Surveillance Cuts Both Ways
The story here is not about Nest, a Google product that captured images of a masked intruder trying to gain access to a home. The story is about how Nest (Google) told a customer their video was deleted when, in reality, they meant the footage was just not accessible by the client because she hadn’t paid. Google had the footage in a file and could access it
How and Why a “Deleted” Nest Video Was Found
When Nancy Guthrie, mother of TV journalist Savannah Guthrie, was kidnapped, cops said the Nest doorbell at her house had sensed motion that night, but because she didn’t have a paid subscription, the video was gone. Without a subscription, Nest only keeps short clips for about three hours, then deletes them.
Ten days later the FBI, working with Google engineers, announced they had recovered video from the camera. They said the footage came from “residual data” stored in Google’s back‑end systems. No explanation has ever been given for a description of “residual data.”
How Nest Cameras Work
Nest cameras don’t store everything locally like old DVRs. They constantly send video to Google’s cloud. Even users without a subscription rely on Google’s servers to detect motion, send alerts, and give short‑term clip access. To do this, the video must be recorded, uploaded, cached, and kept for a little while on Google’s infrastructure. “Cloud” is an euphemism for “someone else’s disk drive.”
Because of that, the footage existed in Google’s system before the owner decided whether to pay for long‑term storage. When the user’s account could no longer see the clip, copies or cached pieces still remained on Google’s servers. With the FBI’s help, those hidden pieces were pieced together and recovered. Again, no explanation or description was given for the FBI “help.”
What This Means for Users
For paying customers, Nest promises to keep video for 30 or 60 days. For free users, the promise is that the video disappears after a few hours. The reality shown by this case is that “disappears” really means “you can’t see it anymore.” The data may still be stored somewhere in Google’s backend, at least temporarily. Think of a “backend” as a human digestive tract. IOW, where “stuff” is eventually expelled.
This raises a trust issue. Customers usually think that if a video is deleted, it’s gone forever. But the Nest example shows that the company can still retrieve it when needed, such as for a criminal investigation. Or when it suits them such as compiling a list for a Police State. While it’s good that investigators got useful evidence, it also shows that the company’s marketing doesn’t fully match what happens behind the scenes.
Other smart‑home cameras face similar criticism. Ring, for example, was recently criticized for a feature that lets neighbors share footage to find lost pets or suspects, sparking worries about a large, private surveillance network. The author uses local storage cameras that don’t “phone home.”
Bottom Line
The Nest incident proves two things:
- Technical reality: Even without a subscription, video is captured and kept for a time by Google. It can be recovered if authorities have a reason. Or, even without a reason or judicial warrant as is often the case in authoritarian Police States.
- Perception problem: Users expect “deleted” to mean “gone forever.” When the truth is different, trust in the brand can suffer. In today’s fraught environment, trust is not just gone, it has been shattered. This applies to ALL corporations, even smaller businesses that subcontract their security to companies using larger companies’ services. Your small business “Mom & Pop Biz” might have a small local alarm company install cameras and security sensors at your small “stick & brick” location. What you don’t know is that the small, local security company uses Google Cloud to store all their data because it’s cheaper and more convenient. Once again, you can be screwed when the MAGA crime syndicate wants your data.
Companies need to be clearer about what data they keep, how long it stays, and under what conditions it might be accessed again. Transparency helps users make informed choices about the trade‑offs of always‑on cameras. If they don’t tell you, ask.
Regain your privacy
First, replace all interior cameras with local storage devices that keep your footage locally on a disk drive or USB thumb drive or SD cards. Locally means in your device, under your control and unavailable to anyone else unless they have direct, “hands-on” access to the device. Next, replace the cameras that cover your most used areas. For example, your front door and garage door are probably the most active areas so replace those cameras with local devices. Local doesn’t mean “off grid,” it simply means not connected to the internet. Local cameras can be connected to your home network and store files on a central disk drive, your own “cloud” so to speak. If you’re really security conscious, stand-alone trail cameras normally used local storage and access is easy if cops need to view the footage. Eventually, get rid of all cameras and sensors that “phone home.”
