no problem. just trying to put as much info as possible on reasons when and how often to check a camera. i think there are a lot of variables that must be weighed in on the decision. I am sorry if I sounded defensive or anything other than just trying to be helpful. I am still puzzled as to why people buy them when you can build 10 x the unit you can buy for almost the same amount of money IMO. oh, well good luck on what ever decision you make on checking your cam. I think you will know what will be right for yourself after a few trips checking it. p.s for those of you who might be interested in building a cam, the smallest unit now that can be made will fit in your pocket. yes, you got it in your shirt pocket. the units are ever getting smaller and better that the people are hacking. good luck my friend.
