Tunnelling protection for fence systems

On unpaved ground, there is always the risk of intruders tunnelling unnoticed beneath fences and thus gaining unauthorised entry. To protect against this, HAVERKAMP offers additional crawl and tunnelling protection features that can be added to individual fences. Any tunnelling attempt is detected and an alarm signal transmitted. The tunnelling protection function is indiscernible from the outside and can be retrofitted to any fence system.
