    In fact I would like to say: it could be necessary to install the device in a closed area, at least closed by means of '(this kind of barrier)', in order to avoid people cutting voluntarily or by accident the sensor beam

    Any idea to say that or rephrase it?

    Maybe just by using 'fermée par des chaînes', so should I use the word chain?

    The device should be set up in a restricted area, cordoned off/ protected by a chain to prevent people from accidentally or deliberately getting in the way of/cutting/interrupting the sensor beam
