The Securitas Direct Sentinel anti-prohibition alarm is disabled, and the alarm will remain active. Since the ATN network is used, the interference detector can send an alarm to the alarm receiving center when it detects frequency interference that attempts to interfere with the safety system. The Sentinel system also has an SOS button through which you can immediately contact our security experts, and we can help you in an emergency. Because of this uncontrollable system, it has been possible to take action in less than 30 seconds since the problem was discovered, with excellent value for money, as well as invasion, destruction, medical emergencies, or fires.

The progress of electronic warfare is one of the key factors guiding the development of armed autonomous systems. At present, drone aircraft are launching electronic warfare with cellular communications, but it is not difficult to imagine that the same theory applies to new technologies. In this case, it is easy to imagine that other vehicles will become jamming devices in the future battlefield or even in the current battlefield. Identity verification attacks or more generally "interference" attacks may violate the laws or regulations of certain countries. However, it is often difficult to determine the source of interference because it is small and easy to hide.

As we said, we are very dependent on wireless networks. Wireless communication is like two people talking. One of them speaks and listens, and vice versa. What happens if the third person approaches them and starts shouting so loudly that the other two can no longer listen to each other? First, they will try to continue the conversation, but soon they will realize that this is impossible, and they will stop talking while waiting for the lunatic to remain silent. This is what happens with many communication protocols. When they found that the chain was already occupied, they withdrew. Therefore, the exchange of messages between these devices is suspended. Even if they try to communicate without support for free, just like other protocols, if the noise is too loud, the other side will not be able to receive the message correctly and will not be able to communicate. This is what we call wireless interference.
