I've been following this forum for a few months now, and, not being from PA, have really noticed what seems like an unusually high percentage of burglaries and vandalism of hunting camps amongst the members. My family has cottages in the Poconos, but doesn't keep anything of value in them because a rash of break-ins in the '70s cleaned out most of the antique furniture original to many of the local cottages. Thankfully, we haven't had to take any special precautions beyond not leaving valuables between Summers in my lifetime, but I know that isn't feasible for many of the hunters and their shared camps. I think I might be able to assist anyone looking for technical solutions to security problems at their camps. I have quite a bit of experience doing this same type of thing in a number of developing nations where conditions are primitive, but threats are real. The IP-based cameras already mentioned are a great option, as they are the most thorough with near-real time video, but there are some shortcomings in that you have to be monitoring it to know when someone is present and when to notify law enforcement, have to have high-bandwidth internet at the location, and leave expensive equipment at the site (routers, cameras, computers, etc.). An alternative, that may work for more of the primitive camps is a GSM-based intrusion detection system (IDS) that will use a passive infrared (PIR) sensor, like in a home security system, which when tripped would send a text (SMS) message to a list of designated cell-phones from the pre-paid (or contract) SIM card in the IDS. If notification of a breach into your camp is insufficient, it can be built to send a media message (MMS) with a still photo of what it sees when it is set off. These types of systems can be run with A/C power directly, or a battery pack and relay can be built that has very little draw, but will wake the IDS when the PIR is triggered, then put it back to sleep after sending the SMS/MMS. There are commercial off the shelf (COTS) systems like I described available ( http://www.gsmalarmsystem.com/gsmala...larm%20Systems
), or better ones can be custom built for less cost and more, tailored capability. The real key is the pre-paid SIM card that doesn't have minutes that expire over time, and whether to use this device openly as a deterrent or concealed to ensure survival and continuous evidence gathering prior to police intervention. PIRs, IR trip wires, magnetic contacts on doors/windows, change detection software, etc., can all be used to trigger the SMS/MMS either as indoor or outdoor security, limited only by imagination and technical skill.
