Thank you very much for your valuable advise.
The solution issue is not only subjected to budget alone, but the arial distance is more.
This situation is just like, consider the case of a big club, spread across 3-4 miles in diameter, which includes a health club, restaurants, coffee shops, snooker club, and many others spread across the entire area. And the surveillance is to be done in the entire area and the cabling seems to be bit difficult in that area...
So In such a case, what sort of solution do u suggest.
thanks and regards
