I have a piece of equipment that is remote to my location, ie. a DVR recording CCTV images at my mother's house which I can access over the internet. It sometimes stops responding over the internet but is working fine locally. I wish to know if anyone is aware of any way of 'polling' the DVR automatically. I have sussed out what to do at the local end. I will basically have a piece of equipment that will receive these 'polls' and if it does not receive them then it will automatically reboot the DVR. It is the receiving the polls bit that I am struggling with. Any ideas? TIA.
