I recently set up a home security CCTV system in my home, as whenever I go away, the local children tend to do damage here. I was away all of last week and I got a call to tell me that the fron of my house was destroyed. I was looking forward to finally catch them in the act, as the house was under surveillance. However, the SD card onto which all the data (avi files) are saved, filled up and contrary to normal removable data card use, when the card was full, it didn’t just stop recording (which I’d expected it to), it went back on the card and began recording over the existing files. As a result, all images from the days the damage was done, is gone. Needless to say, I desperately need to recover these files and need help as soon as I possible. Help!!!
