For an initial review I must say this Home Security Camera System is a great investment. The harddrive (not included) was easy to install, and the system's packaging came with the screws needed to secure the harddrive in the DVR. Connecting power, video, mouse, and a camera to test were straight forward. I had some flakiness with the mouse in that it could not be plugged in all the way or it would not work. The connector needed to be pulled out slightly.
After powering up the system for the first time, the camera was recognized and showed video immediately. The system walked you through initial set up (format harddrive, set time, etc, etc.) Re-entering the menu is a breeze (Just hit the F12 button on the front of the DVR, or right click on the screen) There are tons of options to choose from for configuring and fine tuning.
Some of the menus are not intuitive, but after tinkering, figuring out how to record, play back and select files is all easy enough.
I have not permanently installed any of the camera, but the wiring included with each camera seems good and long.
The picture quality on the camera in both daylight and night vision is clear.
For the price, and ease of recording video, I can't beat the extra peace of mind having this system in my house.
