1. If the network speed is slow
•
We recommend internet upload and download speeds of at least 30mbps each, as speeds below this may result in a less smooth display of the camera vedio.
•
Slow internet speeds may lead to screen freezes or disconnections.
•
To check your internet speed:
◦
◦
Click the 'Start Test' button to the test.
◦
After the test is complete, verify the download and upload speeds in Mbps.
•
If your speed is slower than the recommended speed, consider rebooting your router or contacting your internet service provider for assistance.
2. When the camera cannot be loaded on the web
•
Gooroomee is a program based on WebRTC, and if your device is below the recommended specifications or does not support WebRTC, it may not be able to load the camera for video.

How to check if WebRTC is supported:
◦
Allow both camera and microphone.
◦
Check if both the camera and microphone are recognized, and if video is visible on the screen.
