You're right, according to our information this is a battery-operated network camera.

The experienced battery life of the hue camera depends on many factors, e.g. the temperature, the age of the product, the average clip length and the number of events per day. Cold temperatures, long clips and the total number of events per day have a negative effect on the battery life. With typical use at 20 degrees Celsius and 10 wake-ups per day, resulting in 10 clips with an average duration of 10 seconds, the expected battery life is 3 months. To improve battery life, we recommend arming the camera only when you want to generate events and ensuring that the camera's field of view does not cover busy areas that cause frequent wake-ups. The camera wakes up via a passive infrared sensor so that the camera can also wake up in activity or blackout zones, even if it is not recording clips. You can also improve battery life by reducing the motion sensitivity and reducing the maximum clip length.
