Video Quality: Daytime pictures are about as sharp and clear as we've seen, which means you can see most but not all of the details and subtle patterns in the scene. At nighttime, the video is very good: quite viewable, with a fair amount of brightness and clarity.
Data security: This model has very good security. It has many of the important protections for your recordings and personal data.
Data privacy: Google Nest offers only a mediocre level of control and transparency over your data. They are not doing as good a job as others are with regard to collecting only necessary data, giving you control over its use, and limiting how your data is shared or sold.
Response time: This model sends its alerts to its app within 6.5 seconds on average, which is moderately fast, though not as fast as others, which means your ability to respond may be a bit delayed.
Smart features: It works with smart-home systems such as, Google Assistant, and Google Home.
