The following should be undertaken when troubleshooting why one or more cameras are offline on your device.
Step 1: Check the camera status
Is the web app displaying a blue screen (No Video Available)?
Is the Diagnostic Log (Configure tab) indicating a camera issue?
– If so:
Try deleting and re-adding the camera
Step 2: Check for camera power issues
Check if power is being supplied to the camera
If your camera supports Power over Ethernet (PoE):
Have you connected an Eehernet port between the camera and a PoE port on your device?
If your camera does not support Power over Ethernet (PoE):
Is your camera's power adapter connected and powered on?
Is there any LED activity on the camera?
A lack of LED activity could indicate a fault with your camera - please contact your camera manufacturer if you are unsure.
Does the camera execute its Power On Self Test (POST)?
What is a Power On Self Test (POST)?
What is a Power On Self Test (POST)?
The POST (Power On Self Test) is where the camera, when first powered on, performs a diagnostic check to ensure that it is functioning correctly - during a POST you should see the camera panning/tilting/zooming by itself for a few seconds until the POST is complete.
If more than one camera is offline on your device you should also check that there are no issues on your local network that could be preventing your device from communicating with any of your cameras.
