Tamper-proof / anti-removal sirens

Tamper-evident / tear-off protection

— additional protection against attempts to disable the device or interfere with its operation: if such attempts are detected, an alarm is generated. Note that the specific features of such protection may vary, depending on the type and specific model of the siren. Some devices react to violation of the integrity of the case, others - to loss of contact with the supporting surface, others - to characteristic shocks, shocks or vibrations that occur when trying to open or tear off the model, etc. Such nuances should be clarified separately. However, in any case, this type of protection provides additional security; it does not provide an absolute guarantee against interference in the system, but it greatly complicates such a task.
