Hi, I have an idea of a circuit with a range of frequencey suitable for that hall and whenever the remote control is out side the hall there will be a signal to cutt off the power supply from the remote control. So if u can improve the idea. I don't know it may work or not just an idea!!

Hi Ante many thanks to u, We r not afraid from theft, but we don't want the remote control to operate outside the hall or at least to give an alarm for safety reasons. Thats it ;) Thank u again

Good Day To you All During risk assessment of crane remote control operability range, it was found that the remote it operates the crane even from outside hall. Therefore, it was found it's not safe to operate the crane out of vicinity, remote control supplier was approached for reducing the range which they confirmed it's not possible. we have an idea of modifying the remote with sound alarm whenever the remote is taken out side the hall. Or whenever the remote is out the hall the remote power supply has to be switched off automatically. So please if u have an idea of implementation this idea or how to build such this circuit, or if u have any idea where to find an equipment to do this (reducing freq. range or the above suggestions. please as soon as possible.
