This may sound a bit crazy but another recommendation is dogs. The reason I say this is that the first reach on our trip in Feb. we stayed at catcha gardens for the first week. They had these 2 wonderful dogs that not only were very friendly but excellent gaurd dogs. They would make thier rounds every day and all thru the night. They let you know imiadiatly when someone was on the property that did not belong there. I was quite impresed with them. I loved looking out the window and seeing 1 or both sleeping on our terrace. Un like a human gaurd, dogs seem to have 6th sense about their surroundings. These dog intruduced themself right away to any new ppl staying there so they knew who belonged and didn't. when they had to they sounded vicious . We loved them and we did not even feed them. They seemed to sense what their job was there.
