What does home alarm 868HMz bidirectional transmission mean? Let's answer this question separately.

868HMz: refers to frequency. The frequency of household alarms is 433, while the frequency of 868 is widely used in foreign countries.

Two-way transmission: transmission mode. That is, there are at least two lines on both sides of the communication. The transmission of Party A corresponds to the reception of Party B and the reception of Party A corresponds to the transmission of Party B. This is bidirectional transmission.

For unidirectional transmission, that is, there is only one communication line, and one party sends and the other party can only receive, and it needs to compete for the transmission right.
