Blink Doorbell (Blink App View)

My camera 📷 is blurry dose the weather effect it if its Cold ❄ out or i need to fix something

How do u go live?

I just have the Blink doorbell. My screens don't show the two bottom corner icons for video and camera! I can't get any live view only videos when the door bell is pushed or motion is detected. Any idea??
