After the detector completes the detection work, it transmits the alarm signal to the security alarm panel, and the security alarm panel begins to perform the task of transmitting the alarm signal to people. When the security alarm panel transmits alarm signals to people, there are 4 channels as follows:

1. Air transmission channel: The alarm sound emitted by the processor of the security alarm panel can be directly heard by people through air transmission. This transmission channel is generally used by car security systems, but it has certain limitations when used in home security systems.

2. Mobile communication transmission channel: This transmission channel generally refers to a channel that uses existing mobile communication networks to transmit alarm information to people through the processor of the security alarm panel. Because using this channel requires the installation of a mobile communication module with a number on the security alarm panel, which incurs monthly rental fees, the production and usage costs of this type of security alarm panel are both issues that affect market promotion.

3. Landline transmission channel: The processor of the security alarm panel transmits alarm information to people through a landline. However, if the criminal first cuts off the landline before committing the crime, then this channel will not work. So, in the security industry, it is generally recommended to use dedicated lines. Of course, in an increasing number of households, landlines are pre installed by construction companies. When it is difficult for criminals to find and cut off, using landlines as a transmission channel is also a relatively safe method, and now the vast majority of home security alarm panels use this transmission channel.

4. Dedicated transmission channel: The security alarm panel transmits alarm information to people through a specially installed line. This transmission method is generally adopted by network security systems. The so-called “network” refers to setting up an alarm center in a place with a security duty room, and the security system installed in each household uniformly transmits alarm signals to the alarm monitoring center at the end. Because this dedicated transmission channel has high anti-interference and reliability, it is adopted by important departments such as banks, military, museums, etc.

On the surface, security alarm panels, anti-theft doors, anti-theft nets, and building anti-theft door intercom systems all belong to security products. But apart from the security alarm panel, no other security product has the function of alarm. The security system will undoubtedly become an essential security product to meet the security needs of thousands of households and various industries.
