First Alert Digital Wireless Security Recording System

I purchased the First Alert D575 Security Camera System for at my seasonal campsite. I've had problems with a neighbor lady that has mental problems spraying my bushes with grass & weed killer. The camp grounds manager hasn't done anything about it. So my wife and I decided to catch her doing it on video. Then I plan on calling the State Police and filing charges!! I found the system fairly easy to install. I had it installed in a matter of a couple of minutes. When it came time to set it up; this was another story!!! First Alert advertises it as having "motion activated technology". I had a real problem trying to get it set up for motion activation only!!! There's a setting for X-15sec-10sec-15sec blasts. I couldn't get it to record without being in one of these settings. They sent a 2GB SD Card along with the system. It filled the card up in no time!!! I played around with it for about 3-4 hrs the next day. Still I couldn't get it set up to "motion only". I figured I had better get a larger SD Card if this was going to be the case. The next day I called First Alert to see what the largest size card was I could put in it. The guy at First Alert told me that he thought it was a 2GB SD. After I spoke with him I checked the "Users Manual" and watched one of First Alerts sales videos. The manual said up to a 16GB SD Card will work and the video also said the same thing. I explained my problem of not being able to set it up on "motion activated only" to the guy at First Alert. He told me that there was a "icon" about 12 o'clock that indicated it on the front of the reciever. At the time I only had my "Users Manual" in front of me and that there wasn't any thing like that on the front of the reciever. I was calling him from home at the time. He told me to call him back when I had the unit in front of me. I also told him that there were things like a "Power Saver" mode mentioned in the "Users Manual" but actually I couldn't find that setting on any of the settings!!!! He couldn't tell me what was with that!!! I returned to my camp site. Called this guy back at First Alert but thre was no answer at his office. I decided to play around with it for another hour or so. I found that the "camera" on the remote control has to be clicked on and the red "REC" and the red counter will flash across the TV screen when the motion sensor is activated!!!! When I first clicked this on it appeared that it was video recording all the time. So other users "Be Ware"!!!! First Alert needs to review or revise their "Users Manual"!!!!
