Security Cameras Systems

I’m in need of a good camera security system. I’m not too familiar with the technology. Are there any wireless camera systems? How much do they run for? Is there an option to record the footage directly online to the internet? I need to buy a system asap!

I have recently been looking into home security, surveillance cameras. I don’t know much about cameras and I was looking mostly because I believe we have had people snooping around our house every now and then checking things out. I know I heard voices the other night and I am very worried. I am also afraid however that other people can log into my system and watch me. After all if I can watch if on my pda or computer doesn’t that mean that anyone can watch me? And if anyone knows anything about good camera systems or what brand is good or anything like that please tell me im in the dark.

Sincerely,
Ashley

I want to put a couple of cameras outside my home for safety purposes does anyone know of the best or most cost effective systems
