What is a BLU?


Business logic units (BLUs) implement cohesive service logic on FusionInsight Farmer. They are the entity objects of service processing that contain the logic of all services. BLUs can be deployed on multiple instances.

What is AS
Auto Scaling (AS) is a service that automatically adjusts resources based on your service requirements and configured AS policies. You can specify AS configurations and policies based on service requirements. These configurations and policies free you from repeatedly adjusting resources to keep up with service changes and demand peaks, which helps you reduce the required resources and workforce.

What can I do if the video delivered by the local camera is blurred
The possible causes and solutions for video blurriness. Cause 1: The camera had focus problems. Solution: From the remote controlled UI or web interface, repeatedly adjust the camera's focal length and check whether the video clarity changes. If it does, the problem is caused by an inappropriate focal length setting. Adjust the focal length. Cause 2: The camera was old or faulty. Solution: If the video clarity does not change when you repeatedly adjust the camera's focal length, power off and on the endpoint. If the problem persists, replace the camera.

What is Beamforming
The beamforming or Transmit Beam Forming (TxBF) technology produces the strong directional radiation pattern based on the strong correlation of the spatial channel and wave interference principle, making the main lobe of the radiation pattern adaptive to point to the wave direction. This technology improves the SNR, system capacity, and coverage range. Beamforming or TxBF is an optional feature in the 802.11n standard. Beamforming includes explicit beamforming and implicit beamforming. Explicit beamforming requires the receive end to send information about the received signal to an AP. The AP then adjusts the transmit power to the optimal value according to the signal information. This function increases the SNR of the receive end and improves the receiving capability. Implicit beamforming allows an AP to automatically adjust the transmit power to increase the SNR of the receive end based on channel parameters without requiring the receive end to work with the AP. Currently, mainstream terminals do not support beamforming.
