What are bidirectional alarms and how do they work?

Nowadays, there are in the market a multitude of different alarm systems and cameras. The available supply has grown rapidly in recent years and has resulted in the launch of new innovations in this sector.

Among so many offerings, it can be difficult, sometimes, to distinguish the different types or the specific characteristics of each one.

In this post, we will go deeper into the so-called bi-directional or double-track alarms. This type of alarms, which we use here in CIS Serra, are very useful to combat the use of inhibitors, and at the same time allow to communicate with the alarm from the Central Receiver of Alarms.

What are bidirectional or double-track alarms?

Alarms can be divided into two main groups according to the signals they send and receive. These two groups are unidirectional alarms and bidirectional alarms.

Unidirectional alarms only send signals in one direction (even if it is through one or more channels) from the alarm to the Central station, so the Central cannot intervene to stop the alarm, make revisions, etc.

On the other hand, bidirectional alarms, the only ones that we use in CIS Serra, can send signals to the Central, but at the same time the Central can send them to the alarm. This allows the Central to activate or deactivate an alarm, check its status and obtain data constantly, among others.

In our case, in addition, the communication between the central and the alarm is constant 24 hours a day, 365 days a year, so we constantly know the status of an alarm remotely, without having to make face-to-face checks.

Double protection against intruders with double channel installation.

After explaining bidirectional alarms, it is important to highlight another issue that can sometimes lead to confusion. On the one hand, as mentioned above, we can differentiate the alarms according to the directions of the signals, depending on whether they send signals in one direction or if they can also receive them.

On the other hand, we have the so-called "transmission channels". The channels of transmission of an alarm are those routes through which the alarm sends the signals to the central station. The number of channels of an alarm will depend on the preferences of each one but in CIS Serra we recommend using two or more channels.

The Achilles heel of many generic alarms is precisely the communication with the AMS. When only one channel is available, the criminals can disable it, thus preventing the signal from reaching the central, and therefore, the police. That is why in CIS Serra we carry out most of the installations with two or more channels so that disabling is much more difficult or, even, impossible.

The multi-channel installation, together with our bidirectional alarms, allows you to obtain maximum system efficiency and protection for your home or business.
