What is the Wake-up Sensitivity of my battery camera/doorbell?

How does the battery camera/doorbell be woken up?

To conserve power, the camera is typically in a sleep state with low power consumption. It can be woken up by performing operations on the app, such as viewing the live stream, or by object moves detected by the PIR sensor.

PIR sensor means passive infrared sensor. The term 'passive' refers to the fact that PIR devices do not radiate energy themselves. They work by detecting infrared radiation emitted by or reflected from objects.

The camera is equipped with twin sensors that detect changes in infrared radiation when an object, such as a person or animal, moves within its detection area, and this change triggers the camera to wake up. It is worth noting that frequent heat source movements may cause the camera to frequently wake-ups, and the camera wake-up time will be affected by its usage scenario, for example, the camera will be easily woken up if it monitors a crowded street.

Additionally, due to the sensor mechanism, they may not detect objects moving directly toward the camera to some extent.

Please note that configuring Activity Zones or Privacy Zones will not impact the PIR sensor and cannot reduce the wake-up times.

What is Wake-up Sensitivity?

Generally, Wake-up Sensitivity refers to the camera's sensitivity to PIR sensor triggering. Higher sensitivity results in longer detection distance, easier wake-up, and more recordings, which will reduce battery life.
You can adjust the sensitivity based on your needs and specific scenarios.

Here we take the Tapo C420 as an example, and you can go to the Tapo app> the camera's Device Settings > Detection > Wake-up Sensitivity page to adjust the sensitivity value.
