I'm considering purchasing a video surveilance system for my home. I've just begun my search so excuse my ignorance. I do know I want four outdoor cameras. Beyond that, I'm open to suggestions and input. Any help would be appreciated. I know that higher quality/features requires more money. I really want something simple, that will record day and night and that I can view over the internet while away from home. Costs? Ideas? Best places to buy? Thanks in advance.
