Jun 07, 2018

The video doorbell adopts 2.4G video transmission technology. This frequency band is an internationally-required free-to-use frequency band, and it is not necessary to pay any fees to international organizations. This provides the necessary favorable conditions for the development of 2.4G wireless technology. And 2.4G wireless technology is different from the previous 27MHz wireless technology. Its working mode is full-duplex mode transmission, and it has absolute advantage in anti-jamming performance than 27MHz. This advantage determines its superior anti-interference and transmission distance up to 10 meters. In addition, 2.4G wireless technology also has a theoretical data transmission rate of 2M, which is double the theoretical 1M transmission rate of Bluetooth. This technology was added to make the video doorbell more stable.
