The loading up or viewing of your Indoor + Outdoor camera's livestream is greatly affected by its resolution. The lower the resolution, the lower is the needed WiFi speed.
Should you wish to change the resolution of your livestream with compromising its quality:
Step 1. Load up the livestream of your Video Doorbell Camera.
Step 2. Tap on the livestream screen.
Step 3. On the upper-right hand corner of the livestream screen, you'll see "Quality : High" you can tap on it and change it to either Medium or Low depending on your preference.
