We've had some things come up missing lately, and our telephone and high speed lines to our house cut, and was wondering if any of you have any experience with security cameras. I'm looking for a good system, but need to try to keep the cost as low as possible. I have looked on Ebay and Amazon, and found so many that my head is spinning. I'm reading good and bad reviews on just about every system out there. Can anyone help steer me in the right direction? I want night time capabilities, 4 cameras, and I'm not sure if i need a DVR or if I can just use my 6 year old desktop. I am not a tech savvy person to say the least. Any information that anyone can offer of their experience, what to watch out for, or stay clear of, would be greatly appreciated. Thanks, Ron
