If you’re curious about suspicious activity or would like the convenience and security of viewing who is at your front door, then a surveillance system is what you need.
There are plenty of options when it comes to cameras and DVR’s or Digital Video Recorders. When choosing cameras, it all depends on the application, if you want to see near or far, whether you prefer color or black & white, if you want them to be seen or installed covertly, and if the recording time is day / night or both. The wide selection of DVR’s range from basic 80G hard drives to fully programmable multi-gig networkable drives with DVD rewritable capabilities. Basically, your options are endless with a surveillance system.
