I have been there. Tip: Now that you have the camera down, write down the Setup code on the bottom of the camera. If you ever need to set it up again, you should be able to just get close enough to the camera that your Bluetooth can connect during the setup and enter the setup code when prompted.
I have had the exact same issue as your pictures show.
Initially my problem was that Night Vision was too dark and missing people coming into the street trying house and car doors so was useless for identifying the individuals. My solution was to leave my Philips Hue outdoor light on all night at the front and turn off Night Vision, that helped capture unsavoury types that were coming into the street.
It has since progressed to being blurry and washed out during the daytime which in turn has multiplied at night whether Night Vision is on or off so I either get a ton of false motion detected events but people go completely undetected walking past the camera unless they are right in front of it (less than 1m away).
My cameras are showing that they have nq-user 1.69 OPENMASTER 376297 firmware, so looks like the problem many have had here has continued from 1.67 into 1.69. I am now getting to a point where I am considering retiring all of the Google Nest Cameras and Doorbell I have to switch to another system as at the moment the Cameras are completely worthless as soon as the sun sets.
17th August 2023 - Person attempting to break into cars, you can see the grass and bush at the bottom of the picture have definition
30th September 2023 - There is a blurry haze over the whole image, grass and bush at the bottom of the picture have no definition, people walking between the cars when the image is like this are not detected or recorded as events.
Google thinks their 1.67 software is an enhancement to Nest Cam Battery, they think they did us a favor, I am so mad right now, reading their announcement about the software made me lose all hope that this was just a big but now it's clear it's a feature. Look at this night vision comparison and tell me who in their right mind would think this is an enhancement
and the third image is from my other camera showing my partner with his white shirt glowing blue, like it's a reflective vest, his skin is glowing it looks like he's on fire, how thinks this is an enhancement? I'm tired of buying products from Google only to either be ruined or abandoned, this deserves a lawsuit.
