The most important advantage of this type of alarm is its lower price level compared to other types. But they also have less capabilities.
Perhaps it is because of the lower price of simple alarms that more and more people prefer to use these models. But on the other hand, you should keep in mind that when choosing an alarm, the appearance of the remotes of this model will definitely not satisfy you. Also, the capabilities that mainly video alarms have are not seen in this type of alarms. For example, if your car is hit and starts to sound the siren, you will never know what the siren sounds like. The car may have been opened or hit.
Also, if your distance from your car is outside the range of the alarm antenna, you will not notice the annoying sound and you will not receive any message via the remote. In addition, the antenna range of this type of alarm is much less than video and SIM card models. So that the best model of simple alarms may eventually have a range of up to 800 meters. In a way, it can be said that the only advantage of these alarms compared to the central lock that is present in most cars, is that if the doors are knocked or opened, the siren will sound and you will notice the danger when you hear the sound.
The most well-known simple alarms in Iran are Hoti alarms and simple models of Steel Mate.
