solve this issue completely, consider either asking your ISP for a static IP address or use some DDNS service or use our AngelBox to overcome this once and for all.
- Check your network configuration in general. Be sure that the camera has an access to your router and especially that your current router port forwarding rule is correct. You can again use this guide to make sure you didn't miss anything.
