Doorbell Camera video blurry
I have had my doorbell camera installed for a month or 2. I don't recall it being blurry when originally installed, but now I have noticed the video has become blurry. The plastic protective film is not on and the lens is clean. Is the camera defective or is there someway to focus it? It has a upload speed of 8.66 mbps (Good) and a signal strength of -66 dBm (Fair). The recommended signal strength is -55 dBm. The video is blurry with the picture quality set at 1080p, 720p, and even 480p. Would one expect a blurry picture even at 480p with -66 dBm signal strength?
