Beware, multiple HD camera can be taxing on a DVR. With just two of these at 20 fps my system is at 25% all the time.
Just a note about the IE interface and Windows 8. I never could get this camera to work with IE, however with VLC and Firefox all worked perfectly. It was nice to be able to use my tablet while aiming the camera.
Also, the disk that came with this did not have much for instructions or trouble shooting. I was lucky and finally figured out how to read the wps files. All other documentation on the disk was .doc files. By the way, wps files are not firmware, however, my attempt to load one as firmware did not brick the camera.
