The function of the external radiation unit is to achieve the emission of infrared signals, and it is the only intermediate device for communication between the system control computer and the receiving unit.

2. The intensity of the infrared radiation unit's emission signal can be adjusted with two types of power: 15W and 25W, and the effective emission range can reach 20/30 meters.

The connection of multiple radiation panels is carried out hand in hand, and directional brackets (adjustable angle) can be used for easy construction
