To enable the feature where the speaker shows the camera video on its screen when a user says "show me camera", two services need to be purchased:
1. Product PID voice control activation: This grants the speaker the ability to parse and respond to user commands. This service is compatible with multiple platforms including Alexa, Google Home, and Yandex Alice.
2. Device UUID video streaming activation: This enables the cloud server to successfully access the device's live video feed.
If the product has already been enabled with Alexa or Google Assistant, it is necessary to check whether the "IPC Video Streaming Push Service" has been activated for the device.
Note: If the service is already activated on the device, it cannot be purchased again.
