Sorry to hear about this experience, neighbors. In most cases, any delay in video or notification are going to be related to signal strength and mobile phone connection. Check out our Community post about RSSI for tips on optimizing signal strength.
Once RSSI is optimal for quick connection, we recommend also ensuring the mobile device and app connection is sufficient. Please disable features such as bluetooth and VPN on your mobile device. I recommend also testing video/ notification efficiency with your phone connected to wifi only, and cell data only, to see which connection might be better.
Another great tool for quick connection is the Rapid Ring App, which is designed for the quickest access to live view. If these concerns persist after trying the above steps, the best next step would be to reach out to our support team for more in-depth troubleshooting.
