Nest camera, has a different definition for Turn off Mode

Findings of a research show that the Nest camera is still operating even after it has been disabled through the mobile application.


People buy security cameras to have a higher level of control over their lives, but recently a research by a team at ABI Research found that users also must be worried about the security device itself.

nest camera 1024x696This news is about a security camera of Nest Company that was acquired by Google in 2014. The device is the latest product of Nest that enables users to see live video of their homes or to be notified about unusual motion or sound. Findings of research show that the camera is still operating even after it has been disabled through the mobile application. The LED indicator approves that the device is off, but the current drain illustrates something else. It is expected that current drain drops significantly when a device is disabled, but it's not true in the case of Nest camera and current drain decline just 30 mA when the device in turn off mode.

"When a device goes to power down mode, you expect the current drain to drop quite a bit," said Jim Mielke, a senior analyst at ABI Research.

The following table published by ABI research and depict current drain for different modes of operation.

               Mode                            Resolution      Current
Video Record – no motion                1080p           371mA
Video Record – no motion                720p             330mA
Video Record – no motion detected   720p            418mA
Video Record – no motion                360p             322mA
OFF Mode                                                           343mA

"When Nest Cam is turned off from the user interface (UI), it does not fully power down, as we expect the camera to be turned on again at any point in time," said Nest Labs in a statement. "With that said, when Nest Cam is turned off, it completely stops transmitting video to the cloud, meaning it no longer observes its surroundings."

It can be argued that turn off mode has a unique definition universally and Nest approach to define turn off mode is bizarre. Even though Nest used 128-bit secure sockets layer (SSL) encryption, perfect forward secrecy and a 2,048-bit RSA key unique to each camera, but users might face new security risks. Lastly, this camera uses electricity constantly which is not an efficient practice in 21th century.
